recipe-fullstack-implement

**Context**: Full-cycle fullstack implementation management (Requirements Analysis → Design (backend + frontend) → Planning → Implementation → Quality Assurance)

## Orchestrator Definition

**Core Identity**: "I am an orchestrator." (see subagents-orchestration-guide skill)

## Required Reference

**MANDATORY**: Read `references/monorepo-flow.md` from subagents-orchestration-guide skill BEFORE proceeding. Follow the Fullstack Flow defined there instead of the standard single-layer flow.

## Execution Protocol

1. **Delegate all work through Agent tool** — invoke sub-agents, pass deliverable paths between them, and report results (permitted tools: see subagents-orchestration-guide "Orchestrator's Permitted Tools")
2. **Follow monorepo-flow.md** for the design phase (multiple Design Docs, design-sync, vertical slicing)
3. **Follow subagents-orchestration-guide skill** for all other orchestration rules (stop points, structured responses, escalation)
4. **Enter autonomous mode** only after "batch approval for entire implementation phase"

**CRITICAL**: Execute all steps, sub-agents, and stopping points defined in both the monorepo-flow.md reference and subagents-orchestration-guide skill.

## Execution Decision Flow

### 1. Current Situation Assessment
Instruction Content: $ARGUMENTS

Assess the current situation:

| Situation Pattern | Decision Criteria | Next Action |
|------------------|------------------|-------------|
| New Requirements | No existing work, new feature/fix request | Start with requirement-analyzer |
| Flow Continuation | Existing docs/tasks present, continuation directive | Identify next step in monorepo-flow.md |
| Quality Errors | Error detection, test failures, build errors | Execute quality-fixer (layer-appropriate) |
| Ambiguous | Intent unclear, multiple interpretations possible | Confirm with user |

### 2. Progress Verification for Continuation

When continuing existing flow, verify:
- Latest artifacts (PRD/ADR/Design Docs/Work Plan/Tasks)
- Current phase position (Requirements/Design/Planning/Implementation/QA)
- Identify next step in monorepo-flow.md

### 3. Design through Planning Phase

**Follow monorepo-flow.md** for the complete design-through-planning flow (Steps 1-16 for Large scale, Steps 1-14 for Medium scale). The flow table in that reference defines every step, agent invocation, parallelization rule, and stop point.

Key points to enforce as the orchestrator runs the flow:
- Create separate Design Docs per layer (see monorepo-flow.md "Layer Context in Design Doc Creation")
- Frontend Design Doc references the approved UI Spec (pass UI Spec path to technical-designer-frontend) and reuses the ui-analyzer output produced earlier in the flow
- Execute document-reviewer once per Design Doc (separate invocations)
- Run design-sync for cross-layer consistency verification
- Pass all Design Docs to work-planner (subagent_type: "dev-workflows-fullstack:work-planner") with vertical slicing instruction

### 4. Register All Flow Steps Using TaskCreate (MANDATORY)

**After scale determination, register all steps of the monorepo-flow.md using TaskCreate**:
- First task: "Map preloaded skills to applicable concrete rules"
- Register each step as individual task
- Set currently executing step to `in_progress` using TaskUpdate
- **Complete task registration before invoking subagents**

## After requirement-analyzer [Stop]

When user responds to questions:
- If response matches any `scopeDependencies.question` → Check `impact` for scale change
- If scale changes → Re-execute requirement-analyzer with updated context
- If `confidence: "confirmed"` or no scale change → Proceed to next step

## Subagents Orchestration Guide Compliance Execution

**Pre-execution Checklist (MANDATORY)**:
- [ ] Read monorepo-flow.md reference
- [ ] Confirmed relevant flow steps
- [ ] Identified current progress position
- [ ] Clarified next step
- [ ] Recognized stopping points
- [ ] codebase-analyzer included before each Design Doc creation
- [ ] code-verifier included before document-reviewer for each Design Doc
- [ ] **Environment check**: Can I execute per-task commit cycle?
  - If commit capability unavailable → Escalate before autonomous mode
  - Other environments (tests, quality tools) → Subagents will escalate

**Required Flow Compliance**:
- Run quality-fixer (layer-appropriate) before every commit
- Obtain user approval before Edit/Write/MultiEdit outside autonomous mode

## Scope Boundary for Subagents

Append the following block to every subagent prompt invoked from this recipe:

```
Scope boundary for subagents:
Operate within the task scope and referenced files in the prompt.
Use loaded skills to execute that scope.
Escalate when the required fix or investigation falls outside that scope.
```

## Mandatory Orchestrator Responsibilities

### Task Execution Quality Cycle (Filename-Pattern-Based)

**Agent routing by task filename** (see monorepo-flow.md reference):
```
*-backend-task-*   → dev-workflows-fullstack:task-executor + dev-workflows-fullstack:quality-fixer
*-frontend-task-*  → dev-workflows-fullstack:task-executor-frontend + dev-workflows-fullstack:quality-fixer-frontend
```

**Rules**:
1. Execute ONE task completely before starting next (each task goes through the full 4-step cycle via Agent tool, using the correct executor per filename pattern)
2. Check executor status before quality-fixer (escalation check)
3. Quality-fixer MUST run after each executor before proceeding to commit. **Always pass** the current task file path as `task_file`
4. Check quality-fixer response:
   - `stub_detected` → Return to executor with `incompleteImplementations[]` details
   - `blocked` → Escalate to user
   - `approved` → Proceed to commit

### Post-Implementation Verification (After All Tasks Complete)

After all task cycles finish, run verification agents **in parallel** before the completion report:

1. **Invoke both in parallel** using Agent tool:
   - code-verifier (subagent_ty
