delete_file

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

Annotations already flag destructiveHint=true. The description adds value by specifying that chunks and vectors are also deleted, giving a fuller scope of the operation's effects. It does not contradict 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 concise sentences: first clearly states the purpose, second provides a practical usage tip. No fluff, front-loaded, every sentence earns its place.

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 simple destructive tool with full schema coverage and an annotation, the description adequately covers the deletion scope and provides an update workflow hint. It could mention irreversibility or permissions, but these are implied by the destructive hint. Overall sufficient.

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?

The input schema already documents both parameters (containerId and fileId) with descriptions, achieving 100% coverage. The description does not add extra semantic detail beyond what the schema provides, so the baseline score of 3 is appropriate.

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?

The description clearly states 'Delete a file and all its chunks and vectors', which specifies the verb (delete) and resource (file and associated data). It also distinguishes from siblings like bulk_delete by implying single-file deletion via the fileId parameter, and provides additional context about updating.

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 includes explicit guidance for updating: 'To update a file, delete it first then re-upload with upload_file.' However, it does not explicitly warn against using this tool for bulk deletions or when to prefer bulk_delete, though the parameterization hints at single-file usage.

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