Conciseness

The body is efficient and assumes Claude's competence — it never explains git or branching basics — but "Prerequisites" and "Graceful Degradation" overlap, and the "Output" section repeats stale information. These are minor instances of over-explanation that could be trimmed, matching anchor 4 rather than the fully lean anchor 5.

Actionability

Fully executable, copy-paste-ready guidance: the exact availability check (`git rev-parse --is-inside-work-tree`), concrete Bash and PowerShell invocations with a worked example value, an explicit `GIT_BRANCH_NAME` contract, and an exact validation regex. Specific examples cover the common cases, matching anchor 5.

Workflow Clarity

Clear sequence (verify git → resolve inputs → compose name → execute → validate) with an explicit post-creation validation regex and abort-on-mismatch. Not 5 because recovery stops at 'abort and report' with no fix-and-retry guidance, and the final Output section's examples (`003-user-auth`, `20260319-143022-user-auth`) contradict the mandated naming scheme, creating sequence ambiguity.

Progressive Disclosure

Well-organized single-file structure with clear section headers and no nested or buried references; no bundle files exist and none are needed for this single-task skill. Not 5 because at ~105 lines it exceeds the under-50-line simple-skill zone and the contradictory trailing Output section is a minor organization gap, matching anchor 4.

Specificity

"Create a feature branch with sequential or timestamp numbering" names the git-branching domain and one concrete action plus a specific numbering mechanism, matching 'names domain and 1-2 concrete actions, but not comprehensive'. It is more concrete than the generic anchor 2 ('Processes PDF files') but lacks the several-action coverage of anchor 4.

Completeness

The "what" is clear (create a feature branch with a given numbering scheme) but there is no "Use when..." clause or any equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not 2 because the "what" is concrete, not vague.

Trigger Term Quality

Relevant terms like "feature branch" and "numbering" are present, but common variations a user would naturally say — "git", "new branch", "branch naming", "checkout" — are absent, matching 'some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

"feature branch" combined with the numbering qualifier carves a mostly distinct niche with only minor overlap risk against generic git-branch-creation skills. Not 5 because "create a feature branch" alone could still plausibly trigger for ordinary branch-creation requests.
