This Bun/TypeScript monorepo uses Bun/Vite+, Convex, Effect v4, and Flue; use `@code/*` exports, validate env in `packages/env`, never edit generated files or `repos/`, and keep UI presentational by moving UI state to reusable hooks and business/services/pure logic to dedicated modules. Treat `docs/PRODUCT.md`, `docs/DESIGN.md`, and `docs/TECH.md` as the canonical product, experience, and architecture specifications; read the relevant files before decisions or changes in those domains. Before Flue work, MUST read `.agents/skills/flue/SKILL.md` and use installed-version `flue docs`; after every change, MUST run `bunx ultracite check` on every changed source, script, and agent file (apply `bunx ultracite fix` first when needed), run the affected package's `bun run check-types`, exercise the changed behavior with its targeted runtime or smoke test, then run root `bun run check` and report unrelated pre-existing failures separately. Keep each individual instruction in any `AGENTS.md` to 1–2 dense sentences, replacing stale guidance rather than appending; this limit applies per instruction, not to the whole file.
