* Move token params from HarnessAgent constructor to options
Remove the required maxContextWindowTokens and maxOutputTokens
constructor parameters from HarnessAgent and AsHarnessAgent, replacing
them with optional MaxContextWindowTokens and MaxOutputTokens properties
on HarnessAgentOptions.
When both values are provided, compaction is enabled as before (in-loop
CompactionProvider and chat reducer on the default InMemoryChatHistory
Provider). When either is null, compaction is disabled entirely, making
it opt-in.
New constructor: HarnessAgent(IChatClient, HarnessAgentOptions?,
ILoggerFactory?, IServiceProvider?)

* Improving comments.
* feat: Add custom CompactionStrategy and DisableCompaction to HarnessAgentOptions
Allow users to provide their own CompactionStrategy via options, with
a clear priority system:
1. DisableCompaction=true: no compaction regardless of other settings
2. Custom CompactionStrategy provided: use it (token params ignored)
3. Both MaxContextWindowTokens and MaxOutputTokens set: default strategy
4. Otherwise: no compaction

* Promote Workflows.Declarative packages to stable versions
* Address PR feedback: enable package validation on GA declarative packages
Both Workflows.Declarative and Workflows.Declarative.Mcp set IsReleased=true
but were disabling package validation, bypassing the repo's GA convention
(see dotnet/nuget/nuget-package.props which auto-enables validation when
IsReleased=true).
Re-enable validation by removing the local EnablePackageValidation=false
overrides and pointing PackageValidationBaselineVersion at 1.8.0-rc1 (the
latest published version of each package). This catches accidental breaking
changes between RC and the first GA. Future GAs should bump the baseline to
the previous GA version.
Verified locally: dotnet build -c Release on both projects runs
RunPackageValidation -> APICompat ran successfully without finding any
breaking changes.

* Fix missing id on function_call_output in Foundry Hosting
The Foundry storage layer was rejecting responses with
"ID cannot be null or empty (Parameter 'id')" because
function_call_output items emitted by OutputConverter had no id on
the wire.
OutputItemFunctionToolCallOutput's public ctor only sets CallId and
Output; Id is read-only and only the SDK's internal ctor populates
it. OutputItemBuilder<T>.ApplyAutoStamps fills ResponseId and
AgentReference but not Id, so the itemId passed to
AddOutputItem<T>(itemId) was used only for event sequencing and the
serialized item went out with id=null.
Switch to stream.OutputItemFunctionCallOutput(callId, output), the
SDK convenience method that uses the internal ctor and stamps the
id. Add a regression test asserting the added/done events carry a
non-empty matching Id.

* ci: free disk space and relocate NuGet cache on ubuntu runners
The ubuntu-latest dotnet-build/test jobs were hitting No space left on device because the runner image only ships ~14 GB free on /. The full multi-TFM build plus the dotnet pack + console-app install-check exhausts that easily.
Add a reusable composite action .github/actions/free-runner-disk-space that runs on Linux runners only and:
* removes pre-installed toolchains we never use here (Android SDK, GHC/Haskell, CodeQL, PyPy, Ruby, Go, boost, vcpkg, etc.), prunes docker images, and disables swap (reclaims ~25-30 GB on /)
* relocates the NuGet package cache to /mnt/nuget via NUGET_PACKAGES env, since /mnt has ~75 GB free on hosted runners
Wire the action into the four ubuntu-touching jobs in dotnet-build-and-test.yml (dotnet-build, dotnet-test, dotnet-foundry-hosted-it, dotnet-test-functions). The action self-guards with runner.os == 'Linux' so the matrix legs that run on windows are unaffected.

