# OpenHermit Workspace Rules

This file defines baseline collaboration rules for agents working in this repository.

## General

- Prefer small, incremental changes over large rewrites unless the task explicitly requires a redesign.
- Keep behavior changes aligned with the current documented architecture before introducing new abstractions.
- When changing a core flow, update the corresponding docs in `README.md` and `docs/` in the same branch.
- Do not preserve legacy compatibility unless the user explicitly asks for it.

## Code Changes

- Prefer clear module boundaries over oversized files.
- Reuse existing helpers and shared abstractions before introducing new patterns.
- Keep internal state and external state clearly separated.
- Avoid adding hidden fallback paths that make behavior harder to reason about.

## Testing

- Run relevant tests after meaningful code changes.
- For broad refactors or runtime changes, run:
  - `npm run typecheck`
  - `npm test`
- Do not claim a fix is complete if the affected tests were not run.

## Commits

- Use English commit messages.
- Keep commit messages concise and descriptive.
- Prefer the format: `<type>: <summary>`
- Common types:
  - `feat`
  - `fix`
  - `refactor`
  - `test`
  - `docs`
  - `chore`
- Keep unrelated changes in separate commits.
- Commit only after tests relevant to the change pass.

## Database Migrations

- Schema source of truth: `packages/store/src/schema.ts` (drizzle-orm).
- Migrations live at `packages/store/drizzle/` and are applied automatically at gateway boot via `runMigrations()` (tracked in the `drizzle.__drizzle_migrations` table).
- To change schema: edit `schema.ts`, then from `packages/store/`:
  ```
  DATABASE_URL=... npx drizzle-kit generate --name <short_desc>
  ```
  Review the generated SQL, commit `schema.ts` + `drizzle/000N_*.sql` + `drizzle/meta/` together.
- Never apply schema changes by hand-running `psql` against dev/prod. Manual SQL bypasses the migration tracker, so the next boot will try to re-apply and fail. If you must hotfix prod, also insert a matching row into `drizzle.__drizzle_migrations` so the runner stays in sync.
- `drizzle/_legacy/` holds pre-rebaseline SQL for historical reference only — do not edit.

## Docs

- Use relative links in repository markdown files.
- Keep docs aligned with the current implementation, not old plans.
- Maintain one current source of truth instead of parallel versioned docs unless explicitly requested.
