Conciseness

The body is dense and almost entirely non-obvious, product-specific contract detail (identity-binding rules, SMB share semantics, pagination conventions, provenance markers) with almost no explanation of concepts Claude already knows. It falls short of anchor 5 due to repetition — the never-bypass-the-gateway/arbitrary-HTTP rule appears three times (lines 128-131, 245-246, 386-387) and the never-repeat-an-unknown-write rule is stated three times (172, 311, 334-338) — and host-agent bookkeeping sections ("Reusable learning", session/memory tools) that pad the routing guide.

Actionability

Guidance is fully executable: copy-paste gateway call shapes in JSON ("{\"operation_id\":\"media.search\",\"path_params\":{},\"query\":{\"title\":\"The Wandering Earth\",\"type\":\"media\"},\"body\":{}}"), a table of exact parameter contracts for common reads/downloads, explicit field-placement rules (path_params vs query vs body), and a defined error-feedback contract ("an invalid_input response names the failing field and includes input_contract; correct that field... before retrying"). This matches anchor 5's copy-paste-ready, common-cases-covered profile.

Workflow Clarity

The 7-step "Overall Workflow" is clearly sequenced with explicit validation checkpoints and feedback loops: inspect success/execution_outcome before reporting, correct the named failing field on invalid_input and retry, verify writes with the category's read-back operation, and never repeat a write whose outcome is unknown. Destructive operations (plugin.instance.purge, deletes, discard-corrupt) carry explicit rejection conditions and safety boundaries, satisfying the destructive/batch validation requirement that would otherwise cap this dimension.

Progressive Disclosure

The structure is well designed — the file self-declares as a routing guide ("Detailed operation contracts live in the linked category files under api/; load only the one category file needed"), with a 21-entry category index table mapping each namespace to its detail file and one-level-deep navigation. However, none of the referenced files (api/config.md through api/workflow.md, code-execution.md) exist in the provided bundle — no references/, scripts/, assets/, or api/ directories are present — so the entire detail layer the skill routes to is unverifiable and navigation breaks as shipped. This lands between anchor 4 (clear structure, minor gaps) and anchor 2 (references effectively unusable).

Specificity

The description names the domain and lists many capability areas ("media search, torrent search, downloads, subscriptions, library checks, sites, storage, workflows, schedulers, plugins, filter rules, and system settings") with broad coverage, but several entries are generic nouns ("sites", "storage", "system settings") rather than the concrete verb-phrases in the top anchor. It sits above anchor 3 (which expects only 1-2 concrete actions) but the noun-heavy tail keeps it below anchor 5.

Completeness

Both halves are present: the "what" is explicit ("authorizes the structured moviepilot_api gateway") and the "when" is an explicit trigger clause ("Use this skill for MoviePilot product operations such as..."). It does not reach anchor 5 because the trigger is one broad category ("MoviePilot product operations") plus a noun list, without the concrete user-moment trigger phrases ("when the user asks to...") of the top example; it is well above anchor 3 where "when" is only weakly implied.

Trigger Term Quality

Good natural keyword coverage — "media search", "torrent search", "downloads", "subscriptions", "plugins" are phrases a MoviePilot user would actually say. A few common variations and more colloquial forms (e.g., "add a subscription", "find a movie/TV show", "manage download tasks") are missing, so it falls just short of the comprehensive synonym-level anchor 5 and clearly above anchor 3's partial coverage.

Distinctiveness Conflict Risk

The niche is a single named product, and the description explicitly fences its scope ("authorizes the structured moviepilot_api gateway only; it does not authorize arbitrary HTTP, legacy Agent tools, MCP compatibility commands, authentication headers, or API tokens"), which minimizes overlap with generic HTTP/download skills and neighboring domain skills. It clearly matches anchor 5's clear-niche, minimal-conflict profile.
