Conciseness

The body is dense with domain-specific, non-generic detail Claude cannot know (glob vs endpoint selector semantics, allowed_ips rules, middleware bindings), and it avoids explaining known concepts — but there is real duplication: the Quick Reference YAML patterns largely repeat the Step 5 examples, and the Step 6 hard-error checklist restates Step 4 decision rules (TLS handling, middleware constraints). This fits 'efficient; minor instances... that could be trimmed' better than 3, since the padding is confined to a couple of sections rather than scattered over-explanation, but not 5 given the ~660-line bulk with duplicated content.

Actionability

Guidance is fully executable throughout: copy-paste YAML templates for every policy shape, a concrete decision tree, a path-to-glob mapping table with exact patterns, verbatim clarifying questions to ask users, and a pre-formatted breadth-warning output block. This matches the 5 anchor ('fully executable; copy-paste ready... specific examples cover the common cases'); the 4 anchor's 'minor gaps' does not apply because even edge cases (private IPs, MicroVM identity, deny rules) get concrete examples.

Workflow Clarity

The eight-step sequence is explicit with validation built in: a clarification loop with iteration and stop conditions plus a graceful fallback for failed doc discovery (Step 2), a mandate to read the authoritative schema before generating (Step 3), and a pre-output validation checklist split into hard errors, schema warnings, and structural checks (Step 6), followed by explicit output modes and a confirm/refine step. This matches the 5 anchor — clear sequence, explicit validation checkpoints, and feedback loops for error recovery.

Progressive Disclosure

Section structure is good, but the skill ships no bundle files at all while inlining ~660 lines of content that belongs in separate reference files (the middleware rules, the breadth-warning catalog, the Quick Reference patterns), and the single body reference — 'see [examples.md](examples.md)' — points to a file that does not exist in the bundle, a dangling reference. It correctly defers schema authority to published external docs, which keeps it above the 2 anchor ('content that clearly belongs in separate files is inlined' with minimal structure), but it does not reach 4 because the one internal reference is broken and the bulk detail is inline.

Specificity

The description lists multiple concrete actions in third person — 'Generate sandbox security policies from plain-language requirements and optional REST API documentation', 'Produces L4 or fine-grained L7 network policies and ordered network middleware configuration' — covering the skill's full capability surface with no vague filler. It sits at the anchor 'lists multiple specific concrete actions; comprehensive coverage' rather than 4, since there are no noticeable coverage gaps in what the skill does.

Completeness

Both questions are answered explicitly: 'what' via 'Generate sandbox security policies... Produces L4 or fine-grained L7 network policies and ordered network middleware configuration', and 'when' via the explicit 'Use for API access rules, middleware host selection, failure behavior...' clause with concrete trigger phrases. This matches the 5 anchor ('clearly and explicitly answers both what AND when with concrete trigger phrases') and exceeds the 4 anchor where the 'when' is only broadly stated.

Trigger Term Quality

Trigger terms are comprehensive and natural, with synonym coverage users would actually say: 'generate policy, create policy, update policy, change policy, sandbox policy, network policy, API policy, security policy, allow API, restrict API, network middleware, supervisor middleware', plus a 'Use for' clause naming 'API access rules, middleware host selection, failure behavior'. Verb-variation (generate/create/update/change) matches the anchor for comprehensive natural-term coverage including synonyms, so it exceeds the 4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The niche is mostly distinct — 'sandbox policy', 'network middleware', 'L4 or fine-grained L7 network policies' clearly signal this specific domain — but generic trigger phrases like 'security policy', 'generate policy', and 'change policy' could plausibly match non-sandbox policy skills (IAM, Kubernetes, org policies), giving minor overlap risk with closely related skills. This fits the 4 anchor rather than 5, whose bar is 'minimal conflict risk' with fully distinct triggers.
