Conciseness

Nearly every sentence carries a non-obvious operational fact or gotcha — 'patch tags ... live on release/vX.Y and are NOT ancestors of main', 'git cliff fails on such commits (Filter call sort failed)', 'check-release-note-sync requires the post ... to equal the GitHub release body byte for byte' — with no padding and no explanation of concepts Claude already knows. Not 4: no fill-in or over-explanatory passages were found that could be trimmed.

Actionability

Fully executable, copy-paste-ready commands throughout: 'GITHUB_TOKEN=$(gh auth token) git cliff <prev-minor-tag>..$bp --tag vX.Y.0 -o /path/CHANGELOG-vX.Y.0.md', the PR-collection shell loop, the contributor-rebuild comm pipeline, and the worktree + pinned-pnpm build sequence. Not 4: placeholders (e.g. <prev-minor-tag>, <remote>) are resolved by explicit prior steps, and the common cases (minor, patch, pre-release) each have a concrete path.

Workflow Clarity

Clear numbered sequence (sections 1–8) with explicit validation checkpoints and feedback loops: 'Double-check with the user', section 5 'Verify' cross-check against git log, 'Build the site before opening the PR ... If the build fails, fix it or stop', and the flaky-network 're-run until it completes' guidance with a fallback to hand-writing bullets. Not 4: checkpoints and error-recovery loops are explicit at every fragile step rather than only mostly present.

Progressive Disclosure

The entire skill is one ~340-line file with no bundle files at all; distinct sub-workflows such as '## 6. Human-curated sections' (a full editorial style guide) and '## 8. Docs-repo blog variant + draft PR' are inlined rather than split into reference files with pointers. Not 4: content that would naturally live in separate files is inline and there are no references to signal; not 2: the internal structure (numbered sections, clear ### subsections) is well organized and easy to navigate.

Specificity

The description lists multiple specific concrete actions — 'Generate a GreptimeDB release changelog (minor, patch, or alpha/beta/rc pre-release) with git cliff (correct range, subtract already-released patch PRs, rebuild contributors, add human-curated highlights and upgrade notes), output to a file, and prepare the docs-repo blog PR' — covering generation, subtraction, contributor rebuilds, curation, output, and PR preparation. Not 4: coverage is comprehensive rather than having minor gaps; not below because nothing concrete is missing.

Completeness

Explicitly answers what ('Generate a GreptimeDB release changelog ... output to a file, and prepare the docs-repo blog PR') and when ('Use when asked to write/generate a GreptimeDB release note or changelog'). Not 4: the when-clause is explicit with concrete trigger phrases, not merely present.

Trigger Term Quality

Natural trigger phrases like 'release note', 'changelog', 'write/generate', and 'GreptimeDB' appear in an explicit 'Use when asked to write/generate a GreptimeDB release note or changelog' clause. Not 5: a few common variations are absent (e.g. plural 'release notes', 'release announcement', 'publish a release'); not 3: keyword coverage goes well beyond 'some relevant keywords'.

Distinctiveness Conflict Risk

'GreptimeDB release note or changelog' defines a clear product-specific niche with distinct triggers — no other skill would plausibly match these terms. Not 4: there is no overlap risk with closely related skills; the domain naming is unambiguous. Third-person voice is used throughout ('Generate ...'), so no voice penalty applies.
