Description

  1. New agent_report.json per agent at eval_/agent_name/ — contains cross-run aggregations: by_metric, by_conversation, quality_score
  2. eval_report.json slimmed to agent headlines (identity + overall) + comparison (deltas, rankings)
  3. per_run excluded from both reports — raw data lives in per-run files only
  4. Field sets (_AGENT_REPORT_FIELDS, _EVAL_REPORT_AGENT_FIELDS) control what each report includes — easy to expand
  5. No model changes, no consolidation changes — purely output structure

Summary by CodeRabbit

  • New Features

    • Behavioral evaluations now provide a dedicated report for each consolidated agent.
    • Aggregate evaluation reports now present concise headline information for each agent, while detailed results remain available in the individual reports.
    • Report metadata uses standardized ISO-8601 timestamps for improved consistency and readability.
  • Tests

    • Expanded coverage verifies individual and aggregate report contents and confirms complete agent data handling.

Review Change Stack

Walkthrough

The behavioral pipeline now writes detailed reports for each consolidated agent and filters aggregate reports to headline fields. Tests cover per-agent serialization, aggregate serialization, field coverage, and orchestrator integration.

Changes

Behavioral report persistence

Layer / File(s) Summary
Report serialization and validation
src/lightspeed_evaluation/pipeline/behavioral/report.py, tests/unit/pipeline/behavioral/test_report.py
Adds save_agent_report for detailed agent data. save_report now writes headline agent fields. Tests cover serialization, metadata, excluded per-run data, and field coverage.
Orchestrator report generation
src/lightspeed_evaluation/pipeline/behavioral/orchestrator.py, tests/unit/pipeline/behavioral/test_orchestrator.py
The orchestrator saves one report per consolidated agent before saving and logging the aggregate report. Tests verify both save operations.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: ⚪ Minimal · up to 6ded2

The PR restructures evaluation report files without changing model or consolidation behavior. Only localized test follow-ups and an unverified path-validation question remain, so no actionable merge-blocking risk is supported by the current evidence.

catch save_agent_report write or serialization failures for each agent, log the
agent name and failure, and continue processing remaining agents. Keep aggregate
comparison and save_report execution reachable when other reports succeed,
preserving best-effort report generation.

In `@tests/unit/pipeline/behavioral/test_report.py`:
- Around line 71-81: Update test_agent_headlines_only to explicitly assert that
quality_score is absent from the agent data loaded from eval_report.json,
alongside the existing exclusions for by_metric, by_conversation, and per_run.

44-49: 🔒 Security & Privacy

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify report-directory containment.

Line 44 and Line 66 create directories from agent_dir and output_dir. The supplied caller derives agent_dir from agent_name. If these values can contain untrusted absolute paths or .. components, report generation can write outside the evaluation directory. Verify validation at the input boundary. If inputs are untrusted, derive paths from a validated root and reject unsafe agent names.

Also applies to: 66-74

- Around line 553-555: Update the test around mock_agent_save to assert that
each save_agent_report call receives the per-agent destination eval_dir/model_a
as its second argument, not merely that the call count matches. Apply the same
argument assertion to the corresponding case near the other reported location.

In `@tests/unit/pipeline/behavioral/test_report.py`:
- Around line 55-60: Update the report serialization test around
save_agent_report to compare the loaded data mapping against the complete
expected agent report from the fully populated fixture, including identity,
overall, per-metric, per-conversation, and quality_score fields, rather than
asserting only selected keys and values.
