Conciseness

The body is almost pure catalog data — names, imports, source paths — with no explanation of concepts Claude already knows, fitting 'Efficient; minor instances of over-explanation that could be trimmed'. Not a 5 because the identical import path 'webiny/api/webhooks' is repeated verbatim in all 15 entries when a single shared statement would do, and the horizontal rules between entries add pure delimiter tokens.

Actionability

Every entry supplies a copy-paste-ready import statement and an exact source file path, and the 'How to Use' steps are concrete ('You MUST read the source file', 'Import: import { Name } from "<importPath>"'), matching 'Mostly executable guidance; concrete code or commands with minor gaps'. Not a 5 because there is no usage example and 12 of 15 entries have no description, so the reader must open the source to learn what most abstractions even are.

Workflow Clarity

The skill is a single-purpose lookup catalog and the 'How to Use' sequence is unambiguous: find the abstraction, read the source for exact interfaces, import it, and consult the named pattern skills for implementation. Per the simple-skill guidance, a clear single action with an explicit numbered sequence and a MUST directive earns the top anchor; no validation loop is needed since the skill is non-destructive.

Progressive Disclosure

Structure is good: two clear sections ('How to Use', 'Abstractions') with a consistent per-entry format, and the only external pointers ('See webiny-use-case-pattern or webiny-event-handler-pattern skills') are clearly signaled and one level deep. This matches 'Good structure; most content is appropriately placed; references mostly clear; minor organization gaps' — not a 5 because the 120-line flat catalog could be split (e.g., types vs. classes) or indexed for faster lookup, and no bundle files exist to absorb reference detail.

Specificity

The description only says "api/webhooks — 15 abstractions" — it names the domain (webhooks) and a count, but states no actions at all, matching the anchor 'Names the domain but actions are minimal or generic'. It is not a 1 because the domain is concretely named rather than pure abstract language; it is not a 3 because no concrete capability (e.g., 'catalogs import paths and source locations') is expressed.

Completeness

The 'what' is reduced to a bare count ('15 abstractions') with no statement of what the skill does with them, and the 'when' is entirely missing — no 'Use when...' clause or equivalent — fitting 'Has a vague what and no when'. The missing trigger clause also caps completeness at 3 per the guidelines, and this sits below that cap anyway.

Trigger Term Quality

The only candidate keywords are "api/webhooks" and "abstractions"; there are no natural phrases a user would say (e.g., 'send a webhook', 'verify webhook signatures', 'webhook delivery'), fitting 'One or two generic keywords; missing the natural phrases users say'. Not a 3 because even the common variations ('webhook', 'webhooks', 'HTTP callbacks') are absent.

Distinctiveness Conflict Risk

"api/webhooks — 15 abstractions" points at a fairly specific niche (webhook abstractions in the api namespace), so it is not broadly generic, but a bare domain label could overlap with other webhook-related or api-catalog skills. This fits 'Somewhat specific but could still overlap with similar skills' rather than 4, since no distinct trigger phrases separate it from neighbors.
