Conciseness

The body is mostly efficient command blocks, but contains unnecessary padding: a marketing-style intro ("It's used by businesses and individuals to streamline booking appointments, meetings, and events"), the filler line "Use action names and parameters as needed", the same `action list` command shown twice (once as `membrane`, once as `npx`), and a "Popular actions" section that lists no actions. This fits 'Mostly efficient but includes some unnecessary explanation or could be tightened' — below 4 because the duplication and empty section are clearly trimmable.

Actionability

Concrete, copy-paste-ready CLI commands appear throughout (install, login, connection ensure, poll with --wait, action list/run with --input JSON, proxy flags table). Minor gaps keep it below 5: "skip to Step 2" references a step that is never defined, and the "Popular actions" heading contains no actual example actions with IDs or inputs.

Workflow Clarity

A clear sequence runs install → login → connection ensure → poll --wait → handle clientAction states → search actions → run → proxy fallback, with explicit state checkpoints (READY, CLIENT_ACTION_REQUIRED, CONFIGURATION_ERROR/SETUP_FAILED) and a re-poll feedback loop. Below 5 because the step numbering is incoherent — "1b" exists without a labeled Step 1, and "Step 2" is referenced twice but never defined.

Progressive Disclosure

As a single-file skill with no bundle files, content stays one level deep with clear section headers (Install, Authentication, Connecting, Searching, Running, Proxy, Best practices) — good structure with content appropriately placed. Below 5 due to minor organization gaps: the entity bullet list under "Calendso Overview" carries no purpose, and the empty "Popular actions" section adds navigation noise.

Specificity

"Manage data, records, and automate workflows" names the Calendso domain but the actions are generic; no concrete capabilities like booking, availability, or event-type management are listed. This matches the anchor 'Names the domain but actions are minimal or generic' — above 1 because the domain is named, below 3 because no specific concrete action is described.

Completeness

Both parts are present: what ("Calendso integration. Manage data, records, and automate workflows") and an explicit when ("Use when the user wants to interact with Calendso data"). It is above 3 because the 'when' is explicitly stated rather than missing, but below 5 because both the what and when remain generic and could be more specific with concrete trigger phrases.

Trigger Term Quality

The only natural keyword is "Calendso" (repeated); phrases like "manage data, records" and "automate workflows" are generic. Users would naturally say "scheduling", "booking", "appointments", "meetings", or "Cal.com" — none appear, matching 'One or two generic keywords; missing the natural phrases users say'.

Distinctiveness Conflict Risk

The Calendso name gives it a clear, distinct niche and the trigger explicitly names Calendso, so it is unlikely to fire for the wrong skill. Below 5 because the generic middle sentence ("Manage data, records, and automate workflows") creates minor overlap risk with other data-integration skills.
