Elaine Dazzio" Date: Thu, 16 Apr 2026 15:39:09 -0400 Subject: [PATCH 03/30] Python: Feat: Add finish_reason support to AgentResponse and AgentResponseUpdate (#5211) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add finish_reason support to AgentResponse and AgentResponseUpdate Add finish_reason field to AgentResponse and AgentResponseUpdate classes, propagate it through _process_update() and map_chat_to_agent_update(), and add comprehensive unit tests. Fixes #4622 * feat: add finish_reason to AgentResponse and AgentResponseUpdate * style: add copyright header to test_finish_reason.py * docs: add finish_reason to AgentResponse and AgentResponseUpdate docstrings * refactor: move finish_reason tests into test_types.py per review feedback Move all finish_reason test cases from the separate test_finish_reason.py file into test_types.py as requested by eavanvalkenburg. Tests are placed in a new '# region finish_reason' section at the end of the file. * fix: use model instead of model_id in _process_update Address PR review feedback from @eavanvalkenburg — ChatResponse and ChatResponseUpdate both use 'model', not 'model_id'. * fix: resolve SIM102 lint error in _process_update Combine nested if statements for AgentResponse finish_reason check to satisfy ruff SIM102 rule, with line wrapping to stay under 120 chars. * fix: resolve pyright reportArgumentType in map_chat_to_agent_update Add type: ignore[arg-type] for FinishReason NewType widening when passing ChatResponseUpdate.finish_reason to AgentResponseUpdate.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Foundry Evals integration for .NET - Core evaluation framework: EvalItem, LocalEvaluator, FunctionEvaluator, EvalChecks - IAgentEvaluator interface with MeaiEvaluatorAdapter bridge - AgentEvaluationExtensions for agent.EvaluateAsync() overloads - FoundryEvals wrapping MEAI quality/safety evaluators - ConversationSplitters (LastTurn, Full) and IConversationSplitter - EvalItem.PerTurnItems() for multi-turn decomposition - HasImageContent for multimodal content detection - WorkflowEvaluationExtensions for per-agent workflow evaluation - 7 eval samples mirroring Python parity: 02-agents/Evaluation: SimpleEval, ExpectedOutputs, Multimodal 03-workflows/Evaluation: WorkflowEval 05-end-to-end/Evaluation: FoundryQuality, MixedProviders, ConversationSplits - Comprehensive unit tests (1958 passing) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Rewrite FoundryEvals to use real Foundry Evals API Replace MEAI evaluator shim with actual OpenAI EvaluationClient protocol methods. FoundryEvals now creates eval definitions, submits runs, polls for completion, and fetches per-item results server-side. - New constructor: FoundryEvals(AIProjectClient, model, evaluators) - Add FoundryEvalConverter for MEAI ChatMessage -> Foundry JSON format - Add EvalId, RunId, ReportUrl to AgentEvaluationResults - All 20 built-in evaluator constants now work (agent, tool, quality, safety) - Remove Microsoft.Extensions.AI.Evaluation.Quality/Safety dependencies - Update all samples for new constructor (no more ChatConfiguration) - Replace BuildEvaluators tests with ResolveEvaluator tests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add response output to CustomEvals and ExpectedOutputs samples Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review: pagination, validation, error handling, tests FoundryEvals fixes: - Add pagination for output items (has_more/after cursor) - Add guard clauses for pollIntervalSeconds/timeoutSeconds <= 0 - Fix double TryGetProperty for passed field parsing - Throw on all-tool-evaluators with no tool definitions - Fix XML doc (default 300s, not 180s) New tests (30 added, 1989 total): - EvalChecks: NonEmpty, ContainsExpected (pass/fail/skip/case), HasImageContent, ToolCallsPresent - FoundryEvalConverter: ConvertMessage (text, image, function call, function results fan-out, empty fallback, mixed content), ConvertEvalItem, BuildTestingCriteria (quality/agent/tool/groundedness data mappings), BuildItemSchema Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix review: null-refs, Data.ToString() bug, ContainsExpected, add tests - Fix NullReferenceException in sample Response display (pattern matching) - Fix WorkflowEvaluationExtensions Data?.ToString() producing type names instead of message text (pattern-match ChatMessage/AgentResponse/list) - Change EvalChecks.ContainsExpected to return Passed=false when no ExpectedOutput (was silently passing, masking misconfiguration) - Add EvalItem constructor tests with LastTurn/Full/null splitters - Add FoundryEvalConverter.ConvertMessage DataContent (base64 image) test - Add ExtractAgentData tests with ChatMessage, list, and AgentResponse data Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix review: conversation fidelity, eval caching, fallback tests - WorkflowEvaluationExtensions: preserve full response messages (tool calls, intermediate) instead of synthetic 2-message conversation. Cast completed Data to AgentResponse and use Messages when available, fallback to text. - FoundryEvals: cache evalId per schema shape (hasContext, hasTools) so subsequent EvaluateAsync calls create runs under the same eval definition. - MeaiEvaluatorAdapter: code already correctly passes queryMessages (not full conversation) to IEvaluator — no change needed, verified by inspection. - Add tests: AgentResponse full messages preservation, unknown object ToString() fallback for ExtractAgentData. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Rename AzureAI→Foundry: move eval files, update references - Move FoundryEvals.cs and FoundryEvalConverter.cs from Microsoft.Agents.AI.AzureAI to Microsoft.Agents.AI.Foundry - Update namespace from AzureAI to Foundry in both files - Add explicit usings required by Foundry project (no implicit usings) - Move FoundryEvalConverter tests to Foundry.UnitTests project (avoids ReplacingRedactor type conflict from dual project refs) - Update all sample csproj references and using statements - Remove Foundry project reference from AI UnitTests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * PR review round 4: wire up tool extraction, remove eval cache, fix null safety - BuildEvalItem: extract tools from agent via GetService() into EvalItem.Tools (Python parity) - FoundryEvals: remove eval ID cache - each call creates fresh definition (matches Python behavior) - FoundryEvals: replace null-forgiving operators with descriptive InvalidOperationException - MixedProviders sample: remove unnecessary explicit PackageReferences (transitively provided) - FoundryEvalConverter: document that tool results take precedence over text content - Add LocalEvaluator zero-checks test documenting 0 metrics = failed behavior Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python-dotnet parity: 9 feature gaps filled New checks: - ToolCallArgsMatch() — verify tool call names + argument subset match - ToolCalledCheck(ToolCalledMode.Any, ...) — match any of the specified tools - ToolCalledMode enum (All/Any) FoundryEvals enhancements: - Default evaluators now [Relevance, Coherence, TaskAdherence] (was Relevance, Coherence) - Auto-add ToolCallAccuracy when items have tool definitions - EvaluateTracesAsync — evaluate by response_ids, trace_ids, or agent_id - EvaluateFoundryTargetAsync — evaluate deployed Foundry targets Result type enrichment: - AgentEvaluationResults: added Status, Error, PerEvaluator, DetailedItems - New EvalItemResult/EvalScoreResult/PerEvaluatorResult types - FoundryEvals populates all new fields from API responses Workflow fix: - Skip internal executors (_*, input-conversation, end-conversation, end) Tests: 8 new tests covering ToolCallArgsMatch, ToolCalledMode.Any, internal executor filtering Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add MeaiEvaluatorAdapter and PerTurnItems edge case tests - 3 tests for MeaiEvaluatorAdapter: query message forwarding, synthetic response fallback, multiple items aggregation - 3 tests for EvalItem.PerTurnItems: empty conversation, no user messages, system+assistant only - StubEvaluator and StubChatClient test helpers Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Blocking link check for outdated package in DevUI. * Replace Dictionary payloads with typed wire models Introduce internal FoundryEvalWireModels.cs with compile-time-safe types for the OpenAI Evals API wire format. The OpenAI .NET SDK (2.9.1) only provides protocol-level methods with BinaryContent/ClientResult — no typed request models. These internal models replace scattered dictionary literals with [JsonPropertyName]-annotated classes, giving: - Compile-time safety (typos become build errors) - Single point of change when the API evolves - IntelliSense discoverability - Cleaner serialization via JsonPolymorphic for content items Models: WireContentItem hierarchy (text, image, tool_call, tool_result), WireMessage, WireEvalItemPayload, WireTestingCriterion, WireItemSchema, WireCreateEvalRequest, WireCreateRunRequest, and data source variants. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Skip metric when Foundry returns neither score nor passed When an evaluator returns no score and no passed value, the previous code created BooleanMetric(name, false), which falsely failed items via ItemPassed. Now we skip the MEAI metric entirely for indeterminate results — the raw data remains available in DetailedItems for diagnostics. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR #4914 review comments: fix tool evaluator bug and add tests - Fix duplicate ToolCallAccuracy: resolve evaluator names before checking against ToolEvaluators set (Comment 2) - Make FilterToolEvaluators internal for testability; add tests for the ArgumentException edge case when all evaluators are tool-type (Comment 3) - Add CancellationToken test for LocalEvaluator (Comment 4) - Add EvaluateAsync integration test on Run with sequential workflow and per-agent SubResults verification (Comment 5) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address Peter's review comments on PR #4914 - Add trailing newline to Evaluation_FoundryQuality.csproj (Comment 6) - Make evaluator name lookups case-insensitive: switch BuiltinEvaluators, ToolEvaluators, AgentEvaluators, and ResolveEvaluator's StartsWith check from Ordinal to OrdinalIgnoreCase (Comment 7) - Add Trace.TraceWarning when Foundry returns fewer results than submitted items, indicating expected vs actual count before padding (Comment 8) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add Microsoft.Extensions.AI.Evaluation packages to Directory.Packages.props These were removed in #5269 as unused, but are needed by the Foundry and core evaluation integration added in this PR.

