Name

Description
"Set up automated CI fixing with Claude Code. Use when adding a workflow that analyzes failures, applies fixes, and files issues; pass --reusable for a multi-repo workflow_call template."

GitHub Workflow Auto-Fix

Automated CI failure analysis and remediation using Claude Code Action.

Two shapes, selected by flag:

| Shape | Flag | Output | Use for | |-------|------|--------|---------| | Single-repo inline (default) | --setup | One self-contained github-workflow-auto-fix.yml | A single repo that owns its auto-fix logic | | Reusable workflow_call | --reusable (+ --caller) | A reusable-ci-autofix.yml definition plus a thin auto-fix.yml caller | Multiple repos invoking one shared template |

When to Use This Skill

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

Context

  • Inline workflow exists: !find . -path '*/.github/workflows/*' -maxdepth 3 -name 'github-workflow-auto-fix.yml'
  • Reusable workflow exists: !find . -path '*/.github/workflows/*' -maxdepth 3 -name 'reusable-ci-autofix.yml' -type f
  • Caller workflow exists: !find . -path '*/.github/workflows/*' -maxdepth 3 -name 'auto-fix.yml' -type f
  • Current workflows: !find . -path '*/.github/workflows/*' -maxdepth 3 -name '*.yml' -type f
  • Claude secrets configured: !gh secret list

Parameters

Parse from $ARGUMENTS:

  • --setup: Create or update the single-repo inline workflow in .github/workflows/github-workflow-auto-fix.yml
  • --reusable: Create or update the reusable workflow_call definition in .github/workflows/reusable-ci-autofix.yml (see Step 5)
  • --caller: Create the thin caller workflow in .github/workflows/auto-fix.yml that invokes the reusable definition (see Step 5)
  • --workflows <names>: Comma-separated workflow names to monitor (default: auto-detect CI workflows)
  • --dry-run: Show what would be created without writing files

Default (no --reusable/--caller) generates the single-repo inline workflow described in Steps 1–4. --reusable/--caller switch to the reusable variant in Step 5.

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.

The workflow's display name follows <Domain>: <Action> (Auto-fix: is the canonical domain for workflow_run-triggered remediation; quote the value because YAML treats : as a key separator). The strings under workflows: must match the display names of the target workflows exactly — update both sides whenever a target's name: changes. See .claude/rules/workflow-naming.md.

name: "Auto-fix: CI failures"

on:
  workflow_run:
    workflows:
      # List monitored workflows by display name (must match their `name:` exactly)
      - "Test: Suite"
      - "Plugin: Lint skills"
    types: [completed]

        run: echo "::notice::Skipping - recent auto-fix commit exists"

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

Step 5: Reusable variant (--reusable / --caller)

When --reusable or --caller is passed, generate the workflow_call shape instead of the single-repo inline workflow. The full templates live in REFERENCE.md.

  1. --reusable — create .github/workflows/reusable-ci-autofix.yml from REFERENCE.md § Reusable Workflow. Customize:
    • auto_fixable_criteria / not_auto_fixable_criteria defaults to match the project's tech stack
    • verification_commands default to match the project's linter/formatter commands
    • max_turns (default: 50)
  2. --caller — create .github/workflows/auto-fix.yml from REFERENCE.md § Caller Workflow. Customize:
    • The monitored workflow name: strings in the workflows: list (display names — must match each target's name: exactly)
    • auto_fixable_criteria / verification_commands overrides for the project's tools
  3. Display-name convention — the caller's name: follows <Domain>: <Action> (Auto-fix: CI failures is canonical; the reusable definition itself uses Reusable: CI auto-fix). Quote values containing colons. See .claude/rules/workflow-naming.md.
  4. Validate both YAML files, list the monitored workflows, and confirm CLAUDE_CODE_OAUTH_TOKEN or ANTHROPIC_API_KEY exists.

The reusable variant adds dedup (max 2 open auto-fix PRs), workflow_dispatch with a pr_number input, and fan-out — see the Architecture and Safety Guards below, and REFERENCE.md for the rationale.

Architecture

Single-repo inline (default):

workflow_run (failure)
        |
        v
  Gather logs & context
        |
        v
  Claude analyzes failure
        |
    +---+---+
    |       |
    v       v
  Fixable  Complex/External
    |       |
    v       v
  Fix &    Open issue
  push     with analysis
    |       |
    v       v
  Comment  Comment on PR
  on PR    linking issue

The reusable variant wraps the same analyze→fix/issue core in a workflow_call definition fronted by a thin caller (workflow_run + workflow_dispatch with fan-out and a dedup gate). See REFERENCE.md § Reusable Workflow and § Cross-Repository Usage for the full templates.

Safety Guards

| Guard | Variant | Purpose | |-------|---------|---------| | actor.type != 'Bot' | both | Prevent bot-triggered loops | | head_branch != 'main' | both | Never auto-fix main branch directly | | Recent fix check / !startsWith(commit, 'fix(auto):') | both | Skip if auto-fix already attempted; prevent recursive loops | | Concurrency group per branch | both | One auto-fix per branch at a time | | max-turns limit | both | Limit Claude's iteration count (inline 30, reusable 50 default) | | Max 2 open auto-fix PRs | reusable | Prevent PR flooding across repos | | timeout-minutes: 30 | reusable | Prevent runaway jobs |

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 |
