SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Teams struggle to translate vague ideas into actionable, decision-ready specs. This skill applies the Linear Method and 4D Context Canvas to deliver concise, context-rich specs that align teams quickly.

Core Features & Use Cases

  • Level 1 Quick Task generation for fast tasking
  • Level 2 Lite PRD for cross-functional alignment
  • Level 3 AI Feature specs with explicit context requirements and evals
  • Supports context engineering practices and pragmatic scoping down to 1-3 weeks
  • Reference-driven guidance with a living annex of examples and patterns

Quick Start

Describe a project brief and I will generate a Level 1 Quick Task ready for Linear.

FAQPage Schema
How do I write a product spec from a vague idea?

To write a product spec from a vague idea, apply the Linear Method and 4D Context Canvas to translate broad concepts into decision-ready specs. This approach prioritizes prototypes over documentation and pragmatic scoping down to 1-3 weeks.

What is the best way to create an AI feature spec with context requirements?

Creating an AI feature spec requires explicit context requirements and clear evaluation criteria. Using a Level 3 spec template enforces context engineering practices, ensuring your AI feature specs include built-in evals and decision paths.

How do I scope down product documentation for cross-functional alignment?

Scope down product documentation by generating a Level 2 Lite PRD that enforces Linear Method guidelines. This delivers concise, context-rich specs designed to align cross-functional teams quickly without excessive documentation.

Can I generate quick tasks for Linear directly from a project brief?

Yes, you can generate quick tasks for Linear directly from a project brief. By creating a Level 1 Quick Task spec, you translate a brief description into fast, actionable tasking ready for immediate execution.

Does context engineering work for short 1-3 week product cycles?

Context engineering works for short 1-3 week product cycles by enforcing pragmatic scoping down and prioritizing prototypes over documentation. This ensures specs remain concise, actionable, and decision-ready within tight timelines.

When should I use a Lite PRD instead of a full AI feature spec?

Use a Lite PRD for cross-functional alignment on standard tasks, whereas an AI feature spec is needed when your project involves explicit context requirements and evaluation criteria. The choice depends on the technical depth and AI integration required.
