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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Deletes' correctly implies a destructive mutation, it fails to address critical aspects like whether deletion is permanent or reversible, what happens if the file doesn't exist, permission requirements, or any rate limits. This leaves significant behavioral gaps 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 a single, focused sentence that efficiently conveys the core functionality without any wasted words. It's appropriately sized for a simple tool with one parameter and gets straight to the point.

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 file operation with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what happens on success versus failure, whether there's confirmation or error handling, or what (if anything) the tool returns. Given the complexity of file deletion and lack of structured safety information, more behavioral context is needed.

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 schema description coverage is 100%, with the single parameter 'filepath' clearly documented in the schema as 'Path to the file to delete'. The description adds no additional parameter semantics beyond what's already in the structured schema, meeting the baseline for high schema coverage.

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 ('Deletes') and resource ('a file at the specified path'), making the tool's purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'delete_directory' or 'move_file' which also involve file system modifications, missing an opportunity for clearer sibling distinction.

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 provides no guidance on when to use this tool versus alternatives like 'move_file' for relocation or 'delete_directory' for folder removal. It also lacks information about prerequisites such as file existence checks or permission requirements, leaving the agent without contextual usage cues.

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