| Question | Owner | Expected Resolution Date |
|----------|-------|------------------------|
| | | |

🗂️ Development Artifacts (Triggered on demand)

Flowchart (Mermaid syntax)

When the user says "produce a flowchart," generate a Mermaid flowchart based on User Stories and feature specs:

flowchart TD
    A[User enters] --> B{Logged in?}
    B -- Yes --> C[Show main screen]
    B -- No --> D[Redirect to login]
    C --> E[Complete core action]
    E --> F[Reach Aha Moment]

Include: Main user flow / Key decision branches / Error scenarios

DB Schema (Mermaid ERD syntax)

When the user says "produce a DB schema," generate a Mermaid erDiagram based on the MVP feature scope:

erDiagram
    USER {
        int id PK
        string name
        string email
        datetime created_at
    }
    PRODUCT {
        int id PK
        string name
        int owner_id FK
    }
    USER ||--o{ PRODUCT : "owns"

Include: Main entities / Relationships / Key fields (FKs, index recommendations)

UI Wireframe (HTML wireframe)

When the user says "produce a UI wireframe," output a low-fidelity wireframe in HTML + inline CSS, including:

Core pages (determine page count based on User Stories)
Grayscale color scheme, no brand colors
Annotate each element's functional purpose
Annotate where the Aha Moment occurs

2. CLAUDE.md, Handoff Overview & Tech-Stack Confirmation

Triggered when the user says "start development," "produce a dev handoff package," "set up my project," or "connect to Claude Code." Read this file, consolidate the outputs from the entire product planning process, and generate a development handoff package that can be used directly in the Claude Code CLI.

Environment Constraints & Handoff Strategy

Key fact: Claude Chat / Cowork and Claude Code are separate runtime environments; you cannot launch Claude Code from within Chat.

The handoff strategy is therefore: Produce a structured development handoff package (a set of files) that the user downloads, places in their project folder, and can kick off the entire development workflow with a single prompt in Claude Code.

The handoff method depends on the user's environment:

User Environment	Handoff Method
Claude Chat (Web/App)	Produce a zip file for download; user extracts to project directory then opens Claude Code
Claude Cowork (Desktop)	Same as above, but can write files directly to a user-specified local path
Already in Claude Code	Create all files directly in the project directory (in this scenario, this skill is likely referenced from CLAUDE.md)

Development Handoff Package Contents

Produce the following file set, all placed in the project root:

[project-name]/
├── .gitignore             # Version control exclusions (.env, secrets, progress files, etc.; template below)
├── CLAUDE.md              # Claude Code's project memory: product context + development guidelines
├── TASKS.md               # Feature breakdown + Phase milestones + per-Task acceptance criteria
├── TICKETS.md             # Ticket content: title, description, acceptance criteria per ticket; PM can create tickets directly
├── docs/
│   ├── PRD.md             # Full PRD (consolidated from the PRD Output Format above)
│   ├── ARCHITECTURE.md    # Technical architecture: directory structure + DB schema + API endpoints + security architecture
│   └── PRODUCT-SPEC.md    # Product Spec Summary
└── scripts/
    └── setup.sh           # One-click initialization script (create directories + install dependencies)

📄 CLAUDE.md Template

CLAUDE.md is Claude Code's project memory file; Claude Code automatically reads it on every startup. It must include:

# [Product Name] — Project Guide

## Product Context

**One-liner**: [PR-FAQ headline]
**Target Users**: [Persona in one sentence]
**Core JTBD**: [Target Customer] wants to [Job] in the context of [Job Context]
**Aha Moment**: When the user completes [action], they experience the core value
**North Star Metric**: [Metric name + definition]

## Tech Stack

- **Frontend**: [Framework + version]
- **Backend**: [Framework + version]
- **Database**: [Type + version]
- **Deployment**: [Platform]
- **Package Manager**: [Tool]

## Development Guidelines

- Develop in [language]
- Follow [style guide / lint rules]
- Commit message format: `[type]: [description]` (type: feat / fix / refactor / docs / test)
- Branch strategy: [main / develop / feature-xxx]
- Every feature must reference its User Story number (see TASKS.md)

## MVP Boundaries

**Must-Have (P0)**:
- [Feature 1]
- [Feature 2]
- [Feature 3]

**Explicitly Not Doing**:
- [Exclusion 1]. Reason: [rationale]
- [Exclusion 2]. Reason: [rationale]

## Key Decision Log

| Decision | Choice | Rationale | Date |
|----------|--------|-----------|------|
| [e.g., Database selection] | [PostgreSQL] | [Needs relational queries + JSON support] | [Date] |