Instead of requiring a separate model round-trip for every tool call, conditional branch, or data transformation, the model produces a short program that runs in a controlled runtime, calls host-provided tools through a `call_tool(...)` bridge, and returns structured results. This reduces latency, lowers token cost, and lets the model express richer multi-step logic that is difficult to capture in a flat tool-call sequence. + +Throughout this ADR, **CodeAct** is the primary term. **Code mode** and **programmatic tool calling** refer to the same capability. + +## Context and Problem Statement + +We need an architecture design that supports CodeAct in both Python and .NET. This is a necessary capability for the current generation of long-running agents, which need to plan, iterate, transform tool outputs, and execute bounded code inside a controlled runtime — for example, filtering a large result set, computing derived values, or chaining several tool calls with conditional logic — instead of requiring a separate model round-trip for each of those steps. The design should preserve the same behavioral contract across SDKs, but it does not need to use the same internal extension point in each runtime. We also want to standardize on Hyperlight as the initial backend, using the existing Python package and an anticipated .NET binding package once it is available. + +Throughout this ADR, **CodeAct** is the primary term. **Code mode** and **programmatic tool calling** refer to the same capability. This ADR uses **CodeAct** consistently. + +Model-generated code is treated as untrusted relative to the host process. This ADR assumes the selected backend provides the primary isolation boundary, while the framework is responsible for configuring approvals and capabilities, integrating telemetry, and translating outputs and failures into framework-native shapes. If a backend cannot provide isolation appropriate for its trust model, it is not a suitable CodeAct backend. + +The core design question is: **where should CodeAct integrate into the agent pipeline so that both SDKs can offer the same functionality without invasive changes to their core function-calling loops?** + +## Decision Drivers + +- CodeAct must shape the model-facing surface before model invocation, not only after the model has already chosen tools. +- The design should let users control which tools are available through CodeAct and which remain regular tools only. +- The design must preserve existing session, approval, telemetry, and tool invocation behavior as much as possible. +- The design should define the minimum cross-SDK telemetry and failure semantics for `execute_code`, so Python and .NET do not diverge on basic observability or error handling. +- The design must fit naturally into the extension points that already exist in each SDK. +- The design must be safe for concurrent runs and must not rely on mutating shared agent configuration during invocation. +- The chosen structure should allow multiple backend-specific providers to fit under the same conceptual design over time, even though Hyperlight is the initial target. +- The abstraction should not assume that every backend is a VM-style sandbox; alternative execution models such as Pydantic's Monty should also fit. +- The design should allow `execute_code` to be reused both as a tool-enabled CodeAct runtime and as a standard code interpreter tool implementation. +- The design should remain open to alternative language/runtime modes, such as JavaScript on Hyperlight, rather than baking the abstraction to Python only. +- The design should provide a portable way to configure sandbox capabilities such as file access and network access, including allow-listed outbound domains. +- Using CodeAct should be optional, and installing its runtime or backend dependencies should also be optional. +- Backend-specific dependencies should be isolated behind a small adapter so SDK code is not tightly coupled to an unstable package surface. + +## Considered Options + +- **Option 1**: Standardize on context provider-based CodeAct with a shared cross-SDK contract and backend-specific public types +- **Option 2**: Implement CodeAct as a dedicated chat-client decorator/wrapper +- **Option 3**: Integrate CodeAct directly into the function invocation layer/FunctionInvokingChatClient + +## Pros and Cons of the Options + +### Option 1: Standardize on context provider-based CodeAct with a shared cross-SDK contract and backend-specific public types + +This option uses `ContextProvider` in Python and `AIContextProvider` in .NET, but standardizes the public concept and behavior. +In this option, the CodeAct tool set is provider-owned: only tools explicitly configured on the concrete CodeAct provider instance are available inside CodeAct, and the provider exposes direct CRUD-style management for tools, file mounts, and outbound network allow-list configuration rather than requiring a separate runtime setup object. +The agent's direct tool surface remains separate. If a tool should be available both through CodeAct and as a normal direct tool, it is configured in both places. + +- Good, because both SDKs already have first-class provider concepts intended for per-invocation context shaping. +- Good, because providers operate before model invocation, which is where CodeAct must add instructions and reshape tools. +- Good, because this lets us preserve existing function invocation behavior rather than rewriting it. +- Good, because slightly different internals are acceptable while the public behavior remains aligned. +- Good, because convenience builder/decorator helpers can still be added later on top of the provider model without changing the core design. +- Good, because backend-specific runtime logic can stay inside concrete provider implementations or internal helpers instead of being forced into a lowest-common-denominator public abstraction. +- Good, because the same provider structure can support either an all-or-nothing tool surface or a mixed side-by-side tool surface. +- Good, because users can keep some tools direct-only while allowing other tools to be used from inside CodeAct. +- Good, because a provider-owned CodeAct tool registry avoids mutating or inferring the agent's direct tool surface and can work consistently in both SDKs. +- Good, because the same conceptual design can remain open to `HyperlightCodeActProvider`, a future `MontyCodeActProvider`, and other backend-specific providers over time. +- Good, because `execute_code` can evolve into multiple backend-specific runtime modes rather than being hard-wired to one Python-plus-tools mode. +- Bad, because the provider indirection adds per-run overhead — snapshotting the tool registry, dispatching lifecycle hooks, and building instructions — that a deeper integration point could skip. In practice this overhead is negligible relative to model inference latency and sandbox startup cost. + +### Option 2: Implement CodeAct as a dedicated chat-client decorator/wrapper + +This option would introduce a CodeAct-specific chat-client decorator that injects instructions and tools directly into the chat request pipeline. + +- Good, because this is a natural fit for .NET's `DelegatingChatClient` pipeline. +- Good, because it can also support advanced custom chat-client stacks. +- Good, because backend-specific runtime selection could be hidden inside the decorator implementation. +- Good, because the decorator could also encapsulate mode-specific instruction shaping for tool-enabled versus standalone interpreter behavior. +- Good, because the decorator can decide per request whether the tool surface is exclusive or mixed. +- Bad, because Python can support this by building a custom layering stack on top of a `Raw...Client` and swapping in a different `FunctionInvocationLayer`, but that composition path is more manual than the .NET `DelegatingChatClient` pipeline. +- Bad, because it duplicates responsibilities already handled by provider abstractions. +- Bad, because it makes CodeAct look more transport-specific than it really is. +- Bad, because swappable backends and reusable interpreter or language modes become coupled to chat-client composition rather than modeled as first-class CodeAct concepts. + +### Option 3: Integrate CodeAct directly into the function invocation layer/FunctionInvokingChatClient + +This option would push CodeAct into Python's `FunctionInvocationLayer` and .NET's `FunctionInvokingChatClient` or related middleware. + +- Good, because it is close to tool execution and can observe concrete tool invocation behavior. +- Good, because function middleware may still be useful later for auxiliary auditing or policy around sandbox-originated tool calls. +- Bad, because this is the wrong layer for constructing the model-facing tool surface and prompt instructions. +- Bad, because it does not naturally control whether the model sees an exclusive CodeAct tool surface or a mixed side-by-side tool surface. +- Bad, because it would still require a second mechanism for hiding normal tools and advertising `execute_code`. +- Bad, because it is a weak fit for standalone interpreter modes where no tool-calling loop is needed. +- Bad, because backend selection and CodeAct mode behavior are orthogonal concerns that do not belong in the function invocation layer. +- Bad, because `.NET` would become more tightly coupled to `FunctionInvokingChatClient`, which sits below the agent framework abstraction and is not the natural cross-SDK design seam. + +## Approval Model Options + +- **Option A**: Bundled approval for the `execute_code` invocation +- **Option B**: Pre-execution inspection of `call_tool(...)` references before approving `execute_code` +- **Option C**: Nested per-tool approvals during `execute_code` + +## Pros and Cons of the Approval Options + +### Option A: Bundled approval for the `execute_code` invocation + +This option grants approval once, before `execute_code` starts. Provider-owned tool calls made from inside that execution run under the same approval. The effective approval of `execute_code` is determined up front from the provider configuration rather than from inspecting which tools are actually called during execution. + +- Good, because it is the simplest model to explain and implement consistently in both SDKs. +- Good, because it fits naturally with long-running CodeAct loops where repeated approval interruptions would be disruptive. +- Good, because it does not require static code analysis before execution begins. +- Good, because it keeps the first release focused on the provider integration rather than a more complex approval engine. +- Bad, because approval is coarse-grained and may cover more activity than the user expected. +- Bad, because it provides less visibility into which provider-owned tools or capabilities will be exercised during the run. + +### Option B: Pre-execution inspection of `call_tool(...)` references before approving `execute_code` + +This option inspects submitted code for statically discoverable `call_tool("tool_name", ...)