Conciseness

The body is dense and imperative with zero concept explanations ("Permission to push is not permission to merge", "Never enable auto-merge"), assuming Claude's competence. Minor trimmable material keeps it below lean-perfect: the opening paragraph restates the description's scope, and the Codex goal/heartbeat paragraph carries environment-specific detail that not every runtime needs.

Actionability

Mostly executable with copy-paste-ready commands: `gh pr merge <number> --squash --admin --match-head-commit <head-oid>`, `corepack pnpm ship:push -m "<subject>"`, `gh api user --jq .login`, `pnpm worktrees:prune --apply`. Minor gaps: PR creation is described ("Open one ready (not draft) PR") without an explicit command, and the validation step defers to `pnpm guards` selection rather than naming commands.

Workflow Clarity

A clear numbered sequence (Preflight → Validate/push → Open PR → Babysit → Merge gate → After merge) with explicit validation checkpoints: a merge-gate checklist held for 10 minutes on an unchanged head, OID verification recorded before merging, `--match-head-commit` protection, and feedback loops for CI failures and review threads (fix → reply → one batched push → re-check). The semi-irreversible merge operation has extensive validation, so no cap applies.

Progressive Disclosure

No bundle files exist; the single-file body (~130 lines) is well organized into numbered sections with clearly signaled references to sibling skills (/babysit-pr, /new-branch, /review-latest-feedback step 5). It exceeds the under-50-line simple-skill exception, and content like the worktree-rotation and throwaway-worktree pruning rules could arguably live in a reference file, placing it at good-structure-with-minor-gaps rather than fully appropriate splitting.

Specificity

The description lists multiple concrete actions covering the full pipeline — "Commit and push", "open a ready PR", "babysit it through CI and review", "admin-merge", "rotate the worktree" — matching the comprehensive-coverage anchor. It stays in third-person imperative voice with no vague padding, so it does not fall to the minor-gaps anchor at 4.

Completeness

It explicitly answers both "what" (commit, push, open PR, babysit CI/review, admin-merge, rotate worktree) and "when" ("Use when the user asks to ship, publish, or hand off local changes") with concrete trigger phrases, plus deployment consequences. The explicit trigger-based when-clause places it clearly at the top anchor, not 4.

Trigger Term Quality

"Use when the user asks to ship, publish, or hand off local changes" provides natural trigger terms users would actually say. It misses common synonyms such as "open a PR", "merge", or "land it", which keeps it at good-but-not-comprehensive coverage rather than the 5 anchor.

Distinctiveness Conflict Risk

The niche (full ship-through-merge pipeline) is distinct with clear triggers, but closely related skills exist in the same ecosystem (/ship-and-monitor, /babysit-pr) and the description does not draw that boundary itself. Minor overlap risk with closely related skills matches the 4 anchor rather than minimal-conflict 5.
