The description names a specific domain (Google Workflow) and a concrete action (announce a Drive file in a Chat space), but it only describes a single action rather than listing multiple specific capabilities.

The description answers 'what' (announce a Drive file in a Chat space) but completely lacks a 'Use when...' clause or any explicit trigger guidance, which per the rubric should cap completeness at 2, and since the 'when' is entirely missing, it scores a 1.

Includes relevant keywords like 'Drive file', 'Chat space', and 'announce', which are natural terms users might say. However, it misses common variations like 'Google Drive', 'Google Chat', 'share file', 'post link', 'notify', or 'send to channel'.

The description is quite specific to a narrow workflow involving Google Drive and Google Chat, making it clearly distinguishable from other skills and unlikely to conflict with unrelated skills.

The content is lean and efficient. Every section serves a purpose — flags table, examples, tips — with no unnecessary explanation of what Drive or Chat spaces are. No wasted tokens.

Provides concrete CLI commands and a clear flags table, but the examples use placeholder values (FILE_ID, spaces/ABC123) without showing expected output. There's no indication of what the actual workflow does under the hood (API calls, message format) or what success/failure looks like.

The tips mention using `gws drive +upload` first, hinting at a multi-step workflow, but there's no explicit sequenced workflow with validation. Since this is a write command that sends a Chat message, there's no verification step (e.g., confirming the message was sent, checking for errors). Missing feedback loops for a write operation caps this at 2.

Clear, well-organized structure with appropriate references to gws-shared and gws-workflow skills. The prerequisite callout is well-signaled, and the See Also section provides one-level-deep navigation to related skills.
