Conciseness

Mostly efficient and code-heavy, but includes unnecessary material: "Conftest is a CLI that uses OPA…" explains what Claude already knows, the "When to use" section restates the description, the "bdd-step-library-curator in the qa-bdd plugin" tangent is irrelevant, and version pins ("v0.50.0", "actions/checkout@v5") sit in the main flow rather than a deprecation/notes section. Not 4: there is more than minor trimming to do; not 2: the bulk of the body is dense, directly usable content.

Actionability

Nearly everything is executable: brew/curl installs, complete Rego policies, "conftest test manifests/ --policy ./policies/", the helm pipe, "opa test policies/", and full CI YAML. Not 5: the Step 1 curl URL contains a literal "<version>" placeholder and the Step 9 ConstraintTemplate is a truncated skeleton ("# Same Rego from Step 2") rather than copy-paste ready.

Workflow Clarity

Steps 1–9 are clearly sequenced from install through CI to Gatekeeper, with validation checkpoints (dedicated policy-testing step 7, "opa test policies/" gating before conftest in CI) and negation-test guidance in the anti-patterns table. Not 5: there is no explicit error-recovery loop (what to do when conftest fails) — validation is present but the validate→fix→retry feedback loop is implicit.

Progressive Disclosure

No bundle files exist; the single SKILL.md is well organized with numbered steps, an anti-patterns table, limitations, and a clearly signaled one-level-deep References section of external links. Not 5: at ~245 lines the per-target policy examples (Kubernetes/Terraform/Dockerfile) are all inline and could be split into per-domain reference files; not 3: structure and navigation are clear, not buried.

Specificity

Lists multiple concrete actions — "Writes OPA Rego policies and runs Conftest against Kubernetes manifests, Terraform plans, Dockerfiles or any structured data; also covers Cedar" — with comprehensive coverage of the skill's domain. Not 4: the action list has no notable coverage gaps.

Completeness

Explicitly answers both: what — "Writes OPA Rego policies and runs Conftest against…"; when — "Use when a team needs custom policies that off-the-shelf scanners don't cover (cost limits, required tags, security baselines) enforced in CI", with concrete trigger conditions. Not 4: the 'when' clause is specific and trigger-phrase-rich, not merely present.

Trigger Term Quality

Good natural keyword coverage: "cost limits", "required tags", "security baselines", "CI", "OPA Rego", "Conftest", "Kubernetes manifests", "Terraform plans", "Dockerfiles". Not 5: the most natural user phrase "policy as code" and common variants like "OPA Gatekeeper"/"admission control" are missing.

Distinctiveness Conflict Risk

Mostly distinct: it explicitly carves out "custom policies that off-the-shelf scanners don't cover", separating it from generic scanner skills. Not 5: "security baselines enforced in CI" and the Cedar mention still carry minor overlap risk with closely related scanning/policy skills.
