Error Clusters

Cluster 1: Permission Error - Agent Assignment Failure

• Count: 1 occurrence
• Affected Jobs: Activation (agent assignment)
• Affected Workflows: Duplicate Code Detector
• Sample Error:

  ##[error] Could not assign agent: target repository is not writable.
  GraphQL mutation: replaceActorsForAssignable
  Type: FORBIDDEN
  

• Root Cause: The GITHUB_TOKEN used by the safe_outputs job lacks sufficient permissions to assign GitHub Copilot agents to issues using the replaceActorsForAssignable GraphQL mutation. This operation attempted to assign @copilot to issue Duplicate Code: close_* action config parsing/logging #15309.
• Impact: Low - Issue was created successfully. Only the automatic agent assignment failed. The issue remains actionable, just without an automatic assignee.

Root Cause Analysis

Permission-Related Issues

Issue: Agent Assignment FORBIDDEN Error

• Location: Safe outputs job attempting to assign @copilot to newly created issue

• Error Type: GraphQL API Permission Error (FORBIDDEN)

• Technical Details:

  • GraphQL mutation: replaceActorsForAssignable
  • Target: Issue Duplicate Code: close_* action config parsing/logging #15309 in github/gh-aw
  • Attempted assignee: @copilot (GitHub Copilot agent)
  • Error message: "Could not assign agent: target repository is not writable."

• Why This Happened:

  • The GITHUB_TOKEN permissions may not include agent assignment capabilities
  • Agent assignment might require GitHub App-level permissions
  • This operation may be restricted in certain repository contexts

• What Worked:

  • Issue creation succeeded ✅
  • Issue body with assignee mention (@copilot) was included ✅
  • All other safe outputs processed successfully ✅

• What Failed:

  • Automatic agent assignment via GraphQL API ❌

Recommendations

Critical Issues (Immediate Action Required)

None identified - The single failure is non-critical and has a clear workaround.

Bug Fixes Required

1. Handle Agent Assignment Errors Gracefully
   • Priority: High
   • File/Location: Safe outputs processing logic (activation handler)
   • Problem: Safe outputs job fails (marks entire job as failed) when agent assignment permission is denied, even though the core operation (issue creation) succeeded
   • Fix: Wrap agent assignment operations in try-catch and treat permission errors as warnings rather than failures. The job should succeed if the primary operation (create_issue) succeeds, regardless of activation step outcomes.
   • Affected Jobs: Any workflow that uses @mentions for agent assignment in safe output bodies
   • Code Change Needed:

     // Instead of:
     await assignAgent(issueId, agentLogin); // throws on permission error
     
     // Use:
     try {
       await assignAgent(issueId, agentLogin);
       core.info(`Successfully assigned \$\{agentLogin} to issue`);
     } catch (error) {
       if (error.type === 'FORBIDDEN') {
         core.warning(`Could not assign agent: \$\{error.message}`);
         core.info('Issue created successfully. Manual assignment may be required.');
       } else {
         throw error; // Re-throw unexpected errors
       }
     }

Configuration Changes

1. Investigate GitHub Token Permissions for Agent Assignment
   • Current: GITHUB_TOKEN has issues: write but may lack agent assignment capability
   • Recommended: Investigate whether additional permissions are needed:
     • GitHub App permissions for agent operations
     • Repository settings for agent assignments
     • Enterprise-level permissions
   • Reason: Understand if this is a permission configuration issue or an API limitation

Process Improvements

1. Make Agent Assignment Non-Blocking

   • Current State: Agent assignment failures cause safe output job to fail
   • Proposed: Treat agent assignment as an optional enhancement, not a required step
   • Benefits:
     • Higher safe output success rate
     • Clearer separation of concerns (content creation vs. assignment)
     • Better error messages for users

2. Add Permission Pre-Flight Checks

   • Current State: Permission errors are only discovered when operations are attempted
   • Proposed: Check for required permissions before attempting operations and skip unsupported actions with clear warnings
   • Benefits:
     • Predictable behavior
     • Better user experience with clear capability boundaries
     • Reduced error noise in logs

Work Item Plans

Work Item 1: Graceful Agent Assignment Error Handling

• Type: Bug Fix
• Priority: High
• Description: Modify safe output processing to treat agent assignment permission errors as non-fatal warnings rather than job failures. The core safe output operation (issue/PR/discussion creation) should be considered successful even if subsequent activation steps (like agent assignment) fail due to permissions.
• Acceptance Criteria:
  • Safe outputs job succeeds when issue/PR/discussion is created successfully, regardless of assignment outcome
  • Permission errors during agent assignment are logged as warnings, not errors
  • Job summary clearly indicates which operations succeeded and which were skipped due to permissions
  • Existing workflows continue to function without modification
• Technical Approach:
  1. Identify agent assignment code in safe output handlers (likely in activation or issue creation logic)
  2. Wrap assignment operations in try-catch blocks
  3. Check for GraphQL FORBIDDEN errors specifically
  4. Log warnings and continue execution for permission errors
  5. Update job status logic to consider primary operation (create_issue) success independently from activation success
• Estimated Effort: Small (4-6 hours including testing)
• Dependencies: None
• Files to Modify:
  • actions/setup/js/create_issue.cjs (or similar safe output handler)
  • Activation logic that processes @mentions

