SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you turn an already investigated product problem or bet into a clear decision artifact for humans, so teams can align, choose, or pressure-test a plan without turning it into a PRD or implementation spec.

Core Features & Use Cases

  • Narrative report: Writes a persuasive, human-facing opportunity brief that explains the problem, why now, impact, and the ask.
  • FAQ completeness gate: Produces a hard-questions appendix that answers the most important questions about the problem, alternatives, limitations, risks, and success measures.
  • Decision memo: Creates an options-based memo that compares choices, including do-nothing, recommends one path, and states a concrete ask.
  • Use case: A product leader uses it after discovery work is complete to summarize the evidence and force a decision on whether to proceed.

Quick Start

Ask the skill to write a brief for the decided problem using the narrative, FAQ, or memo style you want.

FAQPage Schema
How do I write an opportunity brief from product discovery evidence?▼

To write an opportunity brief, you synthesize investigated product evidence into a persuasive, human-facing narrative that explains the problem, why now, impact, and the ask. This format helps product leaders align teams without creating a full PRD.

Can I generate a hard-questions FAQ to pressure-test a product bet?▼

You can generate a hard-questions FAQ to pressure-test a product bet by producing an appendix that answers important questions about alternatives, limitations, risks, and success measures. This gates decision-readiness using evidence-backed structure.

How do I turn product evidence into a traceable decision document?▼

You turn product evidence into a traceable decision document by applying evidence-backed structure and decision-readiness gating. The output supports concise, traceable claims without inventing metrics, ensuring teams align on investigated facts.

Do I need completed discovery work before writing a product brief?▼

You need completed discovery work before writing a product brief. This Skill synthesizes already investigated product problems and decision context into decision artifacts, so prior evidence gathering is a prerequisite for concise, traceable claims.