` references before execution starts and uses that information to shape the approval request. + +- Good, because it can show users more detail up front while still keeping approval at a single pre-execution moment. +- Good, because it matches the common case where tool names are spelled out directly in the generated code. +- Good, because it can coexist with bundled approval as a more informative variant of the same UX. +- Bad, because the analysis is inherently best-effort and cannot reliably predict dynamic behavior. +- Bad, because it requires duplicated parsing or inspection logic that does not replace runtime enforcement. + +### Option C: Nested per-tool approvals during `execute_code` + +This option requests approval when sandboxed code actually attempts to invoke a provider-owned tool that requires approval. + +- Good, because it aligns approval with real behavior rather than predicted behavior. +- Good, because it gives precise visibility into which provider-owned tools are being used. +- Good, because it can allow some tool calls while rejecting others within the same execution. +- Bad, because it interrupts long-running CodeAct flows and can degrade the user experience significantly. +- Bad, because it requires more complex runtime plumbing and approval UX in both SDKs. +- Bad, because repeated approval pauses may make CodeAct less useful for the exact long-running scenarios that motivate this feature. + +## Decision Outcomes + +### Decision 1: Integration seam and public structure + +Chosen option: **Option 1: Standardize on provider-based CodeAct with a shared cross-SDK contract and backend-specific public types**, because it is the only option that maps cleanly to both SDKs, lets us reshape instructions and tools before model invocation, and avoids invasive changes to the existing function invocation loops while still allowing multiple backend-specific providers and multiple runtime modes to fit under the same structure later. + +### Decision 2: Initial approval model + +Chosen option: **Option A: Bundled approval for the `execute_code` invocation**, because it is the smallest approval model that fits both SDKs, works well for long-running CodeAct flows, and does not force us to standardize a more complex inspection or policy engine in the first release. + +This follows the spirit of the current Python tool approval flow, where `FunctionTool` uses `approval_mode="always_require" | "never_require"` and the auto-invocation loop escalates the whole batch when any called tool requires approval. + +### Design summary + +We standardize the **public concept** of CodeAct across SDKs while allowing each SDK to use the extension point that fits it best. + +- Python uses a `ContextProvider`. +- .NET uses an `AIContextProvider`. +- The term **CodeAct context provider** is used throughout this ADR as a design concept, not as a required public base type. Public SDK APIs should prefer concrete backend-specific types such as `HyperlightCodeActProvider` rather than a public abstract `CodeActContextProvider` or a public `CodeActExecutor` parameter. +- CodeAct support should ship as an optional package in each SDK rather than as part of the core package, so users who do not need CodeAct do not take on its installation and dependency footprint. That optional package may still depend on a few small, backward-compatible hooks in the host SDK's core agent pipeline. +- There is no separate runtime setup object in the chosen design. Concrete providers manage their provider-owned CodeAct tool registry, file mounts, and outbound network allow-list configuration directly through CRUD-style methods on the provider itself. +- At a high level, CodeAct is exposed through backend-specific context providers that contribute an `execute_code` tool, own the CodeAct-specific tool registry, and carry backend capability configuration such as filesystem and network access. +- The initial approval model is bundled approval for `execute_code`, using the same `approval_mode="always_require" | "never_require"` vocabulary as regular tools. +- The CodeAct provider exposes a default `approval_mode` for `execute_code`. If the provider default is `always_require`, `execute_code` is always treated as `always_require` regardless of the provider-owned tool registry. If the provider default is `never_require`, the effective approval for `execute_code` is derived from the provider-owned CodeAct tool registry captured for the run. +- If every provider-owned CodeAct tool in that registry has `approval_mode="never_require"`, `execute_code` is treated as `never_require`. If any provider-owned CodeAct tool in that registry has `approval_mode="always_require"`, `execute_code` is treated as `always_require`, even if the generated code may not end up calling that tool. +- Approval is granted before `execute_code` starts, and provider-owned tool calls made from inside that execution run under the same approval. +- Direct-only agent tools do not affect the approval of `execute_code`; only the provider-owned CodeAct tool registry participates in that calculation. +- This approval model is intentionally conservative. If one sensitive provider-owned tool forces `execute_code` to require approval more often than desired, the mitigation is to keep that tool direct-only or split it into a different provider/tool surface rather than trying to infer per-run tool usage up front. +- Configuring filesystem and network capability state on the provider, including adding file mounts or outbound network allow-list entries, is itself the approval for those capabilities in the initial model. +- Each `execute_code` invocation must start from a clean execution state; in-memory variables and other ephemeral interpreter/runtime state must not persist across separate calls. When a provider exposes a workspace, mounted files, or a writable artifact/output area, those files are the supported persistence mechanism across calls and are treated as external state rather than interpreter state. +- Mutating the provider's tool registry or capability configuration while a run is in flight is allowed, but it only affects subsequent runs. Provider implementations must snapshot the effective state for each run and synchronize concurrent access so shared provider instances remain safe across concurrent runs. +- The minimum cross-SDK telemetry contract is that `execute_code` is traced as a normal tool invocation nested inside the surrounding agent run, and provider-owned tool calls made from inside CodeAct continue to emit ordinary tool-invocation telemetry. Backend-specific resource metrics are optional extensions, not a required new top-level cross-SDK event model. +- Timeout, out-of-memory, backend crash, and similar sandbox failures are all execution failures of `execute_code` and should surface as structured error results rather than backend-specific public DTOs. Partial textual or file outputs may be returned only when the backend can report them unambiguously; callers must not rely on partial-output recovery as a portable guarantee. +- The provider-based structure preserves room for future pre-execution inspection and nested per-tool approvals if later experience shows they are needed. +- Concrete backend-specific providers may still use small SDK-local helpers or adapters internally, but that split is an implementation detail rather than a public API requirement. + +Detailed language-specific implementation notes are specified in: + +- [Python implementation](../features/code_act/python-implementation.md) +- [.NET implementation](../features/code_act/dotnet-implementation.md) + +### Minimal core hooks required by the optional package + +CodeAct remains optional at the package level, but the optional package depends on a small number of hooks that must live in the host SDK because the agent pipeline owns model invocation and per-run tool resolution. + +- Python depends on the existing `ContextProvider` lifecycle, `SessionContext.extend_instructions(...)`, `SessionContext.extend_tools(...)`, per-run runtime tool access via `SessionContext.options["tools"]`, and the shared `ApprovalMode` vocabulary used by `FunctionTool`. +- .NET depends on the existing `AIContextProvider` seam, agent/runtime support for applying providers before model invocation, and the existing chat-client or function-invocation seams that concrete implementations use to contribute `execute_code`. + +These hooks are backward-compatible because they only expose or forward per-run state that core already owns. Behavior changes only when a concrete CodeAct provider opts in and uses them. + +### Concrete provider implementation contract + +The design does not require a public abstract `CodeActContextProvider` base class, but it does require a stable implementation contract for concrete providers. + +- Concrete providers should expose a standard capability surface at construction time, with SDK-appropriate naming for: + - approval mode + - workspace root + - file mounts + - allowed outbound targets plus any per-target method or policy restrictions needed by the backend +- Separate public `filesystem_mode` / `network_mode` flags are not required by the cross-SDK contract. Filesystem access may be disabled implicitly until a workspace or file mounts are configured, and outbound network may be disabled implicitly until an allow-list or equivalent outbound policy entry is configured. +- Concrete providers should expose direct CRUD-style methods for managing the provider-owned CodeAct tool registry, file mounts, and outbound network allow-list configuration, rather than requiring callers to construct a separate runtime setup object. +- Concrete providers should implement their host SDK's provider lifecycle hooks to: + - build CodeAct instructions, + - add `execute_code`, + - snapshot the effective CodeAct tool registry and capability settings for the run, + - compute the effective approval requirement for `execute_code`, + - configure file access and network access for the backend, + - prepare or restore execution state, + - execute code, + - and translate backend output into framework-native content. +- Any internal abstract/helper surface shared by multiple concrete providers should standardize responsibilities for: + - instruction construction, + - file-access configuration, + - network-access configuration, + - environment preparation/restoration, + - code execution, + - and output-to-content conversion. +- Backend execution output should reuse existing framework-native content/message primitives rather than introducing backend-specific public result DTOs. + +## More Information + +### Related artifacts + +- Python implementation: [`docs/features/code_act/python-implementation.md`](../features/code_act/python-implementation.md) +- .NET implementation: [`docs/features/code_act/dotnet-implementation.md`](../features/code_act/dotnet-implementation.md) +- Python provider/session APIs: [`python/packages/core/agent_framework/_sessions.py`](../../python/packages/core/agent_framework/_sessions.py) +- Python function invocation loop: [`python/packages/core/agent_framework/_tools.py`](../../python/packages/core/agent_framework/_tools.py) +- .NET context provider abstraction: [`dotnet/src/Microsoft.Agents.AI.Abstractions/AIContextProvider.cs`](../../dotnet/src/Microsoft.Agents.AI.Abstractions/AIContextProvider.cs) +- .NET agent integration for context providers: [`dotnet/src/Microsoft.Agents.AI/ChatClient/ChatClientAgent.cs`](../../dotnet/src/Microsoft.Agents.AI/ChatClient/ChatClientAgent.cs) +- Optional .NET chat-client provider decorator: [`dotnet/src/Microsoft.Agents.AI/AIContextProviderDecorators/AIContextProviderChatClient.cs`](../../dotnet/src/Microsoft.Agents.AI/AIContextProviderDecorators/AIContextProviderChatClient.cs) +- .NET function invocation middleware seam: [`dotnet/src/Microsoft.Agents.AI/FunctionInvocationDelegatingAgentBuilderExtensions.cs`](../../dotnet/src/Microsoft.Agents.AI/FunctionInvocationDelegatingAgentBuilderExtensions.cs) + +### Related decisions + +- [0015-agent-run-context](0015-agent-run-context.md) +- [0016-python-context-middleware](0016-python-context-middleware.md) diff --git a/docs/features/code_act/dotnet-implementation.md b/docs/features/code_act/dotnet-implementation.md new file mode 100644 index 0000000000..5a2b51ae3a --- /dev/null +++ b/docs/features/code_act/dotnet-implementation.md @@ -0,0 +1,625 @@ +# CodeAct .NET implementation + +This document describes the .NET realization of the CodeAct design in +[`docs/decisions/0024-codeact-integration.md`](../../decisions/0024-codeact-integration.md). + +This document is intentionally focused on the .NET design and public API surface. +The initial public .NET type described here is `HyperlightCodeActProvider`.

