# AGENTS.md

## Project
One paragraph: what this repository does and who uses it.

## Commands
- Install: `pnpm install`
- Dev server: `pnpm dev`
- Tests: `pnpm test` (run before you finish)
- Lint and types: `pnpm lint && pnpm typecheck`

## Layout
- `src/app/`: routes and pages
- `src/lib/`: shared logic, no UI code
- `tests/`: mirrors `src/`

## Conventions
- TypeScript strict mode; avoid `any`.
- Follow the patterns already in `src/` before adding new ones.
- Small, focused functions; name things for what they do.

## Boundaries
- Never read or edit `.env*` files or commit secrets.
- Ask before adding a dependency or changing a public API.

## Done means
Tests pass, lint is clean, and the change is explained in the PR description.
