🏥 CI Failure Investigation - Run #17

Summary

The "Daily Test Coverage Improver" workflow failed due to multiple critical issues: outdated lock file warning, agent execution errors, pull request creation failure, and discussion comment failures.

Failure Details

Root Cause Analysis

1. Outdated Lock File (WARNING)

WARNING: Lock file '.github/workflows/daily-test-improver.lock.yml' is outdated! 
The workflow file '.github/workflows/daily-test-improver.md' has been modified more recently.
Run 'gh aw compile' to regenerate the lock file.

Impact: The workflow may be running with an outdated configuration that doesn't reflect recent changes to the markdown source file.

2. Agent Execution Errors

Multiple errors were detected during agent execution:

Error 1: React Key Prop Error

Each child in a list should have a unique "key" prop.
  • Pattern: Copilot CLI timestamped ERROR messages
  • Time: 2025-11-10T02:43:33.251Z
  • Impact: Frontend rendering issue in Copilot CLI output

Error 2: Go Test Execution Failure

Go tests failed with exit code $EXIT_CODE
  • Context: Coverage generation step
  • Impact: Test execution failed, preventing coverage report generation

Error 3: Generic ERROR messages

Multiple errors related to test validation and npm package handling.

3. Pull Request Creation Failure (CRITICAL)

Unhandled error: SyntaxError: Unexpected token '}'
  • Job: create_pull_request
  • Impact: Failed to create PR with improvements
  • Severity: HIGH - Objective not achieved

4. Discussion Comment Failure

GraphqlResponseError: Request failed due to following response errors:
- Could not resolve to a Discussion with the number of 2654.

Failed Jobs and Errors

Job Sequence

  1. activation - 8s - succeeded
  2. agent - 10m 40s - completed with errors (exit code 2)
  3. detection - 23s - succeeded
  4. ⏭️ create_discussion - skipped
  5. create_pull_request - 29s - FAILED (SyntaxError)
  6. ⏭️ missing_tool - skipped
  7. add_comment - 5s - FAILED (Discussion not found)

Error Summary

  • Total Errors: 10
  • Critical: 2 (PR creation, discussion comment)
  • Warnings: 1 (outdated lock file)
  • Exit Code: 2 (agent job)

Investigation Findings

Artifacts Produced

  • agent-stdio.log (5.62 KB) - Agent execution logs
  • agent_output.json (2.54 KB) - Structured agent output
  • agent_outputs (46.1 KB) - Full agent outputs
  • aw.patch (2.95 KB) - Generated patch file
  • aw_info.json (495 B) - Workflow metadata
  • prompt.txt (6.65 KB) - Agent prompt
  • safe_output.jsonl (2.51 KB) - Safe outputs data
  • threat-detection.log (464 B) - Security scan results

Note: Despite failures, artifacts were successfully uploaded, suggesting the core workflow logic completed but post-processing failed.

Recent Commits Context

The triggering commit was part of PR #3547 which optimized SC2002 shellcheck patterns. Recent commits include:

Recommended Actions

🔴 IMMEDIATE - Fix Lock File Synchronization

cd /path/to/repo
gh aw compile daily-test-improver
git add .github/workflows/daily-test-improver.lock.yml
git commit -m "chore: regenerate daily-test-improver lock file"
git push

Priority: CRITICAL - Prevents running outdated workflow logic

🔴 HIGH - Fix Pull Request Creation

  1. Investigate SyntaxError: Review the JavaScript/JSON generation logic in the create_pull_request safe output handler
  2. Validate Patch Format: Ensure aw.patch artifact is properly formatted
  3. Add Error Handling: Implement try-catch around JSON parsing in PR creation logic
  4. Test Locally:
    # Download aw.patch artifact and validate format
    gh run download 19218822698 -n aw.patch
    cat aw.patch

🟡 MEDIUM - Fix Discussion Comment Logic

  1. Add Existence Check: Verify discussion exists before attempting to comment
  2. Update Workflow: Either:
  3. Improve Error Messages: Provide clearer guidance when discussion not found

🟢 LOW - Address Agent Execution Errors

  1. React Key Prop: Update Copilot CLI or adjust output rendering to include unique keys
  2. Go Test Failures: Review test execution logic and exit code handling
  3. Coverage Generation: Validate coverage step logic and error recovery

Prevention Strategies

1. Lock File Synchronization

  • Add Pre-Commit Hook: Automatically run gh aw compile when .md files change
  • Add CI Check: Validate lock files are up-to-date in CI pipeline
  • Documentation: Add reminder in CONTRIBUTING.md to run compile before commit

2. Safe Output Robustness

  • JSON Validation: Add schema validation before creating PRs/comments
  • Graceful Degradation: If PR creation fails, create an issue instead
  • Existence Checks: Always verify resources exist before operating on them

3. Agent Error Handling

  • Error Categorization: Distinguish between fatal and non-fatal errors
  • Retry Logic: Implement exponential backoff for transient failures
  • Detailed Logging: Capture full error context for debugging

Historical Context

Based on the search results, similar issues have been encountered:

  • Issue Classifier failures - Agent execution problems
  • Docker registry outages - External dependency failures
  • Safe output job failures - Missing artifacts or misconfiguration

Pattern: This workflow has multiple failure modes that need systematic hardening.

AI Team Self-Improvement

Add to .github/instructions.md:

## Lock File Management
- **ALWAYS run `make recompile` before committing** workflow changes
- Verify `.lock.yml` files are up-to-date before PR submission
- If you modify a `.md` workflow file, regenerate its corresponding `.lock.yml`

## Safe Output Error Handling
- **ALWAYS validate** that target resources (discussions, issues, PRs) exist before operations
- **ALWAYS add try-catch** around JSON parsing and API calls
- Provide **graceful fallback** when primary safe output operations fail
- Include **existence checks** for all GitHub resources before commenting/updating

## Agent Execution Robustness
- **ALWAYS check exit codes** from shell commands in agent steps
- **ALWAYS log detailed error context** when commands fail
- Implement **retry logic** for transient failures
- Use **timeout limits** to prevent hanging processes

Next Steps

  1. Immediate: Regenerate lock file for daily-test-improver workflow
  2. 🔄 Short-term: Fix PR creation syntax error and add robust error handling
  3. 📅 Long-term: Implement comprehensive CI checks for lock file synchronization
