Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond destructiveHint=true by explaining the mechanism: Google Drive for Desktop syncs the deletion to the cloud, the item lands in Drive's trash (so it is recoverable), and pointer files delete the underlying real document rather than the shortcut. It also discloses a safety guard (non-empty folders are never deleted) and notes that the confirm parameter is ignored — genuinely useful behavior an agent could not infer from annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two dense sentences, with the destructive scope and cloud-sync consequence front-loaded, followed by the pointer caveat and the folder guard. No filler, and each clause carries a distinct operational fact.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive file-removal tool this covers what is needed: what gets deleted, where it goes (trash), how pointers behave, and what is refused. An output schema exists, so return values needn't be described.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the path format and the 'ignored' status of confirm are already documented in structured fields. The description adds no parameter-level detail beyond that, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource with explicit scope: deletes a file or empty folder within the synced Google Drive folder. It also distinguishes the special case of .gdoc/.gsheet/.gslides pointers, which no sibling tool covers, so an agent can separate it from onedrive_delete_file and recipe_delete.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description establishes preconditions implicitly ('Never deletes a folder that still has contents', the path must be under a Drive mount), but it never states when to pick this over siblings such as onedrive_delete_file, nor does it route the agent to gdrive_file_info or gdrive_list_files to confirm a path before deleting. Usage is inferable but not spelled out.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
