Names two specific services (Google Doc, Gmail) and describes a concrete workflow (read content, use as email body), but only describes one narrow action rather than listing multiple capabilities.

Describes what the skill does but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric should cap completeness at 2, and the 'what' is also fairly narrow. The absence of any 'when' guidance caps this at 2, but the 'what' is also minimal, placing it closer to 1.

Includes natural keywords like 'Google Doc', 'Gmail', and 'email message', but misses common variations users might say such as 'send doc as email', 'email a document', 'Google Docs to email', or 'compose email from doc'.

The combination of Google Doc reading and Gmail sending is a very specific niche workflow that is unlikely to conflict with other skills. The cross-service integration (Docs → Gmail) creates a distinct trigger profile.

Very lean and efficient. The prerequisite note is necessary context, and the steps are minimal without explaining what Google Docs or Gmail are. Every token earns its place.

Provides concrete CLI commands with specific syntax, but step 2 ('Copy the text from the body content') is vague—it doesn't explain how to extract text from the structured document response (which returns JSON with nested structural elements, not plain text). The placeholder 'CONTENT_FROM_DOC' lacks guidance on how to actually extract and format the content.

Steps are sequenced clearly, but there's no validation—no check that the document was retrieved successfully, no handling of empty documents, and no verification that the email was sent. For an operation that sends email (a non-reversible action), a validation checkpoint before sending would be important.

For this simple, short skill (under 50 lines, single task), the structure is appropriate. It references prerequisite skills clearly and keeps the content concise without needing external files.
