The guidance for the feedback memory (when Claude corrects a repeatable step) was tightened:
- Previously: "Edit existing skill files rather than creating new ones (a new project skill shadows a same-named built-in skill), with one exception: if the correction is about how to verify changes in this repo and
.claude/skills/verify/SKILL.mddoes not exist, create it." - Now: "Edit existing skill files only; never create one — a new project skill silently shadows a same-named built-in skill. The single exception is verify..."
The verify exception also gained guidance about scoping: the correction goes in the closest-scoped verify/SKILL.md (repo root vs. subproject), never duplicated.
Evidence
Updated feedback memory string (search for "Edit existing skill files only; never create one", "Each correction lives in exactly one skill file")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