* Bump Azure.AI.AgentServer.* package versions
* Align Azure.Core/System.ClientModel to AgentServer transitive deps
Bump Azure.Core 1.55->1.56 and System.ClientModel 1.11->1.12 to match Azure.AI.AgentServer.* requirements, and add explicit references in transitive-pinning-off Foundry consumers to avoid CS1705/MSB3277 version conflicts.
* test: reshuffle .NET Workflow tests in preparation for Outputs overhaul
Phase 1 of the .NET Workflows outputs overhaul (see
working/implementation-plan.md). Pure moves/renames in
dotnet/tests/Microsoft.Agents.AI.Workflows.UnitTests; no production code
changes, no new test cases. The split keeps each orchestration mode in
its own source file so the upcoming tag-aware and orchestration-default
test additions land on clean diffs.
Renames:
* WorkflowBuilderSmokeTests.cs -> WorkflowBuilderTests.cs (with class
rename to match). The scope is no longer "smoke"-only once subsequent
phases add tag-aware builder tests.
* InputWaiterAndOutputFilterTests.cs -> InputWaiterTests.cs +
OutputFilterTests.cs. The file already declared the two test classes
separately; this split simply gives each its own file so the
output-filter cases have a dedicated home for tag-aware additions.
Split of AgentWorkflowBuilderTests.cs:
* AgentWorkflowBuilderTests.cs is now the outer
`public static partial class AgentWorkflowBuilderTests` holding the
shared test helpers (DoubleEchoAgent + session + WithBarrier variant,
WorkflowRunResult, RunWorkflow* methods) bumped from `private` to
`internal` so the new top-level GroupChatWorkflowBuilderTests in the
same assembly can reach them.
* AgentWorkflowBuilder.SequentialTests.cs (nested SequentialTests):
BuildSequential_InvalidArguments_Throws,
BuildSequential_AgentsRunInOrderAsync.
* AgentWorkflowBuilder.ConcurrentTests.cs (nested ConcurrentTests):
BuildConcurrent_InvalidArguments_Throws,
BuildConcurrent_AgentsRunInParallelAsync.
Sequential and Concurrent are kept as nested classes because they're
modes of the same `AgentWorkflowBuilder` static factory and do not
produce dedicated builder types.
New file:
* GroupChatWorkflowBuilderTests.cs (top-level): the existing
BuildGroupChat_* and GroupChatManager_* cases moved out of the old
AgentWorkflowBuilderTests file. They exercise the
`GroupChatWorkflowBuilder` type (returned by
`AgentWorkflowBuilder.CreateGroupChatBuilderWith`), so a dedicated
top-level test class - matching the convention reserved by the plan
for HandoffWorkflowBuilderTests / MagenticWorkflowBuilderTests - is
the right home. Cross-class helper references qualify with
`AgentWorkflowBuilderTests.DoubleEchoAgent` and
`AgentWorkflowBuilderTests.RunWorkflowAsync`.
The outer partial class is `static` (and nested classes carry the
instance test methods) because the outer holds only static helpers;
this satisfies CA1052 without suppressions and is invisible to xUnit
discovery, which finds tests on the nested classes as
`AgentWorkflowBuilderTests.SequentialTests.*` etc.
Validation: `dotnet build` clean on both target frameworks; all 547
tests in Microsoft.Agents.AI.Workflows.UnitTests pass on net10.0.

