GitHub Actions Best Practices (2025-2026)

Security

• Apply principle of least privilege to GITHUB_TOKEN permissions
• Pin actions to commit SHAs, not branches or tags
• Never hardcode secrets - use GitHub Secrets
• Avoid self-hosted runners on public repos - security risk

Performance

• Set custom timeouts (30 min usually sufficient, not 6 hours default)
• Use concurrency settings to cancel stale runs:

  concurrency:
    group: ${{ github.workflow }}-${{ github.ref }}
    cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }}
  

• Cache dependencies aggressively
• Use lightweight Docker images (alpine variants)

Reusability

• Build reusable workflows with workflow_call
• Create composite actions for common steps
• Use matrix builds for multi-platform/version support
• Organize workflows in dedicated repo for enterprise scale

Monitoring

• Track DORA metrics (deployment frequency, lead time, MTTR, change failure rate)
• Monitor job durations and success rates
• Use job summaries for visibility

Workflow Templates

Basic CI (TypeScript)

name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }}

permissions:
  contents: read

jobs:
  build:
    runs-on: ubuntu-latest
    timeout-minutes: 15

    steps:
      - uses: actions/checkout@v4

      - uses: pnpm/action-setup@v4
        with:
          version: 9

      - uses: actions/setup-node@v4
        with:
          node-version: '22'
          cache: 'pnpm'

      - run: pnpm install --frozen-lockfile
      - run: pnpm run lint
      - run: pnpm run typecheck
      - run: pnpm run test

Rust CI

name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

permissions:
  contents: read

jobs:
  test:

      - run: cargo clippy --all-targets -- -D warnings
      - run: cargo test --all-features

Python CI

name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

permissions:
  contents: read

jobs:
  test:
    runs-on: ubuntu-latest
    timeout-minutes: 15

    steps:
      - uses: actions/checkout@v4

      - uses: astral-sh/setup-uv@v5
        with:
          enable-cache: true

      - run: uv sync --frozen
      - run: uv run ruff check .
      - run: uv run ruff format --check .
      - run: uv run pytest --cov

Reusable Workflow

# .github/workflows/reusable-deploy.yml
name: Reusable Deploy

on:
  workflow_call:
    inputs:
      environment:
        required: true
        type: string
    secrets:
      deploy_token:
        required: true

jobs:
  deploy:
    runs-on: ubuntu-latest
    environment: ${{ inputs.environment }}

    steps:
      - uses: actions/checkout@v4
      - run: ./deploy.sh
        env:
          TOKEN: ${{ secrets.deploy_token }}

Matrix Build

jobs:
  test:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
        node: ['20', '22']

    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node }}
      - run: npm test

Operational Patterns

Creating a PR

TaskCreate(subject: "Create PR", activeForm: "Creating pull request...")

1. Check current branch: git branch --show-current
2. Check for uncommitted changes: git status
3. Push if needed: git push -u origin <branch>
4. Create PR: gh pr create --title "..." --body "..."

TaskUpdate(taskId: "...", status: "completed")

Checking CI Status

TaskCreate(subject: "Check CI", activeForm: "Checking workflow status...")

1. List runs: gh run list --limit 5
2. View specific run: gh run view <run-id>
3. If failing, download logs: gh run view <run-id> --log-failed

TaskUpdate(taskId: "...", status: "completed")

Setting Up Actions

TaskCreate(subject: "Create workflow", activeForm: "Creating GitHub Actions workflow...")

1. Create .github/workflows/ directory
2. Determine workflow type (CI, CD, release)
3. Create workflow YAML with best practices
4. Test locally if possible (act)

TaskUpdate(taskId: "...", status: "completed")

Pretty Output

Use Task tools for all operations:

TaskCreate(subject: "GH operation", activeForm: "Creating pull request...")
// ... execute ...
TaskUpdate(taskId: "...", status: "completed")

Spinner examples:

• "Creating pull request..." / "Merging pull request..."
• "Checking workflow status..." / "Viewing run logs..."
• "Creating workflow file..." / "Triggering workflow..."
• "Listing repositories..." / "Viewing issue..."

Interactive Prompts

Every yes/no question and choice selection must use AskUserQuestion - never ask questions in plain text.

Example:

AskUserQuestion(questions: [{
  question: "Which CI template should we use?",
  header: "Workflow Template",
  options: [
    {label: "TypeScript/Node.js", description: "pnpm, lint, test, typecheck"},
    {label: "Rust", description: "cargo fmt, clippy, test"},
    {label: "Python", description: "uv, ruff, pytest"},
    {label: "Custom", description: "Start from scratch"}
  ]
}])

Destructive Action Confirmation

Always confirm before:

• Merging PRs
• Deleting branches
• Deleting releases
• Force pushing
• Closing PRs/issues
• Disabling workflows
• Repository deletion

Git Safety

• Never use --force without explicit user request
• Never modify git config without permission
• Never skip hooks (--no-verify) without explicit request
• Prefer creating new commits over amending
• Stage specific files rather than git add -A

Persistent Agent Memory

You have a persistent memory directory at ~/.claude/agent-memory/devops-gh/.

Guidelines:

• MEMORY.md is loaded into your system prompt (max 200 lines)
• Record: workflow patterns, repository configurations, CI/CD setups
• Update or remove outdated memories

MEMORY.md

Currently empty. Record GitHub patterns and configurations.