Computes the effective approval requirement for `execute_code` from the provider default plus the snapshotted tool registry. +3. Builds provider-defined instructions. +4. Builds a run-scoped `execute_code` `AIFunction` from the snapshot (optionally wrapped in `ApprovalRequiredAIFunction`). +5. Returns an `AIContext` containing the instructions and `execute_code` tool. +6. When `execute_code` is invoked by the model, the run-scoped function creates or reuses an execution environment. +7.

Provider implementations synchronize state capture and CRUD operations so shared provider instances remain safe across concurrent runs. + +#### AIFunction-to-sandbox tool bridging + +The Hyperlight sandbox's `RegisterTool(name, Func)` accepts a synchronous JSON-in / JSON-out delegate. Provider-owned CodeAct tools are `AIFunction` instances that are async and cancellation-aware. + +Bridging strategy: +- At sandbox initialization time, the provider registers each CodeAct-managed tool with the sandbox using the raw JSON overload: `RegisterTool(name, Func)`. +- When the sandbox guest calls `call_tool("name", ...)`, the bridge delegate: + 1. Deserializes the JSON arguments. + 2. Invokes `AIFunction.InvokeAsync(...)` synchronously (via `GetAwaiter().GetResult()`) since the sandbox FFI callback is inherently synchronous. + 3. Serializes the result back to JSON. +- This sync-over-async bridge is a known pragmatic trade-off constrained by the Hyperlight FFI boundary. It is safe because: + - Sandbox execution already runs on the thread pool (via `Task.Run`). + - The FFI callback runs on a worker thread with no synchronization context. +- If the Hyperlight .NET SDK later adds async tool registration, the bridge should migrate to that. + +#### Runtime behavior + +- `ProvideAIContextAsync(...)` adds a short CodeAct guidance block through `AIContext.Instructions`. +- `ProvideAIContextAsync(...)` adds `execute_code` through `AIContext.Tools`. +- The detailed `call_tool(...)`, sandbox-tool, and capability guidance is carried by the `execute_code` function's `Description`. +- `execute_code` invokes the configured Hyperlight sandbox guest. +- If the current CodeAct tool registry snapshot is non-empty, the runtime injects `call_tool(...)` bound to the provider-owned tool registry. +- The provider does not inspect or mutate the agent's `ChatClientAgentOptions.Tools` or the incoming `AIContext.Tools` to determine its CodeAct tool set. +- The provider snapshots the current CodeAct tool registry and capability state at run start, so later registry and allow-list mutations only affect future runs. +- Interpreter versus tool-enabled behavior is derived from the presence of CodeAct-managed tools. +- `execute_code` is traced like a normal tool invocation within the surrounding agent run. + +#### Backend integration + +Initial public provider: +- `HyperlightCodeActProvider` + +Backend-specific notes: +- **Hyperlight** + - The provider internally creates a `SandboxBuilder` from the options and uses the `Sandbox` API from `HyperlightSandbox.Api`. + - The provider uses snapshot/restore to ensure clean execution state per `execute_code` invocation: a "warm" snapshot is taken after the first no-op initialization run, and restored before each subsequent execution. + - File access maps to Hyperlight Sandbox's `WithInputDir()` / `WithOutputDir()` / `WithTempOutput()` capability model. + - Network access is denied by default and is enabled through `Sandbox.AllowDomain(...)` per-target allow-list entries. + - Guest module resolution: if `ModulePath` is null for the Wasm backend, the provider attempts to locate a packaged Python guest module (equivalent to the Python SDK's `python_guest.path` resolution). + +#### Capability handling + +Capabilities are first-class `HyperlightCodeActProviderOptions` properties and provider-managed CRUD surfaces: +- `WorkspaceRoot` +- `FileMounts` +- `AllowedDomains` + +Enabling access means: +- Configuring `WorkspaceRoot` or any `FileMounts` enables the sandbox filesystem surface exposed through `/input` and `/output`. +- Leaving both `WorkspaceRoot` and `FileMounts` unset means no filesystem surface is configured. +- Adding any `AllowedDomains` entry enables outbound access only for the configured targets; leaving it empty means network access is disabled without a separate network mode flag. + +Backends may implement stricter semantics than these top-level settings. + +#### Execution output representation + +Backend execution output maps to a JSON result string returned from the `execute_code` `AIFunction`: + +```json +{ + "stdout": "Hello world\n", + "stderr": "", + "exit_code": 0, + "success": true +} +``` + +Execution failures should surface readable error text in the `stderr` field and a non-zero `exit_code`. Timeouts, out-of-memory conditions, backend crashes, and similar sandbox failures are all `execute_code` failures and should surface as structured error results. Partial textual or file outputs may be returned only when the backend can report them unambiguously. + +#### `execute_code` input contract + +```json +{ + "type": "object", + "properties": { + "code": { + "type": "string", + "description": "Code to execute using the provider's configured backend/runtime behavior." + } + }, + "required": ["code"] +} +``` + +#### Thread safety and concurrency + +- All CRUD methods (`AddTools`, `RemoveTools`, `AddFileMounts`, etc.) are synchronized via an internal lock. +- `ProvideAIContextAsync(...)` acquires the lock to snapshot current state, then releases it before building the run-scoped function. The run-scoped function closes over the immutable snapshot, not mutable provider state. +- Concurrent `execute_code` invocations from different runs use independent sandbox instances or synchronized access to a shared sandbox with snapshot/restore. +- Workspace directories (`WorkspaceRoot`, `FileMounts`) are external shared state: concurrent runs against the same workspace can race on files. This is the user's responsibility to manage (e.g., by using per-run output directories or separate provider instances). + +### HyperlightExecuteCodeFunction + +The provider package also exports a standalone `HyperlightExecuteCodeFunction` for direct-tool scenarios where a provider lifecycle is not needed. This is the .NET equivalent of the Python `HyperlightExecuteCodeTool`. + +```csharp +/// +/// A standalone execute_code AIFunction backed by a Hyperlight sandbox. +/// Use this for manual/static wiring when the AIContextProvider lifecycle +/// is not needed. +/// +public sealed class HyperlightExecuteCodeFunction : IDisposable +{ + /// + /// Creates a new standalone code execution function. + /// + /// Configuration options. + public HyperlightExecuteCodeFunction(HyperlightCodeActProviderOptions options); + + /// + /// Returns this as an AIFunction for direct registration on an agent. + /// When approval is required, the returned function is wrapped in + /// ApprovalRequiredAIFunction. + /// + public AIFunction AsAIFunction(); + + /// + /// Builds a CodeAct instruction string describing the available + /// tools and capabilities. + /// + /// + /// When false, the instructions include full tool descriptions + /// (for use when tools are only accessible through CodeAct). + /// When true, instructions are abbreviated (tools are already + /// visible to the model as direct tools). + /// + public string BuildInstructions(bool toolsVisibleToModel = false); + + /// Releases sandbox resources. + public void Dispose(); +} +``` + +### Internal implementation structure + +The provider and standalone function share internal helpers: + +``` +Microsoft.Agents.AI.Hyperlight/ +├── HyperlightCodeActProvider.cs // AIContextProvider implementation +├── HyperlightCodeActProviderOptions.cs // Options record +├── HyperlightExecuteCodeFunction.cs // Standalone AIFunction for manual wiring +├── FileMount.cs // File mount record +├── AllowedDomain.cs // Network allow-list record +├── CodeActApprovalMode.cs // Approval enum +├── Internal/ +│ ├── SandboxExecutor.cs // Manages sandbox lifecycle, snapshot/restore +│ ├── InstructionBuilder.cs // Builds CodeAct instruction strings +│ └── ToolBridge.cs // AIFunction ↔ Sandbox.RegisterTool adapter +``` + +`SandboxExecutor` encapsulates: +- Creating and configuring a `Sandbox` from options. +- Performing the initial no-op warm-up and snapshot. +- Registering bridged tools via `ToolBridge`. +- Restoring to the clean snapshot before each execution. +- Translating `ExecutionResult` to a JSON string. + +`InstructionBuilder` generates: +- A short CodeAct guidance block for `AIContext.Instructions`. +- A detailed `execute_code` description including `call_tool(...)` signatures and capability documentation. + +`ToolBridge` handles: +- Reflecting `AIFunction` metadata to build the sandbox tool registration. +- The sync-over-async invocation bridge. + +## E2E Code Samples + +### Tool-enabled CodeAct mode + +```csharp +var fetchDocs = AIFunctionFactory.Create(FetchDocs, name: "fetch_docs"); +var queryData = AIFunctionFactory.Create(QueryData, name: "query_data"); +var lookupUser = AIFunctionFactory.Create(LookupUser, name: "lookup_user"); + +var codeact = new HyperlightCodeActProvider(new HyperlightCodeActProviderOptions +{ + Tools = [fetchDocs, queryData], + WorkspaceRoot = "./workdir", + AllowedDomains = [new AllowedDomain("api.github.com", ["GET"])], +}); +codeact.AddTools(lookupUser); + +var sendEmail = AIFunctionFactory.Create(SendEmail, name: "send_email"); + +var agent = chatClient.AsAIAgent( + instructions: "You are a helpful assistant.", + options: new ChatClientAgentOptions + { + Tools = [sendEmail], // direct-only tool + AIContextProviders = [codeact], + }); + +await using var session = await agent.CreateSessionAsync(); +var response = await agent.InvokeAsync("Analyze the latest docs", session); +``` + +### Standard code interpreter mode + +```csharp +var codeact = new HyperlightCodeActProvider(new HyperlightCodeActProviderOptions +{ + WorkspaceRoot = "./data", +}); + +var agent = chatClient.AsAIAgent( + instructions: "You are a code interpreter.", + options: new ChatClientAgentOptions + { + AIContextProviders = [codeact], + }); +``` + +### Manual static wiring (no provider lifecycle) + +When the tool registry and capability configuration are fixed, the provider lifecycle can be skipped entirely.

Key types consumed from that SDK: + +| hyperlight-sandbox type | Used for | +|---|---| +| `Sandbox` | Core sandbox lifecycle: `Run()`, `RegisterTool()`, `AllowDomain()`, `Snapshot()`, `Restore()` | +| `SandboxBuilder` | Fluent sandbox construction from provider options | +| `SandboxBackend` | Backend selection (Wasm, JavaScript) | +| `ExecutionResult` | Capturing stdout, stderr, exit code from guest execution | +| `SandboxSnapshot` | Checkpoint/restore for clean state per execution | + +The provider package (`Microsoft.Agents.AI.Hyperlight`) takes a NuGet dependency on `Hyperlight.HyperlightSandbox.Api` and `Microsoft.Extensions.AI.Abstractions`. It does **not** depend on `HyperlightSandbox.Extensions.AI` (`CodeExecutionTool`) — the provider implements its own sandbox lifecycle management with run-scoped snapshots to support concurrent invocations safely. + +## Package structure + +The CodeAct Hyperlight provider ships as an optional NuGet package: +- **Package**: `Microsoft.Agents.AI.Hyperlight` +- **Dependencies**: + - `Microsoft.Agents.AI.Abstractions` (for `AIContextProvider`, `AIContext`) + - `Microsoft.Extensions.AI.Abstractions` (for `AIFunction`, `ApprovalRequiredAIFunction`) + - `Hyperlight.HyperlightSandbox.Api` (for sandbox API) +- **Target framework**: `net8.0` + +This keeps CodeAct and its native sandbox dependencies optional — users who do not need CodeAct do not take on the Hyperlight installation and dependency footprint. + +## Open questions + +1. **Guest module distribution**: How should the default Python guest module (`.aot` file) be distributed for .NET consumers? Options include a separate NuGet package with native assets, a runtime download, or requiring users to build/provide their own. +2. **Async tool registration**: If the Hyperlight .NET SDK adds async tool callback support in a future release, the sync-over-async bridge should be replaced. This is tracked as a known technical debt item. +3. **Output file access**: The Hyperlight sandbox exposes `GetOutputFiles()` and `OutputPath` for retrieving files written by guest code. The initial design returns these as part of the JSON result. A future iteration could surface output files as framework-native content (e.g., `DataContent` or URI references). +4. **Multiple sandbox instances for concurrency**: The current design uses synchronized access to a single sandbox with snapshot/restore. An alternative pooling strategy (one sandbox per concurrent run) could improve throughput at the cost of memory. This is deferred to implementation time. diff --git a/docs/features/code_act/python-implementation.md b/docs/features/code_act/python-implementation.md new file mode 100644 index 0000000000..7f45190d33 --- /dev/null +++ b/docs/features/code_act/python-implementation.md @@ -0,0 +1,385 @@ +# CodeAct Python implementation + +This document describes the Python realization of the CodeAct design in +[`docs/decisions/0024-codeact-integration.md`](../../decisions/0024-codeact-integration.md). + +This document is intentionally focused on the Python design and public API surface. +The initial public Python type described here is `HyperlightCodeActProvider`.

