**Core Responsibilities**
- Orchestrate a streamlined 6-step development workflow:
- Orchestrate a streamlined 7-step development workflow (Step 0 + Step 16):
0. Backend selection (user constrained)
1. Requirement clarification through targeted questioning
2. Technical analysis using codeagent
2. Technical analysis using codeagent-wrapper
3. Development documentation generation
4. Parallel development execution
4. Parallel development execution (backend routing per task type)
5. Coverage validation (≥90% requirement)
6. Completion summary
**Workflow Execution**
- **Step 0: Backend Selection [MANDATORY - FIRST ACTION]**
- MUST use AskUserQuestion tool as the FIRST action with multiSelect enabled
- Ask which backends are allowed for this /dev run
- Options (user can select multiple):
- `codex` - Stable, high quality, best cost-performance (default for most tasks)
- `claude` - Fast, lightweight (for quick fixes and config changes)
- `gemini` - UI/UX specialist (for frontend styling and components)
- Store the selected backends as `allowed_backends` set for routing in Step 4
- Special rule: if user selects ONLY `codex`, then ALL subsequent tasks (including UI/quick-fix) MUST use `codex` (no exceptions)
- **Step 1: Requirement Clarification [MANDATORY - DO NOT SKIP]**
- MUST use AskUserQuestion tool as the FIRST action - no exceptions
- MUST use AskUserQuestion tool
- Focus questions on functional boundaries, inputs/outputs, constraints, testing, and required unit-test coverage levels
- Iterate 2-3 rounds until clear; rely on judgment; keep questions concise
- After clarification complete: MUST use TodoWrite to create task tracking list with workflow steps

- **Step 3: Generate Development Documentation**
- invoke agent dev-plan-generator
- When creating `dev-plan.md`, append a dedicated UI task if Step 2 marked `needs_ui: true`
- When creating `dev-plan.md`, ensure every task has `type: default|ui|quick-fix`

- Test commands
- Use AskUserQuestion to confirm with user:
- Question: "Proceed with this development plan?" (if UI work is detected, state that UI tasks will use the gemini backend)

- **Step 4: Parallel Development Execution [CODEAGENT-WRAPPER ONLY - NO DIRECT EDITS]**
- MUST use Bash tool to invoke `codeagent-wrapper --parallel` for ALL code changes
- NEVER use Edit, Write, MultiEdit, or Task tools to modify code directly
- Backend routing (must be deterministic and enforceable):
- Task field: `type: default|ui|quick-fix` (missing → treat as `default`)
- Preferred backend by type:
- `default` → `codex`
- `ui` → `gemini` (enforced when allowed)
- `quick-fix` → `claude`
- If user selected `仅 codex`: all tasks MUST use `codex`
- Otherwise, if preferred backend is not in `allowed_backends`, fallback to the first available backend by priority: `codex` → `claude` → `gemini`
- Build ONE `--parallel` config that includes all tasks in `dev-plan.md` and submit it once via Bash tool:

**Quality Standards**
- Code coverage ≥90%
- 2-5 genuinely parallelizable tasks
- Tasks based on natural functional boundaries (typically 2-5)
- Each task has exactly one `type: default|ui|quick-fix`
- Backend routed by `type`: `default`→codex, `ui`→gemini, `quick-fix`→claude (with allowed_backends fallback)
- Documentation must be minimal yet actionable
- No verbose implementations; only essential code
