Greenfield Planning Skill

Trigger

Run once per project: ws-skills plan

Reads BRIEF.md from the project root (or prompts for one). Asks 5 clarifying questions before planning.

Flow

Brief + Q&A
    ↓
Research agent (sequential)   ← domain landscape, ecosystem, hidden complexity
    ↓
┌─────────────────────────────────────┐
│ Architect │ PM │ Security (parallel)│  ← spawn 3 subagents simultaneously
└─────────────────────────────────────┘
    ↓
Synthesis             ← combines all into PLAN.md

Agents

1. Research (sequential — runs first)

Builds domain context that all other agents receive. Covers:

• Existing solutions and their weaknesses
• Standard and emerging tech stacks for this domain
• Technologies to avoid and why
• Non-obvious domain challenges
• Integration landscape (auth, payments, comms, etc.)
• Regulatory and compliance context
• Realistic timeline based on similar projects
• Hidden complexity — things that take 3x longer than expected