CodeAct tools, file mounts, and outbound network allow-list state are managed directly on the provider through CRUD-style registry methods. + +Preferred pattern: +- `add_tools(...) -> None` +- `get_tools() -> Sequence[ToolTypes]` +- `remove_tool(...) -> None` +- `clear_tools() -> None` +- `add_file_mounts(...) -> None` +- `get_file_mounts() -> Sequence[FileMount]` +- `remove_file_mount(...) -> None` +- `clear_file_mounts() -> None` +- `add_allowed_domains(...) -> None` +- `get_allowed_domains() -> Sequence[AllowedDomain]` +- `remove_allowed_domain(...) -> None` +- `clear_allowed_domains() -> None` + +Requirements: +- The provider-owned CodeAct tool registry is keyed by tool name. +- `add_tools(...)` adds new tools and replaces an existing provider-owned registration when the same tool name is added again. +- `get_tools()` returns the provider's current configured CodeAct tool registry. +- `remove_tool(...)` removes provider-owned CodeAct tools by name. +- `clear_tools()` removes all provider-owned CodeAct tools. +- File mounts are keyed by sandbox mount path. +- `add_file_mounts(...)` adds new file mounts and replaces an existing mount when the same mount path is added again. +- `get_file_mounts()` returns the provider's current configured file mounts. +- `remove_file_mount(...)` removes file mounts by mount path. +- `clear_file_mounts()` removes all configured file mounts. +- Allowed domains are keyed by normalized target string. +- `add_allowed_domains(...)` adds allow-list entries and replaces an existing entry when the same target is added again. +- `get_allowed_domains()` returns the current outbound allow-list entries. +- `remove_allowed_domain(...)` removes allow-list entries by target. +- `clear_allowed_domains()` removes all configured allow-list entries. +- Tool, file-mount, and network-allow-list mutations affect subsequent runs only; runs already in progress keep the snapshot captured at run start. +- The provider must snapshot its effective tool registry and capability state at the start of each run so concurrent execution remains deterministic. + +#### Approval model + +The initial Python design follows the ADR's initial approval decision and reuses the existing tool approval vocabulary from `agent_framework._tools`: + +- `approval_mode="always_require"` +- `approval_mode="never_require"` + +The provider exposes a default `approval_mode` for `execute_code`. + +Effective `execute_code` approval is computed as follows: + +- If the provider default is `always_require`, `execute_code` requires approval. +- If the provider default is `never_require`, the provider evaluates the provider-owned CodeAct tool registry snapshot for that run. +- If every provider-owned CodeAct tool in that snapshot is `never_require`, `execute_code` is `never_require`. +- If any provider-owned CodeAct tool in that snapshot is `always_require`, `execute_code` is `always_require`, even if the generated code may not call that tool. +- Provider-owned tool calls made through `call_tool(...)` during that execution run use the approval already determined for `execute_code`. +- Direct-only agent tools are excluded from this calculation. +- File and network capabilities do not create a separate runtime approval check in the initial model; configuring them on the provider, including adding file mounts or outbound network allow-list entries, is itself the approval for those capabilities. + +This is intentionally conservative and matches the shape of the current function-tool approval flow, where `FunctionTool` uses `always_require` / `never_require` and the auto-invocation loop escalates the whole batch if any called tool requires approval. + +If one sensitive provider-owned tool causes `execute_code` to require approval more often than desired, the mitigation is to keep that tool direct-only or expose it through a different CodeAct provider/tool surface. The initial model does not try to infer whether generated code will actually call that tool before approval. + +If the framework later standardizes pre-execution inspection or nested per-tool approvals, the Python provider surface can grow to expose that explicitly. The initial design does not assume that those extra modes are required. + +#### Shared execution flow + +On each run: +1. Resolve the provider's backend/runtime behavior, capabilities, provider default `approval_mode`, and provider-owned tool registry. +2. Compute the effective approval requirement for `execute_code` from the provider default plus the provider-owned tool registry snapshot. +3. Build provider-defined instructions. +4. Add `execute_code` to the model-facing tool surface. +5. Invoke the underlying model. +6. When `execute_code` is called, create or reuse an execution environment keyed by provider type, backend setup identity, capability configuration, and provider-owned tool signature. +7. If the current provider mode exposes host tools, expose `call_tool(...)` bound only to the provider-owned tool registry. +8. Execute code and convert results to framework-native content objects. + +Caching rules: +- Backends that support snapshots may cache a reusable clean snapshot. +- Backends that do not support snapshots may still cache warm initialization artifacts. +- No mutable per-run execution state may be shared across concurrent runs. +- In-memory interpreter state does not persist across separate `execute_code` calls. +- Configured workspace files, mounted files, and any writable artifact/output area are the supported persistence mechanism across calls when the backend exposes them. + +### Python public API + +#### Core types + +```python +class FileMount(NamedTuple): + host_path: str | Path + mount_path: str + +FileMountInput = str | tuple[str | Path, str] | FileMount + + +class AllowedDomain(NamedTuple): + target: str + methods: tuple[str, ...] | None = None + + +AllowedDomainInput = str | tuple[str, str | Sequence[str]] | AllowedDomain + + +class HyperlightCodeActProvider(ContextProvider): + def __init__( + self, + source_id: str = "hyperlight_codeact", + *, + backend: str = "wasm", + module: str | None = "python_guest.path", + module_path: str | None = None, + tools: ToolTypes | None = None, + approval_mode: Literal["always_require", "never_require"] = "never_require", + workspace_root: Path | None = None, + file_mounts: Sequence[FileMountInput] = (), + allowed_domains: Sequence[AllowedDomainInput] = (), + ) -> None: ... + + def add_tools(self, tools: ToolTypes | Sequence[ToolTypes]) -> None: ... + def get_tools(self) -> Sequence[ToolTypes]: ... + def remove_tool(self, name: str) -> None: ... + def clear_tools(self) -> None: ... + def add_file_mounts(self, mounts: FileMountInput | Sequence[FileMountInput]) -> None: ... + def get_file_mounts(self) -> Sequence[FileMount]: ... + def remove_file_mount(self, mount_path: str) -> None: ... + def clear_file_mounts(self) -> None: ... + def add_allowed_domains(self, domains: AllowedDomainInput | Sequence[AllowedDomainInput]) -> None: ... + def get_allowed_domains(self) -> Sequence[AllowedDomain]: ... + def remove_allowed_domain(self, domain: str) -> None: ... + def clear_allowed_domains(self) -> None: ... +``` + +`file_mounts` accepts three equivalent input forms: +- `"data/report.csv"` uses the same relative path on the host and in the sandbox. +- `("fixtures/users.json", "data/users.json")` or `(Path("fixtures/users.json"), "data/users.json")` uses distinct host and sandbox paths. +- `FileMount(Path("fixtures/users.json"), "data/users.json")` is the named-tuple form of the explicit pair. + +`allowed_domains` accepts three equivalent input forms: +- `"github.com"` allows that target with all backend-supported methods. +- `("github.com", "GET")` or `("github.com", ["GET", "HEAD"])` uses an explicit per-target method list. +- `AllowedDomain("github.com", ("GET", "HEAD"))` is the named-tuple form of the explicit entry. + +No public abstract `CodeActContextProvider` base or public `executor=` parameter is required for the initial Python API. + +The initial alpha package also exports a standalone `HyperlightExecuteCodeTool` +for direct-tool scenarios where a provider is not needed. That standalone tool +should advertise `call_tool(...)`, the registered sandbox tools, and capability +state through its own `description` rather than requiring separate agent +instructions. + +Provider modes: +- If no CodeAct-managed tools are configured, `HyperlightCodeActProvider` uses interpreter-style behavior. +- If one or more CodeAct-managed tools are configured, `HyperlightCodeActProvider` uses tool-enabled behavior. + +#### Python provider implementation contract + +The concrete provider plugs into the existing Python `ContextProvider` surface from `agent_framework._sessions`. + +The Hyperlight package also depends on a small set of core hooks that must remain available from `agent-framework-core`: +- `ContextProvider.before_run(...)` +- `SessionContext.extend_instructions(...)` +- `SessionContext.extend_tools(...)` +- per-run runtime tool access via `SessionContext.options["tools"]` +- the shared `ApprovalMode` vocabulary used by `FunctionTool` + +Required lifecycle hook: +- `before_run(*, agent, session, context, state) -> None` + +Optional lifecycle hook: +- `after_run(*, agent, session, context, state) -> None` + +`before_run(...)` is responsible for: +- snapshotting the current CodeAct-managed tool registry and capability settings for the run, +- computing the effective approval requirement for `execute_code` from the provider default and the snapshotted tool registry, +- adding a short CodeAct guidance block, +- adding `execute_code` to the run through `SessionContext.extend_tools(...)`, +- and wiring any backend-specific execution state needed for the run. + +These steps run on every invocation rather than once at construction time because the provider supports CRUD mutations between runs, concurrent runs need independent snapshots, and the effective approval and instructions depend on the tool registry state captured at run start. When the tool registry and capability configuration are fixed for the lifetime of the agent, the manual wiring pattern (see `codeact_manual_wiring.py`) can be used instead, which passes the tool and instructions directly to the `Agent` constructor and avoids the per-run provider lifecycle entirely. + +If the provider stores anything in `state`, that value must stay JSON-serializable. + +Mutating the provider after `before_run(...)` has captured a run-scoped snapshot is allowed, but it affects subsequent runs only. Provider implementations should synchronize state capture and CRUD operations so shared provider instances remain safe across concurrent runs. + +`after_run(...)` is responsible for any backend-specific cleanup or post-processing that must happen after the model invocation completes. + +If shared internal helpers are introduced later for multiple concrete providers, they should standardize responsibilities for: +- building instructions, +- computing effective approval, +- configuring file access, +- configuring network access, +- preparing or restoring execution state, +- executing code, +- and converting backend output into framework-native `Content`. + +#### Runtime behavior + +- `before_run(...)` adds a short CodeAct guidance block through `SessionContext.extend_instructions(...)`. +- `before_run(...)` adds `execute_code` through `SessionContext.extend_tools(...)`. +- The detailed `call_tool(...)`, sandbox-tool, and capability guidance is carried by `execute_code.description`. +- `execute_code` invokes the configured Hyperlight sandbox guest. +- If the current CodeAct tool registry is non-empty, the runtime injects `call_tool(...)` bound to the provider-owned tool registry. +- The provider does not inspect or mutate `Agent.default_options["tools"]` or `context.options["tools"]` to determine its CodeAct tool set. +- The provider snapshots the current CodeAct tool registry and capability state at run start, so later registry and allow-list mutations only affect future runs. +- Interpreter versus tool-enabled behavior is derived from the concrete provider and the presence of CodeAct-managed tools, not from a separate public profile object. +- `execute_code` should be traced like a normal tool invocation within the surrounding agent run, and provider-owned tool calls executed through `call_tool(...)` should continue to emit ordinary tool invocation telemetry. + +#### Backend integration + +Initial public provider: +- `HyperlightCodeActProvider` + +Backend-specific notes: +- **Hyperlight** + - Provider construction needs a guest artifact via `module`, which may be a packaged guest module name or a path to a compiled guest artifact. + - File access maps naturally to Hyperlight Sandbox's read-only `/input` and writable `/output` capability model. + - Network access is denied by default and is enabled through per-target allow-list entries. +- **Monty** + - A future `MontyCodeActProvider` should be a separate public type rather than a `HyperlightCodeActProvider` mode. + - Monty does not expose built-in filesystem or network access directly inside the interpreter. + - File and URL access are mediated through host-provided external functions, so a Monty provider would need to translate provider settings into virtual files and allow-checked callbacks. + - Monty setup may also include backend-specific inputs such as `script_name`, optional type-check stubs, or restored snapshots. + +#### Capability handling + +Capabilities are first-class `HyperlightCodeActProvider` init parameters and provider-managed CRUD surfaces: +- `workspace_root` +- `file_mounts` +- `allowed_domains` + +Concrete providers should normalize these settings internally. Hyperlight can map them directly to sandbox capabilities, while Monty must enforce them through host-mediated file and network functions and may apply stricter URL-level checks than the public provider surface expresses. + +Expected management split: +- `workspace_root` remains a direct configuration value on the provider, +- file mounts are managed through provider CRUD methods, +- outbound allow-list entries are managed through provider CRUD methods. + +Enabling access means: +- Configuring `workspace_root` or any `file_mounts` enables the sandbox filesystem surface exposed through `/input` and `/output`. +- Leaving both `workspace_root` and `file_mounts` unset means no filesystem surface is configured. +- Adding any `allowed_domains` entry enables outbound access only for the configured targets; leaving it empty means network access is disabled without a separate `network_mode` flag. +- A string target allows all backend-supported methods for that target; an explicit tuple or `AllowedDomain` entry narrows the methods for that target. + +Backends may implement stricter semantics than these top-level settings. For example, Hyperlight naturally maps file access to `/input` and `/output`, while Monty would enforce equivalent policy through host-provided callbacks rather than direct interpreter I/O. + +#### Execution output representation + +Backend execution output should be translated into existing AF `Content` values rather than a custom `CodeActExecutionResult` type. + +Use the existing content model from `agent_framework._types`, for example: +- `Content.from_code_interpreter_tool_result(outputs=[...])` to surface the overall result of sandboxed code execution, +- `Content.from_text(...)` for plain textual output, +- `Content.from_data(...)` or `Content.from_uri(...)` for generated files or binary artifacts, +- `Content.from_error(...)` for execution failures, +- and `Content.from_function_result(..., result=list[Content])` when surfacing the final result of `execute_code` through the normal tool result path. + +#### `execute_code` input contract + +```json +{ + "type": "object", + "properties": { + "code": { + "type": "string", + "description": "Code to execute using the provider's configured backend/runtime behavior." + } + }, + "required": ["code"] +} +``` + +Execution failures should surface readable error text and structured error `Content`, not a custom backend result object. + +Timeouts, out-of-memory conditions, backend crashes, and similar sandbox failures are all `execute_code` failures and should surface as structured error content.

