Description
🏥 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The "Daily Test Coverage Improver" workflow failed due to multiple critical issues: outdated lock file warning, agent execution errors, pull request creation failure, and discussion comment failures.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
- Run: 19218822698
- Commit: 8abd9cd - "Optimize SC2002 useless cat patterns in analysis workflows (Optimize SC2002 useless cat patterns in analysis workflows #3547)"
- Trigger: schedule (automated daily run)
- Duration: 12m 3s
- Date: 2025-11-10 02:35 UTC
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 Outdated Lock File (WARNING)
WARNING: Lock file '.github/workflows/daily-test-improver.lock.yml' is outdated!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Impact: The workflow may be running with an outdated configuration that doesn't reflect recent changes to the markdown source file.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.
- Job: add_comment
- Impact: Unable to comment on discussion
- Root Cause: Discussion Daily Test Coverage Improver - Add tests for console render formatting functions #2654 does not exist or was deleted

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git pushPriority: CRITICAL - Prevents running outdated workflow logic
🔴 HIGH - Fix Pull Request Creation
- Investigate SyntaxError: Review the JavaScript/JSON generation logic in the create_pull_request safe output handler
- Validate Patch Format: Ensure
aw.patchartifact is properly formatted - Add Error Handling: Implement try-catch around JSON parsing in PR creation logic
- Test Locally:
# Download aw.patch artifact and validate format gh run download 19218822698 -n aw.patch cat aw.patch
🟡 MEDIUM - Fix Discussion Comment Logic
- Add Existence Check: Verify discussion exists before attempting to comment
- Update Workflow: Either:
- Use
create_discussioninstead ofadd_comment - Add conditional logic to check if discussion Daily Test Coverage Improver - Add tests for console render formatting functions #2654 still exists
- Use
- Improve Error Messages: Provide clearer guidance when discussion not found
🟢 LOW - Address Agent Execution Errors
- React Key Prop: Update Copilot CLI or adjust output rendering to include unique keys
- Go Test Failures: Review test execution logic and exit code handling
- Coverage Generation: Validate coverage step logic and error recovery
Prevention Strategies
1. Lock File Synchronization
- Add Pre-Commit Hook: Automatically run
gh aw compilewhen.mdfiles 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 processesNext Steps
- ✅ Immediate: Regenerate lock file for daily-test-improver workflow
- 🔄 Short-term: Fix PR creation syntax error and add robust error handling
- 📅 Long-term: Implement comprehensive CI checks for lock file synchronization
