What Skill CI Churn does

GitHub Actions cost analyzer & flaky-test detector for pull requests. Measures wasted CI compute, classifies commits as feature vs ci-fix, generates pre-push checks that would have prevented the retry-push churn. One Python file, gh CLI, no config.

**How much GitHub Actions rebuild time did your last PR waste on avoidable lint and test failures?**

Golly, boss — your green build is a magician; `ci-churn` shows the sleeves.

You ship a 3-line fix, then spend the next 20 minutes watching red X's turn green one push at a time. `ci-churn` reads your PR's commit history and GitHub Actions run durations and tells you exactly where that time went — and which local pre-push check would have saved it.

No pip. No npm. No config file. One Python script, `gh` CLI, done.

Quick Start

1. Install and Use as a Skill (Recommended)

`ci-churn` is designed to be installed as an AI agent skill for assistants like Claude Code, Codex, or pi.

Run the installer to locate your agent's skills folder and install `ci-churn` automatically:

bash <(curl -sL https://raw.githubusercontent.com/gaia-research/skill-ci-churn/main/install.sh)

Once installed, invoke it directly within your agent conversation:

/ci-churn

2. Standalone Python Usage (Secondary)

If you are running manually without an agent, download and run the script directly:

# Download the script
curl -sL https://raw.githubusercontent.com/gaia-research/skill-ci-churn/main/ci_churn.py -o ci_churn.py

# Run on any PR
python3 ci_churn.py
