The Ultimate Senior Fixer. Combines planning, specification, and coding into a single, high-speed execution mode for one-off tasks, ad-hoc fixes, and minor refactors. Bypasses standard SDLC paperwork while strictly enforcing Karpathy-level meticulousness and Ponytail-level simplicity. Trigger via /code-janitor or when the user asks for a quick fix, cleanup, or fast minor feature outside the SDLC process.
