delete_file

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

With no annotations, the description must disclose behavioral traits, but it only says 'Delete a file.' It fails to mention whether the deletion is permanent, whether fileId refers to an internal identifier, what happens to associated data, or whether special permissions are needed. This is a serious gap for a destructive operation.

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 extremely concise with no filler words, and it front-loads the core action. However, it is so terse that it provides no structural or contextual detail, making it less 'appropriately sized' for a destructive tool.

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 operation with no annotations and no output schema, this description is completely inadequate. It omits any mention of irreversibility, side effects, response behavior, preconditions, or error handling, leaving the agent without necessary context to invoke it safely.

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 has 100% coverage for the single parameter fileId, so the schema already documents the parameter. The description adds no extra meaning beyond what the schema provides, but the high schema coverage establishes the baseline of 3.

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 'Delete a file' is a direct restatement of the tool name 'delete_file' and adds no new information. It does not specify the file scope, system context, or distinguish this from related file operations like delete_file_snapshot.

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 guidance on when to use this tool versus alternatives such as delete_team or delete_comment, nor any mention of important context like permanent vs. reversible deletion or required permissions. The description simply states the action without usage conditions.

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