Conciseness

The body is dense with project-specific operational knowledge Claude cannot know (checksum-based de-dup, tag prefix matching at reduced strength, prune verdict protocol, per-store citation rules) and contains no basic-concept padding. Minor over-explanation could be trimmed: the audit's propose-then-confirm rule is restated roughly four times (steps 4 and the note at the end of the audit section, then again twice in Decline handling), and the tag-form philosophy paragraphs are discursive. Efficient with minor trimmable instances — anchor 4, not 5; not 3 because almost every sentence carries a non-obvious specific.

Actionability

Every intent supplies copy-paste-ready invocations: `spektacular knowledge search <query>` with exact flag semantics, `write --data '{"tier":…,"name":…,"path":…}' --file …`, the staged-file format with a concrete frontmatter example, the `rm` cleanup, and the prune verdict command with full JSON. Specific examples cover the common cases, matching the fully-executable anchor.

Workflow Clarity

Each of the five intents is a clearly numbered sequence with explicit checkpoints and error feedback: the audit's per-entry confirmation gate ("an audit write without explicit user approval is a bug"), prune's dry-run preview, evidence-required verdicts with refusal messages that say how to fix them, resumability, and the CLI-refusal feedback on writes. The destructive/batch cap does not apply because validation is present throughout, so this matches the anchor with explicit validation, feedback loops, and fallbacks (e.g. inline consolidation when no sub-agent can spawn).

Progressive Disclosure

No bundle files exist, and the single file is well organized: an overview section, a "When to invoke" section with concrete trigger phrases, and one clearly headed section per intent. Shared material (the tag-form rules) is cross-referenced rather than restated ("Apply the Choosing tag forms rules from the contribute intent unchanged — do not restate"), but at ~150 lines the tag-form rules and lookup consolidation contract are shared by multiple intents and could live one level deep in a reference file. Good structure with minor organization gaps — anchor 4, not 5.

Specificity

"Search, contribute to, or update the project's knowledge base" names the domain and a few actions, but the verbs are generic ("contribute to" names no concrete operation like write/record/tag) and two of the body's five intents (audit, prune) are absent, which is more than a minor coverage gap. It sits between anchor 3 and 4, closer to 3: more than 1-2 actions listed, yet not the specific, comprehensive action list of 4.

Completeness

The "what" is clear (search/contribute/update the project's knowledge base) but there is no "Use when…" clause or any equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. Not 2 because the "what" is specific and the domain implies a weak "when"; not 4 because the "when" is not explicit at all.

Trigger Term Quality

Relevant keywords are present ("search", "knowledge base", "update", "contribute") but common natural phrasings users would actually say are missing — "look up", "remember", "recall", "entry", "notes" — matching the "some relevant keywords but missing common variations or synonyms" anchor. Not 4 because coverage of natural terms is thin rather than good-with-a-few-missing.

Distinctiveness Conflict Risk

"The project's knowledge base" names a specific artifact, giving the skill a clear niche with distinct triggers, but no tool identifier (e.g. Spektacular) is given, leaving minor overlap risk with generic memory/notes-type skills. Mostly distinct with minor overlap, matching anchor 4; not 5 because it does not fully disambiguate from closely related knowledge-management skills.