## Risk Alerts (from Pre-mortem)

- ⚠️ [Risk 1]: [Preventive measure]
- ⚠️ [Risk 2]: [Preventive measure]

## Security Notes

> Full security checklist in the Security Checkpoint section below. Below are this product's key security decisions:

- Authentication: [JWT / Session / OAuth]
- CORS policy: [Allowed origins]
- Rate Limiting: [Strategy summary]
- Sensitive data: [Handling approach]

## Development Workflow

Follow the Phase order in `TASKS.md`. After completing each Phase:
1. Verify all Task acceptance criteria pass
2. Ask the user whether to proceed to the next Phase
3. If architectural questions arise, refer to `docs/ARCHITECTURE.md`

Tech Stack (assume and state, do not block)

If the user gave a stack, use it. If not, infer a sensible default from the product type using the recommendation logic below, state your choice in one line, and produce the handoff in the same response. Ask only when the product type itself is genuinely unclear.

Worth stating explicitly (affects all outputs)

1. What type of application is this?
   □ Web App (browser)
   □ Mobile App (iOS / Android / cross-platform)
   □ Desktop App
   □ API / Backend Service
   □ CLI Tool
   □ Other

2. Do you have a preferred tech stack?
   (If not, I'll recommend one based on the product characteristics)

Recommendation Logic (When user hasn't specified)

Application Type	Recommended Stack	Rationale
Web App (fast MVP validation)	Next.js + Tailwind + Supabase	Full-stack in one, easy deployment, built-in Auth
Web App (complex backend logic)	React + Node.js/Express + PostgreSQL	High flexibility, mature ecosystem
Web App (Python team)	React + FastAPI/Django + PostgreSQL	Python ecosystem, Django has built-in Admin
Mobile App (cross-platform)	React Native / Flutter	Single codebase covers both platforms
API Service	FastAPI / Express / Go	Lightweight, high performance

Claude should explain the rationale when recommending and remind the user they can override the recommendation.

Optional (Follow-up based on product needs)

3. Do you need user authentication? (Affects Auth approach selection)
4. Any real-time requirements? (WebSocket / SSE)
5. Need file upload/processing? (Affects storage choice)
6. Where do you plan to deploy? (Vercel / Railway / AWS / self-hosted)

3. TASKS.md, TICKETS.md & Breakdown Logic

📄 TASKS.md Template

Core principles for feature breakdown:

Start from the MVP must-haves (P0 features)
Each Task maps to a User Story
Phases have clear dependencies: Phase N+1 depends on Phase N outputs
Each Task includes acceptance cri

**Provenance:** when you produce a PRD or a development handoff package, contribute the framework tags `PRD`, `Handoff`, and `Security` to the meta-skill's provenance line (`— Frameworks: … · PRD · Handoff · Security · …`).

## Framework

<!-- migrated from references/04b-solutions.md (103-259, PRD template + Mermaid artifacts) + 07a-handoff-core.md (1-152, full) + 07b-tasks-tickets.md (1-215, full) + 07c-architecture-setup.md (1-199, full) + 08-security-checklist.md (1-246). Dropped: the 04b File Integration Tips block (already out of range), the 08 Integration Timing table (referenced old mode names), and the 08 Applicable-style gating. Adapted: 07c's runtime-named "In Claude Chat / Cowork" guidance to lens-neutral wording. Reframed: 08's two always-on-blocking enforcement blocks + FAIL/PASS example ceremony into a proportional security guardrail, per this phase's migration rules. -->

> Read this file, consolidate the outputs from the entire product planning process, and generate a development handoff package that can be used directly in the Claude Code CLI.

#### Environment Constraints & Handoff Strategy

**Key fact: Claude Chat / Cowork and Claude Code are separate runtime environments; you cannot launch Claude Code from within Chat.**

The handoff strategy is therefore: **Produce a structured development handoff package (a set of files)** that the user downloads, places in their project folder, and can kick off the entire development workflow with a single prompt in Claude Code.

The handoff method depends on the user's environment:

| User Environment | Handoff Method |
|-----------------|----------------|
| **Claude Chat (Web/App)** | Produce a zip file for download; user extracts to project directory then opens Claude Code |
| **Claude Cowork (Desktop)** | Same as above, but can write files directly to a user-specified local path |
| **Already in Claude Code** | Create all files directly in the project directory (in this scenario, this skill is likely referenced from CLAUDE.md) |

#### Development Handoff Package Contents

Produce the following file set, all placed in the project root:

```
[project-name]/