* feat: introduce OutputTag, Futures, and tag-aware WorkflowBuilder API
Phase 2 of the .NET Workflows outputs overhaul. Additive code change
only - no observable runtime behavior change. The runner still uses the
legacy bypass for AgentResponse / AgentResponseUpdate payloads, and the
new `Futures.EnableAgentResponseOutputTaggingAndFiltering` flag defaults
to false. Phase 3 will wire the flag into the runner; this commit only
introduces the types and the builder API.
New public surface:
* `OutputTag` (readonly struct): wraps a string Value with ordinal
equality (IEquatable, GetHashCode, == / !=) so it can participate as a
HashSet element. Internal ctor closes the set. One public singleton:
`OutputTag.Intermediate`. Terminal / regular outputs carry no tag
(empty Tags set). JSON-serialized as a bare string via
[JsonConverter(typeof(OutputTagJsonConverter))], with the converter
rehydrating to the well-known singleton on read.
* `Futures` (static class): hosts opt-in pre-GA behavior switches.
First flag is `EnableAgentResponseOutputTaggingAndFiltering`; XML doc
captures the v2.0.0 obsoletion / v3.0.0 removal lifecycle.
* `WorkflowOutputEvent.Tags`: `HashSet<OutputTag>` exposed directly
(concrete collection, matches the JSON-serialization convention used
for `WorkflowInfo.OutputExecutorIds`). Never null; empty for legacy /
terminal events. New ctors take a single `OutputTag` or
`IEnumerable<OutputTag>?`; the existing (data, executorId) ctor
remains and produces an untagged event. `HasTag(OutputTag)` helper.
`AgentResponseEvent` and `AgentResponseUpdateEvent` gain matching
tag-accepting ctors forwarding to the base.
* `WorkflowOutputEventExtensions.IsIntermediate(this WorkflowOutputEvent)`:
extension method returning `evt.HasTag(OutputTag.Intermediate)`. The
preferred way to ask "is this an intermediate output?" without
reaching into the Tags set.
* `WorkflowBuilder.WithOutputFrom(IEnumerable<ExecutorBinding>, OutputTag)`
and `WorkflowBuilder.WithOutputFrom(ExecutorBinding, OutputTag)`:
forward-looking tagged overloads. The IEnumerable form is the primary
tagged surface; the single-executor form is a convenience for the
common one-executor case. Currently usable for the
`OutputTag.Intermediate` singleton; will become the primary surface
once the `OutputTag` constructor is opened to user-defined tags in
a future release. Callers in this release should prefer the
intent-specific `WithIntermediateOutputFrom` extension for the
intermediate case. Tags accumulate across repeated calls; same tag
repeated dedupes via the HashSet.
* `WorkflowBuilderExtensions.WithIntermediateOutputFrom(this WorkflowBuilder, IEnumerable<ExecutorBinding>)`:
helper that forwards to `WithOutputFrom(executors, OutputTag.Intermediate)`.
Takes an IEnumerable (matching the tagged WithOutputFrom shape) -
callers pass collection literals: `builder.WithIntermediateOutputFrom([a, b])`.
XML doc remarks call out the Futures-flag interaction and the
AIAgent-payload forwarding contract.
Internal shape changes:
* `WorkflowBuilder._outputExecutors`: HashSet<string> -> Dictionary<
string, HashSet<OutputTag>>. The value set is empty for executors
designated only via the untagged WithOutputFrom; contains Intermediate
(and possibly future tags) otherwise.
* `Workflow.OutputExecutors`: HashSet<string> -> Dictionary<string,
HashSet<OutputTag>>.
* `OutputFilter.CanOutput`: `Contains(id)` -> `ContainsKey(id)`.
* `WorkflowInfo.OutputExecutorIds`: HashSet<string> -> Dictionary<
string, HashSet<OutputTag>>, with a custom JsonConverter that reads
both the new map shape (`{id: ["intermediate", ...]}`) and the legacy
array shape (`[id1, id2]`, where each id is treated as an untagged
output). Always writes the map shape. IsMatch updated to compare
per-id tag sets.
Tests landing in this commit (per the test-with-feature principle):
* `OutputTagTests.cs` (6 tests): KnownValues, EqualityIsOrdinalOnValue,
DefaultStructValueIsDistinct (default(OutputTag) does not collide
with the Intermediate singleton in a HashSet),
GetHashCodeMatchesEquals, JsonConverter_RoundtripsValueAsString,
ConstructorIsInternal (reflection-based assertion that the (string)
ctor is `internal`).
* `WorkflowBuilderTests.cs` adds 7 new tests pinning the builder
API contract: RegistersWithEmptyTagSet, AddsIntermediateTag,
MultipleExecutorsAllUntagged, ThenIntermediate_AccumulatesTags,
RepeatedDedupes, OnlyRegistersWithoutPriorWithOutputFrom,
TracksExecutorBinding.
* `BackwardsCompatibility/JsonCheckpointSerializationTests.cs`
(new folder + file, 5 tests): event-level ctor contract tests
(single-tag, no-tag, multi-tag — the last with a custom tag);
IsIntermediate() asserted; load-bearing JSON BC tests for
`WorkflowInfo.OutputExecutorIds` -
`WorkflowOutputExecutorsReadsLegacyArrayShape` (legacy ids map to
empty tag sets) and `WorkflowOutputExecutorsWritesMapShape`.
The plan's three JSON round-trip tests for `WorkflowOutputEvent.Tags`
were dropped: `WorkflowEvent` is not currently a serialized checkpoint
shape (see the comment in WorkflowsJsonUtilities.cs about events not
being persisted), so there is no real back-compat surface to pin
through JSON. They are substituted with in-process ctor/property
round-trip tests that exercise the `Tags` / `HasTag` / `IsIntermediate`
contract.
Validation: full `Microsoft.Agents.AI.Workflows.UnitTests` suite runs
green on net10.0 (565 passing, 0 failing). Core library builds clean
on net472, netstandard2.0, net8.0, net9.0, and net10.0. Test project
builds clean on net472 + net10.0.

