Workflows move to skills/<name>/SKILL.md so the repo installs as a plugin. scripts/quality-gate runs only the checks of the requested tier on the diff and reports missing tools as unverified instead of passing them. Hooks block stopping on a failed or stale gate, guard destructive shell commands and format edited files with the project's own formatter. Co-Authored-By: Claude Opus 5.5 <[email protected]>
