Agent Skills: blueprint

Turn a working session — the docs, issues, and half-formed ideas you've fed in, plus anything you point it at — into a spec and then a set of self-contained, executable implementation plans for OTHER models/agents to build. A senior architect that plans but never implements. Use when you have that context in hand and want it distilled into a PRD-style spec and broken into dependency-ordered, verifiable work items. Publishes to the repo's configured issue tracker or to markdown files.