* feat: route AgentResponse(Update) through the output filter under a Futures flag
`InProcessRunnerContext.YieldOutputAsync` historically special-cased AgentResponse and
AgentResponseUpdate payloads: it built the typed event subclass and emitted it directly,
bypassing the output filter. Rewrites the method so that:
- When `Futures.EnableAgentResponseOutputTaggingAndFiltering` is `false` (the current
default), AgentResponse(Update) keep the legacy bypass — emitted as
AgentResponseEvent / AgentResponseUpdateEvent with no tags. Existing callers see no
behavior change.
- When the flag is `true`, AIAgent payloads flow through the output filter just like
every other payload type: undesignated sources are dropped, and the emitted event
carries the source's tag set (empty for terminal `WithOutputFrom`, `{Intermediate}`
for `WithIntermediateOutputFrom`, the set union when both designations apply).
Non-AIAgent (POCO) outputs also now carry the source's tag set on the emitted
WorkflowOutputEvent unconditionally — additive, since no existing assertion inspected
Tags. Subclass events (`AgentResponseEvent` / `AgentResponseUpdateEvent`) continue to
be emitted under both modes so `switch (evt) { case AgentResponseEvent: ... }`
consumer code keeps matching.
Adds `OutputFilter.TryGetTags` as the tag-aware lookup used by the runner.
`OutputFilter.CanOutput` is kept (still used by the existing sync tests in
`OutputFilterTests.cs`).
Tests
-----
- `Futures/Futures.AgentResponseOutputFilteringAndTaggingTests.cs` (new): the F1–F13
matrix from the plan, covering every combination of `(flag on/off) × (designation)
× (payload shape)`. Uses a `FuturesScope` IDisposable + a `FuturesSerial` xUnit
collection (DisableParallelization = true) to keep the process-global flag from
leaking across parallel tests.
- `OutputFilterTests.cs`: four new `Test_OutputFilter_…` cases for the `TryGetTags`
surface (empty-tag-set for terminal designation, `{Intermediate}` for intermediate
designation, union for accumulated designation, `false` for unregistered).
582/582 unit tests pass on net10.0 (565 baseline + 17 new).

