Conciseness

Every line is instructive — 'Never merge it', 'Disable existing auto-merge and remove the PR from any merge queue before work begins', 'call `unwatch_pull_request` before the handoff' — with zero padding and no explanation of concepts Claude already knows. The 47-line body assumes competence throughout.

Actionability

Concrete, executable deltas are given (allowed git operations including `--force-with-lease`, 'Fetch the target branch and check the live PR's head, base, checks, reviews, and mergeability', the `unwatch_pull_request` call), but the core workflow is delegated entirely to '../full-send/SKILL.md', which is not part of this bundle, so the guidance is not self-contained. Not score 5 because executing the proof/review/babysitting steps requires an external file; not score 3 because the override rules and handoff criteria present here are specific and directly executable.

Workflow Clarity

The delta workflow is clearly sequenced with explicit checkpoints: 'check again before each push', 'recheck behavior changes and meaningful conflict fixes before handoff', 'Confirm it is open, not a draft', plus a three-outcome decision checklist (Ready / Waiting / Blocked). Not score 5 because the underlying sequence (proof rules, review, merge gate) is inherited from full-send rather than restated, leaving the full end-to-end order implicit across two files.

Progressive Disclosure

Under 50 lines with no bundle files of its own, well-organized into 'No merging' and 'Stop at the gate' sections, and a single clearly-signaled one-level-deep reference ('Read [full-send](../full-send/SKILL.md)'). The simple-skill exception applies; the only caveat is that the referenced sibling skill is not verifiable within this bundle.

Specificity

The description contains no action verbs or capability statements at all — the only concrete content is 'Trigger this if the user says 'full stop''. It names no domain and no actions, matching the 'no concrete actions' anchor; it cannot score 2 because even 'minimal or generic' actions are absent.

Completeness

Only the 'when' half is present (explicit trigger guidance on 'full stop'); the 'what' — preparing a PR to merge-ready state without merging — is entirely missing from the description. This matches the anchor 'only 'when' is present without 'what''; it cannot score 3 because there is no 'what' at all, only a weak implication from the skill name.

Trigger Term Quality

'full stop' is exactly the natural phrase a user would say, and the description even captures the disguised variant 'even as a closing "Full stop." that reads like emphasis'. Not score 5 because coverage is limited to that single phrase family — no synonyms or alternate phrasings are included; not score 3 because the covered trigger is precise and includes a non-obvious usage pattern.

Distinctiveness Conflict Risk

'full stop' is a distinctive trigger phrase with clear separation from the closely related 'full send' skill, and the deliberate capture of the emphatic closing usage is an explicit design choice rather than accidental overlap. Conflict risk with other skills is minimal.
