Conciseness

The operational core is dense and non-obvious (e.g., "isCloudHub must be null (not false)", the flat-vs-nested deployment body, getExchangePolicyTemplates vs listPolicyTemplates), but there is noticeable padding: seven "What happens next:" narrative bridges, the celebratory "What You've Built" section, generic "Next Steps" advice, and the same getExchangePolicyTemplates caveat repeated in Step 6, Step 7's common issues, and Tips/Gateway Compatibility. This matches 'Mostly efficient but includes some unnecessary explanation or could be tightened'; not a 4 because the padding spans multiple whole sections rather than minor instances.

Actionability

Every step ships a complete executable operation spec (api, operationId, inputs with sources/examples, outputs with JSON paths), plus a concrete request body ("Use flat top-level fields, not the nested target object" with the JSON example) and exact error-message-to-fix mappings ("'Field environmentId is required for deployment type HY'... must be in the request body, not just the URL path"). This matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

The 7-step sequence is explicit with three named execution paths ("Full setup: Steps 1, 2, 3, 4, 5, 6, 7" / "From Exchange asset" / "Apply policy only"), a flowchart, per-step variable wiring ("from: variable: environmentApiId"), a Completion Checklist for verification, and feedback loops for error recovery (409 → "List existing deployments with GET .../deployments first to check"; 400 → use getExchangePolicyTemplates). This matches 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and the body is a single well-sectioned file with clear headers, flowcharts, and a "Related Jobs" section. Structure matches 'Good structure; most content is appropriately placed; minor organization gaps'. Not a 5 because there are no one-level-deep reference files at all — the ~80-line Troubleshooting and Tips sections could be split out of the already-long main file; not a 3 because navigation is clear and nothing is buried.

Specificity

Quotes: "Secure an API by applying a policy from the catalog", "add rate limiting, apply OAuth2, enforce IP allowlisting" — several concrete, distinct actions are named, matching the anchor 'Lists several specific actions; minor gaps in coverage'. Not a 5 because the description omits significant capabilities the skill covers (creating an API Manager instance, deploying to a gateway), leaving gaps in coverage; not a 3 because more than 1-2 actions are concretely listed.

Completeness

Quotes: what — "Secure an API by applying a policy from the catalog. Handles multiple starting points: from an existing API Manager instance, from an Exchange asset... or from scratch"; when — "Use when the user wants to secure an API, add rate limiting, apply OAuth2, enforce IP allowlisting, or protect any API with a policy". Both what and when are explicit with concrete trigger phrases, matching the anchor 'Clearly and explicitly answers both what AND when with concrete trigger phrases'.

Trigger Term Quality

Quotes: "secure an API", "add rate limiting", "apply OAuth2", "enforce IP allowlisting", "protect any API with a policy" — these are natural phrases a user would say, matching 'Good keyword coverage; a few natural terms missing'. Not a 5 because common synonyms like 'throttling', 'API gateway', or 'authentication' are absent; not a 3 because coverage goes well beyond a couple of generic keywords.

Distinctiveness Conflict Risk

Quotes: "applying a policy from the catalog", "from an existing API Manager instance, from an Exchange asset" — a clear niche (API policy management on a specific platform) with distinct triggers, matching 'Mostly distinct; minor overlap risk with closely related skills'. Not a 5 because phrases like 'apply OAuth2' or 'rate limiting' could also match generic API-security skills; not a 3 because the policy/instance framing is well differentiated.
