GitHub Workflow Auto-Fix

Automated CI failure analysis and remediation using Claude Code Action.

When to Use This Skill

Use this skill when...	Use something else when...
Setting up auto-fix workflow for a repo	Fixing a single PR's checks (/git:fix-pr)
Customizing which workflows trigger auto-fix	Inspecting workflow runs manually (/workflow:inspect)
Understanding the auto-fix pattern	Writing new workflows from scratch (/workflow:dev)

Context

• Workflow exists: !find .github/workflows -maxdepth 1 -name 'github-workflow-auto-fix.yml'
• Current workflows: !find .github/workflows -maxdepth 1 -name '*.yml' -type f
• Claude secrets configured: !gh secret list

Parameters

Parse from $ARGUMENTS:

• --setup: Create or update the auto-fix workflow in .github/workflows/
• --workflows <names>: Comma-separated workflow names to monitor (default: auto-detect CI workflows)
• --dry-run: Show what would be created without writing files

Execution

Execute this workflow setup process:

Step 1: Assess current state

1. Check if .github/workflows/github-workflow-auto-fix.yml already exists
2. List all current workflow files and their name: fields
3. Check if CLAUDE_CODE_OAUTH_TOKEN secret is configured

Step 2: Select workflows to monitor

If --workflows provided, use those. Otherwise, auto-detect suitable workflows:

Good candidates for auto-fix monitoring:

• CI/test workflows (lint, test, build, type-check)
• Code quality checks (formatting, style)
• Config validation workflows

Skip these (not suitable for auto-fix):

• Release workflows (release-please, deploy)
• Claude-powered workflows (avoid recursive triggers)
• Scheduled audit workflows
• Reusable workflow definitions

Step 3: Generate workflow file

If --setup or workflow is missing, create .github/workflows/github-workflow-auto-fix.yml:

name: Auto-fix Workflow Failures

on:
  workflow_run:
    workflows:
      # List monitored workflows here
      - "CI"
      - "Lint"
    types: [completed]

concurrency:
  group: auto-fix-${{ github.event.workflow_run.head_branch }}
  cancel-in-progress: false

  pull-requests: write

  actions: read
  id-token: write

  auto-fix:
    if: >-
      github.event.workflow_run.conclusion == 'failure' &&
      github.event.workflow_run.actor.type != 'Bot' &&

      github.event.workflow_run.head_branch != 'master'
    runs-on: ubuntu-latest

          fetch-depth: 0

      - name: Gather failure context
        id: context
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          RUN_ID="${{ github.event.workflow_run.id }}"
          gh run view "$RUN_ID" --log-failed 2>&1 | tail -500 > .auto-fix-failed-logs.txt
          gh run view "$RUN_ID" --json conclusion,status,name,headBranch,headSha,jobs > .auto-fix-run-summary.json
          PR_NUMBER=$(gh pr list --head "${{ github.event.workflow_run.head_branch }}" --json number --jq '.[0].number' 2>/dev/null || echo "")
          echo "pr_number=$PR_NUMBER" >> "$GITHUB_OUTPUT"
          echo "run_id=$RUN_ID" >> "$GITHUB_OUTPUT"
          RECENT_FIX=$(git log --oneline -5 --format='%s' | grep -c 'fix:.*resolve CI failure' || true)
          echo "recent_fix_count=$RECENT_FIX" >> "$GITHUB_OUTPUT"

      - name: Skip if already attempted
        if: steps.context.outputs.recent_fix_count != '0'
        run: echo "::notice::Skipping - recent auto-fix commit exists"

      - name: Analyze and fix with Claude
        if: steps.context.outputs.recent_fix_count == '0'
        uses: anthropics/claude-code-action@v1
        with:
          claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
          direct_prompt: |
            <analysis-and-fix-prompt>
          additional_permissions: |
            Read

            Glob
            Bash(git *)
            Bash(gh *)

Step 4: Validate and report

1. Verify the workflow YAML is valid
2. List the monitored workflows
3. Check that required secrets exist
4. Report any missing prerequisites

Safety Guards

Guard	Purpose
actor.type != 'Bot'	Prevent bot-triggered loops
head_branch != 'main'	Never auto-fix main branch directly
Recent fix check	Skip if auto-fix already attempted
Concurrency group	One auto-fix per branch at a time
max-turns 30	Limit Claude's iteration count

Prerequisites

Requirement	How to set up
CLAUDE_CODE_OAUTH_TOKEN	Repository secret with Claude Code OAuth token
contents: write permission	Included in workflow permissions
pull-requests: write permission	Included in workflow permissions
issues: write permission	For creating issues on complex failures

Agentic Optimizations

Context	Command
Check recent failures	gh run list --status failure --json name,headBranch,conclusion -L 10
Get failed logs	gh run view <id> --log-failed | tail -500
Run summary	gh run view <id> --json conclusion,status,jobs
Find associated PR	gh pr list --head <branch> --json number --jq '.[0].number'
List workflow names	grep -h '^name:' .github/workflows/*.yml
