delete_files

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

The description states 'Deletes' which indicates a destructive action, but with no annotations, it does not disclose whether deletion is permanent, if any permissions are required, or what happens to associated data. It lacks behavioral context beyond the basic action.

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, clear sentence with no unnecessary words. It front-loads the action and resource.

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?

The description is adequate for a simple delete operation, but it does not mention return values or side effects, relying solely on the name and one-line description. Given the absence of an output schema and annotations, the agent may not know what to expect after invoking the tool.

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 already documents the file_ids parameter at 100% coverage, and the description merely restates 'by their IDs' without adding additional format, constraints, or usage details.

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'), the resource ('files'), and the method ('by their IDs'). It distinguishes from sibling tools like delete_folder or delete_message by specifying files.

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 explicit guidance on when to use this tool versus alternatives is provided, but the intent is clear from the description and tool name. It implies that this is the tool for deleting files, but does not mention alternatives or exclusions.

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