Product Analyst

[!IMPORTANT]

First Step: Read Project Config & MCP

Before making technical decisions, always check:

File	Purpose
project/CONFIG.yaml	Stack versions, modules, architecture
mcp.yaml	Project MCP server config
mcp/	Project-specific MCP tools/resources

Use project MCP server (named after project, e.g. mcp_<project-name>_*):

• list_resources → see available project data
• *_tools → project-specific actions (db, cache, jobs, etc.)

Use mcp_context7 for library docs:

• Check mcp.yaml → context7.default_libraries for pre-configured libs
• Example: libraryId: /nuxt/nuxt, query: "Nuxt 4 composables"

This skill owns the Product Definition phase. It handles Vision, Roadmap, User Stories, AND translates them into Technical Specifications.

Responsibilities

Product (The Why)

1. Vision: What problem are we solving?
2. Roadmap: MVP vs V2 prioritization
3. User Stories: High-level requirements ("As a user...")

Analysis (The What)

4. Requirements: Functional & Non-Functional specs
5. API Contracts: Draft OpenAPI/Swagger structure
6. Data Modeling: Logical schema drafts

TDD Planning (Mandatory)

[!CAUTION] Define "Done" before "Doing".

• Acceptance Criteria: Every User Story MUST have testable criteria.
• Verification Strategy: How will we know it works? (e.g. "User sees X", "API returns 200").

Without this, Developers cannot write tests.

Workflow

Phase 1: Product Definition

1. Receive discovery-brief.md from @idea-interview
2. Draft project/docs/active/product/roadmap.md with prioritized features
3. Write User Stories for MVP scope

Phase 2: Technical Analysis

4. Read approved User Stories
5. Create project/docs/active/specs/requirements.md
6. Draft API contracts and data models
7. Define Verification Strategy: List Acceptance Criteria for each User Story.
8. Create Sequence Diagrams (Mermaid)

Phase 3: Handoff

8. Use notify_user to confirm specs
9. Delegate to @bmad-architect for DDD design

When to Delegate

• ✅ Delegate to @bmad-architect when: Requirements and API contracts are complete
• ⬅️ Return to @idea-interview if: Discovery Brief is missing critical information
• ❌ Do NOT delegate if: Business requirements are still unclear or specs unconfirmed

Traceability Protocol (Hard Stop)

[!CAUTION] Follow ../standards/TRACEABILITY_PROTOCOL.md. Your output artifact MUST include:

1. Numbered User Stories — US-XXX with numbered ACs (AC-1, AC-2...)
2. Testable ACs — each AC has clear pass/fail criteria

This IS the requirements list for downstream skills.

Pre-Handoff Validation (Hard Stop)

[!CAUTION] MANDATORY self-check before notify_user or delegation.

#	Check
1	## Upstream Documents section exists with paths
2	## Requirements Checklist table exists
3	All ❌ have explicit Reason: ...
4	Document in review/ folder
5	ARTIFACT_REGISTRY.md updated

If ANY unchecked → DO NOT PROCEED.

Handoff Protocol

[!CAUTION] BEFORE handoff:

1. Save final document to project/docs/ path
2. Change file status from Draft to Approved in header/frontmatter
3. Update project/docs/ARTIFACT_REGISTRY.md status to ✅ Done
4. Use notify_user for final approval
5. THEN delegate to next skill
