Conciseness

Extremely dense with repo-specific rules and no explanations of concepts Claude already knows, but at ~300 lines there are trimmable spots: the three-readers framing paragraph, and the tracker-fix "present effect only" rule repeated across Impact, Summary, and the Step 6 checklist — efficient with minor over-elaboration, matching anchor 4 rather than anchor 5's every-token-earns-its-place.

Actionability

Fully executable throughout: the exact skeleton block, worked title examples, per-section templates (owner-action lead-ins, the four-field decision format, the test-plan table), and copy-paste commands including the gh REST open call with flags explained, the full GraphQL closing-issues query, and grep/awk verification pipelines — matching the copy-paste-ready anchor.

Workflow Clarity

A clear six-step sequence with explicit validation and feedback loops: the pre-send checklist of grep commands, the closes-registration loop ("If one is missing... fix the file, PATCH it, check again"), and the merged/closed state check that halts before any edit — matching the anchor requiring explicit validation, error-recovery loops, and checklists.

Progressive Disclosure

The single bundle file, references/examples.md, exists, is referenced early and clearly signaled ("A worked body, before and after, is in references/examples.md"), and is exactly one level deep with no buried or nested references; the body is cleanly sectioned and the bulky worked example is appropriately offloaded — matching the clear-overview anchor.

Specificity

Enumerates multiple concrete deliverables — "the title, the six sections", "the Closes and Part of lines", "owner and deploy actions, an honest test plan, the faults agent-written bodies fall into, and the command that opens or edits it" — comprehensively covering what the skill body actually teaches, matching the comprehensive-coverage anchor rather than anchor 4's minor-gaps profile.

Completeness

Opens with an explicit "Use when" clause carrying three concrete triggers ("at prep-pr Step 8, when a later commit or a review makes the body untrue, or for any pull request that closes public issues or private tracker findings") and follows with an explicit what via "Covers the title, the six sections and what each holds" — both halves answered explicitly with trigger phrases.

Trigger Term Quality

Good natural-keyword coverage ("writing or editing a pull-request title and body", "closes public issues", "test plan", "deploy actions"), but the abbreviation "PR" — the term a user is most likely to say — never appears, and no synonyms beyond "pull-request" are given, so it falls short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

A clear niche (PR title and body prose in this repository) with distinct triggers including the "prep-pr Step 8" handoff and "private tracker findings", which explicitly draws the boundary against the one closely related skill — minimal conflict risk.
