Conciseness

The body is dense with repo-specific facts Claude would not know (module import paths, exact error strings like "secret value is not a string", fixture expectations) and assumes competence rather than explaining Caddy or secrets concepts. It is not score 5 because sections like "Validation Notes" and "Fixtures" run long on test-internals detail that could be trimmed or pushed to a reference; it is clearly above score 3, which requires noticeably unnecessary explanation.

Actionability

Guidance is fully executable throughout: complete Caddyfile blocks for each manager shape, copy-paste authdbctl commands ("authdbctl generate password hash --cost 10 --password SomeFunkyPassword"), exact lookup syntax "secrets:<secret_id>:<key>", and concrete failure modes with their literal error messages. Examples cover the common cases (static users, AWS region/path, bcrypt hashing, API keys).

Workflow Clarity

The sections sequence a coherent configuration flow (shape → per-manager setup → lookup wiring → hash generation → validation/fixtures), and validation checkpoints are substantively addressed (strict three-field resolution, missing-manager/key provisioning failures, fixture error expectations, reload/recovery behavior). It misses score 5 because steps are not explicitly enumerated with validate-and-retry loops — checkpoints are described narratively rather than as an ordered procedure with feedback cycles.

Progressive Disclosure

The bundle structure is used well: both references/consul.md and references/sqlite.md exist and are clearly signaled one level deep ("use the [Consul secrets reference](references/consul.md)"), with the runtime-resolution boundary delegated to a sibling skill. It falls short of score 5 because the static and AWS manager sections plus the ~45 lines of test-fixture notes are fully inlined in SKILL.md, an organization inconsistency against the pattern established by the SQLite/Consul references.

Specificity

"Configure security.secrets plugins and secret lookup values for users, credentials, and crypto" names the domain and concrete actions, and "SQLite/Consul provisioning, static/AWS wiring, and lookup failures" enumerates specific scenarios and manager types. It stops short of score 5 because coverage has minor gaps (e.g., generated hash values and validation behavior appear in the body but not the description), and is well above score 3's '1-2 concrete actions' bar.

Completeness

Both halves are explicit: the 'what' is "Configure security.secrets plugins and secret lookup values for users, credentials, and crypto" and the 'when' is "Use for SQLite/Consul provisioning, static/AWS wiring, and lookup failures" with concrete trigger phrases. It even adds a boundary clause ("runtime field support belongs to runtime resolution"), which the score-4 anchor lacks in explicitness.

Trigger Term Quality

Natural trigger phrases users would say in this niche are present: "SQLite/Consul provisioning", "static/AWS wiring", "lookup failures", "credentials". It falls short of score 5's comprehensive synonym coverage — variants like "secret manager", "password hash", or "bcrypt" that the body covers are absent from the description.

Distinctiveness Conflict Risk

The description occupies a clear niche (Caddy/authcrunch security.secrets plugin configuration) with distinct triggers, and the boundary clause "runtime field support belongs to runtime resolution" explicitly disambiguates it from the closely related runtime-resolution skill. Minimal conflict risk, matching the score-5 anchor.
