Conciseness

The body is dense and assumes Claude's competence — exact config keys, terse rules, no padding about what auditing is. It falls to anchor 4 rather than 5 because of time-sensitive inline inventory ('The `admins` events today: default model (`agent-default-model`), app member roles, app permission roles...') that will rot, and a Settings-page paragraph that partially duplicates the action reference; per the rubric's time-sensitivity guideline this penalizes conciseness.

Actionability

Fully executable, copy-paste-ready guidance throughout: complete defineAction code with real audit fields, a named import path ('@agent-native/core/audit') with both action and Nitro-route usage, exact override flags ('audit: { onRead: true }', 'recordInputs: false'), concrete filter/paging semantics for each read action, and exact env vars (AGENT_NATIVE_AUDIT_RETENTION_DAYS, AGENT_NATIVE_AUDIT_ENABLED). The only elided code (the run body) is app-specific and its omission is justified.

Workflow Clarity

This is a reference/config skill rather than a multi-step pipeline, and it contains no destructive or batch agent operation, so the validation cap does not apply. Each task has unambiguous guidance (defaults, override flags, helper functions for org settings, named read actions, an explicit 'Never' checklist), matching anchor 4; it stops short of 5 only because the sections are parallel guidance rather than a sequenced workflow with explicit checkpoints.

Progressive Disclosure

The skill is a single self-contained file (no references/, scripts/, or assets/ exist) with clear section headers, no nested or buried references, and easy in-file navigation — matching anchor 4. It is not a 5 because reference-grade inventory (the visibility table, the enumerated admins event types, the full filter API) is inlined where a separate reference file could keep SKILL.md leaner, though at ~150 lines the single-file choice is defensible.

Specificity

The description concretely defines the capability ('Durable, access-scoped, append-only record of who changed what app data, when') and the use-when clause enumerates specific tasks (activity feed, change history, declaring targets, auditing sensitive reads). It sits at anchor 4 rather than 5 because the 'what' is a single well-formed definition rather than a list of multiple discrete operations, and above 3 because coverage of capability and use cases is broad and concrete.

Completeness

Both halves are explicit: the 'what' is a clear, concrete definition of the record, and the 'when' is an explicit 'Use when...' clause with concrete trigger phrases including a verbatim user question. This matches the anchor-5 example pattern exactly.

Trigger Term Quality

Natural phrases users would actually say are present: 'activity feed', 'change history', 'what did the agent change / who edited this', 'auditing sensitive reads'. This matches anchor 4 — good keyword coverage but missing common synonyms such as 'audit trail' or 'change log' that would earn a 5.

Distinctiveness Conflict Risk

Terms like 'audit', 'activity feed', and 'who edited this' carve a distinct niche with minimal conflict risk, but the description borders on product-analytics/tracking territory without signaling that boundary, so anchor 4 ('mostly distinct; minor overlap risk with closely related skills') is the best fit rather than 5.
