Error Clusters

Cluster 1: Missing Artifact - aw.patch Not Found

Error Pattern:

Unable to download artifact(s): Artifact not found for name: aw.patch

Statistics:

• Occurrences: 7 failures
• Affected Operations: missing_tool (5 failures), noop (2 failures)
• Affected Workflows: Tidy workflow only
• Affected Run IDs:
  • §20578651646
  • §20578903832
  • §20579100299
  • §20579491013 (2 operations failed)
  • §20580210061
  • §20582370492

Root Cause Analysis:

This is not a safe output job bug. The issue occurs in the upstream workflow:

1. The Tidy workflow's agent job is supposed to create an aw.patch artifact containing code changes
2. The safe output job attempts to download this artifact to process the results
3. In these 7 cases, the agent job did not create the aw.patch artifact (likely because there were no changes to commit, or the agent encountered errors)
4. The safe output job then fails when trying to download the non-existent artifact

Context from Failed Operations:

The agent was reporting legitimate issues:

• Build toolchain not available (make, go, golangci-lint missing)
• Permission denied errors for filesystem operations
• Environment misconfiguration preventing code tidying tasks

Impact:

• Severity: Medium
• User Impact: Low - These are informational operations (missing_tool and noop)
• System Impact: None - Core safe output operations unaffected
• Workflow Impact: The Tidy workflow cannot complete when tools are missing, which is expected behavior

---

Root Cause Deep Dive

The Artifact Lifecycle Issue

Expected Flow:

Agent Job → Creates aw.patch artifact → Safe Output Job downloads artifact → Processes results

Actual Flow in Failures:

Agent Job → (No artifact created) → Safe Output Job tries to download → ERROR: Artifact not found

Why No Artifact?

From the missing_tool and noop operation data, the agent was encountering:

1. Build Tools Missing:

   • make, go, golangci-lint, npm not available
   • Commands fail with "Permission denied"
   • Cannot run make fmt, make lint, make test, make recompile

2. Filesystem Restrictions:

   • Cannot create directories or files using bash
   • Write operations blocked with "Permission denied"
   • Read operations work normally

3. Environment Issues:

   • Tools show in GOROOT but binaries not accessible
   • Actions like actions/setup-go@v6 may not be running properly

The Real Problem:

The Tidy workflow's environment setup is incomplete or failing, preventing the agent from:

• Running build commands
• Creating code changes
• Generating the aw.patch artifact

When there's no artifact, the safe output job has no graceful handling and simply fails.

Recommendations

Critical Issues (Immediate Action Required)

1. Fix Tidy Workflow Environment Setup

Priority: 🔴 High
Category: Infrastructure / Workflow Configuration
Owner: DevOps / Platform Team

Problem: The Tidy workflow's agent job is running in an environment where build tools are not accessible, preventing it from performing its core function.

Root Cause:

• Build tools (make, go, golangci-lint, npm) are either not installed or not in PATH
• Filesystem write permissions are restricted for the workflow user
• Setup actions may be failing silently or not running at all

Recommended Actions:

1. Verify Setup Steps: Review .github/workflows/tidy.lock.yml to ensure:

   - uses: actions/setup-go@v6
     with:
       go-version: '1.21'  # or appropriate version
   - name: Install build tools
     run: |
       sudo apt-get update
       sudo apt-get install -y make
       go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest

2. Check Runner Configuration: Ensure the workflow is using a properly provisioned GitHub Actions runner

3. Review Permissions: Verify that the workflow user has write permissions to the workspace

4. Add Debugging: Add a debugging step before the agent job:

   - name: Debug environment
     run: |
       echo "PATH: $PATH"
       which go || echo "go not found"
       which make || echo "make not found"
       which golangci-lint || echo "golangci-lint not found"
       go version || echo "go version failed"
       make --version || echo "make version failed"

5. Test Locally: Reproduce the issue locally or in a test workflow to understand the environment constraints

Expected Outcome: Tidy workflow agent can successfully run build commands and create aw.patch artifacts

Success Metric: 100% success rate for Tidy workflow safe output operations

---

2. Improve Artifact Download Error Handling

Priority: 🟡 Medium
Category: Error Handling / Resilience
Owner: Safe Output Job Maintainers

Problem: Safe output jobs fail hard when the aw.patch artifact is missing, with no graceful degradation.