* feat: tag-aware defaults and designation API on orchestration builders
Aligns the .NET orchestration builders with Python's output / intermediate-output
distinction. Each builder either applies a Python-aligned default designation set or
replays the user's explicit `WithOutputFrom` / `WithIntermediateOutputFrom` calls,
never both.
Static `AgentWorkflowBuilder.BuildSequential` / `BuildConcurrent` apply defaults
unconditionally (no user-facing fluent surface to take control through):
- Sequential: terminal `end` + every agent designated intermediate.
- Concurrent: terminal `end` + every agent and per-agent accumulator designated
intermediate.
The three fluent instance builders memoize agent-typed designation calls in a
`Dictionary<AIAgent, HashSet<OutputTag>>` (empty set = terminal-only, non-empty =
intermediate tag(s)) so repeated calls dedupe naturally. They replay the entries
at `Build()` time, suppressing defaults when any call has been made:
- `HandoffWorkflowBuilder` / `HandoffWorkflowBuilderCore<TBuilder>` (also picked up
by the obsolete `HandoffsWorkflowBuilder` via inheritance).
Default: terminal `HandoffEnd` + every handoff agent intermediate.
(Bug fix: legacy code relied on `WithOutputFrom(end)` to bind `HandoffEnd`. The
new explicit-designation path bypasses that, so `Build()` now calls
`BindExecutor(end)` unconditionally to keep validation happy.)
- `GroupChatWorkflowBuilder` — default: terminal host + every participant intermediate.
- `MagenticWorkflowBuilder` — default: terminal orchestrator + every team member
intermediate.
Designating a non-participant agent throws `InvalidOperationException`.
The bare `WorkflowBuilder` default is unchanged — only the orchestration-style
builders gain implicit defaults, matching the plan's non-goal.
Tests
-----
- `AgentWorkflowBuilder.SequentialTests` / `.ConcurrentTests`: one default-spec
assertion each.
- `GroupChatWorkflowBuilderTests`: defaults-match-spec, explicit-replaces-defaults,
non-participant throws.
- `HandoffWorkflowBuilderTests` (new file): same three.
- `MagenticWorkflowBuilderTests` (new file): same three.
593/593 unit tests pass on net10.0 (582 baseline + 11 new).

* feat: WorkflowHostAgent forwards AgentResponseEvent unconditionally under Futures-on
Aligns the .NET Workflow-as-Agent surface with Python `as_agent`. Under
`Futures.EnableAgentResponseOutputTaggingAndFiltering = true`,
`WorkflowSession.InvokeStageAsync` now forwards `AgentResponseEvent`
unconditionally — joining `AgentResponseUpdateEvent` in ignoring the host's
`includeWorkflowOutputsInResponse` switch. That switch keeps governing the
generic `WorkflowOutputEvent` path for non-AIAgent payloads, where it is
further short-circuited by an `IsIntermediate()` check (tagged intermediate
outputs always surface).
Under Futures-off the legacy asymmetry is preserved: `AgentResponseUpdateEvent`
always forwarded, `AgentResponseEvent` gated by `includeWorkflowOutputsInResponse`.
Back-compat: with `Futures.EnableAgentResponseOutputTaggingAndFiltering` left at
its default `false`, observable behavior is identical to before.
`Futures` documentation gains a remark explaining the `Workflow.AsAIAgent()`
interaction in both flag states.
Runner fix
----------
`InProcessRunnerContext.YieldOutputAsync` now skips `Executor.CanOutput` for
AgentResponse-shaped payloads under both Futures branches. `AIAgentHostExecutor`
doesn't declare AgentResponse(Update) in its `Yields` set, so the historical
legacy bypass had silently skipped the check; Phase 3's Futures-on path was
running it and would reject AIAgent payloads. AIAgent-shaped payloads are now
always a valid output shape, matching the legacy bypass semantics.
Phase 4 follow-on
-----------------
Switched the three orchestration-builder designation-replay loops to iterate
`Dictionary.Keys` with a value lookup instead of constructing/destructuring
`KeyValuePair<,>`. Cleaner shape and avoids the netstandard2.0 / net472
`KeyValuePair<,>.Deconstruct` unavailability that surfaced when this branch
multi-TFM-built.
Tests
-----
`WorkflowHostSmokeTests.IntermediateForwarding` (new nested class, 6 tests):
- intermediate AgentResponse forwarded past the include-outputs gate (Futures on)
- terminal AgentResponse forwarded unconditionally (Futures on)
- terminal AgentResponse gated by include flag (Futures off, legacy)
- undesignated AIAgent executor emits no AgentResponseEvent under Futures-on
- legacy bypass still emits AgentResponseEvent under Futures-off
- intermediate tag is observable via `update.RawRepresentation`
The class joins the `FuturesSerial` xUnit collection so the process-global flag
is serialized against other Futures-toggling tests.
599/599 unit tests pass on net10.0 (593 baseline + 6 new).

