Conciseness

The body repeats each core rule two to three times: a literal duplicate '## Mindset' section appears at both the top and bottom, the '## Never' section restates Mindset and Query construction rules, and '## Anti-Patterns' restates 'Never' and 'Handling no results' almost verbatim. This is 'noticeably verbose; several unnecessary… padded sections' (anchor 2) — not 3, because roughly a third of the sections are pure restatement rather than isolated tightening opportunities.

Actionability

Fully executable, copy-paste-ready guidance: exact CLI syntax with flags ('vault-cli search "<query>" [--top-k <n>] [--project <id>]'), explicit exit behavior ('Exits 1 with "No results."'), four concrete example commands covering plain, project-scoped, top-k, and error-message queries, plus a sample output format. Matches anchor 5: examples cover the common cases.

Workflow Clarity

The workflow is clearly sequenced with an explicit feedback loop: construct a noun-phrase query → run the search → on empty, 'Retry with a broader synonym query' → if still empty, report honestly and 'Never invent or guess at a prior decision'. The exit-1/'No results.' signal serves as the validation checkpoint, matching anchor 5's 'feedback loops for error recovery'; this is a non-destructive single-command skill so no validation cap applies.

Progressive Disclosure

Good structure with a well-signaled, one-level-deep reference ('[Vault Search: Query Tips](references/query-tips.md)' — a real file) and clear section headers. Not 5: the duplicate '## Mindset' section and the overlap between the body's 'Query construction' section and the reference file's content ('Use concrete nouns from the task, not the literal user phrasing' appears in both) are minor organization gaps — anchor 4's 'most content is appropriately placed' with 'minor organization gaps'.

Specificity

The description names the domain ('persistent memory') and one concrete action ('Search persistent memory for relevant context'), with specific search targets ('architectural decisions, resolved bugs, and implementation patterns'), but only a single action verb is ever listed. It matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') rather than 4, which requires several distinct actions.

Completeness

Explicitly answers both: 'what' ('Search persistent memory for relevant context — including architectural decisions, resolved bugs, and implementation patterns') and 'when' via multiple when-clauses plus an explicit 'Use when the user says…' with concrete trigger phrases. This is a direct match for the anchor-5 example pattern.

Trigger Term Quality

Comprehensive natural-term coverage including direct quotes of user phrasing ('do you remember…', 'what did we decide about…', 'have we solved this before') plus paraphrased triggers ('past decisions', 'recurring issue', 're-implementing something that may have been done before'). These synonyms span the recall/past-context domain; not level 4 because no common variation of this intent is conspicuously absent.

Distinctiveness Conflict Risk

Clear niche (persistent-memory recall) with distinct quoted triggers, but the proactive triggers ('when uncertain whether something was already decided, or before re-implementing something that may have been done before') are broad and could fire on many tasks, creating minor overlap with other pre-task skills. Mostly distinct with minor overlap risk — anchor 4, not 5.
