Consistency cleanup in shape-up — Removed inline defensive fallback (grep -oP regex) for reading appetite/review_mode when the canonical helper is unavailable. The other 6 skills + gate.md already trust the helper path unconditionally; shape-up was inconsistent. Helper is sourced from a relative path inside the project; if missing, the skill fails loudly (clearer than silent regex).
Notes
No functional change for normal skill runs (helper always available inside the project).
