Conciseness

The ~30-line body is pure signal: a 4-step usage list plus two abstraction entries with name, import, source path, and one-line description. It assumes Claude's competence, explains nothing it doesn't need to, and every token earns its place — a direct match for anchor 5 ('Lean and efficient; assumes Claude's competence').

Actionability

Each abstraction has a copy-paste-ready import statement ('import { DomainEvent } from "webiny/api/event-publisher"') and an exact source path ('@webiny/api-core/features/eventPublisher/index.ts'), and the body correctly directs the reader to the source file for the real interface. It falls short of anchor 5 only because no usage example is included — the actual API surface is delegated to the source files rather than shown.

Workflow Clarity

This is a simple single-task lookup skill well under 50 lines, so the simple-skill exception applies: the sequence (find the abstraction → read the source file for exact types → import → consult the pattern skills) is unambiguous and concretely stated. The mandatory 'You MUST read the source file' step acts as an explicit checkpoint against hallucinating interfaces, and no destructive or batch operations exist that would require validation or cap the score.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), and this skill needs none — per the rubric's simple-skill guidance, well-organized sections alone warrant a 5. The body is correctly split into 'How to Use' and 'Abstractions' with consistent per-entry structure, and pointers to implementation patterns ('webiny-use-case-pattern', 'webiny-event-handler-pattern') are clearly signaled rather than buried.

Specificity

The description 'api/event-publisher — 2 abstractions' names the domain concretely (a Webiny module path) but contains zero action verbs — it does not say what the skill does with those abstractions. It names the domain but actions are minimal to absent, fitting anchor 2 ('Names the domain but actions are minimal or generic') rather than anchor 1, since 'api/event-publisher' is a concrete domain identifier, not pure abstraction like 'Helps with documents'.

Completeness

The 'what' is extremely vague ('2 abstractions' counts entities without saying what they do) and the 'when' is entirely absent — no 'Use when...' clause or equivalent trigger guidance exists. This fits anchor 2 ('Has a vague what and no when'), not anchor 3, because the what never rises to a clear statement of function.

Trigger Term Quality

The only term present is the technical jargon path 'api/event-publisher' plus the meta-count '2 abstractions'; there are no natural keywords or synonyms a user would actually say (e.g. 'publish domain events', 'EventPublisher', 'event handler'). This matches anchor 1: 'No natural keywords; only technical jargon or entirely generic language.'

Distinctiveness Conflict Risk

The module path 'api/event-publisher' is fairly specific and not generic like 'helps with documents', but the description gives no distinguishing trigger phrases, leaving overlap risk with closely related Webiny event skills (e.g. event-handler, pub/sub, use-case patterns). It sits at anchor 3: 'Somewhat specific but could still overlap with similar skills.'
