git-agent for JavaScript

LLM-powered conventional commits for JavaScript projects

From Express APIs to vanilla browser scripts, git-agent reads your JavaScript diffs and produces conventional commit messages that accurately capture what changed and why.

diff example

diff --git a/src/middleware/rateLimit.js b/src/middleware/rateLimit.js

 module.exports = rateLimit({
   windowMs: 15 * 60 * 1000,
   max: 100,

 });

git-agent outputfeat(middleware): back rate limiter with Redis and structured 429 response

- replace in-memory store with RedisStore for multi-instance consistency
- upgrade standardHeaders to draft-7 format
- return machine-readable JSON body with retryAfter field on 429

In-memory rate limiting was reset on every dyno restart and did not
share state across instances; Redis store ensures limits are enforced
cluster-wide.

Why it works for JavaScript

Works with CommonJS (require) and ESM (import) projects equally well
Understands Express, Fastify, and Koa middleware patterns
Detects package.json changes and separates dependency bumps into chore commits
Handles bundler configs (webpack, rollup, esbuild) as distinct chore commits

install

brew install gitagenthq/tap/git-agent
# inside your JS repo
git-agent init   # scans package.json workspaces for scope suggestions

FAQ

Does git-agent work with npm, yarn, and pnpm projects?

Yes. git-agent is package-manager agnostic. It reads diffs regardless of which lockfile format you use.

How does git-agent handle minified or generated JavaScript files?

Add generated files to .gitignore. git-agent commits only what is staged, and git-agent init generates a .gitignore entry for common build output directories.

Can git-agent split a large JavaScript refactor into multiple commits?

Yes. Atomic commit splitting is git-agent's core differentiator. It plans commit groups from the diff before writing any commit, then stages and commits each group independently.
