Evals

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 is functional but minimal, clearly identifying the Google Drive domain and two core actions. However, it lacks explicit trigger guidance ('Use when...') which is critical for skill selection, and could benefit from more natural keyword variations to improve discoverability.

Suggestions

Add a 'Use when...' clause with explicit triggers like 'Use when the user asks to access Google Drive, retrieve files from Drive, or mentions gdrive folders'

Include common keyword variations users might say: 'gdrive', 'Drive files', 'shared Drive folder', 'Google docs folder'

Consider expanding capabilities mentioned if applicable (e.g., handling shared drives, specific file types, recursive folder access)

Dimension	Reasoning	Score
Specificity	Names the domain (Google Drive) and two specific actions (list and download), but is not comprehensive - doesn't mention other potential capabilities like uploading, searching, or handling different file types.	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 'Google Drive' and 'folder' which are natural terms, but missing common variations like 'gdrive', 'Drive files', 'shared folder', or file-specific terms users might mention.	2 / 3
Distinctiveness Conflict Risk	'Google Drive' provides some distinctiveness from generic file skills, but could overlap with other cloud storage skills or general file management skills without clearer trigger 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, concise skill that provides actionable commands for bulk downloading from Google Drive. Its main weakness is the lack of validation steps for batch operations - there's no guidance on verifying downloads succeeded or handling failures when processing multiple files.

Suggestions

Add a validation step to verify downloaded files (e.g., check file exists and has non-zero size after each download)

Include error handling guidance for when file downloads fail or when encountering permission issues

Dimension	Reasoning	Score
Conciseness	Extremely lean and efficient. No unnecessary explanations, assumes Claude knows what Google Drive is and how CLI tools work. Every line serves a purpose.	3 / 3
Actionability	Provides concrete, copy-paste ready commands with proper syntax for listing, downloading, and exporting files. Includes specific parameter formats and output flags.	3 / 3
Workflow Clarity	Steps are clearly numbered and sequenced, but lacks validation checkpoints. For batch operations downloading multiple files, there's no error handling, verification that downloads succeeded, or feedback loop for failed downloads.	2 / 3
Progressive Disclosure	Appropriate for a simple, single-purpose skill under 50 lines. Clear prerequisite reference to the gws-drive skill, well-organized with a single steps section. No need for external references given the scope.	3 / 3
