Names the domain (Google Drive) and one action (upload a file with automatic metadata), but does not list multiple concrete actions or elaborate on what 'automatic metadata' entails.

Describes what it does (upload a file with automatic metadata) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, missing 'Use when' caps completeness at 2, and the 'what' is also thin, warranting a 1.

Includes 'Google Drive' and 'upload a file' which are natural terms users might say, but misses common variations like 'upload to Drive', 'share file', 'Google Docs', or file type mentions.

Specifying 'Google Drive' and 'upload' provides some distinctiveness, but 'upload a file' is generic enough to potentially overlap with other cloud storage or file management skills.

Every token earns its place. No unnecessary explanations of what Google Drive is or how file uploads work. The tips section is minimal and adds genuinely useful information about MIME type detection and filename inference.

Provides concrete, copy-paste ready CLI commands with clear flag descriptions and multiple usage examples covering common scenarios. The flag table is precise with required/default columns.

This is a simple single-action skill (upload a file), so no multi-step workflow is needed. The caution callout about confirming with the user before executing serves as an appropriate validation checkpoint for a write operation.

Clean overview with well-signaled one-level-deep references to shared auth/flags skill and parent drive skill. The prerequisite callout at the top clearly directs to shared configuration without inlining it.