Recommended Actions:

1. Add Conditional Logic: Check if artifact exists before downloading:

   // In safe output job script
   const artifacts = await github.rest.actions.listWorkflowRunArtifacts({
     owner: context.repo.owner,
     repo: context.repo.repo,
     run_id: context.runId
   });
   
   const awPatchArtifact = artifacts.data.artifacts.find(a => a.name === 'aw.patch');
   
   if (!awPatchArtifact) {
     console.log('⚠️  aw.patch artifact not found - agent may have completed without changes');
     // Continue with limited functionality or exit gracefully
     return;
   }
   
   // Proceed with download...

2. Graceful Degradation: When artifact is missing:

   • Log a warning instead of failing
   • Still process any missing_tool or noop messages that don't require the patch
   • Add a comment to the issue/PR explaining the agent completed without changes

3. Better Error Messages: Improve the error message to be more informative:

   ⚠️  Cannot process results: aw.patch artifact not created by agent job.
   This usually means:
   - The agent completed without making changes
   - The agent encountered errors before creating a patch
   Check the agent job logs for details.
   

Expected Outcome: Safe output jobs handle missing artifacts gracefully without failing

Success Metric: Zero safe output job failures due to missing artifacts

---

Bug Fixes Required

No Safe Output Job Bugs Identified

✅ All safe output job logic is working correctly. The failures are entirely due to missing artifacts from upstream jobs, not bugs in the safe output job code itself.

---

Configuration Changes

1. Artifact Creation Policy

Current: Artifacts are only created when the agent makes changes
Recommended: Always create an artifact, even if empty

Implementation:

# In Tidy workflow, agent job
- name: Create artifact (even if empty)
  if: always()  # Run even if previous steps failed
  uses: actions/upload-artifact@v4
  with:
    name: aw.patch
    path: aw.patch
    if-no-files-found: warn  # Don't fail if file doesn't exist

Alternatively:

# Ensure aw.patch always exists
touch aw.patch  # Create empty file if agent made no changes

---

Process Improvements

1. Enhanced Monitoring

Recommendation: Continue daily safe output health audits

Current State: This is the first automated audit, providing baseline metrics

Future Improvements:

• Track trends over time (success rate changes, new error patterns)
• Alert on degradation below 85% success rate
• Monitor individual workflow health separately
• Correlate safe output failures with agent job failures

Implementation: This workflow runs daily and stores results in /tmp/gh-aw/cache-memory/safe-output-health/

---

2. Documentation Updates

Recommendation: Document artifact requirements and error handling

Areas to Document:

1. For Workflow Authors:

   • Requirement to create aw.patch artifact
   • Artifact creation best practices
   • Handling cases where agent makes no changes

2. For Safe Output Job Maintainers:

   • Artifact download patterns
   • Error handling strategies
   • Testing with missing artifacts

3. For Troubleshooters:

   • Common error patterns and their meanings
   • How to diagnose artifact creation failures
   • Relationship between agent job and safe output job failures

Work Item Plans

Work Item 1: Fix Tidy Workflow Environment Setup

Type: Bug Fix
Priority: 🔴 High
Estimated Effort: Medium (2-4 hours)

Description:
The Tidy workflow is failing to provide a properly configured environment for the agent job, resulting in missing build tools and filesystem permission errors. This prevents the agent from performing code tidying tasks and creating the required aw.patch artifact.

Acceptance Criteria:

• Tidy workflow agent job can successfully execute make fmt
• Tidy workflow agent job can successfully execute make lint
• Tidy workflow agent job can successfully execute make test
• Tidy workflow agent job can successfully create aw.patch artifact
• All Tidy workflow safe output operations succeed
• No "Permission denied" errors in Tidy workflow logs
• All required build tools (go, make, golangci-lint, npm) are available in PATH

Technical Approach:

1. Audit Current Configuration:

   • Review .github/workflows/tidy.lock.yml setup steps
   • Check if actions/setup-go is present and configured
   • Verify build tool installation steps

2. Add Missing Setup Steps:

   - uses: actions/setup-go@v6
     with:
       go-version-file: 'go.mod'  # Use version from go.mod
       cache: true
   
   - name: Install build dependencies
     run: |
       sudo apt-get update
       sudo apt-get install -y make
       make install-tools  # If repository has this target

3. Fix Permissions:

   • Ensure runner user has write access to workspace
   • Check if custom user awfuser has appropriate permissions
   • Review any security sandboxing that might block writes

4. Add Environment Validation:

   - name: Validate environment
     run: |
       set -e
       echo "Checking required tools..."
       command -v go
       command -v make
       command -v golangci-lint || echo "⚠️  golangci-lint not found"
       echo "Environment ready ✅"

