"fix stuff" and "wip" pile up in the history until a <code>git blame</code> six months later leaves you guessing.</p> <p>That's why I built <strong>commit-sage</strong>.</p> <h2> What it is </h2> <p>commit-sage is a Python CLI that reads your staged git diff, sends it to an AI provider, and returns a ready-to-use Conventional Commit message — no manual writing.</p> <p>Flow:</p> <ul> <li>Reads staged diff via git</li> <li>Sends diff to configured AI provider (OpenAI or Gemini)</li> <li>Parses response into Conventional Commit format</li> <li>You review before committing</li> </ul> <p>Handles edge cases cleanly: missing API key, no staged files, API failures — all caught with clear error messages instead of crashes.</p> <h2> How it was built </h2> <p>Entire build used free AI-assisted coding tools, zero paid tooling. Started as a single-provider script, refactored into a dispatch pattern once a second backend was added.</p> <h2> Why it matters </h2> <p>Commit history is documentation. A clean log makes changelogs, code review, and debugging easier. commit-sage doesn't replace judgment — it still shows the message before commit — it just removes the blank-page problem.</p> <h2> Try it </h2> <p>MVP stage, feedback and PRs welcome.</p> <p>👉 <a href="https://github.com/monobuildstudio/commit-sage" rel="noopener noreferrer">https://github.com/monobuildstudio/commit-sage</a></p> python git ai opensource
