Elaine Dazzio" Date: Thu, 16 Apr 2026 15:39:09 -0400 Subject: [PATCH 10/13] 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.

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.

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.
