Contributing to pi

Contributing to pi

Thanks for wanting to contribute! This guide exists to save both of us time.

The One Rule

**You must understand your code.** If you can't explain what your changes do and how they interact with the rest of the system, your PR will be closed.

Using AI to write code is fine. You can gain understanding by interrogating an agent with access to the codebase until you grasp all edge cases and effects of your changes. What's not fine is submitting agent-generated slop without that understanding.

If you use an agent, run it from the `pi-mono` root directory so it picks up `AGENTS.md` automatically. Your agent must follow the rules and guidelines in that file.

First-Time Contributors

We use an approval gate for new contributors:

undefined

This exists because AI makes it trivial to generate plausible-looking but low-quality contributions. The issue step lets us filter early.

Before Submitting a PR

npm run check  # must pass with no errors
./test.sh      # must pass

Do not edit `CHANGELOG.md`. Changelog entries are added by maintainers.

If you're adding a new provider to `packages/ai`, see `AGENTS.md` for required tests.

Philosophy

pi's core is minimal. If your feature doesn't belong in the core, it should be an extension. PRs that bloat the core will likely be rejected.
