Conciseness

The intro paragraph ("Acunetix is a web application security scanner used to identify vulnerabilities like SQL injection and XSS...") explains concepts Claude already knows, the "Acunetix Overview" section is a content-free noun list, and action-list syntax is documented twice with inconsistent forms ("membrane action list --intent QUERY" vs "npx @membranehq/cli@latest action list --intent=QUERY"). The bulk is efficient command documentation, which keeps it above 2, but the redundant and padded material sits firmly at 3 rather than 4.

Actionability

Nearly all guidance is copy-paste executable: install command, login flow with headless variant, `membrane connection ensure`, `action run` with `--input` JSON, and a proxy flags table. Not 5 because placeholders like <actionId> are never instantiated with a real Acunetix example (e.g., launching a scan or fetching a report); not 3 since nothing shown is pseudocode or abstract.

Workflow Clarity

The install → auth → connect → discover → run/proxy sequence is clear and includes explicit state-based checkpoints (READY, CLIENT_ACTION_REQUIRED, CONFIGURATION_ERROR) with a re-poll loop after user action. Not 5 because "skip to **Step 2**" references a step that is never defined or labeled; not 3 since connection-state validation is explicit and well-handled.

Progressive Disclosure

The skill has no bundle files and the single-file body is well-sectioned with headers and flat, one-level navigation. Not 5 because at ~140 lines the proxy flag table and connection-state reference detail could be split out, and "Popular actions" structurally duplicates "Searching for actions"; not 3 since organization is clean and nothing is buried.

Specificity

"Manage data, records, and automate workflows" is generic boilerplate that names the Acunetix domain but lists no concrete actions such as managing scan targets, launching scans, or retrieving vulnerability reports. Not 1 because the domain is named; not 3 because not even one concrete, app-specific action is stated.

Completeness

Both elements are explicitly present: a "what" ("Manage data, records, and automate workflows") and a "when" ("Use when the user wants to interact with Acunetix data"), written in third person. Not 5 because the "what" is shallow and generic rather than concrete; not 3 because the "when" clause is explicit and specific.

Trigger Term Quality

The only natural trigger is the app name itself ("Acunetix", "Acunetix data"); common user phrases like "vulnerability scan", "web application security scan", or "scan report" are absent. Not 2 because "Acunetix" is a specific, non-generic keyword; not 4 because coverage lacks synonyms and variations.

Distinctiveness Conflict Risk

"Acunetix" is a clear niche trigger with minimal conflict risk, but the generic "manage data, records, and automate workflows" phrasing could overlap with other Membrane app-integration skills sharing the same boilerplate. Not 5 due to that overlap risk; not 3 because the app name alone makes it largely distinguishable.
