GitHub Expert
Overview
Transform into a GitHub expert with comprehensive knowledge of GitHub Actions, CI/CD workflows, repository automation, and development best practices. This skill provides everything needed to set up robust CI/CD pipelines, automate repository management, and implement GitHub workflows efficiently.
Core Capabilities
1. GitHub Actions & CI/CD Workflows
Create and manage GitHub Actions workflows for continuous integration and deployment.
Script: scripts/create_workflow.py
Generate production-ready workflow files for common scenarios:
Static lint with actionlint: When adding or changing workflow files, run actionlint to catch syntax errors, expression type issues, action input mismatches, and security issues (e.g. script injection, hard-coded secrets). Run actionlint in the repo root or add a pre-commit hook for .github/workflows/*.yml. Install via go install github.com/rhysd/actionlint/cmd/actionlint@latest, Homebrew, or pre-commit.
Local validation with act: Before pushing new or changed workflows, run them locally when possible. CI/validation-only (lint, type-check, build, tests; no deploy, no external writes): run act (e.g. act push or act pull_request) before pushing. Effectful (deploy, release): use act -n to dry-run syntax/job order, or add guards (e.g. env var or if: github.run_id) so effectful steps skip under act. Run actionlint first (static), then act (runtime).
2. Repository Automation
Automate repository management with Dependabot and CodeQL.
Generates formatted release notes from git history:
# Generate notes between tags
./scripts/generate_release_notes.sh v1.0.0 v1.1.0
# Generate notes from last tag to HEAD
./scripts/generate_release_notes.sh
# Save to file
./scripts/generate_release_notes.sh > notes.md
# Create GitHub release
gh release create v1.1.0 --notes-file notes.md
Features:
Categorizes commits (features, fixes, docs, etc.)
Lists contributors
Shows statistics
Conventional commit support
When to use:
Creating releases
Publishing changelogs
Documenting version changes
Communicating updates
Workflow Examples
Example 1: "Set up CI/CD for my Node.js project"
Generate CI workflow:
python scripts/create_workflow.py ci --type nodejs-ci
