A skill that plans, writes, validates, proves, reviews, migrates and publishes Claude Code mods. Plan first with the smallest $ surface, a footprint diffed against the plan, a test seen failing, an isolated load that leaves evidence files, a five-line threat model, and a handoff that names what was and was not proven. Brainstorm mode checks ideas against every mod already on GitHub.
