Remove File from Session

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

Annotations mark the tool as destructive (destructiveHint: true), but the description strengthens this by stating the file is permanently deleted from cloud storage and cannot be undone. It also documents error handling (404 for missing session/file), providing additional behavioral detail beyond the 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?

The description is well-structured with clear sections for purpose, consequence, arguments, return value, and errors. Each sentence provides necessary information without padding.

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 2-parameter tool, the description covers the operation's effect (permanent deletion), the exact return JSON, and error conditions. No output schema is present, but the description compensates by explicitly specifying the return value.

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?

Both parameters (session_id and file_id) have full schema descriptions, and the description's Args section essentially restates the schema. No additional syntax, precedence, or format details are provided, so the description adds no semantic value beyond the schema.

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 the action: remove a single PDF file from an upload session. The verb 'Remove' and resource 'PDF file from an upload session' are specific and distinct from sibling tools that upload, merge, or generate download links.

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 implies the tool is for deleting a file from a session but does not explicitly state when to choose it over alternatives or when not to use it. No exclusion or alternative tool is mentioned, leaving usage context implicit rather than explicit.

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