rainman

Audit whether an older repository is "built right for today's Claude," and migrate it — subtractively and safely. Use when a project predates today's conventions (a lean CLAUDE.md, skills, hooks, a web SessionStart setup, MCP) and you want to know what's ready, what's bloated, and what's missing. It first produces a non-mutating READINESS REPORT across every pillar — rules (CLAUDE.md), the verify loop (tests + lint), web/session setup, workflow automation, and recallable history/memory — then a migration plan for one approval. Diagnosis is comprehensive; prescription stays subtractive: it shrinks always-on context (relocating rules/history/automation out of CLAUDE.md into skills/hooks/memory) and recommends ADDING only what the project demonstrably needs — never a bloat checklist. Nothing mutates without approval. Optional rainman lane backfills lost context from git history.
