Conciseness

The body is largely command-driven and practical, but includes fluff Claude does not need: the vacuous line 'Use action names and parameters as needed', the vague and ungrammatical 'Agent Types' note ('Those will be used to adjust tooling to be used best with your harness'), and editorial padding like 'so you can focus on the integration logic rather than auth plumbing'. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation that could be tightened') rather than 4, whose over-explanation is only minor.

Actionability

Concrete, executable CLI commands appear throughout with placeholders and a flags table (install, login, connection ensure, action list/run, request proxy), e.g. 'membrane action run <actionId> --connectionId=CONNECTION_ID --input {...} --json'. Minor gaps keep it below 5: the 'Step 2' referenced in 'skip to Step 2' does not exist, the intent example is the placeholder 'QUERY' with no worked example, and 'Popular actions' promises a list but only repeats the discovery command.

Workflow Clarity

The flow (install → login → connection ensure → poll state → handle clientAction → search actions → run/proxy) is clearly sequenced with explicit checkpoints and a feedback loop: poll with --wait, branch on READY/CLIENT_ACTION_REQUIRED/CONFIGURATION_ERROR, re-poll after user action, check the error field. Not 5 because the step numbering is broken — 'Step 1' and 'Step 2' are referenced but never labeled (only '1b' exists), leaving the reader to guess where the connection phase ends and action execution begins.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so the skill is a single self-contained file with well-organized sections, clear headers, and one-level navigation — good structure with most content appropriately placed (anchor 4). It falls short of 5 only because material like the proxy flags table and connection-state details could live in a reference file if the skill grows, and 'Assembled Overview' bullets ('Project — Task — Attachment') carry no navigational value.

Specificity

The description names the domain ('Assembled integration') but its actions are generic: 'Manage data, records, and automate workflows' could describe nearly any integration and lists no concrete Assembled capabilities (e.g., forecasting, scheduling, agent management). It matches anchor 2 ('Names the domain but actions are minimal or generic') better than 3, which requires 1-2 concrete actions.

Completeness

It does have an explicit 'when' clause ('Use when the user wants to interact with Assembled data'), so it avoids the missing-trigger cap of 3, but the 'what' is vague ('Manage data, records, and automate workflows'), placing it at anchor 3 rather than 4 — anchor 4 expects both a reasonably concrete 'what' and a 'when'.

Trigger Term Quality

The only substantive keyword is the product name 'Assembled'; 'data', 'records', and 'workflows' are generic. Common natural phrases a support-ops user would say — scheduling, forecasts, staffing, WFM, support tickets — are entirely absent, matching anchor 2 ('one or two generic keywords; missing the natural phrases users say').

Distinctiveness Conflict Risk

'Assembled' is a distinctive product name and the trigger is tied to it, but the description never states what Assembled is (workforce management for support teams), and the generic 'manage data, records, automate workflows' framing overlaps with any data/records integration skill — 'somewhat specific but could still overlap with similar skills' (anchor 3), not 4's 'minor overlap risk'.
