spec-creation
Feature specification creation from codebase research. Produces requirements, acceptance criteria, architecture decisions, implementation plans, and risk analysis.
npx skills add a5c-ai/babysitter --skill spec-creation --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.
- Identify existing patterns and conventions - Map dependencies and integration points - Review existing tests for testing patterns - Document technical constraints ## Specification Components ### Scope and Non-Goals Clear boundaries on what the feature does and does not include. ### Functional Requirements Detailed requirements with unique identifiers for tracking. ### Acceptance Criteria Testable, measurable criteria for each requirement. ### Architecture Decisions Decision records with rationale and alternatives considered. ### Implementation Plan Phased approach ordered by dependency, not priority. ### Risk Analysis Identified risks with probability, impact, and mitigation strategies. ### API Contracts and Data Models Interface definitions and data model schemas. ### Test Strategy Mapping of unit, integration, and E2E tests to requirements. ## Output Specifications are saved to `docs/specs/{feature}.md` for reference by the execution workflow. ## When to Use - `/spec:create [feature]` slash command - Before starting a new feature implementation - When planning complex multi-module changes ## Processes Used By - `claudekit-spec-workflow` (create mode)

What does the spec-creation skill do?
Feature specification creation from codebase research. Produces requirements, acceptance criteria, architecture decisions, implementation plans, and risk analysis.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill spec-creation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
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.