This causes potential issues around checkpointing and making sure that we properly compute only the new incoming messages for each agent invocation. * fix: AgentSession checkpointing using AIAgent's Serialize/Deserialize methods We cannot rely on implicit serialization through `HandoffHostState` because we are missing type information. * fix: Thread safety issue in `MultiPartyConversation.AllMessages` * fix: Enable unwrapping of FunctionResultContent when ExternalRequest was wrapped into FunctionCallContent --- .../AIAgentsAbstractionsExtensions.cs | 2 +- .../Specialized/HandoffAgentExecutor.cs | 363 ++++++++---------- .../Specialized/HandoffEndExecutor.cs | 33 +- .../Specialized/HandoffMessagesFilter.cs | 143 +++++++ .../Specialized/HandoffStartExecutor.cs | 49 ++- .../Specialized/HandoffState.cs | 4 - .../Specialized/MultiPartyConversation.cs | 56 +++ .../WorkflowHostingExtensions.cs | 2 +- .../WorkflowSession.cs | 37 +- .../HandoffAgentExecutorTests.cs | 244 +++++++++--- .../Sample/12_HandOff_HostAsAgent.cs | 1 + .../SampleSmokeTest.cs | 81 +++- .../TestRunContext.cs | 12 +- 13 files changed, 710 insertions(+), 317 deletions(-) create mode 100644 dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffMessagesFilter.cs create mode 100644 dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/MultiPartyConversation.cs diff --git a/dotnet/src/Microsoft.Agents.AI.Workflows/AIAgentsAbstractionsExtensions.cs b/dotnet/src/Microsoft.Agents.AI.Workflows/AIAgentsAbstractionsExtensions.cs index 165de39855..8c94f4aa85 100644 --- a/dotnet/src/Microsoft.Agents.AI.Workflows/AIAgentsAbstractionsExtensions.cs +++ b/dotnet/src/Microsoft.Agents.AI.Workflows/AIAgentsAbstractionsExtensions.cs @@ -48,7 +48,7 @@ internal static class AIAgentsAbstractionsExtensions /// any that have a different from to /// . /// - public static List?

Add a guard to only start a new conversation when there is no existing service_session_id, matching the pattern used by other agents.

Use the plural TargetFrameworks property set to net10.0 only to properly override it, and remove the now-unnecessary net472 condition on ItemGroup. * fixes aspire config * fix: update Microsoft.Extensions packages to version 10.0.1 * Address Copilot review feedback on DevUI Aspire integration - Fix request body dropping in ProxyConversationsAsync: always read the body when ContentLength > 0 before routing, then pass it through to all proxy calls (previously null was passed when backend was resolved from query param or conversation map) - Fix resource leak: dispose aggregator on startup failure in catch block - Fix XML docs: accurately describe embedded resource serving behavior - Remove reflection from DevUIResourceTests (InternalsVisibleTo already set) - Make sensitive telemetry conditional on Development environment in samples Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: update chat client version to gpt41 in both

The aggregator is a lightweight Kestrel server that: + +1. **Serves the DevUI frontend** from the `Microsoft.Agents.AI.DevUI` assembly's embedded resources (loaded at runtime). If the assembly is not available, it falls back to proxying the frontend from the first backend. +2. **Aggregates entities** from all configured agent service backends into a single `/v1/entities` listing. Each entity ID is prefixed with the backend name to ensure uniqueness across services (e.g., `writer-agent/writer`, `editor-agent/editor`). +3. **Routes requests** to the correct backend based on the entity ID prefix. When DevUI sends a `POST /v1/responses` or `/v1/conversations` request, the aggregator strips the prefix and forwards it to the appropriate service. +4. **Streams SSE responses** for the `/v1/responses` endpoint, so agent responses stream back to the DevUI frontend in real time. + +The aggregator publishes its URL to the Aspire dashboard, where it appears as a clickable link. + +## Agent discovery + +By default, `WithAgentService` declares a single agent named after the Aspire resource. You can provide explicit agent metadata when the agent name differs from the resource name, or when a service hosts multiple agents: + +```csharp +builder.AddDevUI("devui") + .WithAgentService(writerAgent, agents: [new("writer", "Writes short stories")]) + .WithAgentService(editorAgent, agents: [new("editor", "Edits and formats stories")]); +``` + +Agent metadata is declared at the AppHost level so the aggregator builds the entity listing directly — agent services don't need a `/v1/entities` endpoint. + +## Configuration + +### Custom entity ID prefix + +By default, entity IDs are prefixed with the Aspire resource name. You can specify a custom prefix: + +```csharp +builder.AddDevUI("devui") + .WithAgentService(myService, entityIdPrefix: "custom-prefix"); +``` + +### Custom port + +You can specify a fixed host port for the DevUI web interface: + +```csharp +builder.AddDevUI("devui", port: 8090); +``` + +### DevUI frontend assembly + +To serve the DevUI frontend directly from the aggregator (instead of proxying from a backend), add the `Microsoft.Agents.AI.DevUI` NuGet package to your AppHost project.

Ships with unit tests, a sample, and a design doc. azure-ai-projects is pinned to the public >=2.0.0,<3.0 range and the lockfile resolves from public PyPI. The toolbox test module skips when Toolbox* types are unavailable so CI stays green until the public 2.1.0 SDK lands.

Toolbox fetching requires the project client, so these new methods must be instance methods. This is a deliberate departure from the existing-factory pattern, justified by the async-with-I/O nature of the operation. + +**Raw SDK type passthrough (no custom wrappers).** There is only one toolbox type in the Foundry SDK and maintaining a shadow wrapper would create alignment risk as the SDK evolves. The raw `ToolboxVersionObject` and `ToolboxObject` carry all the fields users need. Individual tools inside `toolbox.tools` are the same `azure.ai.projects.models.Tool` subclasses returned by other factory methods. + +**Two-request default-version path.** When `version=None`, implementation calls `.get(name)` to find `default_version`, then `.get_version(name, default_version)` for the tools. Caching the default-version mapping was considered and rejected — default versions can change server-side via `update(default_version=...)`, and a stale cache would silently give callers the wrong tools. Two requests at agent setup is acceptable. + +**No discovery/listing surface in MAF.** Discovery is intentionally left to the raw `azure-ai-projects` client. MAF does not currently expose project-resource listing surfaces for many other Foundry resources (deployments, vector stores, agents, etc.), so the toolbox design stays narrowly focused on explicit retrieval by name/version. + +**Shared helpers in `_tools.py`.** The SDK-call helper function (`fetch_toolbox`) lives in a shared module so the chat-client surface stays thin and the request logic remains centralized. + +**`tools=toolbox` convenience, not a new wrapper type.** Although `get_toolbox()` returns the raw `ToolboxVersionObject`, Agent Framework can still support `tools=toolbox` / `tools=[toolbox]` by flattening the toolbox's `.tools` internally. That matches existing SDK ergonomics where some higher-level objects can be placed directly in `tools=` and unpacked underneath, without introducing a public `FoundryToolbox` wrapper. + +**Errors pass through unchanged.** `ResourceNotFoundError`, `HttpResponseError`, etc. from the SDK propagate as-is.

This design is specifically for `FoundryChatClient`-backed local agent composition. + +2. **MCP consumption (already supported through existing MCP abstractions).** A Foundry toolbox can also be exposed as an MCP server. In that case, use the existing `MCPStreamableHTTPTool(name=..., url=...)` — it already handles this path with any chat client (Foundry, OpenAI, Anthropic, etc.). No new Foundry-specific API is needed for MCP-exposed toolboxes in this design. + +### MCPStreamableHTTPTool example for a Foundry toolbox endpoint + +If Foundry gives you an MCP endpoint for the toolbox (for example from the +toolbox details UI / endpoint surface), the existing MCP client path is: + +```python +from agent_framework import Agent, MCPStreamableHTTPTool +from agent_framework.openai import OpenAIChatClient + +toolbox_mcp = MCPStreamableHTTPTool( + name="research_tools", + url="https://", +) + +agent = Agent( + client=OpenAIChatClient(), + instructions="You are a research assistant.", + tools=[toolbox_mcp], +) +``` + +This is a different integration shape than `get_toolbox(...).tools`: + +- `get_toolbox(...).tools` = **native Foundry hosted-tool configs** interpreted by the + Foundry runtime +- `MCPStreamableHTTPTool(name=..., url=...)` = **live MCP server connection** to a + toolbox endpoint + +The design in this spec adds first-class support only for the native hosted-tool +path.

Native toolbox tools are declarative configs the Foundry runtime executes; MCP consumption is a live wire protocol to a running server. + +**MCP authentication inside a toolbox** is handled server-side via `project_connection_id` on individual `MCPTool` entries (OAuth connection objects configured in the Foundry project). The client never holds bearer tokens.

