# AI Contract

Highest operational contract for every agent session.

## Before coding

MUST read:

1. `.ai/constitution.md`
2. `.ai/architecture.md`
3. `.ai/domain.md` (+ `domain/domain-map.md` when touching models/API)
4. `.ai/coding.md`
5. Task-relevant: `api.md` / `database.md` / `ui.md` / `security.md` / `product/lexicon.md` + `product/feature-map.md`
6. Run/dev tasks: `environment.md` + `development.md`（部署/镜像任务才读 `deployment.md` / `docker.md`）
7. UI tasks: `design/design-system.md` + `design/component-catalog.md` + `design/platform/*`
8. Relevant ADR under `.ai/adr/` if changing stack or style

## After coding

MUST:

1. Run / follow `.ai/review.md` and print Review block
2. Verify `.ai/definition-of-done.md`
3. Use matching checklist under `.ai/checklists/`
4. Prefer verifying with `.ai/commands.md` (build/test/health)

## Never

- Guess API shape
- Guess DB schema
- Guess product requirement
- Invent endpoints, tables, or domain words not in `.ai/domain.md` / OpenAPI / task
- Silently reverse an Accepted ADR
- Default local workflow to full-stack Docker / rebuild app images on every code change

## If unclear

**ASK FIRST.** Do not invent. Do not “assume and continue”.
