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 the tool and lists supported Google services but lacks concrete action verbs and completely omits trigger guidance. It tells Claude this skill exists for Google Workspace but doesn't help Claude understand when to choose it over other document, email, or spreadsheet-related skills.
Suggestions
Add a 'Use when...' clause specifying triggers like 'when user mentions Gmail, Google Calendar, Google Drive, or asks to send emails, schedule meetings, or access Google documents'
Include specific actions for each service: 'Send and read Gmail messages, create Calendar events, upload/download Drive files, manage Contacts, edit Sheets and Docs'
Add natural language variations users might say: 'google email', 'gcal', 'google spreadsheet', 'schedule a meeting', 'check my inbox'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Google Workspace CLI) and lists specific services (Gmail, Calendar, Drive, Contacts, Sheets, Docs), but doesn't describe concrete actions like 'send emails', 'create events', or 'upload files'. | 2 / 3 |
Completeness | Only answers 'what' at a high level (it's a CLI for Google services) 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 good product names (Gmail, Calendar, Drive, Sheets, Docs) that users would naturally mention, but missing common variations like 'email', 'spreadsheet', 'google docs', 'schedule meeting', or action-oriented terms users would say. | 2 / 3 |
Distinctiveness Conflict Risk | The Google Workspace focus provides some distinctiveness, but 'Sheets' could conflict with Excel skills, 'Docs' with document editing skills, and 'Drive' with general file management skills without clearer boundaries. | 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 CLI reference skill that efficiently documents the gog tool with concrete, executable examples. The command reference format is appropriate and token-efficient. The main weakness is the lack of explicit validation workflows for destructive operations like sending emails or creating events, though the skill does mention confirming before these actions.
Suggestions
Add an explicit verification workflow for email sending (e.g., 'Create draft first with `gog gmail drafts create`, verify content, then send with `gog gmail drafts send`')
Include a brief troubleshooting note for common auth failures to help with error recovery
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, presenting commands in a reference-style format without explaining what Gmail, Calendar, or Drive are. Every line provides actionable command syntax or essential notes. | 3 / 3 |
Actionability | All commands are copy-paste ready with concrete examples including flags, arguments, and realistic placeholders. The heredoc and HTML examples are fully executable. | 3 / 3 |
Workflow Clarity | Setup steps are clearly sequenced, but the skill lacks validation checkpoints for potentially problematic operations. The 'Confirm before sending mail or creating events' note is mentioned but not integrated into a workflow with explicit verification steps. | 2 / 3 |
Progressive Disclosure | For a CLI reference skill of this scope, the content is well-organized into logical sections (Setup, Common commands, Calendar Colors, Email Formatting, Notes) without needing external file references. Navigation is clear and content is appropriately structured. | 3 / 3 |
Total | 11 / 12 Passed |
Validation
72%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
