Discovery
40%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 identifies a specific product (Acelle Mail) but is otherwise very thin on detail. It lacks concrete actions beyond 'Manage Users', provides no meaningful trigger terms beyond the product name, and the 'Use when' clause is too vague to be useful for skill selection among many options.
Suggestions
List specific concrete actions such as 'create users, update subscriber lists, manage campaigns, view sending statistics' instead of just 'Manage Users'.
Expand the 'Use when' clause with natural trigger terms like 'email marketing', 'mailing lists', 'subscribers', 'email campaigns', 'Acelle API'.
Add context about what Acelle Mail is (e.g., 'email marketing platform') so Claude can match it even when users describe the task without naming the product.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description says 'Manage Users' which is a single vague action. It doesn't list concrete actions like create users, delete users, update permissions, list subscribers, etc. 'Interact with Acelle Mail data' is abstract. | 1 / 3 |
Completeness | It has a weak 'what' (Manage Users) and a 'when' clause ('Use when the user wants to interact with Acelle Mail data'), but the 'when' is extremely vague and essentially restates the 'what' without providing explicit triggers or scenarios. | 2 / 3 |
Trigger Term Quality | 'Acelle Mail' is a specific product name that users would naturally mention, and 'Users' is a relevant keyword. However, it's missing common variations and related terms like 'email marketing', 'subscribers', 'mailing lists', 'campaigns', or specific API operations. | 2 / 3 |
Distinctiveness Conflict Risk | 'Acelle Mail' is a specific product which helps with distinctiveness, but 'Manage Users' and 'interact with data' are generic enough that they could overlap with other user management or email platform skills. | 2 / 3 |

Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable skill with excellent workflow clarity for the connection setup process and fully executable CLI commands throughout. Its main weaknesses are unnecessary introductory context about Acelle Mail that Claude doesn't need, and a somewhat monolithic structure that could benefit from splitting the actions reference table and connection state documentation into separate files.
Suggestions
Remove the opening paragraph explaining what Acelle Mail is — Claude already knows this and it wastes tokens.
Consider extracting the popular actions table into a separate ACTIONS.md reference file to reduce the main skill's length and improve progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The opening paragraph explaining what Acelle Mail is (similar to MailChimp, used by businesses, etc.) is unnecessary context Claude doesn't need. The overview hierarchy and some sections are reasonably lean, but there's padding throughout, such as explaining what Membrane handles and general descriptions Claude could infer. | 2 / 3 |
Actionability | The skill provides concrete, copy-paste-ready CLI commands for every step: installation, authentication, connection setup, action discovery, action execution, and proxy requests. The popular actions table with keys and descriptions, plus the flag reference table for proxy requests, give Claude everything needed to execute. | 3 / 3 |
Workflow Clarity | The connection workflow is clearly sequenced with explicit state-based branching (READY, CLIENT_ACTION_REQUIRED, CONFIGURATION_ERROR), polling instructions with --wait flag, and clear next steps for each state. The headless authentication flow includes a feedback loop (user completes login → finish with code). The overall flow from install → auth → connect → discover → run is well-structured. | 3 / 3 |
Progressive Disclosure | The content is a single monolithic file with no references to supporting files, which is acceptable given no bundle files exist. However, the popular actions table (20 rows) and the detailed connection state machine could be split into separate reference files. The structure uses headers well but the file is long enough that splitting would improve navigation. | 2 / 3 |
