+summary, decisions, risks, verification results, remaining work, notes, table

   // REGRESSION: unprefixed skills must be real directories, not symlinks (#761)
   // Claude Code auto-prefixes skills nested under a parent dir symlink.
   // e.g., `qa -> gstack/qa` gets discovered as "gstack-qa", not "qa".
