Conciseness

The body is ~25 lean lines of pure directives ("Use `host.docker.internal` for host-side services from inside Plano container", "Prefer PostgreSQL state storage for production multi-turn workloads") with zero padding and no explanation of concepts Claude already knows. Matches the anchor "Lean and efficient; assumes Claude's competence; every token earns its place"; there is nothing to trim and no over-explanation to demote it.

Actionability

Items name concrete values (`host.docker.internal`, PostgreSQL, `/healthz`) but stop short of executable guidance — no commands, config snippets, env var names, or connection settings for PostgreSQL state or secret handling. Additionally, "Apply These Rules: `deploy-docker`, `deploy-state`, `deploy-health`" points to rule content that does not exist anywhere in the bundle. This is "some concrete guidance but incomplete; missing key details" rather than "mostly executable".

Workflow Clarity

The numbered Execution Checklist gives a clear sequence with an explicit checkpoint ("Verify `/healthz` before traffic or CI assertions") and a diagnostics step ("Return deployment checks with failure-mode diagnostics"). Not 5 because there is no error-recovery loop (what to do when the health check fails) and the referenced rules inject undefined steps into the sequence; not 3 because a checkpoint is explicitly present, not implicit.

Progressive Disclosure

Sections (When To Use, Apply These Rules, Execution Checklist) are well organized for a short skill, but the body references `deploy-docker`, `deploy-state`, and `deploy-health` rules and no references/, scripts/, or assets/ directories or rule files exist in the bundle — the references are dangling with no resolvable path. This lands at "some structure but could be better organized; references present but not clearly signaled" rather than 4, since the primary navigation to the actual rule content is broken.

Specificity

"Apply Plano deployment and production security practices. Use for Docker networking, state storage choices, readiness checks, and environment-based secret handling" names the domain and several concrete practice areas. Not 5 because the actions are application areas rather than distinct concrete actions (anchor-5 example lists discrete operations like "extract text... fill forms... merge documents"); not 3 because coverage goes well beyond 1-2 actions.

Completeness

Both parts are present: a "what" ("Apply Plano deployment and production security practices") and an explicit "when" clause ("Use for Docker networking, state storage choices, readiness checks, and environment-based secret handling"). Not 5 because the "what" is generic ("apply practices") compared to the anchor-5 example, which pairs concrete actions with explicit trigger phrases; not 3 because the "when" is explicit, not merely implied.

Trigger Term Quality

Terms like "Docker networking", "state storage", "readiness checks", and "environment-based secret handling" are phrases users would naturally say when needing this skill. Not 5 because common synonyms such as "health checks", "production hardening", "Postgres", or "secrets" are missing; not 3 because coverage of natural terms is good, not just partial.

Distinctiveness Conflict Risk

Scoping to "Plano" deployment gives it a clear niche unlikely to trigger for unrelated skills. Not 5 because the trigger terms themselves (Docker networking, state storage, readiness checks, secret handling) are generic deployment vocabulary that overlaps with general Docker/ops skills; not 3 because the Plano anchoring makes significant overlap unlikely.
