SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill converts an approved product decision into a literal, agent-ready build specification so implementation and design teams can execute without reinterpreting the strategy.

Core Features & Use Cases

  • Code handoff spec: Produces structured requirements, acceptance criteria, data models, edge cases, constraints, and metrics for Claude Code or Codex.
  • Design handoff spec: Produces screen-by-screen flows, states, copy, and responsive constraints for Figma, wireframing, or Gemini.
  • Decision-safe workflow: Refuses to generate a build brief unless a passing decision-readiness verdict exists, helping teams avoid shipping unvalidated bets.

Quick Start

Ask the skill to turn an approved decision into a build brief for code or design handoff.

FAQPage Schema
How do I turn an approved product decision into a build-ready spec for Claude Code?

A build brief is an agent-ready specification that translates an approved product decision into structured requirements, acceptance criteria, and edge cases so implementation teams can execute without reinterpreting strategy.

What is the best way to generate design handoff specs for Figma from a decision log?

The best way to generate design handoff specs for Figma is to validate an approved decision log and output screen-by-screen flows, states, copy, and responsive constraints for design tools.

Can I generate acceptance criteria and data models without a passing decision-readiness check?

No, you cannot generate acceptance criteria and data models without a passing decision-readiness verdict, because the workflow refuses to create a build brief for unvalidated product bets.

Does the build brief workflow support both code agents and design tools?

Yes, the build brief workflow supports both code agents like Claude Code and Codex, and design tools like Figma or Gemini, producing tailored structured markdown for each handoff type.

How do I extract measurable requirements from a product spec for implementation?

To extract measurable requirements from a product spec, the system validates the approved decision state and generates structured markdown containing constraints, edge cases, and metrics for code agents.
