Conciseness

The body is mostly efficient concrete commands with only minor over-explanation (the opening 'Control D is a customizable DNS service...' paragraph and the awkward Agent Types line), fitting the 'efficient; minor instances of over-explanation that could be trimmed' anchor.

Actionability

It provides fully executable, copy-paste-ready commands throughout (npm install, membrane login, connection ensure/get with --json, action list/run, request with a concrete flags table), covering the common cases with specific examples.

Workflow Clarity

The connection setup has a clear sequence with explicit state-based validation checkpoints and feedback loops (poll --wait, CLIENT_ACTION_REQUIRED -> user acts -> poll again, CONFIGURATION_ERROR -> check error field); the dangling 'skip to Step 2' reference and unlabeled step numbering are minor gaps keeping it just below 5.

Progressive Disclosure

No bundle files exist and all content lives in one file, but it is well-organized into clearly headed sections (overview, install, auth, connecting, searching, running, proxy, best practices) with no deep nesting or buried references; structure is good with only minor organization gaps, consistent with the well-organized-sections allowance for self-contained skills.

Specificity

It names the domain ("Control D integration") but the actions "Manage data, records, and automate workflows" are generic rather than concrete, matching the 'names domain but actions minimal/generic' anchor and falling short of listing specific capabilities.

Completeness

Both 'what' ("Manage data, records, and automate workflows") and an explicit 'when' ("Use when the user wants to interact with Control D data") are present; the 'Use when' clause avoids the cap at 3, but the trigger is generic and could be more specific, fitting the both-present-but-when-could-be-sharper anchor.

Trigger Term Quality

It includes the distinctive keyword "Control D" and the phrase "interact with Control D data", but misses the natural task terms a user would actually say (DNS, block ads/trackers/malware, DNS filtering), so keyword coverage has relevant terms with common synonyms missing.

Distinctiveness Conflict Risk

The "Control D" brand name creates a clear niche with distinct triggers and minimal conflict risk with other skills, matching the 'clear niche with distinct triggers' anchor.
