Request

Skills trial host check before the 2026-10-25 window-end review (docs/decisions/2026-09-25-skills-trial-and-usage.md L1101-1104).

1. At current main, run python3 scripts/skills_status.py --json and record its exit code and result in a value-free receipt. A claude_listing mismatch against adoption/skills/manifest.json needs its own receipt and dated addendum before the review counts this host (the workstation's 2026-09-28 restore is the precedent: PR Skills trial: host listing drift restored to the manifest (14 skills on), receipt and addendum #461).
2. verification-before-completion left the trial on 2026-09-28 (PR Skills trial: remove verification-before-completion under the conflict rule (M4), #381 Amendment 3 #464, c0966da). If it is installed on this host, remove it with the complete host procedure in the M4 addendum of the same decision record (L1384-1397):
   • assert that the canonical ~/.agents/skills/verification-before-completion folder is the only copy (no other agent holds a same-named skill);
   • from an empty working directory, run DISABLE_TELEMETRY=1 skills remove verification-before-completion -g -y through the pinned skills 1.7.0 CLI;
   • read back: no canonical folder, no lock entry, no ~/.claude/skills link.
3. Do not use the agent-scoped form skills remove <name> -g -y -a claude-code codex. That applies to the whole Stage-1 rollback block in evidence/artifacts/mac-stage1-client-layer-20260927/README.md (from L275 on). On skills 1.7.0 the scoped form exits 0 but keeps the canonical folder and its lock entry whenever another detected universal agent resolves to that folder (vercel-labs/skills@7407f389 src/remove.ts L293-340). The workstation reproduced this on 2026-09-28 (evidence/receipts/skills-m4-host-removal-20260928.json). tools/adoption/install_skills.py now reports that case as error (PR install_skills: read back a global rollback like #429's project path; M4 host removal receipt #467, 83229e2).

No response

Acceptance

• A value-free receipt, recorded before 2026-10-25, with the exit code and summary of python3 scripts/skills_status.py --json at a named main commit: result ok, 28 manifest skills, no extra skill, claude_listing equal to the manifest (or a listing receipt and addendum for each difference).
• No copy and no lock entry of verification-before-completion on this host, shown by a read-back (canonical folder, lock file entry, ~/.claude/skills link). If it was never installed here, say so with the same read-back.
• The receipt names the evidence class (native-measurement on this host). The workstation's receipts do not certify this host.