Work Item 2: Document Agent Assignment Limitations

• Type: Documentation
• Priority: Medium
• Description: Document known limitations around agent assignment in safe outputs, including required permissions and alternative approaches when automatic assignment fails.
• Acceptance Criteria:
  • Documentation clearly states agent assignment requirements
  • Alternative workflows are documented (manual assignment, workflow-level permissions)
  • Error messages reference the documentation
• Technical Approach:
  1. Research GitHub API requirements for replaceActorsForAssignable mutation
  2. Test agent assignment in different repository contexts (public/private/enterprise)
  3. Document findings in safe-outputs.md or relevant configuration docs
  4. Add troubleshooting section for common permission errors
• Estimated Effort: Medium (8-12 hours including research and testing)
• Dependencies: Work Item 1 (understanding the error handling helps document expected behavior)

Historical Context

Trends:

• This is the first safe output health audit, so no historical comparison is available
• The 96% success rate is a strong baseline for future monitoring
• No recurring patterns detected (only 1 failure across 26 jobs)

Comparison to Agent/Detection Jobs:

• Safe output jobs are performing well (96% success)
• The failure is isolated and has a clear root cause
• No systemic issues detected

Metrics and KPIs

• Overall Safe Output Success Rate: 96.0% ✅
• Most Reliable Job Type: create_pull_request (8 successful operations, 0 failures)
• Most Common Output Type: create_pull_request (8 occurrences)
• Zero Critical Failures: No data loss, corruption, or blocking issues ✅
• System Health: Excellent - Single non-critical permission error

Detailed Failure Analysis

Run §21977434383 - Duplicate Code Detector

Timeline:

1. 06:43:00 UTC - Activation job started ✅
2. 06:43:11 UTC - Agent job started ✅
3. 06:46:54 UTC - Agent job completed successfully ✅
4. 06:47:21 UTC - Safe outputs job started
5. 06:47:27 UTC - Issue creation succeeded ✅
6. 06:47:28 UTC - Agent assignment failed ❌
   • Error: "Could not assign agent: target repository is not writable"
   • GraphQL mutation: replaceActorsForAssignable
   • Type: FORBIDDEN
7. 06:47:30 UTC - Safe outputs job marked as failed ❌

What the Agent Produced:

• Safe output type: create_issue
• Issue title: "Duplicate Code: close_* action config parsing/logging"
• Issue body: Comprehensive analysis of duplicate code patterns in close_* actions
• Assignee mention in body: @copilot

Outcome:

• Issue was likely created successfully (primary operation)
• Automatic assignment to @copilot failed (activation operation)
• Safe outputs job reported as failed, causing workflow conclusion to be "failure"

User Impact:

• Minimal - The issue exists and is actionable
• Manual assignment or labeling can achieve the same result
• No data loss or corruption

Skipped Jobs Analysis

Run §21977637610 - CI Failure Doctor

Why It Was Skipped:
The safe_outputs job was skipped because the agent did not produce any safe outputs during its execution. This is normal and expected behavior.

Job Outcomes:

• Agent job: Completed successfully ✅
• Detection job: Skipped (no outputs to detect) ✓
• Safe outputs job: Skipped (no outputs to process) ✓
• Update cache memory job: Skipped (no cache updates needed) ✓

Status: Normal operation - no issues

Next Steps

Immediate Actions:

• Implement graceful error handling for agent assignment failures (Work Item 1)
• Monitor next 24 hours to confirm this is an isolated incident

Short-term Actions (1-2 weeks):

• Research GitHub API permissions for agent assignment (Work Item 2)
• Document agent assignment limitations and workarounds
• Review other activation operations for similar permission issues

Long-term Actions (1+ months):

• Establish daily safe output health monitoring
• Create alerting for success rate drops below 95%
• Build dashboard for safe output metrics over time

Conclusion

The safe output system is in excellent health with a 96% success rate over the last 24 hours. The single failure is a non-critical permission error that did not prevent the primary operation (issue creation) from succeeding. The recommended fix is straightforward: treat agent assignment as an optional enhancement rather than a required step.

System Status: ✅ HEALTHY

Key Takeaways:

1. Core safe output operations (create_issue, create_pr, create_discussion) are working reliably
2. Permission errors should be handled more gracefully
3. No critical bugs or systemic issues detected
4. The system is ready for continued production use
