Implan

Implan is an opt-in structured planning workflow. Trigger ONLY when the user explicitly invokes it ("/implan", "create an implan", "make an implan", "start an implan", "use Implan for X", "set up an Implan for Y") or is actively working inside an existing `ai-plans/` directory. Do NOT trigger for general planning conversations, even substantial ones, and do NOT trigger just because the user says things like "plan a feature", "plan a project", "plan a launch", "plan a campaign", or "set up a plan"; those phrases alone are not enough. Most planning discussions do not need Implan, and unwanted activation creates files, folders, and friction. When invoked, Implan produces a self-contained Plan Directory under `ai-plans/` containing a main plan, a mental model with diagrams, a test strategy (the Definition of Done the work iterates towards), and a notes scratchpad, designed so a fresh agent or the user themselves can pick the work up cold and execute it well. Suits anything substantial, code or otherwise (software features, product launches, campaigns, research projects, workshops, anything non-trivial). This skill is for PLANNING ONLY; execution happens in a separate session afterwards. Do NOT trigger for Claude Code's built-in Plan Mode or other planning methodologies.