5. Test Changes:

   • Manually trigger Tidy workflow
   • Verify all build commands execute successfully
   • Confirm aw.patch artifact is created

Dependencies: None

Testing Plan:

1. Create a test branch with a small code formatting issue
2. Trigger Tidy workflow
3. Verify agent successfully formats code
4. Confirm aw.patch artifact is created
5. Verify safe output job succeeds

---

Work Item 2: Graceful Artifact Handling in Safe Output Jobs

Type: Enhancement
Priority: 🟡 Medium
Estimated Effort: Small (1-2 hours)

Description:
Add graceful handling for missing aw.patch artifacts in safe output jobs to prevent job failures when the agent completes without creating a patch (e.g., no changes needed, or agent encountered errors).

Acceptance Criteria:

• Safe output job checks for artifact existence before downloading
• Safe output job logs informative message when artifact is missing
• Safe output job exits successfully when artifact is not found (not as failure)
• missing_tool and noop operations can still be processed without artifact
• Zero safe output job failures due to missing artifacts

Technical Approach:

1. Add Artifact Existence Check:

   // In actions/setup/js/safe_outputs.cjs or equivalent
   
   async function checkArtifactExists(github, context, artifactName) {
     try {
       const artifacts = await github.rest.actions.listWorkflowRunArtifacts({
         owner: context.repo.owner,
         repo: context.repo.repo,
         run_id: context.payload.workflow_run.id
       });
       
       return artifacts.data.artifacts.some(a => a.name === artifactName);
     } catch (error) {
       console.error('Error checking for artifact:', error);
       return false;
     }
   }

2. Conditional Download Logic:

   const artifactExists = await checkArtifactExists(github, context, 'aw.patch');
   
   if (!artifactExists) {
     console.log('⚠️  aw.patch artifact not found');
     console.log('The agent may have completed without changes, or encountered errors.');
     console.log('Processing any non-patch-dependent outputs...');
     
     // Process missing_tool and noop operations that don't need the patch
     await processNoArtifactOutputs(outputs);
     
     return;  // Exit successfully
   }
   
   // Proceed with artifact download...

3. Update Artifact Download Step:

   # In .github/workflows/tidy.lock.yml (safe_outputs job)
   - name: Download artifacts
     uses: actions/download-artifact@v4
     with:
       name: aw.patch
     continue-on-error: true  # Don't fail job if artifact missing
   
   - name: Check artifact availability
     id: check-artifact
     run: |
       if [ -f "aw.patch" ]; then
         echo "artifact_available=true" >> $GITHUB_OUTPUT
       else
         echo "artifact_available=false" >> $GITHUB_OUTPUT
         echo "⚠️  aw.patch not found - agent completed without changes"
       fi
   
   - name: Process outputs
     env:
       ARTIFACT_AVAILABLE: ${{ steps.check-artifact.outputs.artifact_available }}
     run: |
       # Process based on artifact availability

Dependencies: None

Testing Plan:

1. Create a test workflow that intentionally doesn't create aw.patch
2. Trigger safe output job
3. Verify job completes successfully with informative logging
4. Test with missing_tool and noop operations
5. Verify no failures reported

---

Work Item 3: Create Empty Artifact Policy

Type: Process Improvement
Priority: 🟢 Low
Estimated Effort: Small (30 minutes)

Description:
Establish a policy that agent jobs should always create the aw.patch artifact, even if empty, to avoid downstream safe output job failures.

Acceptance Criteria:

• All workflows that use safe output jobs create aw.patch artifact
• Artifact is created even when agent makes no changes
• Artifact upload uses if-no-files-found: warn to handle edge cases
• Documentation updated with artifact creation requirements

Technical Approach:

1. Update Workflow Template:

   # In workflow agent job, after agent completes
   - name: Ensure artifact exists
     if: always()
     run: |
       # Create empty aw.patch if it doesn't exist
       if [ ! -f "aw.patch" ]; then
         echo "No changes from agent, creating empty patch"
         touch aw.patch
       fi
   
   - name: Upload patch artifact
     if: always()
     uses: actions/upload-artifact@v4
     with:
       name: aw.patch
       path: aw.patch
       if-no-files-found: warn

2. Document Policy:

   • Add to workflow authoring guidelines
   • Include in safe output job documentation
   • Add comments in workflow templates

3. Apply to All Workflows:

   • Identify workflows using safe output jobs (check outputs.jsonl usage)
   • Add artifact creation enforcement to each
   • Test each workflow after modification

Dependencies: None
