Conciseness

The body is a dense, repo-specific runbook that assumes Claude's competence — it explains no general concepts (no semver or git tutorials) and nearly every line encodes a non-obvious project rule. It falls short of anchor 5 because the CI Trigger Chain section uses long run-on paragraphs and the 'gh release list' jq command is repeated verbatim in Steps 1 and 6, both of which could be tightened.

Actionability

Fully executable throughout: copy-paste-ready bash blocks with placeholders ('git checkout -b release/v{version}', 'git commit -S --signoff -m "chore(release): prepare v{version}"'), exact semver regexes, exact script invocations ('node scripts/release/sync-release-history.js --target-version {version}'), and a concrete bilingual release-note template. Specific commands cover the common cases.

Workflow Clarity

A clearly sequenced six-step workflow with explicit validation checkpoints and feedback loops: pre-flight checkout validation ('Stop before editing files if any check fails'), a validator script in Step 4 ('stop if it rejects'), user confirmation in Step 5, and a full revalidation suite in Step 6 (baseline re-match, allowed-paths check, signature/DCO verification). This matches the anchor with explicit validation steps and error-recovery guidance.

Progressive Disclosure

Good section structure (Arguments, Workflow with six steps, CI Trigger Chain, Constraints) with all guidance at one level and no nested or dead references — verified there are no references/, scripts/, or assets/ bundle files. It stops short of anchor 5 because a few borderline-externalizable sections (the CI Trigger Chain and backport-workflow narrative) are inlined in a ~217-line file where a separate reference file could keep SKILL.md as a tighter overview.

Specificity

Lists four concrete, specific actions — 'collecting commits, generating bilingual release notes, updating version files, and creating a release branch' — covering the full release-preparation workflow comprehensively. This matches the anchor for multiple specific concrete actions with comprehensive coverage, not the score-4 anchor with coverage gaps.

Completeness

Explicitly answers what ('Prepare a new release by collecting commits, generating bilingual release notes, updating version files, and creating a release branch') and when ('Use when asked to prepare/create a release, bump version, or run /prepare-release') with concrete trigger phrases, matching the anchor 5 example structure exactly.

Trigger Term Quality

Natural phrases like 'prepare/create a release', 'bump version', and the '/prepare-release' slash command are present, but common synonyms users might say ('new version', 'release notes', 'cut/publish a release') are missing. Good keyword coverage with a few natural terms missing fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The bilingual-notes and release-branch actions plus the '/prepare-release' command make the skill mostly distinct, but 'bump version' and 'prepare a release' are generic phrases that overlap generic versioning/release skills, and no product name anchors the niche. Minor overlap risk with closely related skills fits anchor 4 rather than the clear-niche minimal-conflict profile of anchor 5.
