Conciseness

The CLI command examples are lean, but padding is noticeable: a three-sentence platform pitch ("Big Cartel is an e-commerce platform... It provides simple tools for building a storefront..."), a content-free "Big Cartel Overview" bullet tree ("Products / Product / Orders / Order / Account"), and a broken aside ("Those will be used to adjust tooling to be used best with your harness"). Anchor 3 rather than 4 because multiple sections add no operational value.

Actionability

Nearly everything is copy-paste ready: "membrane connection ensure \"https://bigcartel.com\" --json", "membrane action run <actionId> --connectionId=... --input '{...}'", plus a 20-row actions table with keys and descriptions. Anchor 4 rather than 5 because examples stay placeholder-generic ({"key": "value"}) and the table lists action "Key" while run commands take an "actionId", leaving the mapping ambiguous.

Workflow Clarity

The connect-then-poll sequence has real checkpoints ("READY — skip to Step 2", "CLIENT_ACTION_REQUIRED — ... poll again", "CONFIGURATION_ERROR or SETUP_FAILED — check the error field"), but the referenced "Step 2" is never labeled anywhere in the document, and destructive actions (delete-category, delete-discount) are offered with no verification guidance. Per the rubric's cap for destructive/batch operations without validation, workflow clarity cannot exceed 3.

Progressive Disclosure

Section structure is decent, but ~20 rows of API-catalog content (the "Popular actions" table) are inlined where a reference file belongs, and the skill ships no bundle files at all (no references/, scripts/, or assets/). Anchor 3 ("content that should be separate is inline"), not 4, because there are no one-level-deep references to be "mostly clear" — everything lives in the single SKILL.md.

Specificity

Names the domain ("Big Cartel integration") but the actions — "Manage data, records, and automate workflows" — are generic boilerplate applicable to any integration; no concrete operations such as products, orders, or discounts are ever named. Closest to anchor 2 ("Names the domain but actions are minimal or generic"), not 3, because the description never states what is actually done with that data.

Completeness

Both parts are present: a what ("Manage data, records, and automate workflows") and an explicit when ("Use when the user wants to interact with Big Cartel data"), matching anchor 4. Not 5 because both the what and the when are generic and lack concrete trigger phrases; not 3 because the "Use when..." clause is explicit rather than missing or weakly implied.

Trigger Term Quality

The only substantive natural term is "Big Cartel" (used twice), mirroring anchor 3's "Works with PDF files" pattern. Not 4 — users would naturally say "products", "orders", "store", or "merch" and none appear; not 2 — "Big Cartel" is a specific domain keyword rather than generic filler like "files".

Distinctiveness Conflict Risk

"Big Cartel" names a clear niche with minimal conflict risk, but the surrounding boilerplate ("Manage data, records, and automate workflows") would read identically for any sibling app-integration skill, leaving the app name as the sole differentiator. Anchor 4 (mostly distinct, minor overlap with closely related skills) rather than 5 (distinct triggers beyond just the brand name).
