# Improving Python coverage

Move Python test coverage up with tests that are worth keeping

## What this does

Your Python test coverage is lower than you want and you are not sure where to start. This runs the tests with coverage, reads the report, and writes tests aimed at high-value gaps. Reach for it when you want to chip away at coverage a small increment at a time.

### Top 3 things it does for you

- Run the Python tests with coverage
- Find where coverage is thinnest
- Add tests that raise the number

## About Improving Python coverage

Runs Python unit tests with coverage, analyzes the coverage reports, and implements meaningful tests to raise coverage by a small increment.

Use it when you want to improve Python test coverage systematically, with high-value test cases rather than filler.

## Questions

### Is Improving Python coverage safe to install?

AIR scanned this exact version of Improving Python coverage and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit d2b0db3cda85, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/improving-python-coverage.

### How do I install Improving Python coverage?

Open https://airmarket.ai/app/improving-python-coverage on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/streamlit/streamlit/tree/d2b0db3cda85cb286c2de47fa6bdf6df7e49d235/.claude/skills/improving-python-coverage. Install from that link, not the branch.