* feat: SequentialWorkflowBuilder and ConcurrentWorkflowBuilder, OrchestrationBuilderBase
Promotes the Sequential and Concurrent orchestration shapes to first-class fluent
builder classes, matching Handoff / GroupChat / Magentic. Users can call
`WithOutputFrom(agents)` / `WithIntermediateOutputFrom(agents)` to control which
agents are designated output / intermediate sources; when no designation call is
made, the Python-aligned defaults apply (terminal aggregator output + every agent
intermediate; Concurrent also tags per-agent accumulators).
`AgentWorkflowBuilder.BuildSequential(...)` and `BuildConcurrent(...)` are kept
and now delegate to the new builders; observable behavior unchanged. Five static
factories now mirror each other:
- `AgentWorkflowBuilder.CreateSequentialBuilderWith(params IEnumerable<AIAgent>)`
- `AgentWorkflowBuilder.CreateConcurrentBuilderWith(params IEnumerable<AIAgent>)`
- `AgentWorkflowBuilder.CreateHandoffBuilderWith(AIAgent)` (already existed)
- `AgentWorkflowBuilder.CreateGroupChatBuilderWith(Func<...>)` (already existed)
- `AgentWorkflowBuilder.CreateMagenticBuilderWith(AIAgent)` (new)
OrchestrationBuilderBase
------------------------
New abstract `OrchestrationBuilderBase<TBuilder>` unifies the shared fluent
surface across all five orchestration builders: `WithName`, `WithDescription`,
`WithOutputFrom`, `WithIntermediateOutputFrom`, and the
`ApplyOutputDesignations(builder, agentMap, kind, applyDefaults)` helper that
either replays the user's designations or invokes the orchestration-specific
defaults.
Removes ~150 LOC of duplicated designation-management code from the four
non-Handoff builders, plus the equivalent from `HandoffWorkflowBuilderCore`.
Tests
-----
- New `SequentialWorkflowBuilderTests.cs` / `ConcurrentWorkflowBuilderTests.cs`
(replace the old `AgentWorkflowBuilder.{Sequential,Concurrent}Tests.cs`
nested-class files). Method names normalized to
`Test_<BuilderType>_<Scenario>[Async]`.
- Shared helpers (`DoubleEchoAgent`, `DoubleEchoAgentWithBarrier`,
`WorkflowRunResult`, `RunWorkflow*`) moved from the old
`AgentWorkflowBuilderTests` partial class into a new
`OrchestrationTestHelpers` static class in `OrchestrationTestHelpers.cs`.
Downstream test files (Group Chat, Handoff, Sequential, Concurrent) updated
to qualify with `OrchestrationTestHelpers.*`.
- A new `AgentWorkflowBuilderTests.cs` covers the static surface directly:
`BuildSequential` / `BuildConcurrent` invariants and aggregator wiring, plus
null-rejection + round-trip checks for every `Create*BuilderWith` factory.
- New AsAgent intermediate-suppression tests on a nested `AsAgentForwarding`
class for each of Sequential and Concurrent: build with only the terminal
agent designated via `WithOutputFrom`, run via `AsAIAgent(...)`, assert via
`AgentResponseUpdate.AuthorName` that intermediate agents do not surface.
Both join the `FuturesSerial` collection.
- New `Test_<Builder>_WithDescriptionPropagatesToWorkflow` smoke tests on
Sequential and Concurrent (newly available via the base class).
625/625 unit tests pass on net10.0.

