-- `infra/`: Infrastructure and operations (Docker, scripts, deployment).

-- `apps/`: Flutter mobile app.
-- `docs/`: Documentation and design/planning artifacts.
+This file serves as the entry point for project development, directing to appropriate constraint files based on development context.

 ## Rules Hierarchy
 
-- This root `AGENTS.md` defines global rules and applies to all changes.
-- When editing `backend/`, you must also follow `backend/AGENTS.md`.
-- When editing `apps/`, you must also follow `apps/AGENTS.md`.
+Follow this hierarchy when developing:
 
-## Docker Startup
-
-Always start services with the env file:
-
-```bash
-docker compose --env-file .env -f infra/docker/docker-compose.yml up -d
+```
+~/.config/opencode/AGENTS.md          # Global core rules (skills, agents, process)
+├── This file (root AGENTS.md)        # Project-level entry
+│   ├── backend/AGENTS.md              # Backend-specific rules

 ```
 
-## Git Branch and Worktree Policy
+## Development Guidance
 
-- Use `dev` as the default base branch for day-to-day development.
-- New development worktrees must be created from `dev` (never from `main`).
-- Do not develop or commit directly on `main` outside explicit release/merge workflows.
-- Do not rewrite `main` history unless explicitly requested (including reset and force push).
+| Development Context | Follow Rules |
+|--------------------|--------------|
+| Backend Python dev | [backend/AGENTS.md](backend/AGENTS.md) |
+| Flutter mobile dev | [apps/AGENTS.md](apps/AGENTS.md) |
+| Infrastructure/ops | This file + infra/ directory conventions |
+| API doc changes | Sync to `docs/runtime/runtime-route.md` |
 
-## API Route Documentation
+## Git Workflow
 
-When modifying HTTP routes (adding, updating, or removing endpoints):
-
-- Sync changes to `docs/runtime/runtime-route.md`
-- Include: HTTP method, path, request/response schema, status codes, error format
-- Keep documentation in sync with actual implementation
+- Default branch: `dev`
+- Feature development: use worktree `git worktree add -b feature/xxx ../feature-xxx dev`
+- Never develop directly on `main`
