Conciseness

Most content is necessary and project-specific (exact file tables, command sequences, workflow names), but there is real tightening opportunity: the 10-file version rule is stated twice ("Bump the version string in these 10 files" table, then re-explained including "apps/dsh-plugin/package.json... are among them"), the checklist re-narrates body content with long incident justifications (0.28.32, 0.28.33 anecdotes), and Phase 4's ~40 lines of pipeline internals (Grype database policy, VEX exception policy, SBOM scope) explain what CI does rather than what the agent does. This fits the 3 anchor (mostly efficient but could be tightened); 4 would require only minor instances of over-explanation, and 2 would require padded concept-teaching, which is absent.

Actionability

Guidance is fully executable throughout: exact commands for every phase ("git tag --sort=-v:refname | head -1", "gh pr view <number> --json title,author,body,closedIssues,labels", the build sequence, "gh run watch <run-id> --exit-status", the full attestation-verify and sha256sum blocks), an exact 10-file version table, and copy-paste workflow-dispatch loops. Matches the 5 anchor (copy-paste ready commands covering common cases).

Workflow Clarity

Four phases are clearly sequenced, with explicit validation checkpoints ("Read each file, confirm the current version matches expectations", "Do not tag until all five runs succeeded on the bump commit", "Verify all builds succeed before proceeding"), feedback loops for error recovery ("If one fails, fix it on main and run them again", "If anything is missing, fix it before proceeding to Phase 4", the viewer-pin-live recovery procedure), and before/after-tagging checklists. This is a direct match for the 5 anchor.

Progressive Disclosure

References are one level deep, clearly signaled, and real (all three cited files — release-notes-v0.12.0.md, v0.13.0.md, v0.13.1.md — exist in references/), each annotated with when to use which pattern. However, a meaningful slice of inline content (the Phase 4 pipeline/SBOM/attestation internals and tag-only verification procedure, roughly 80 lines) is self-contained and would fit better in a reference file, so the SKILL.md leans long at ~315 lines. Fits the 4 anchor (good structure, references clear, minor-to-moderate organization gaps); 3 would require references to be unclear or un-signaled, which they are not.

Specificity

The description lists four concrete actions covering the full workflow — "draft release notes with full contributor credit", "bump versions across all package files", "build in dependency order", and "kick off the tag-driven release pipeline" — with comprehensive coverage and no gaps. This matches the 5 anchor (multiple specific concrete actions, comprehensive); 4 would require minor gaps in coverage, which are absent.

Completeness

Both questions are answered explicitly: the "what" is the four concrete actions, and the "when" is given twice — "Use this skill whenever the user mentions..." and "Also trigger when the user says things like 'let's ship'..." — with concrete trigger phrases. This is a direct match for the 5 anchor; 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Formal triggers ("preparing a release", "bumping versions", "writing release notes", "tagging a release", "publishing") are supplemented with natural colloquial variations users would actually say: "let's ship", "prep a release", "what's changed since last release", "time to cut a new version". Coverage of natural terms including synonyms matches the 5 anchor; 4 would mean a few natural terms are missing, but both formal and casual phrasings are present.

Distinctiveness Conflict Risk

The niche is clear (Plannotator's release process, anchored by the project name and "tag-driven release pipeline"), but trigger phrases like "bump versions", "publishing", and "prep a release" are generic release vocabulary that could overlap with release/changelog skills for other projects in a multi-project setup. This fits the 4 anchor (mostly distinct, minor overlap risk); 5 would require minimal conflict risk, but the colloquial triggers are not project-qualified, and 3 would imply overlap with broadly similar skills beyond just closely related release skills.
