Green-Field Development
Run the green-field development workflow to build new systems from scratch using Spec-Driven Development (SDD).
When to Use This Skill
- User requests building a NEW system with no existing codebase
- User says "create a new app/service/project"
- User provides high-level requirements for a green-field build
- User wants to scaffold a complete application from requirements
What This Skill Does
This skill delegates to the authoritative green-field workflow at .github/prompts/green-field.prompt.md, which orchestrates:
- Intake & Clarification — Gather requirements, choose execution approach (Custom Agents or Squad), select optional SDD framework
- Analysis — Decompose into functional domains
- Capability Mapping — Identify required skills, MCP servers, instructions
- Capability Acquisition — Discover or build missing capabilities
- Team Formation — Assign capabilities to agent roles, define handoff DAG
- Execution — Execute iteratively with reviewer gates
- Verification — Validate deliverables and calculate confidence score
- Handoff — Generate progress report and package artifacts
Read and execute .github/prompts/green-field.prompt.md in full — it is the single source of truth for the green-field workflow.
VS Code Users
VS Code users can invoke this workflow directly via the /green-field slash command instead of using this skill. Both surfaces share the same authoritative prompt file.
