Discovery
32%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 clear domain (Gmail) and basic functionality but suffers from missing explicit trigger guidance and limited keyword coverage. It would benefit significantly from a 'Use when...' clause and additional natural terms users might use when needing this skill.
Suggestions
Add a 'Use when...' clause with trigger terms like 'search Gmail', 'find emails', 'export messages', 'email search'
Include common variations users might say: 'email', 'inbox', 'search emails', 'download emails'
Specify what 'export for review' means - formats, destinations, or review capabilities
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Gmail) and two actions (find messages, export for review), but lacks comprehensive detail about what 'export' means or what formats/capabilities are available. | 2 / 3 |
Completeness | Describes what the skill does but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes 'Gmail messages' and 'query' which are relevant, but misses common variations users might say like 'email', 'search emails', 'download messages', or 'inbox'. | 2 / 3 |
Distinctiveness Conflict Risk | Gmail-specific which helps distinguish from generic document skills, but could overlap with other email-related skills; lacks explicit triggers to clarify its niche. | 2 / 3 |
Total | 7 / 12 Passed |
Implementation
87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted, concise skill that provides immediately actionable CLI commands for Gmail search and export. Its main weakness is the lack of validation steps - there's no guidance on checking if the search returned results before proceeding to get individual messages, or verifying the export file was created successfully.
Suggestions
Add a validation step after the search to check if results were returned (e.g., 'If no messages found, adjust query parameters')
Include error handling guidance for common issues like invalid message IDs or authentication failures
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations, assumes Claude knows what Gmail and JSON are. Every line serves a purpose. | 3 / 3 |
Actionability | Provides fully executable CLI commands with realistic example parameters. Copy-paste ready with clear placeholders (MSG_ID) where user input is needed. | 3 / 3 |
Workflow Clarity | Steps are clearly sequenced but lacks validation checkpoints. No guidance on handling errors, empty results, or verifying the export succeeded before proceeding. | 2 / 3 |
Progressive Disclosure | For a simple, single-purpose skill under 50 lines, the structure is appropriate. Clear prerequisite callout, concise steps, no need for external references. | 3 / 3 |
Total | 11 / 12 Passed |
Validation
