Conciseness

Prose and code are tight and assume competence, but the attribution boilerplate and six-entry related-skills promotional list add tokens that are not strictly necessary for the task; not the 5 anchor because those sections prevent 'every token earns its place', and not the 3 anchor because no basic-concept padding is present.

Actionability

Provides copy-paste-ready Node and Python verification functions, a concrete hookdeck-cli command, an env-var spec, and event/header tables covering the common cases; not the 4 anchor because the examples are fully executable rather than having minor gaps.

Workflow Clarity

The verify sequence (parse signature → HMAC over raw body → timing-safe compare → return false on failure) is clear with built-in error handling, but it is prose-and-code rather than an explicit numbered checkpoint flow; not the 5 anchor due to absent explicit validation/retry checkpoints, and not the 3 anchor because the sequence and failure handling are unambiguous.

Progressive Disclosure

SKILL.md is an overview pointing one level deep to real reference files (overview.md, setup.md, verification.md), but the body also references examples/express/, examples/nextjs/, and examples/fastapi/ paths that do not exist in the bundle; not the 5 anchor because of the dangling example paths, and not the 3 anchor because the real references are clearly signaled and well-organized.

Specificity

Lists multiple concrete actions ("Receive and verify", "setting up…handlers", "debugging Ashby-Signature verification", "handling recruiting events") plus four named events, giving comprehensive coverage; not the 4 anchor because coverage is broad rather than having only minor gaps.

Completeness

Explicitly answers both what ("Receive and verify Ashby webhooks") and when ("Use when setting up… debugging… or handling recruiting events like…") with concrete trigger phrases; not the 4 anchor because the 'when' is fully explicit and specific rather than merely adequate.

Trigger Term Quality

Includes natural terms users would say ("Ashby webhooks", "Ashby-Signature verification", "recruiting events") and exact event names (applicationSubmit, candidateHire, candidateStageChange, interviewScheduleCreate); not the 4 anchor because the named events provide comprehensive natural-keyword coverage.

Distinctiveness Conflict Risk

Clearly scoped to Ashby with provider-specific triggers (Ashby-Signature header, named Ashby events), creating a distinct niche with minimal conflict risk; not the 4 anchor because it is not merely 'mostly distinct' but provider-locked.
