  • heavy-planner

    Creates high-clarity product and technical specifications by interrogating requirements before planning. Use when the user asks to "crear especificaciones", "write a spec", "define requirements", "hacer el plan", "scope a project", or shares an idea that is still vague. This skill asks exhaustive follow-up questions first and only proposes a structured plan after unknowns are surfaced.

  • workflow-orchestration

    Orchestrates structured task execution with planning, progress tracking, self-improvement, and verification gates. Use at the start of any coding session, when given a non-trivial task (3+ steps or architectural decisions), when corrected by the user, when fixing bugs, or when the user mentions "plan", "todo", "track progress", "verify", "lessons learned", "fix this bug", or "task management".

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
