🏥 Safe Output Health Report - February 18, 2026

[github-actions[bot]]

Executive Summary

• Period: Last 24 hours (February 17-18, 2026)
• Runs Analyzed: 38
• Workflows Active: 17
• Safe Output Jobs Executed: 33
• Safe Output Jobs Failed: 1 (actually a post-processing failure)
• Actual Safe Output Success Rate: 96.97% (32/33, excluding skipped jobs)
• Overall Success Rate: 87.88% (29/33, including skipped)

Key Finding

The single "failure" recorded is not a safe output job failure. The Duplicate Code Detector workflow successfully created an issue, but a subsequent step to assign Copilot to the issue failed due to insufficient GitHub token permissions. This is a post-processing failure, not a safe output failure.

Health Status: ✅ EXCELLENT

Safe output jobs are performing exceptionally well with only 1 post-processing permission issue and 3 skipped jobs out of 33 total executions.

Safe Output Job Statistics

Job Type	Total Executions	Failures	Skipped	Success Rate
safe_outputs	33	1*	3	87.88%

*The 1 failure is actually a post-processing step, not the safe output job itself. True safe output success rate: 96.97% (32/33 excluding skipped).

Execution Duration

• Average Duration: 16.0 seconds
• Range: 7-44 seconds
• Fastest Workflows: Auto-Triage Issues (7s), Agent Container Smoke Test (8s)
• Slowest Workflows: Smoke Project (44s), Changeset Generator (34s)

Error Analysis

Single "Failure" - Post-Processing Permission Error

Run: §22125968544
Workflow: Duplicate Code Detector
Job: Step 7 - "Assign Copilot to created issues" (post-safe-output)

What Happened

1. ✅ Safe output job succeeded: Issue Duplicate Code: Expired Entity Cleanup Flows (Issues/PRs/Discussions) #16510 was successfully created
2. ✅ Issue content was correct: Title, body, labels all populated correctly
3. ❌ Post-processing step failed: Attempted to assign Copilot to the newly created issue
4. ❌ Permission denied: GraphQL mutation replaceActorsForAssignable returned FORBIDDEN

Error Details

View GraphQL error

{
  "errors": [
    {
      "type": "FORBIDDEN",
      "path": ["replaceActorsForAssignable"],
      "message": "Could not assign agent: target repository is not writable."
    }
  ]
}

Root Cause: The GITHUB_TOKEN used by the workflow has contents: read and issues: write permissions, but lacks the additional permissions required to assign Copilot agents to issues via the GraphQL API.

Impact

• Safe Output Health: ✅ No impact - safe output job worked correctly
• User Experience: ⚠️ Minor - Issue was created but Copilot wasn't auto-assigned
• Workflow Completion: ❌ Workflow marked as failed despite successful issue creation

Root Cause Analysis

Classification: Post-Processing Failure

This is NOT a safe output job failure. The safe output system performed correctly:

1. ✅ Read agent output from artifact
2. ✅ Parsed create_issue instruction
3. ✅ Validated issue schema
4. ✅ Created issue via GitHub API
5. ✅ Issue appeared in repository (Duplicate Code: Expired Entity Cleanup Flows (Issues/PRs/Discussions) #16510)

The failure occurred in a subsequent workflow step that attempted to enhance the created issue by assigning Copilot.

Why This Matters for Monitoring

This distinction is critical for accurate health monitoring:

• Safe Output Health: 100% success rate for actual output processing
• Workflow Health: 96.97% success rate (including post-processing)
• False Positive: Counting this as a "safe output failure" misrepresents system health

Token Permission Analysis

Current GITHUB_TOKEN permissions:

• ✅ contents: read - Can read repository files
• ✅ issues: write - Can create, edit, comment on issues
• ❌ Missing: Additional GraphQL permission for replaceActorsForAssignable

Recommendations

1. Differentiate Safe Output from Post-Processing [Priority: Medium]

Problem: Current monitoring conflates safe output job health with post-processing step health.

Recommendation: Update monitoring dashboards and alerts to distinguish:

• Safe Output Job Failures: Failures in processing agent output (create_issue, add_comment, etc.)
• Post-Processing Failures: Failures in enhancement steps (assign agents, add reactions, etc.)

Implementation:

• Add labels to job steps indicating which phase they belong to
• Create separate health metrics for each phase
• Update alert thresholds accordingly

Estimated Effort: Small (2-4 hours)

2. Fix Copilot Assignment Permission [Priority: Low]

Problem: Workflow attempts to assign Copilot but lacks required permissions.

Options:

Option A: Add Required Permissions (Recommended)

• Research the exact permission required for replaceActorsForAssignable
• Add to workflow's permissions: block
• Verify in a test run

Option B: Make Assignment Optional

• Wrap assignment step in try-catch
• Continue workflow even if assignment fails
• Log warning instead of error

Option C: Remove Assignment Step

• Remove the Copilot assignment entirely
• Users can manually assign if needed

Recommendation: Option B (make optional) - preserves functionality where possible without blocking workflow success.

Estimated Effort: Small (1-2 hours)

3. Improve Error Messages [Priority: Low]

Problem: Permission errors in post-processing steps cause confusing failure states.

Recommendation:

• Add clear error messages explaining what succeeded and what failed
• Include workarounds in error output (e.g., "Issue created successfully at #X, but automatic Copilot assignment failed. Please assign manually.")
• Use workflow status annotations to show partial success

Estimated Effort: Small (2-3 hours)

Historical Context

This is the first safe output health audit, so no historical data is available for trend analysis. Future audits will track:

• Success rate trends over time
• Error pattern evolution
• Performance degradation signals
• Workflow reliability changes

Metrics and KPIs

Overall Safe Output Success Rate

• Actual (excluding post-processing): 96.97% ✅
• Reported (including post-processing): 87.88% ⚠️

Most Reliable Workflows (5+ executions)

1. AI Moderator: 6/6 successful (100%)
2. Auto-Triage Issues: 5/5 successful (100%)

Average Performance

• Execution Time: 16.0 seconds (excellent)
• Failure Rate: 3.03% (1/33, excellent)
• Skip Rate: 9.09% (3/33, expected for conditional workflows)

Job Type Distribution

• create_issue: Most common safe output type
• add_comment: Frequently used for triage workflows
• create_discussion: Used in reporting workflows
• noop: Used when no action needed (transparency logs)

Next Steps

• Update monitoring to distinguish safe output vs. post-processing failures
• Investigate exact permission needed for Copilot assignment
• Implement error handling for optional post-processing steps
• Schedule next audit for February 19, 2026
• Build trending dashboard with historical data

Conclusion

Safe output job health is excellent. The system is performing reliably with a 96.97% true success rate. The single "failure" is actually a post-processing permission issue that occurred after successful issue creation.

Key Takeaways

1. ✅ Safe output processing is working correctly
2. ✅ No bugs or systematic failures detected
3. ⚠️ Post-processing steps need better error handling
4. ⚠️ Monitoring needs to separate safe output health from post-processing health
5. ✅ Average execution time (16s) is fast and consistent
