delete_file

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

With no annotations, the description carries full behavioral disclosure burden. It only says 'Delete a file' without stating consequences (permanent deletion, no undo), required permissions, or error behavior (e.g., if file doesn't exist).

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, using only three lines with no filler. The action ('Delete a file') is front-loaded, and parameter/return info is clearly structured.

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?

Given the tool's simplicity (1 param, no output schema), the description covers the core action but omits details like whether deletion is permanent and the exact structure of the result dictionary. It is minimally adequate but not thorough.

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 description adds context to the path parameter ('relative to data directory') beyond the schema's type-only specification. However, it does not fully cover all aspects (e.g., allowed characters, max length), and schema coverage is 0%, so the description provides moderate compensation.

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 explicitly states 'Delete a file', which is a specific verb and resource. It clearly distinguishes itself from sibling tools like create_file, read_file, and update_file.

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?

No guidance on when to use this tool over alternatives. For example, it does not mention prerequisites (e.g., file must exist) or context where this is appropriate vs. using execute_command for deletion.

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