Gepetto

This is a heavyweight planning workflow that breaks down feature implementation through structured phases: research, stakeholder interviews, spec synthesis, and multi-LLM review (it pulls in Gemini and another model for feedback). The output is a detailed implementation plan that gets split into self-contained section files, each with dependencies, acceptance criteria, and file lists. It's built for scenarios where you need serious upfront analysis rather than diving straight into code. The workflow writes everything to markdown files in a planning directory and can resume from any step if interrupted. Overkill for small features, but legitimately useful when you're tackling something complex enough that you'd benefit from forcing yourself to think it through systematically before touching the codebase.
