Conciseness

The body avoids concept over-explanation, but every endpoint carries a redundant label line (e.g. "GET webhooks › <id>") duplicating its heading, the Overview repeats the description verbatim, and `-d '{}'` placeholders add tokens without information. This matches the 'mostly efficient but could be tightened' anchor rather than 4, since the duplication is systematic across all eight endpoints rather than a minor instance.

Actionability

GET/DELETE curl commands are copy-paste executable with real host and auth headers, but the core write operations (POST create, PUT update) send `-d '{}'` with no example payload fields (url, events), and request schemas are outsourced to an external OpenAPI spec. This matches the 'concrete guidance but incomplete, missing key details' anchor; the gap is not minor since registering a webhook cannot be done from this document alone.

Workflow Clarity

The content is an endpoint catalog with no sequencing (e.g. validate-url → register → test → check deliveries) and no verification step before the destructive DELETE /api/webhooks/{id}, which per the guidelines caps workflow clarity at 3. It is not a 2 because each individual operation is unambiguous and coherently organized.

Progressive Disclosure

Sections (Overview, Authentication, Endpoints, Payloads) are well organized and the payload detail is delegated via one clearly signaled pointer ("See the full OpenAPI specification at `GET /api/openapi/spec` or `docs/openapi.yaml`"), matching the good-structure anchor. It is not a 5 because the referenced OpenAPI document is external to the skill bundle, so navigation dead-ends within the shipped skill.

Specificity

The description lists multiple concrete actions spanning the full lifecycle — "Register, list, test, and remove webhook endpoints" plus "Configure event subscriptions (request.completed, request.failed, quota.exceeded, etc.)" and "manage delivery retries" — which matches the comprehensive-coverage anchor. It is not a 4 because the action list goes beyond 'several actions with minor gaps' to cover create, read, update, delete, testing, subscription configuration, and retry management.

Completeness

The 'what' is clearly and concretely answered, but there is no 'Use when...' clause or equivalent trigger guidance, which per the judging guidelines caps completeness at 3. It is not a 2 because the 'what' is specific and multi-faceted rather than vague.

Trigger Term Quality

"webhook endpoints", "event subscriptions", and "delivery retries" are natural phrases users would say, reinforced by concrete event names (request.completed, quota.exceeded), giving good keyword coverage. It falls short of the 5 anchor because common synonyms and variations like "callbacks", "notifications", or "HTTP endpoints" are absent.

Distinctiveness Conflict Risk

Webhook management with product-specific event names (request.completed, quota.exceeded) forms a clear niche with mostly distinct triggers. It is not a 5 because generic terms like "webhook endpoints" could overlap with webhook skills for other services or APIs.
