What are the standard identifiers used by the skill?

The skill uses a standardized format: BR for Business Rules, US for User Stories, and AC for Acceptance Criteria, each with a 3-letter domain code and sequential numbering.

Will it overwrite my custom documentation edits?

No, the skill includes an idempotency feature that preserves content within specific 'manual' comment tags during regeneration.

Can this skill detect features from existing code?

Yes, the Analyze Mode scans models, routes, and services to infer business rules, operations, and entities directly from your existing codebase.

What documentation format does the skill produce?

It generates a structured directory of Markdown files organized by feature phases, including a README index and Mermaid-based dependency graphs.

Collaboration Tools

Generates structured feature specifications including business rules, user stories, and acceptance criteria through codebase analysis or interactive design.

The Feature Specification skill transforms how teams document requirements by automating the creation of detailed technical documentation directly from code or project concepts. It organizes features into logical phases—from core entities to complex workflows—and enforces standardized naming conventions for Business Rules (BR), User Stories (US), and Acceptance Criteria (AC). Whether you are auditing an existing Python backend to understand its logic or planning a new system from scratch, this tool ensures consistent, cross-referenced, and maintainable documentation that stays in sync with your development progress using idempotency and manual edit preservation.