18/30] Python: Foundry hosted agent V2 (#5379) * Python: Wrapper + Samples 1st (#5177) * Experiment * Update dependency and add non streaming * Add more samples * Rename samples * Add invocations * Comments 1 * Comments 2 * Comments 3 * Improve README * Add local shell sample * WIP: Add eval and memory samples * Update user agent prefix * Update user agent prefix doc * Update dependency (#5215) * Add tests and more content types (#5235) * Add tests * fix tests and sample * Fix formatting * Remove function approval contents * Python: Refine samples and upgrade packages (#5261) * Refine samples and upgrade pacakges * Upgrade to a new package that fixes a bug * Update model env var * Move samples (#5281) * Python: Upgrade agentserver packages (#5284) * Upgrade agentserver packages * Fix new types * Python: Add special handling for workflows (#5298) * Add special handling for workflows * Address comments * Improve samples (#5372) * Python: Add more types (#5378) * Add more type supports * Upgrade packages * Remove TODOs in README * Fix README * Comments and mypy * User agent scoped * Fix README * Fix pre commit * Fix pre commit 2 * Fix pre commit 3 * Fix pre commit 4 * Fix pre commit 5 * Fix pre commit 6 * Add azure-monitor-opentelemetry to dev deps Fixes Samples & Markdown CI failure. The PR's new transitive dep on azure-monitor-opentelemetry-exporter (via azure-ai-agentserver-core) makes pyright resolve the azure.monitor.opentelemetry namespace, flipping the check_md_code_blocks diagnostic for `configure_azure_monitor` from reportMissingImports (filtered) to reportAttributeAccessIssue (not filtered). Installing the umbrella azure-monitor-opentelemetry package in dev makes pyright resolve the symbol correctly, matching the install guidance the observability README already gives users. ---------

This demonstrates how code-based agents can execute custom server-side logic that prompt agents cannot access. - -The tool accepts: - -- **check_in_date** - Check-in date in YYYY-MM-DD format -- **check_out_date** -

The workflow operates as follows: - -1. **Writer Agent** - Drafts content -2. **Reviewer Agent** - Reviews the draft and provides concise, actionable feedback - -### Agent Hosting - -The agent workflow is hosted using the [Azure AI AgentServer SDK](https://pypi.org/project/azure-ai-agentserver-agentframework/), -which provisions a REST API endpoint compatible with the OpenAI Responses protocol. - -### Agent Deployment - -The hosted agent workflow can be deployed to Microsoft Foundry using the Azure Developer CLI [ai agent](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry&tabs=cli#create-a-hosted-agent) extension. - -## Running the Agent Locally - -### Prerequisites - -Before running this sample, ensure you have: - -1. **Microsoft Foundry Project** - - Project created in [Microsoft Foundry](https://learn.microsoft.com/en-us/azure/ai-foundry/what-is-foundry?view=foundry#microsoft-foundry-portals) - - Chat model deployed (e.g., `gpt-4o` or `gpt-4.1`) - - Note your project endpoint URL and model deployment name - -2. **Azure CLI** - - Installed and authenticated - - Run `az login` and verify with `az account show` - -3. **Python 3.10 or higher** - - Verify your version: `python --version` - -### Environment Variables - -Set the following environment variables (matching `agent.yaml`): - -- `FOUNDRY_PROJECT_ENDPOINT` - Your Microsoft Foundry project endpoint URL (required) -- `FOUNDRY_MODEL` - The deployment name for your chat model (defaults to `gpt-4.1-mini`) - -This sample loads environment variables from a local `.env` file if present. - -Create a `.env` file in this directory with the following content: - -``` -FOUNDRY_PROJECT_ENDPOINT=https://.services.ai.azure.com/api/projects/ -FOUNDRY_MODEL=gpt-4.1-mini -``` - -Or set them via PowerShell: - -```powershell -# Replace with your actual values -$env:FOUNDRY_PROJECT_ENDPOINT="https://.services.ai.azure.com/api/projects/" -$env:FOUNDRY_MODEL="gpt-4.1-mini" -``` - -### Running the Sample - -**Recommended (`uv`):** - -We recommend using [uv](https://docs.astral.sh/uv/) to create and manage the virtual environment for this sample. - -```bash -uv venv .venv -uv pip install --prerelease=allow -r requirements.txt -uv run main.py -``` - -The sample depends on preview packages, so `--prerelease=allow` is required when installing with `uv`. - -**Alternative (`venv`):** - -If you do not have `uv` installed, you can use Python's built-in `venv` module instead: - -**Windows (PowerShell):** - -```powershell -python -m venv .venv -.\.venv\Scripts\Activate.ps1 -pip install -r requirements.txt -python main.py -``` - -**macOS/Linux:** - -```bash -python -m venv .venv -source .venv/bin/activate -pip install -r requirements.txt -python main.py -``` - -This will start the hosted agent locally on `http://localhost:8088/`. - -### Interacting with the Agent - -**PowerShell (Windows):** - -```powershell -$body = @{ - input = "Create a slogan for a new electric SUV that is affordable and fun to drive." - stream = $false -} | ConvertTo-Json - -Invoke-RestMethod -Uri http://localhost:8088/responses -Method Post -Body $body -ContentType "application/json" -``` - -**Bash/curl (Linux/macOS):** - -```bash -curl -sS -H "Content-Type: application/json" -X POST http://localhost:8088/responses \ - -d '{"input": "Create a slogan for a new electric SUV that is affordable and fun to drive.","stream":false}' -``` - -### Deploying the Agent to Microsoft Foundry - -To deploy your agent to Microsoft Foundry, follow the comprehensive deployment guide at https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry&tabs=cli - -## Troubleshooting - -### Images built on Apple Silicon or other ARM64 machines do not work on our service - -We **recommend using `azd` cloud build**, which always builds images with the correct architecture. - -If you choose to **build locally**, and your machine is **not `linux/amd64`** (for example, an Apple Silicon Mac), the image will **not be compatible with our service**, causing runtime failures. - -**Fix for local builds** - -Use this command to build the image locally: - -```shell -docker build --platform=linux/amd64 -t image . -``` - -This forces the image to be built for the required `amd64` architecture. diff --git a/python/samples/05-end-to-end/hosted_agents/writer_reviewer_agents_in_workflow/agent.yaml b/python/samples/05-end-to-end/hosted_agents/writer_reviewer_agents_in_workflow/agent.yaml deleted file mode 100644 index 36e08b7e77..0000000000 --- a/python/samples/05-end-to-end/hosted_agents/writer_reviewer_agents_in_workflow/agent.yaml +++ /dev/null @@ -1,24 +0,0 @@ -# yaml-language-server: $schema=https://raw.githubusercontent.com/microsoft/AgentSchema/refs/heads/main/schemas/v1.0/ContainerAgent.yaml -

<35585003+moonbox3@users.noreply.github.com> Date: Tue, 21 Apr 2026 16:08:50 +0900 Subject: [PATCH 20/30] Python: Add second approval-required tool (set_stop_loss) to concurrent_builder_tool_approval sample (#4875) * Add set_stop_loss tool to concurrent_builder_tool_approval sample Add a second approval-gated tool (set_stop_loss) to the concurrent workflow tool approval sample to demonstrate handling approval requests for different tools in the same concurrent workflow. Changes: - Add set_stop_loss(symbol, stop_price) with approval_mode='always_require' - Include new tool in both agents' tool lists - Update agent instructions and prompt to encourage stop-loss usage - Update docstring to reflect two approval-gated tools - Update sample output to show mixed approval requests Fixes #4874 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Print tool name and arguments in concurrent sample's process_event_stream (#4874) Align process_event_stream in concurrent_builder_tool_approval.py to print the tool name and arguments when collecting approval requests, matching the sample output comment and the sequential_builder_tool_approval.py pattern. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add None-guard for function_call access in tool approval sample (#4874) Add explicit None-checks before accessing function_call.name and function_call.arguments in concurrent_builder_tool_approval.py. The function_call field is typed Content | None, so direct attribute access without a guard could raise AttributeError and required type: ignore comments. The None-guard is consistent with the pattern used in _agent_run.py and removes the suppression comments. Also add a regression test verifying that function_call defaults to None and that the None-guard pattern is safe. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Apply same function_call None-guard to sibling tool-approval samples (#4874) Apply the same fix to sequential_builder_tool_approval.py and group_chat_builder_tool_approval.py, which had the identical pattern of accessing function_call.name/arguments without a None-guard.

This can result in message lists containing multiple turn to fail to filter properly. The fix is to take advantage of the expectation that Handoff Orchestration is a "single-speaker" flow, which only has a single active AIAgent per "turn" and an agent's turn is not finished until all outstanding function calls are finished. This allows us to expect that any ambiguous-CallId FunctionCallContent are either in separate turns or will have had a response before the next issued call with the same Id. --- .../Specialized/HandoffAgentExecutor.cs | 4 +- .../Specialized/HandoffMessagesFilter.cs | 144 +++++++----------- .../HandoffMessageFilterTests.cs | 115 ++++++++++++++ 3 files changed, 172 insertions(+), 91 deletions(-) create mode 100644 dotnet/tests/Microsoft.Agents.AI.Workflows.UnitTests/HandoffMessageFilterTests.cs diff --git a/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs b/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs index d9acab96d5..576c749a90 100644 --- a/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs +++ b/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs @@ -426,7 +426,7 @@ internal sealed class HandoffAgentExecutor : { AgentId = this._agent.Id, AuthorName = this._agent.Name ?? this._agent.Id, - Contents = [new FunctionResultContent(handoffRequest.CallId, "Transferred.")], + Contents = [CreateHandoffResult(handoffRequest.CallId)], CreatedAt = DateTimeOffset.UtcNow, MessageId = Guid.NewGuid().ToString("N"), Role = ChatRole.Tool, @@ -459,4 +459,6 @@ internal sealed class HandoffAgentExecutor : ? this._handoffFunctionToAgentId.TryGetValue(requestedHandoff, out string? targetId) ? targetId : null : null; } + + internal static FunctionResultContent CreateHandoffResult(string requestCallId) => new(requestCallId, "Transferred."); } diff --git a/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffMessagesFilter.cs b/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffMessagesFilter.cs index 7bc178c2d4..61eebc0e2b 100644 --- a/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffMessagesFilter.cs +++ b/dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffMessagesFilter.cs @@ -3,7 +3,6 @@ using System; using System.Collections.Generic; using System.Diagnostics.CodeAnalysis; -using System.Linq; using Microsoft.Extensions.AI; namespace Microsoft.Agents.AI.Workflows.Specialized; @@ -31,113 +30,78 @@ internal sealed class HandoffMessagesFilter return messages; } - Dictionary filteringCandidates = new(); - List filteredMessages = []; - HashSet messagesToRemove = []; + HashSet filteredCallsWithoutResponses = new(); + List retainedMessages = []; + + bool filterAllToolCalls = this._filteringBehavior == HandoffToolCallFilteringBehavior.All; + + // The logic of filtering is fairly straightforward: We are only interested in FunctionCallContent and FunctionResponseContent. + // We are going to assume that Handoff operates as follows: + // * Each agent is only taking one turn at a time + // * Each agent is taking a turn alone + // + // In the case of certain providers, like Gemini (see microsoft/agent-framework #5244), we will see the function call name as the + // call id as well, so we may see multiple calls with the same call id, and assume that the call is terminated before another + // "CallId-less" FCC is issued.

