delete_file

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

The annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the agent already knows this is a destructive, irreversible operation. The description reinforces permanence ('permanently removes') and clarifies that only the provider-side reference is deleted, which adds nuance but little beyond what the annotations supply.

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 short sentences, the action and identifier front-loaded, with the destructive consequence stated immediately after. No filler or redundancy.

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?

Return values need not be explained since an output schema exists, and annotations cover the safety profile, so the description is nearly sufficient. It could still note where a valid file_id is obtained or what happens when the id is unknown, but for a one-parameter mutation it is largely complete.

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 description coverage is 0% for the single required parameter, so the description must carry the load; it identifies file_id as referencing an uploaded DeepSeek image, which gives useful meaning. However, it omits the expected 'file-api-' format/constraint and does not say where the id comes from (e.g., upload_file or list_files).

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 ('Delete') and resource ('one uploaded DeepSeek image' identified by file_id'), which clearly separates it from siblings like upload_file, list_files, and retrieve_file. It stops short of explicitly naming those alternatives, but the action and target are unambiguous.

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?

There is no when-to-use or when-not-to-use guidance, no prerequisites (e.g., ownership of the file), and no mention of alternatives such as re-uploading or listing files first. Usage is only implied by the verb 'Delete'.

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