Individual skill

spec

Create, amend, or backprop bugs into SPEC.md at repo root. Sole mutator of the project spec. Triggers when the user asks to write a spec, start a new spec, distill a spec from existing code, add invariants, amend sections (§G, §C, §I, §V, §T, §B), or record a bug via backprop. Common phrasings: "write the spec for...", "new spec", "bug: ...", "amend §V.3", "distill spec from code", "spec this idea". Reads and follows FORMAT.md for the caveman encoding rules and pipe-table shape of §T and §B.

# spec — spec mutator

Read `FORMAT.md` at repo root if not already loaded. Caveman skill applies to all writes here.

## DISPATCH

Inspect user request and project state:

1. No `SPEC.md` at repo root AND args describe idea → **NEW**
2. No `SPEC.md` AND `from-code` in args → **DISTILL**
3. `SPEC.md` exists AND args start `bug:` → **BACKPROP**
4. `SPEC.md` exists AND args start `amend` → **AMEND**
5. `SPEC.md` exists, no args → ask user which mode
