How does this skill use existing project context?

It scans your repository for 'seed' files, existing specs in the eidos/ directory, and memory files to ensure the questions it asks are relevant and don't repeat information already available.

What is the /eidos:spec command?

The /eidos:spec command is a specialized Claude Code skill that guides you through a structured Q&A session to define the goals, behavior, and design of a feature before any code is written.

What happens after the specification is generated?

Once the spec is created and committed, the skill offers next steps such as creating an implementation plan with /eidos:plan or starting the code changes immediately with /eidos:push.

Why is Spec-Driven Development important for AI coding?

SDD ensures that the AI assistant fully understands the intent and constraints of a task, which significantly reduces errors, prevents technical debt, and leads to higher-quality code implementation.

Where are the generated spec files stored?

Spec files are automatically written to and organized within the eidos/ or eidos/skills/ directories, following standard naming conventions for easy retrieval.

Aprendizaje y Documentación

Facilitates spec-driven development by guiding users through structured Q&A to clarify technical requirements before implementation.

The spec skill implements a robust Spec-Driven Development (SDD) workflow by helping developers move from vague intent to a concrete technical specification. It performs an iterative discovery process—analyzing existing project context, clarifying edge cases, and defining architectural boundaries—before generating a structured spec file. By forcing a 'think-before-you-code' approach, it ensures that implementation is grounded in clear requirements, reducing rework and ensuring alignment across complex technical tasks within the Claude Code environment.
