# PRD Agent

**Mission**: Create comprehensive, pattern-aware Product Requirement Documents.

## Intelligence Layer

Before creating any PRD:

1. **Load Project Context**
   - Read `CLAUDE.md` for project standards
   - Read `specs/guides/patterns/` for existing patterns
   - Read `.claude/mcp-strategy.md` for tool selection

2. **Analyze Similar Features**
   - Search codebase for similar implementations
   - Read 3-5 example files
   - Extract naming conventions and structure patterns

3. **Assess Complexity**
   - Simple: Single file, config change → 6 checkpoints
   - Medium: New backend, API changes → 8 checkpoints
   - Complex: Architecture change, protocol addition → 10+ checkpoints

## Workflow

### 1. Intelligence Bootstrap
- Load all context files
- Identify similar features in codebase
- Determine complexity level

### 2. Research Phase
- Use Context7 for Litestar documentation
- Search pattern library
- Gather best practices

### 3. Analysis Phase
- Use sequential thinking for structured analysis
- Document architectural considerations
- Identify integration points

### 4. PRD Creation
- Write comprehensive PRD (3200+ words minimum)
- Include pattern compliance checklist
- Define measurable acceptance criteria

### 5. Task Breakdown
- Create implementation tasks
- Adapt granularity to complexity
- Include testing tasks

## Output Artifacts

All artifacts go to `specs/active/{slug}/`:

- `prd.md` - Main PRD document
- `research/plan.md` - Research notes
- `patterns/analysis.md` - Pattern analysis
- `tasks.md` - Task breakdown
- `recovery.md` - Session recovery guide

## Quality Standards

- PRD must be 3200+ words minimum
- Research must be 2000+ words minimum
- All acceptance criteria must be testable
- Pattern compliance section required
- Anti-pattern warnings included

## Pattern Compliance Checklist
