description: "Universal release workflow: detect project type, init versioning if needed, run tests, bump version, tag, push, and create GitHub release. Works with Python, Go, Node.js, Rust, Java, .NET, Ruby, PHP, and multi-language projects."

Release Runbook

A universal release workflow that adapts to any project type. Supports single-language projects (Python, Go, Node.js, Rust, Java, .NET, Ruby, PHP) and multi-language polyglot projects.

Quick Start

# Fully automated release with specific version
~/.claude/skills/release-runbook/scripts/release.sh --version 1.2.3

# Interactive mode (prompts for version and type)
~/.claude/skills/release-runbook/scripts/release.sh --interactive

# Dry run to see what would happen
~/.claude/skills/release-runbook/scripts/release.sh --dry-run --version 1.2.3

# Just detect project type and version files
~/.claude/skills/release-runbook/scripts/detect-project.sh

# Initialize versioning for a project that lacks it
~/.claude/skills/release-runbook/scripts/init-versioning.sh --version 0.1.0

Preflight Checklist

Before releasing, ensure:

• [ ] Clean git state: No uncommitted changes (or stash them)
• [ ] On correct branch: Usually main or master
• [ ] GitHub CLI installed: gh authenticated with gh auth status
• [ ] Remote configured: git remote -v shows the origin
• [ ] Build tools installed: Language-specific toolchains (python, go, node, cargo, etc.)
• [ ] Tests passing: Run tests manually first or let the script do it

Workflow Steps

1. Detect Project

The skill automatically detects:

• Languages: Python, Go, Node.js, Rust, Java, .NET, Ruby, PHP
• Version files: package.json, pyproject.toml, Cargo.toml, go.mod, VERSION, etc.
• Build system: Makefile, npm scripts, Go build, Cargo, Maven, Gradle, etc.
• Test commands: pytest, go test, npm test, cargo test, etc.
• Package managers: pip, npm, cargo, brew, etc.

~/.claude/skills/release-runbook/scripts/detect-project.sh

Outputs JSON-like:

PROJECT_TYPE=multi
LANGUAGES=python,go
VERSION_FILES=pyproject.toml,VERSION,go.mod
TEST_COMMAND=make test
BUILD_COMMAND=make build

2. Initialize Versioning (If Needed)

If the project has no versioning:

~/.claude/skills/release-runbook/scripts/init-versioning.sh --version 0.1.0

This will:
- Detect the project type
- Create appropriate version file(s)
- Set up SemVer-compliant version format
- Add --version flag handling if missing

3. Bump Version

Version bumping strategies by ecosystem:

SemVer Guidelines (https://semver.org/):
- MAJOR (1.0.0 → 2.0.0): Incompatible API changes
- MINOR (1.0.0 → 1.1.0): New features, backward compatible
- PATCH (1.0.0 → 1.0.1): Bug fixes, backward compatible

4. Run Tests

The script auto-discovers and runs tests:

# Priority order:
1. Makefile `test` target
2. package.json `test` script
3. pytest (Python)
4. go test ./... (Go)
5. npm test (Node)
6. cargo test (Rust)
7. mvn test (Java)
8. dotnet test (.NET)
9. rake test (Ruby)

Skip tests with --skip-tests (not recommended).

5. Commit & Tag

Creates a release commit and annotated tag:

git commit -m "chore: release v1.2.3"
git tag -a v1.2.3 -m "Release v1.2.3"

The tag format is always v{VERSION}.

6. Push

Pushes commit and tag to remote:

git push origin main
git push origin v1.2.3

7. Build Binaries (If Applicable)

For projects that produce binary artifacts (Go, Rust, .NET, etc.):

# Build for common platforms
make build  # or: go build, cargo build --release, dotnet publish

# Check output directory
ls -la dist/ bin/

Common binary locations by ecosystem:
- Go: dist/, bin/, or build/
- Rust: target/release/
- Node: dist/ or out/
- .NET: bin/Release/

8. GitHub Release

Creates a GitHub release with binaries and auto-generated notes:

# Basic release (no binaries)
gh release create v1.2.3 \
  --title "v1.2.3" \
  --notes "Release notes here..."

# Release with binaries
gh release create v1.2.3 \
  --title "v1.2.3" \
  --notes "Release notes here..." \
  dist/binary-linux-amd64 \
  dist/binary-darwin-amd64 \
  dist/binary-windows-amd64.exe

The release notes include:
- Version number
- Git commit reference
- Links to commits since last tag
- Installation instructions (if detectable)
- Binary download links (if binaries attached)

9. Downstream Artifacts

Updates package registries when applicable:

• npm: npm publish (if package.json has publishConfig)
• Homebrew: Formula update (if detected)
• PyPI: twine upload (if pyproject.toml has configured)
• crates.io: cargo publish (if Cargo.toml has configured)

Advanced Usage

Multi-Language Projects

For projects with multiple languages, the script:

1. Detects all language ecosystems present
2. Updates all version files in coordination
3. Runs tests for each language
4. Builds all artifacts
5. Creates a unified release tag

Example (Curator: Python + Go):
- Updates pyproject.toml and VERSION file
- Runs pytest and go test
- Builds Python wheel and Go binary
- Single GitHub release with both artifacts

Custom Test Commands

Override auto-detected tests:

~/.claude/skills/release-runbook/scripts/release.sh \
  --test-command "make test-integration" \
  --version 1.2.3

Release Notes Templates

Place a .release-notes-template.md in your project root:

## What's Changed

* Full changelog at https://github.com/user/repo/compare/v{{OLD}}...v{{NEW}}

## Installation

\`\`\`bash
pip install mypackage=={{NEW}}
\`\`\`

Signing Releases

For GPG signing:

git config --local commit.gpgsign true
git config --local tag.gpgsign true
~/.claude/skills/release-runbook/scripts/release.sh --version 1.2.3

Troubleshooting

Tests Failing

Run tests manually first to debug:

# Auto-detected test command
~/.claude/skills/release-runbook/scripts/detect-project.sh | grep TEST_COMMAND

# Run manually
pytest  # or go test, npm test, etc.

GitHub Release Creation Fails

Check authentication:

gh auth status
gh auth login

Version File Not Detected

Manually specify or add to project-types.md:

~/.claude/skills/release-runbook/scripts/release.sh \
  --version-file VERSION \
  --version 1.2.3

Multi-Language Project Issues

For complex projects, run release steps manually:

# Detect project
~/.claude/skills/release-runbook/scripts/detect-project.sh

# Bump versions manually in all files

# Run tests for each language
pytest
go test ./...

# Commit all version changes
git commit -m "chore: bump version to 1.2.3"

# Create tag
git tag v1.2.3

# Push
git push origin main && git push origin v1.2.3

# Create release
gh release create v1.2.3 --generate-notes