* Address PR review: remove __slots__ and add typed schemas for tool params
- Remove __slots__ from TodoItem, TodoInput, and TodoCompleteInput classes
(not needed for low-instance-count objects and hinders dev scenarios)
- Add _TodoAddItemSchema and _TodoCompleteItemSchema TypedDicts to provide
proper JSON schema for todos_add and todos_complete tool parameters
- Use typing_extensions for Python 3.10 compatibility

* Remove unnecessary [Experimental] attributes from MCP package
The package is already alpha, so the [Experimental] attribute is redundant.
Removed from both AgentSkillsProviderBuilderMcpExtensions and
AgentMcpSkillsSource classes.

* Make Agent_Step06_McpBasedSkills self-contained and add to verify-samples
Embed an internal MCP server (launched via --server flag as a child process)
that serves skill://index.json and skill://unit-converter/SKILL.md resources,
replacing the external MCP_SKILLS_ENDPOINT dependency. The sample now uses
StdioClientTransport and a fixed prompt instead of an interactive loop.
Added SampleDefinition to AgentsSamples.cs for automated verification.

* .NET: Refactor AgentSkill API to async resource and script lookup
Replace property-based AgentSkill.Content, Resources, and Scripts with
async-by-name lookup methods plus boolean availability flags:
- Content (string getter) -> GetContentAsync(CancellationToken)
- Resources (full list) -> HasResources + GetResourceAsync(name, ct)
- Scripts (full list) -> HasScripts + GetScriptAsync(name, ct)
This makes the API friendlier for sources like MCP where enumerating all
resources up front is expensive or impossible, and allows skill implementations
to fetch content lazily.
Subclass changes:
- AgentFileSkill and AgentInlineSkill implement the new async API while
preserving content caching.
- AgentClassSkill<TSelf> keeps virtual Resources/Scripts properties for
reflection-based discovery and seals the new HasResources/HasScripts/
GetResourceAsync/GetScriptAsync overrides. Its previously non-thread-safe
lazy initialization is replaced with Lazy<T> (default thread-safety) wired
up in a new protected constructor, so concurrent first-access from multiple
threads is safe.
- AgentSkillsProvider calls the new async API and exposes
ead_skill_resource
/ load_skill /
un_skill_script tools that await the per-name lookups.
Includes baseline CompatibilitySuppressions.xml entries for the removed
property getters.
Tests:
- Direct coverage for HasResources, HasScripts, GetResourceAsync, and
GetScriptAsync on all three skill implementations (positive, missing-name,
and no-resources/no-scripts cases).
- Thread-safety regression test for AgentClassSkill<TSelf> that exercises
concurrent first-access to Resources, Scripts, and GetContentAsync from
many tasks and asserts all observers see the same cached instance.
- Provider-level coverage for the
ead_skill_resource tool (invocation +
error paths) and for the previously untested error paths of load_skill
and
un_skill_script (empty names, skill/resource/script not found).

* Address PR review comments
- Move GetScriptAsync inside try/catch in RunSkillScriptAsync for error-handling parity
- Remove dead _reflectedResources branch from AgentSkillTestExtensions
- Fix XML docs to reference virtual Resources/Scripts properties (not sealed methods)
- Add Async suffix to async test methods per naming convention
- Make no-await tests synchronous to eliminate CS1998

* Remove HasResources and HasScripts properties from AgentSkill
Drop the virtual HasResources and HasScripts properties from AgentSkill
and all concrete subclasses (AgentFileSkill, AgentInlineSkill,
AgentClassSkill). AgentSkillsProvider now always includes all three
tools (load_skill, read_skill_resource, run_skill_script) and both
instruction blocks, since the tools already handle missing
resources/scripts gracefully.

