Revisa los cambios (el diff) como un ingeniero senior contra la spec, mirando alcance, correctitud, simplicidad y consistencia. Úsala antes de commitear o mergear, cuando se pida revisar el código o el diff.
Reviews the changes (the diff) as a senior engineer against the spec, looking at scope, correctness, simplicity and consistency. Use it before committing or merging, when a review of the code or the diff is requested.
Implements ONE single task from an existing spec, without touching anything else. Use it when a spec file exists in the specs folder and the user asks to run or implement a concrete task (for example T1 or T2).
Verifies that a task is actually done by running its Verify step and showing the real output, no self-reporting. Use it after implementing a task, when you want to confirm it truly works and not just that the agent claims so.
Turns a vague idea or feature into an executable spec using the 5 questions (context, goal, constraints, tasks and verification) before writing any code. Use it when the user describes something they want to build and asks for a spec, or to plan the work before implementing.
Writes the commit message for the staged changes, in conventional commits format and explaining the why. Use it when you want to commit or generate the commit message.
Draws, in ASCII, the sequence diagram and the flow diagram of a piece of existing code, to understand how it works before modifying it. Use it when the user wants to understand an existing flow, function or feature, or before scoping over legacy code.
Implementa UNA sola tarea de una spec existente, sin tocar nada más. Úsala cuando exista un archivo de spec en la carpeta specs y el usuario pida ejecutar o implementar una tarea concreta (por ejemplo la T1 o la T2).
