Add agent diagnostic snapshot capture - #550
Conversation
Summary by CodeRabbit
WalkthroughThe PR updates product and contract versions, adds generated MCP schema verification to build checks, expands diagnostic telemetry policy coverage, and adds CLI and collector tests for schemas, bridge behavior, persistence, redaction, and lifecycle handling. ChangesCLI contract and diagnostics
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds diagnostic snapshot capture and persistence, but the current head still has bounded issues that can cause test compilation failures, miss contract drift, or make build enforcement unreliable on Windows and for certain schema patterns. Merge should wait for these fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@eng/build/BuildCliContractLoop.cs`:
- Around line 49-53: Update the file filters in both the root collection and
VerifyCliSerializesContractsOnly to use platform-independent separator handling
when excluding obj and bin directories. Normalize each path or compare using the
platform directory separator, while preserving the existing generated-file
exclusions.
- Around line 61-100: Update the generatedSchemaFields collection to detect
duplicate declarator names mapping to different ToolSchemas artifacts across
roots; report each collision as an offender instead of overwriting the existing
mapping. Extend the raw-schema scan alongside the current
LiteralExpressionSyntax traversal to inspect InterpolatedStringTextSyntax
content, so interpolated raw JSON containing inputSchema or outputSchema is also
rejected.
In `@tests/Qyl.Cli.Tests/DiagnosticSnapshotTests.cs`:
- Line 108: Update the oversized string setup in DiagnosticSnapshotTests to
derive its length from DiagnosticSnapshotCapture’s named line-length limit,
adding one beyond that limit instead of hardcoding 256 * 1024 + 1. Keep the
test’s oversized-input behavior unchanged.
- Around line 800-844: Update the DiagnosticSnapshotTests fixture validation
around ValidArgumentsJson, ReorderedArgumentsJson, and
DiagnosticSnapshotCapture.TryCreate so both handwritten JSON documents are
parsed and validated against ToolSchemas.RecordDiagnosticSnapshotInput before
being used. Prefer constructing the fixtures through the generated contract
types and serializing them, while preserving the reordered-property coverage;
ensure schema changes cause these interoperability tests to fail.
- Around line 651-667: Add the System.Diagnostics namespace import to
DiagnosticSnapshotTests.cs so the Activity, ActivityListener, ActivityContext,
ActivitySamplingResult, and ActivitySource references in
Telemetry_projection_emits_only_fixed_diagnostic_and_workflow_tags compile.
- Around line 60-63: Update the cleanup in DiagnosticSnapshotTests so the
background diagnostic drain is cancelled and awaited before deleting root. Then
make Directory.Delete(root, recursive: true) best-effort while preserving
cleanup even if deletion fails; use the existing drain cancellation/task symbols
rather than introducing unrelated changes.
In `@tests/Qyl.Collector.Tests/AiDiagnosticSpanEventPersistenceTests.cs`:
- Around line 65-66: Update the test fixture’s TraceId and SpanId values in
AiDiagnosticSpanEventPersistenceTests to use valid non-zero OTLP identifiers,
either with fixed non-zero byte sequences or generated identifiers; keep the
identifiers at the required 16-byte and 8-byte lengths.
- Line 33: Rename the test at
tests/Qyl.Collector.Tests/AiDiagnosticSpanEventPersistenceTests.cs:33 to follow
MethodName_Scenario_ExpectedResult, beginning with the exercised method name and
describing the persistence scenario and result. Also rename the test at
tests/Qyl.Collector.Tests/AiDiagnosticSpanEventPersistenceTests.cs:119 to begin
with AttributeKeySets and describe the rejected-key scenario and expected
result.