* .NET: Add Hosted-AgentSkills sample for Foundry Skills integration
Add a new hosted agent sample that demonstrates how to load behavioral
guidelines from Foundry Skills at startup using AgentSkillsProvider and
the progressive disclosure pattern (advertise -> load on demand).
The sample:
- Downloads SKILL.md files from Foundry via ProjectAgentSkills SDK
- Extracts ZIP archives with zip-slip protection
- Wires skills into AgentSkillsProvider as an AIContextProvider
- Hosts the agent via the Responses protocol
Ships two Contoso Outdoors skills matching the Python sample (PR #5822):
- support-style: tone, formatting, signature guidelines
- escalation-policy: when and how to escalate tickets
Includes convenience provisioning gated behind PROVISION_SAMPLE_SKILLS
env var, clearly documented as NOT a production pattern.
Closes#5776

* .NET: Add unit tests and integration test for Hosted-AgentSkills
Unit tests (14 tests, all passing):
- ZIP extraction with zip-slip guard (valid archive, traversal attack,
sibling-prefix attack, directory entries)
- Skill name validation (rejects dots, separators, traversal patterns)
- AgentSkillsProvider with downloaded skills (advertises both skills,
load_skill returns canary tokens, unknown skill returns error)
Container integration test:
- New 'agent-skills' scenario in the test container that creates
Contoso Outdoors skills on disk and wires AgentSkillsProvider
- AgentSkillsHostedAgentFixture + 4 integration tests verifying:
- Routine questions load support-style skill (STYLE-CANARY-3318)
- Escalation triggers load escalation-policy (ESC-CANARY-7742)
- Skills are advertised in system prompt
- load_skill tool is invoked via FunctionCallContent

* .NET: Add smoke test, bootstrap, and docs for agent-skills integration
- Add scripts/smoke.ps1 for local Docker smoke testing: builds the
contributor image, runs the container, verifies both skills are loaded
via canary tokens (STYLE-CANARY-3318, ESC-CANARY-7742)
- Add 'agent-skills' to the bootstrap script scenario list
- Add agent-skills row to the integration test README scenarios table
- Exclude HostedAgentSkillsPatternTests from net472 (uses net8.0+ APIs)

* .NET: Update commented-out package versions to latest across all hosted samples
Update the end-user PackageReference versions (in the commented-out
sections) from 1.0.0 to the current latest NuGet versions:
- Microsoft.Agents.AI: 1.6.1
- Microsoft.Agents.AI.Foundry: 1.6.1-preview.260514.1
- Microsoft.Agents.AI.Foundry.Hosting: 1.6.1-preview.260514.1
- Microsoft.Agents.AI.Hosting: 1.6.1-preview.260514.1
- Microsoft.Agents.AI.OpenAI: 1.6.1
- Microsoft.Agents.AI.Workflows: 1.6.1
Also adds explicit versions to Hosted-Workflow-Handoff which had bare
PackageReference entries without Version attributes.

Fix three interlocked bugs that prevent parallel tool calls from rendering
correctly in AG-UI protocol clients:
Bug #1: Scope synthetic MessageId fallback to text events only. The shared
streamingMessageId was leaking into ToolCallStartEvent.ParentMessageId,
causing all parallel tool calls to collapse into one FE card.
Bug #2: Make ToolCallResultEvent.MessageId deterministically unique using
result-{CallId} format. MEAI's FunctionInvokingChatClient batches all
results with a shared MessageId, collapsing them in FE reconciliation.
Bug #3: Coalesce consecutive assistant-tool-call messages in AsChatMessages.
Once Bug #1 is fixed, the FE produces separate AGUIAssistantMessage per
tool call. On multi-turn replay these become consecutive assistant messages
without intervening tool results, triggering HTTP 400 from Azure OpenAI.
Remove the now-dead ContainsToolResult helper introduced by PR #5800.
