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 clear, specific task but suffers from missing explicit trigger guidance ('Use when...') which is critical for skill selection. While the action is well-defined and distinctive, the lack of natural keyword variations and missing when-clause significantly limit its effectiveness for Claude's skill selection process.
Suggestions
Add a 'Use when...' clause with trigger terms like 'new month', 'copy template', 'monthly spreadsheet', 'duplicate tab'
Include common keyword variations users might say: 'spreadsheet', 'copy', 'clone', 'monthly tracking sheet'
Consider expanding to list related actions if applicable (e.g., 'rename tab', 'update date references')
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Google Sheets) and a specific action (duplicate template tab for new month), but only describes one action rather than multiple concrete capabilities. | 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 relevant terms like 'Google Sheets', 'template', 'tab', and 'month', but missing common variations users might say like 'spreadsheet', 'copy', 'clone', or 'monthly tracking'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche - duplicating template tabs for monthly tracking in Google Sheets is distinct and unlikely to conflict with other skills due to its narrow, well-defined scope. | 3 / 3 |
Total | 8 / 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 actionable CLI commands for duplicating a Google Sheets template. The main weakness is the lack of validation steps - there's no guidance on verifying the copy operation succeeded or how to find the new sheetId after copying before renaming.
Suggestions
Add a verification step after the copy operation to confirm success and retrieve the new sheetId from the response
Include a note about how to find the correct sheetId for the template tab (step 1's response contains this)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, providing only the essential commands without explaining what Google Sheets is or how APIs work. Every line serves a purpose. | 3 / 3 |
Actionability | Provides fully executable CLI commands with concrete JSON parameters. The commands are copy-paste ready with clear placeholders (SHEET_ID, sheetId: 123) that indicate what needs customization. | 3 / 3 |
Workflow Clarity | Steps are clearly sequenced (get -> copy -> rename), but lacks validation checkpoints. No guidance on verifying the copy succeeded or handling errors if the template sheet doesn't exist or the sheetId is wrong. | 2 / 3 |
Progressive Disclosure | For a simple 3-step skill under 50 lines, the structure is appropriate. The prerequisite skill reference is clearly signaled, and the content is well-organized without needing external files. | 3 / 3 |
