Quality

Content

61%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The skill delivers genuinely actionable CLI guidance with a solid polling/feedback model for connection states, but is undermined by an incoherent step structure (dangling 'Step 2', orphaned '1b', empty 'Popular actions') and padded introductory sections. Tightening the workflow numbering and trimming boilerplate would lift it substantially.

Suggestions

Fix the workflow numbering: define the steps explicitly (1. Install, 2. Authenticate, 3. Connect, 4. Discover actions, 5. Run) so references like 'skip to Step 2' resolve to real sections.

Populate 'Popular actions' with actual example action names (e.g. list/search conversations, send message, update user) or remove the empty section.

Trim the introductory prose (the 'what is CommBox' paragraph and the Overview bullet list with 'Use action names and parameters as needed') and standardize on one CLI invocation form (`membrane` vs `npx @membranehq/cli`).

DimensionReasoningScore

Conciseness

The body is mostly efficient commands and tables, but contains unnecessary prose ("CommBox is a customer communication platform. It's used by businesses to manage and respond to customer inquiries...") and a vacuous Overview section ending in "Use action names and parameters as needed". Not 4 because these padded sections and filler sentences could be trimmed without losing information.

3 / 5

Actionability

Concrete, copy-paste-ready commands cover install, login, headless auth, connection setup, polling, action discovery, action execution, and proxy requests, plus a flags table. Not 5 because invocation is inconsistent (`membrane` vs `npx @membranehq/cli`), the 'Popular actions' section contains no actual actions, and the referenced 'Step 2' does not exist.

4 / 5

Workflow Clarity

The install → login → connection → poll → discover → run sequence exists with state-based checkpoints (READY / CLIENT_ACTION_REQUIRED / CONFIGURATION_ERROR with re-poll instructions), but the flow references a 'Step 2' that is never defined, has an orphaned '1b' heading, and the 'Popular actions' section is empty. These gaps in an otherwise present sequence match 'steps listed but validation gaps; sequence present but checkpoints missing or implicit' more than the cleaner anchor 4.

3 / 5

Progressive Disclosure

The single-file skill (no references/, scripts/, or assets/ exist) is organized into clear sections (Install, Authentication, Connecting, Searching, Running, Proxy, Best practices) with no nested or dangling file references. Not 5 because at ~140 lines, content like the proxy flag table and clientAction schema could be split out, and the section ordering is slightly jumbled (Running actions appears under Popular actions).

Description

50%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description correctly anchors both 'what' and 'when' to the CommBox brand, giving it low conflict risk, but its capability language is generic CRM boilerplate with no natural trigger vocabulary. Users asking about conversations, chats, tickets, or customer messages would not naturally match this description.

Suggestions

Replace the generic 'Manage data, records, and automate workflows' with CommBox-specific capabilities, e.g. 'Search and update customer conversations, send messages across channels, and manage users'.

Expand the 'Use when' clause with natural trigger phrases users would actually say: 'Use when the user mentions CommBox, customer conversations, shared inbox, chats, or customer messages'.

Name the core objects (conversations, messages, users) that the skill can act on so the description doubles as a capability summary.

DimensionReasoningScore

Specificity

"Manage data, records, and automate workflows" are generic actions applicable to nearly any business app; only the domain name (CommBox) is concrete. This matches the anchor 'Names the domain but actions are minimal or generic' — not 3, since no action names a CommBox capability like conversations, messages, or channels; not 1, since the domain is named at all.

2 / 5

Completeness

Both parts are present: a 'what' ("CommBox integration. Manage data, records, and automate workflows") and an explicit 'when' ("Use when the user wants to interact with CommBox data"). Not 5 because the 'when' is tautological (restates the brand rather than giving concrete trigger phrases) and the 'what' is vague.

4 / 5

Trigger Term Quality

The only real keyword is the brand "CommBox" plus generic "data", "records", "workflows"; no natural user phrases like conversations, inbox, chats, tickets, or customer messages. Not 3 because the description misses essentially all common variations and synonyms a user would naturally say.

2 / 5

Distinctiveness Conflict Risk

The brand anchor "CommBox" gives a clear, distinct niche, and the description is unlikely to trigger for unrelated skills. Not 5 because the generic middle sentence ("Manage data, records, and automate workflows") overlaps with any data/automation skill if the brand token is missed.
