Individual skill

check

Read-only drift detector. Diffs SPEC.md against current code and reports violations grouped by severity. Writes nothing — suggests remedies via the spec or build skills but never invokes them. Triggers when the user asks to check drift, audit the spec, verify invariants, or ask whether code still matches the spec. Phrasings: "check drift", "audit the spec", "does the code still match §V", "check invariants", "spec vs code".

# check — drift report

Pure diagnostic. Reports violations. Writes nothing. User decides remedy.

Spec drifting silently from code is the #1 SDD failure mode. check is the
detector. Run it after each `/build` and before each ship — drift caught here is
a diff; drift caught in prod is a §B.

## LOAD

1. Read `SPEC.md`. If missing → "no spec, nothing to check." Stop.
2. Parse invocation args:
   - `§V` → check invariants only (default)
   - `§I` → check interfaces