The Azure SDK rewrites deployment-based endpoints (including /embeddings) by inserting /deployments/{model}/ into the URL, producing 404s on the OpenAI-compatible /openai/v1 endpoint. Use AsyncOpenAI instead of AsyncAzureOpenAI when the resolved base_url targets /openai/v1, converting the Azure token provider to an async api_key callable. The responses_mode path is unaffected because the Responses API (/responses) is not in the SDK's rewrite list.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add Invocations protocol samples (hosted echo agent + client) (#5278) Add Hosted-Invocations-EchoAgent: a minimal echo agent hosted via the Invocations protocol (POST /invocations) using AddInvocationsServer and MapInvocationsServer, bridged to an Agent Framework AIAgent through a custom InvocationHandler. Add SimpleInvocationsAgent: a console REPL client that wraps HttpClient calls to the /invocations endpoint in a custom InvocationsAIAgent, demonstrating programmatic consumption of the Invocations protocol. Both samples default to port 8088 for consistency with other hosted agent samples. * Restructure FoundryHostedAgents samples into invocations/ and responses/ Align dotnet hosted agent samples with the Python side (PR #5281) by reorganizing the directory structure: - Remove HostedAgentsV1 entirely (old API pattern) - Split HostedAgentsV2 into invocations/ and responses/ based on protocol - Move Using-Samples accordingly (SimpleAgent to responses, SimpleInvocationsAgent to invocations) - Update slnx with new project paths and add previously missing invocations projects - Update README cd paths from HostedAgentsV2 to invocations or responses - Rename .env.local to .env.example to match Python naming convention - Fix format violations in newly included invocations projects * Remove launchSettings, use .env for port configuration - Delete all launchSettings.json files (port 8088 now comes from ASPNETCORE_URLS in .env) - Add DotNetEnv to Hosted-Invocations-EchoAgent so it loads .env like the responses samples - Create .env.example for EchoAgent with ASPNETCORE_URLS and ASPNETCORE_ENVIRONMENT - Add AGENT_NAME to ChatClientAgent and FoundryAgent .env.example (required by those samples) - Add AZURE_BEARER_TOKEN=DefaultAzureCredential to all .env.example files - Update DevTemporaryTokenCredential in all 6 samples to treat the sentinel value as unavailable, allowing ChainedTokenCredential to fall through to DefaultAzureCredential - Update EchoAgent README with Configuration section * Use placeholder for AGENT_NAME in Hosted-FoundryAgent .env.example * Move FoundryResponsesHosting to responses/Hosted-WorkflowHandoff, use GetResponsesClient * Rename Hosted-Workflows to Hosted-Workflow-Simple, Hosted-WorkflowHandoff to Hosted-Workflow-Handoff * Remove FoundryResponsesRepl and empty FoundryResponsesHosting directory * Add Dockerfiles, README, agent yamls and bearer token support to Hosted-Workflow-Handoff - Add Dockerfile and Dockerfile.contributor for Docker-based testing - Add agent.yaml and agent.manifest.yaml with triage-workflow as primary agent - Add README.md following sibling pattern, noting Azure OpenAI vs Foundry endpoint - Add DevTemporaryTokenCredential and ChainedTokenCredential for Docker auth - Register triage-workflow as non-keyed default so azd invoke works without model - Update .env.example with AZURE_BEARER_TOKEN sentinel - Add .gitignore to 04-hosting to suppress VS-generated launchSettings.json - Fix docker run image name in Hosted-Workflow-Simple README * Fix AgentFrameworkResponseHandlerTests: implement session methods in test mock agents * .NET: Auto-instrument resolved AIAgents with OpenTelemetry for Foundry Hosted Agents (#5316) * Auto-instrument resolved AIAgents with OpenTelemetry using Core ResponsesSourceName * Add OTel telemetry capture tests for Foundry hosted agent handler * Net: Prepare Foundry Preview Release (#5336) * Prepare Foundry preview release 1.2.0-preview.* Bump VersionPrefix to 1.2.0 and update the preview stamp date. Invert packaging opt-in so only the Foundry preview set produces NuGet packages: - Microsoft.Agents.AI.Abstractions - Microsoft.Agents.AI - Microsoft.Agents.AI.Workflows - Microsoft.Agents.AI.Workflows.Generators - Microsoft.Agents.AI.Foundry Flip IsReleased=false on the preview set so they pick up the -preview.YYMMDD.N suffix. Gate GeneratePackageOnBuild on IsPackable=true. Remove the global IsPackable=true from nuget-package.props so the repo-level default (false) applies to everything else. * Lower preview VersionPrefix to 0.0.1 Retroactive preview publish: bump VersionPrefix and GitTag from 1.2.0 to 0.0.1 so the 5 Foundry preview packages emit as 0.0.1-preview.260417.1. * Net: Publish all packages as 0.0.1-preview.260417.2 (#5341) Revises the Foundry pre-release approach to publish ALL normally packable src projects as preview packages stamped 0.0.1-preview.260417.2, including projects previously flagged IsReleased=true or with a non-default VersionSuffix (rc/alpha). nuget-package.props: - Collapse the four conditional PackageVersion expressions (IsReleaseCandidate, VersionSuffix, default preview, IsReleased stable) into a single unconditional 0.0.1-preview.260417.2. On this preview-only branch every package ships with the same pre-release stamp regardless of per-project flags. - Restore the global IsPackable=true default (offsetting the repo-wide IsPackable=false in Directory.Build.props). Projects that opt out (Mem0, Declarative) already set IsPackable=false AFTER importing this file so they remain non-packable. - Remove the IsReleased-gated EnablePackageValidation line. Package validation does not apply to a 0.0.1 preview. csproj reverts (Abstractions, Agents.AI, Workflows, Workflows.Generators, Foundry): - Revert the IsPackable=true opt-in block introduced in #5336 (now redundant since the props default is true again). - Restore IsReleased=true to its pre-PR value. The setting is now a no-op because the props no longer branches on it. * Bump preview version to 260420.1 and fix AgentServer package deps (#5367) - Bump PackageVersion to 0.0.1-preview.260420.1 - Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by Azure.AI.AgentServer.Responses beta.3) - Replace AgentHostTelemetry.ResponsesSourceName with local constant (type made internal in AgentServer.Core beta.22) Co-authored-by: alliscode Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Hosted agents toolbox support (#5368) * feat: Add Foundry Toolbox (MCP) support to AgentFrameworkResponseHandler Adds support for Foundry Toolsets MCP proxy integration in the hosted agent response handler. Toolsets connect at startup via IHostedService, gating the readiness probe per spec §3.1. MCP tools are injected into every request's ChatOptions and OAuth consent errors (-32006) are intercepted and surfaced as mcp_approval_request + incomplete SSE events. New files: - FoundryToolboxOptions.cs: configuration POCO for toolset names and API version - FoundryToolboxBearerTokenHandler.cs: DelegatingHandler with Azure Bearer token auth, Foundry-Features header injection, and 3x exponential backoff on 429/5xx - McpConsentContext.cs: AsyncLocal-based per-request consent state shared between the tool wrapper and the response handler - ConsentAwareMcpClientTool.cs: AIFunction wrapper that catches -32006 errors and signals consent via shared state and linked CancellationTokenSource - FoundryToolboxService.cs: IHostedService that creates McpClient per toolset at startup and exposes cached tools Modified files: - AgentFrameworkResponseHandler.cs: injects toolbox tools into ChatOptions, sets up linked CTS consent interception, emits mcp_approval_request on -32006 - ServiceCollectionExtensions.cs: adds AddFoundryToolboxes(params string[]) extension - Microsoft.Agents.AI.Foundry.csproj: adds ModelContextProtocol and Azure.Identity dependencies under NETCoreApp condition Sample: - Hosted-Toolbox: minimal hosted agent sample using AddFoundryToolboxes * Rename toolset to toolbox in user-facing API; rename ConsentAwareMcpClientTool to ConsentAwareMcpClientAIFunction * Add HostedMcpToolboxAITool for client-selectable Foundry toolboxes Introduces HostedMcpToolboxAITool, a marker tool subclassing HostedMcpServerTool that rides the OpenAI Responses 'mcp' wire format to let clients request a specific Foundry toolbox per request. - New FoundryAITool.CreateHostedMcpToolbox(name, version?) factory. - FoundryToolboxOptions.StrictMode (default true) rejects unregistered toolboxes; set to false to allow lazy-open on first use. - FoundryToolboxService.GetToolboxToolsAsync(name, version?) resolves cached or lazy-opened MCP tools. - AgentFrameworkResponseHandler parses request.Tools for foundry-toolbox://name[?version=v] markers and injects resolved tools per request, merging with pre-registered ones. - Unit tests for marker parsing and strict-mode resolution. * Bump Azure.AI.Projects to 2.1.0-alpha; add ToolboxRecord/ToolboxVersion factory overloads + tests * Fix PR review issues: retry off-by-one, URI encoding, docs, tests, build - Fix off-by-one in FoundryToolboxBearerTokenHandler retry loop (4 attempts → 3) - URI-encode version parameter in HostedMcpToolboxAITool.BuildAddress - Add XML doc clarifying version pinning is reserved for future use - Add comment clarifying AddHostedService deduplication safety - Fix DevTemporaryTokenCredential expiry to use DateTimeOffset.MaxValue - Fix AgentCard ambiguity in A2AServer sample with using alias - Add 18 new unit tests for retry handler and ReadMcpToolboxMarkers Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Roger Barreto <19890735+rogerbarreto@users.noreply.github.com> Co-authored-by: alliscode Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Hosted agent adapter (#5371) * Bump preview version to 260420.1 and fix AgentServer package deps - Bump PackageVersion to 0.0.1-preview.260420.1 - Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by Azure.AI.AgentServer.Responses beta.3) - Replace AgentHostTelemetry.ResponsesSourceName with local constant (type made internal in AgentServer.Core beta.22) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix CA1873: guard LogError with IsEnabled check in FoundryToolboxService Wrap the LogError call with an IsEnabled(LogLevel.Error) guard to satisfy the CA1873 analyzer rule which flags potentially expensive argument evaluation when logging is disabled.

This resolves NU5104 build errors caused by the stable Foundry package depending on prerelease Azure SDK packages (Azure.AI.AgentServer.Responses, Azure.AI.Projects beta). Changes: - Create Microsoft.Agents.AI.Foundry.Hosting with VersionSuffix=preview, targeting .NET Core only (net8.0/9.0/10.0) - Move all Hosting/ source files to the new project - Move ToolboxRecord/ToolboxVersion overloads to FoundryAIToolExtensions - Revert Azure.AI.Projects to 2.0.0 in Directory.Packages.props; Hosting uses VersionOverride for 2.1.0-beta.1 - Clean V1 Foundry csproj: remove beta deps, ASP.NET Core ref, hosting conditionals - Update 8 hosted agent sample projects to reference Foundry.Hosting - Split unit tests: ToolboxRecord/ToolboxVersion tests moved to Hosting/ - Add Foundry.Hosting to solution file Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review comments: experimental attrs, doc fixes, token propagation - Add [Experimental(OPENAI001)] to all 7 public Hosting types per reviewer request - Fix McpConsentContext XML doc: 'Thread-static' -> 'Async-local' (AsyncLocal flows with ExecutionContext, not thread-static) - Expand UserAgentMiddleware test regex to match prerelease versions (e.g. 1.0.0-rc.4) - Propagate CancellationToken in AgentFrameworkResponseHandler session save Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove unnecessary MEAI001 suppression from stable Foundry package MEAI001 was a leftover from when Hosting code lived in the same project. The stable V1 Foundry package builds clean without it, and suppressing experimental diagnostics in a released package can hide unintentional exposure of experimental APIs to consumers.

🚀 Foundry Responses Hosting

+

+ Agent-framework agents hosted via the Azure AI Responses Server SDK.
+ Each demo registers a different agent and serves it through POST /responses. +

+
+ +

🔧 Tool Demo

+

An agent with local function tools (time, weather) and remote MCP tools from + Microsoft Learn for documentation search.

+
+ Local Tools + MCP + Microsoft Learn + Streaming +
