Conciseness

The body is lean and assumes Claude's competence — no explanations of git or CI basics, and every section conveys repo-specific rules Claude could not infer. Minor trimmable redundancy keeps it below 5: the CHANGELOG-must-be-a-separate-final-commit rule is stated in the checklist, the CHANGELOG conventions, and the Git commits section, and "ASCII only, no em dashes" appears twice. Not 3 because there is no padding or over-explanation.

Actionability

Guidance is concrete and executable for an instruction-only skill: exact file paths (include/SQLiteCpp/<Class>.h, src/<Class>.cpp, tests/<Class>_test.cpp), a command (gh pr create against master), entry formats (- <description> (#NNN), Version X.Y.Z - <year> ???), and step-by-step commit ordering. Minor gaps — no worked example of a good commit message or CHANGELOG line — hold it at 4 rather than 5; it is well above 3 because the guidance is specific rather than pseudocode-level.

Workflow Clarity

The 'Required workflow' is a clearly sequenced 5-step process with an explicit validation checkpoint ("Build and run the relevant tests"), a reporting step, a recovery path for accidentally starting on master, and a change checklist; the CHANGELOG workflow adds a second numbered sequence with branch-reordering rules. This matches the 5 anchor (clear sequence, explicit validation, error-recovery feedback, checklist).

Progressive Disclosure

A single well-sectioned file with clear headers and no nested references; cross-skill links ([[sqlitecpp-release]], sqlitecpp-git-branching, humanizer) are one level deep and clearly signaled. Good structure with a minor gap: the ~30-line CHANGELOG conventions section is self-contained enough that it could live in a reference file, so it does not fully meet the 5 anchor's 'content appropriately split'.

Specificity

The description names the domain ("SQLiteCpp workflow") and lists several concrete work items — "branches, implementation, tests, commits, pull requests, and CHANGELOG updates" — matching the anchor for several specific actions with minor gaps (e.g., build-file updates are not surfaced in the description). Not 5 because the items are topical nouns rather than a comprehensive set of concrete actions, and not 3 because coverage clearly exceeds 1-2 actions.

Completeness

Both parts are explicit: what ("SQLiteCpp workflow for branches, implementation, tests, commits, pull requests, and CHANGELOG updates") and when ("Use when changing the repository"). The 'when' is present but could be more specific (e.g., naming the SQLiteCpp repository or common request types), matching the 4 anchor; it is not 5 because the trigger is not a set of concrete trigger phrases, and not 3 because the 'when' clause is explicit, not weakly implied.

Trigger Term Quality

Terms like "commits", "pull requests", "CHANGELOG", and "tests" are natural phrases a user would say, but the trigger clause "Use when changing the repository" is generic and common variations like "open a PR", "make a commit", or "fix a bug in SQLiteCpp" are missing. Good coverage with a few natural terms absent fits the 4 anchor better than 3 (which would miss common keywords) or 5 (which would include synonyms).

Distinctiveness Conflict Risk

The SQLiteCpp domain and workflow scope give it a clear niche with minimal conflict against general skills. Minor overlap risk remains with sibling repo skills (e.g., sqlitecpp-git-branching and the release process) because "when changing the repository" is broad, fitting the 'mostly distinct; minor overlap risk' anchor rather than the fully distinct 5.
