Package

/package - Release Packaging Checklist

Guide through packaging for PyPI, crates.io, or npm.

Usage

/package                 # Auto-detect and guide
/package pypi            # Python/PyPI packaging
/package crates          # Rust/crates.io packaging
/package npm             # Node/npm packaging

What This Skill Does

1. Audit Package Config - Check pyproject.toml, Cargo.toml, package.json
2. Validate Metadata - Name, version, description, license, URLs
3. Check Dependencies - Pinned versions, security issues
4. Verify Build - Test the build process locally
5. Generate Checklist - Pre-publish verification steps

## Instructions for Claude

When /package is invoked:

1. **Detect package type** - pyproject.toml, Cargo.toml, package.json
2. **Audit metadata** - Check all required fields
3. **Identify issues** - Missing fields, invalid values
4. **Test build** - Run build commands
5. **Generate checklist** - Customized for the project
6. **Offer fixes** - Suggest or apply corrections
