How does it differ from a standard PR description?

Unlike simple descriptions, ls-epic focuses on traceability, nesting Test Conditions directly under Acceptance Criteria and defining strict data contracts before coding begins.

What is the ls-epic skill?

It is a specialized capability for Claude Code that implements the Liminal Spec methodology to create highly detailed, functional epics for software development.

Should I include technical implementation details in an Epic?

Generally no. This skill encourages a functional-first approach where technical implementation is reserved for the Tech Design phase to ensure requirements remain clear and implementation-agnostic.

Does this skill help with testing?

Yes, it automatically links Acceptance Criteria to specific Test Conditions (TCs), providing a clear blueprint for both manual QA and automated test suites.

Productividad y Flujo de Trabajo

Generates comprehensive, traceable functional epics and requirements using the Liminal Spec development methodology.

The ls-epic skill transforms raw requirements into the primary artifact of the Liminal Spec methodology: a complete, traceable Epic. It enables Claude to act as a digital Product Owner or Tech Lead, structuring documentation around User Profiles, functional flows, and co-located Acceptance Criteria and Test Conditions. By enforcing a functional-first approach that separates 'what' the system does from 'how' it is built, this skill ensures that requirements are unambiguous, testable, and ready for technical design or AI-assisted implementation.
