Conciseness

The body is dominated by executable commands and compact tables, with only minor trimmable filler ("Use action names and parameters as needed.", the intro sentence about salons/therapists/consultants, and the awkward "Agent Types" aside). This fits 'efficient; minor instances of over-explanation that could be trimmed' better than score 3, since the unnecessary material is only a few short lines across ~180 lines.

Actionability

Every stage has copy-paste-ready commands: `npm install -g @membranehq/cli@latest`, `membrane login complete <code>`, `membrane connection ensure "https://www.acuityscheduling.com/" --json`, `membrane action list --connectionId=CONNECTION_ID --intent "QUERY" --limit 10 --json`, and `membrane action run <actionId> --input '{"key": "value"}' --json`, plus a 20-row popular-actions table and a proxy fallback with a full flag table. Fully executable guidance covering the common cases — matches the anchor 5 example; nothing significant is missing for score 4.

Workflow Clarity

The connection workflow has a clear sequence with genuine feedback loops (poll `--wait` while BUILDING, handle `clientAction`, re-poll after user auth, check `error` on CONFIGURATION_ERROR/SETUP_FAILED). However, "If the returned connection has `state: "READY"`, skip to **Step 2**" references a step label that doesn't exist, the heading "1b" belongs to a numbering scheme never established, and `membrane connection get` vs `npx @membranehq/cli connection get` are used inconsistently. Most importantly, destructive operations in the actions table (Cancel Appointment, Delete Client, Delete Block) have no validation/verification steps, which per the rubric caps this dimension at 3.

Progressive Disclosure

This is a single-file skill with no bundle files present; sections are well-organized (Install, Authentication, Connecting, Searching, Popular actions, Running, Proxy, Best practices) and easy to navigate. The ~20-row Popular actions table and the detailed connection-state handling are inline reference material that could move to a separate file, which keeps it below anchor 5, but placement is defensible for a CLI skill of this size — matching 'good structure; most content is appropriately placed; minor organization gaps' (4) rather than 'content that should be separate is inline' (3).

Specificity

"Manage Calendars, Clients, Users, Forms, Packages, Coupons" enumerates six concrete resource capabilities, which goes beyond anchor 3's '1-2 concrete actions', but the coverage gap is larger than 'minor' — it omits appointments/booking, the app's core function (the body itself lists Appointment, Appointment Type, Class, Gift Certificate, Subscription, Report). Falls between anchors 3 and 4, noticeably above the midpoint.

Completeness

Both parts are present: the what ("Acuity Scheduling integration. Manage Calendars, Clients, Users, Forms, Packages, Coupons.") and an explicit when ("Use when the user wants to interact with Acuity Scheduling data."). The when clause is explicit but circular — it restates the app name rather than giving concrete trigger phrases like 'appointments' or 'bookings', so it matches anchor 4 ('when' could be more explicit or specific) rather than anchor 5.

Trigger Term Quality

Good keyword coverage: "Acuity Scheduling" (the strongest natural trigger), plus "Calendars", "Clients", "Users", "Forms", "Packages", "Coupons". However, it misses the most natural phrases a user would say — "appointments", "bookings", "reschedule", "availability" — keeping it below anchor 5's 'comprehensive coverage including synonyms'.

Distinctiveness Conflict Risk

"Acuity Scheduling integration" and "interact with Acuity Scheduling data" are anchored to a specific named app, giving a clear niche with distinct triggers and minimal conflict risk — even though generic words like Calendars/Clients appear, they are framed entirely within the Acuity context, so overlap with calendar or CRM skills is minimal.
