Conciseness

The body is mostly command-driven and efficient, but it opens by explaining what Mercado Libre is ("the largest online marketplace in Latin America. It's similar to eBay or Amazon...") and narrates Membrane's behavior conceptually — concepts Claude already knows. Matches 'Mostly efficient but includes some unnecessary explanation or could be tightened'; not a 4 because the intro paragraph and a few explanatory sentences are clearly trimmable padding.

Actionability

It provides copy-paste-ready commands for every common case — install (`npm install -g @membranehq/cli@latest`), login, `connection ensure`, action list/run with `--input` JSON, and a full proxy flag table. Matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

The connect flow has explicit validation checkpoints and a feedback loop (poll until READY, re-poll after CLIENT_ACTION_REQUIRED), which is strong, but the step numbering is broken: the text references 'Step 2' and a '#### 1b' header with no 1a or Step 2 header defined. Matches 'Clear sequence with most checkpoints present; minor validation gaps'; not a 5 because the inconsistent numbering leaves the overall sequence slightly ambiguous.

Progressive Disclosure

No bundle files exist, and the self-contained CLI usage is appropriately inline and organized into clear sections (Overview, Install, Authentication, Connecting, Searching, Popular actions, Best practices). Matches 'Good structure; most content appropriately placed; minor organization gaps'; not a 5 because 'Popular actions' partly duplicates the 'Searching for actions' section and the structure could be tightened.

Specificity

It names the domain ("Mercado Libre integration") but the only action verb is "Manage Recordses" — a single minimal, generic action with no enumerated operations (the CRUD list lives in the body, not the description). This matches the anchor 'Names the domain but actions are minimal or generic', and is not a 3 because it does not list 1-2 concrete actions.

Completeness

It states a what ("Mercado Libre integration. Manage Recordses.") and an explicit when ("Use when the user wants to interact with Mercado Libre data"), and the 'Use when...' clause avoids the 3-cap. It fits 'Has both what and when; when could be more explicit or specific'; not a 5 because the what is vague ('Manage Recordses') and the when lacks concrete trigger phrases.

Trigger Term Quality

"Mercado Libre" is a strong distinctive keyword and "Use when the user wants to interact with Mercado Libre data" supplies a natural trigger, but coverage stops at one term with no synonyms or variations (no ML, marketplace, listings, orders). Matches 'Some relevant keywords but missing common variations or synonyms'; not a 4 because keyword breadth is thin.

Distinctiveness Conflict Risk

"Mercado Libre" is a single named external platform with distinct triggers, so conflict risk with other skills is minimal — matching 'Clear niche with distinct triggers; minimal conflict risk'.
