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.

Review
juliusbrussee
Adversarially reviews a written spec before implementation, citing evidence and ending in a go/no-go gate.
Research
juliusbrussee
Gather external knowledge the spec needs and distill it into §R — the durable research log — so build grounds in facts instead of hallucinating library behavior. Each finding cites a source; unsourced claims are flagged, never written as fact. Triggers when a spec decision hinges on a library/API/best practice the agent is unsure of, when the user says "research this", "what's the best lib for…", "check current best practice", or invokes /ck:research. Defers the §R write to the spec skill.
Grill
juliusbrussee
Interrogates a vague idea one question at a time, recommending answers and parking unknowns before a spec is written.
Deepen
juliusbrussee
Proposes refactors that make shallow code modules deeper, shrinking interfaces while keeping behavior and tests unchanged.
Check
juliusbrussee
Read-only drift detector that diffs SPEC.md against code and reports violations by severity.
Caveman
juliusbrussee
Compresses SPEC.md and spec-adjacent writing into a terse symbol-based notation that cuts tokens while preserving facts.
