75%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 adequately identifies the 15Five integration and provides explicit 'Use when' guidance, which is good for skill selection. However, it lacks specificity in the actions it can perform (only 'Manage' is mentioned) and misses natural language variations users might use when referring to HR/performance management concepts.
Suggestions
Expand 'Manage' into specific concrete actions like 'create, update, list, and delete Persons and Organizations'
Add natural trigger terms users might say such as 'employees', 'team members', 'HR data', 'performance reviews', or '1-on-1s'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (15Five) and mentions 'Manage Persons, Organizations' which are some actions, but lacks comprehensive concrete actions like 'create', 'update', 'delete', 'list', or 'sync'. | 2 / 3 |
Completeness | Explicitly answers both what ('Manage Persons, Organizations') and when ('Use when the user wants to interact with 15Five data'), meeting the requirement for explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes '15Five' as a key trigger term and 'Persons, Organizations' as entity types, but misses common variations users might say like 'employees', 'team members', 'companies', 'HR data', or 'performance management'. | 2 / 3 |
Distinctiveness Conflict Risk | '15Five' is a specific product name that creates a clear niche with distinct triggers, making it unlikely to conflict with other integration skills. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides solid actionable guidance with executable CLI commands and a useful actions reference table. However, it includes some unnecessary introductory content, lacks validation/error handling workflows, and could benefit from better content organization with external references for the actions catalog.
Suggestions
Remove the introductory paragraph explaining what 15Five is - Claude already knows this and it wastes tokens
Add validation steps after key operations (e.g., 'Verify connection succeeded by running membrane connection list')
Include error handling guidance - what to do when commands fail or authentication expires
Consider moving the Popular Actions table to a separate ACTIONS.md reference file to keep the main skill leaner
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill includes some unnecessary explanation (e.g., 'It's used by HR departments, managers, and employees...') and the overview section listing features without actionable context. The Membrane setup instructions are reasonably efficient but could be tighter. | 2 / 3 |
Actionability | Provides fully executable CLI commands throughout with clear syntax examples. The action table, proxy request options, and parameter passing examples are copy-paste ready and specific. | 3 / 3 |
Workflow Clarity | Steps are listed for setup and connection but lack explicit validation checkpoints. No feedback loops for error recovery (e.g., what to do if connection fails, how to verify actions succeeded). | 2 / 3 |
Progressive Disclosure | Content is reasonably organized with clear sections, but everything is inline in one file. The popular actions table could be a separate reference file, and there are no links to additional documentation for advanced use cases. | 2 / 3 |
