Conciseness

Every line carries repo-specific knowledge Claude could not infer — 'the ungated `draft-notes` job', 'gated job publishes it exactly as edited', 'Give the PR the `chore` label' — with no padding or explanation of concepts Claude already knows. The 'How notes work now (#685)' section is exactly the non-obvious context the skill exists to convey.

Actionability

The checklist is copy-paste executable: 'Bump version in `pyproject.toml`', 'Update lockfile: `uv lock`', 'Sanity checks (optional unless requested): `just test-fast`, `just build`', plus a concrete commit format 'release: prepare <version>' and an example release note. No pseudocode or vague direction anywhere.

Workflow Clarity

The checklist gives a clear ordered sequence with explicit validation commands (`just test-fast`, `just build`) and a guardrail ('Do not tag releases locally unless explicitly requested'). The notes section includes a recovery loop ('A re-dispatch never overwrites an existing draft; delete the draft to re-harvest'). This is a simple single-purpose skill and the task is unambiguous; the operation is neither destructive nor batch, so the validation cap does not apply.

Progressive Disclosure

The body is under 50 lines with two well-organized sections ('How notes work now (#685)', 'Release-prep PR checklist') and no need for external reference files. Per the rubric's simple-skill guideline, this earns full credit with well-organized sections alone.

Specificity

Names fully concrete actions — 'version bump + uv lock' — and concretely scopes the notes workflow ('harvested from PR release-note blocks and live in GitHub Releases'). It sits between anchor 3 (1-2 actions, not comprehensive) and anchor 5 (comprehensive action list) because only two explicit actions are named and prep-PR conventions (label, commit format) are omitted — noticeably above the midpoint but with minor coverage gaps.

Completeness

Explicitly answers both questions: what ('Prepare a release in mflux (version bump + uv lock; ...)') and when ('Use when preparing a release branch or release PR'). The when-clause is explicit but narrow — it largely restates the what rather than adding distinct trigger variations — so it fits anchor 4 ('when' could be more explicit or specific) rather than anchor 5's concrete, varied trigger phrases.

Trigger Term Quality

Includes natural phrases a user would say: 'prepare a release', 'release branch', 'release PR', 'version bump'. A few common variations are missing (e.g., 'cut a release', 'bump the version', 'release notes'), matching anchor 4's 'good keyword coverage; a few natural terms missing' rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

'Prepare a release in mflux' plus the 'release branch or release PR' trigger carves out a clear niche with distinct triggers; no plausible conflict with other skills. Matches anchor 5 exactly, and the repo-scoped naming makes accidental triggering for another skill essentially impossible.
