Python Package License Finder

This skill helps you deterministically find license information for Python packages using a two-step approach: first checking PyPI metadata, then searching the source repository if needed.

Instructions

When a user asks to find the license for a Python package, follow this deterministic process:

Step 1: Check PyPI Metadata

First, attempt to find the license from PyPI using the package inspection script:

./scripts/find_license.py <package_name> [version]

If the script finds a license in the PyPI metadata, stop here and return the license name.

Step 2: Search Git Repository (if PyPI fails)

If no license is found in PyPI metadata, search the package's source repository:

Get the source repository URL from the PyPI metadata (the script will provide it)
Use the shallow-clone skill to clone the repository:
```
Skill: git:shallow-clone
```

Search for LICENSE files in the cloned repository:

find . -iname "license*" -o -iname "copying*" -o -iname "copyright*" | head -10

Read the license file to identify the license type:
```
head -20 <license_file>
```

Step 3: Report Results

License Found: Return the license name (e.g., "MIT License", "Apache-2.0", "GPL-3.0")
License Not Found: Report that the license could not be determined

Usage Examples

Find License for Popular Package

./scripts/find_license.py requests

Expected: Find "Apache-2.0" from PyPI metadata

Find License for Package with Missing PyPI License

./scripts/find_license.py some-package

Expected: Fall back to repository search if PyPI metadata is incomplete

Specific Version Analysis

./scripts/find_license.py django 4.2.0

Expected: Find license for specific Django version

Error Handling

Package Not Found

Verify package name spelling
Check package availability on PyPI
Suggest alternative package names

Repository Access Issues

Report if source repository is unavailable
Note private/restricted repositories
Suggest manual license verification

License File Parsing

Handle non-standard license file formats
Report unclear or multiple licenses
Recommend manual review for complex cases

Integration Notes

This skill complements:

python-packaging:complexity - License info helps assess redistribution complexity
python-packaging:license-checker - Provides license names for compatibility assessment
python-packaging:source-finder - Uses similar PyPI metadata analysis

The skill focuses on finding license information, while license-checker focuses on assessing license compatibility for redistribution.
