npx skills add a5c-ai/babysitter --skill specification-writing --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
- Formalizing vague feature requests into structured requirements - Clarifying scope boundaries for a feature area - Establishing acceptance criteria for user stories ## Key Principle Specifications describe desired behavior from the user's perspective. They define **what** the system should do, not **how** it should be built. Business value must be explicit in every requirement. ## Process 1. **Elicit requirements** - Extract functional and non-functional requirements from feature description 2. **Write user stories** - Author stories in standard format with personas 3. **Define acceptance criteria** - Testable conditions for each story (Given/When/Then) 4. **Identify edge cases** - Error scenarios and boundary conditions 5. **Clarify gaps** - Surface and resolve ambiguities and contradictions 6. **Document assumptions** - Make implicit assumptions explicit 7. **Define scope** - Clearly delineate in-scope vs. out-of-scope 8. **Human review** - Approve specification before planning ## Tool Use Invoke via babysitter process: `methodologies/spec-kit/spec-kit-specification` Full pipeline: `methodologies/spec-kit/spec-kit-orchestrator`

What does the specification-writing skill do?
Write feature specifications as requirements and user stories with acceptance criteria, focusing on business value and testable conditions.
How do I install it?

Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
