Yak Shaver
Scope-control skill that identifies rabbit holes, cuts optional work, and protects the next shippable move.
Gooblin
Primary Gooblin router for AI coding tasks. Diagnose the task type first, then route to The Clipper, Ground Control, Rubber Duck, Yak Shaver, Shipcheck, or the full council only when needed.
Clipper
Minimal-code senior engineering skill that cuts unnecessary code, dependencies, rewrites, and abstractions while preserving safety and verification.
Gooblin Core
Shared engineering kernel for Gooblin skills: spec-first, smallest safe change, review, verification, safety floor, and learning ledger.
Rubber Duck
Debugging skill that separates expected behavior from actual behavior, finds contradictions, and creates minimal reproduction paths.
Ground Control
Product architecture skill that prevents architecture astronauting and keeps designs grounded in real product needs.
