delete-file-by-id

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

Annotations are none, so the description carries the full behavioral burden. For a destructive operation, the description does not disclose whether deletion is permanent, whether special permissions are needed, what happens if the file is not found, or any side effects. It merely restates the tool name without adding transparency.

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 wastes no words. It earns its place by succinctly stating the tool's core function, achieving high conciseness.

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?

With no annotations, no output schema, and no parameters documented, the description falls short of providing sufficient context for a destructive tool. It omits critical behavioral details like permanence, error handling, and impact on related resources. The tool is simple, but the lack of any supplementary context makes it incomplete.

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 0 parameters, yet the description mentions deletion 'by its ID', implying the existence of an ID that is not in the schema. While the baseline for 0 parameters is 4, the description introduces a potential mismatch and does not explain how the ID is passed. The description adds minimal meaning beyond the tool name.

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 by its ID' clearly states the action (delete), the resource (file), and the identifier (ID). It distinguishes this tool from siblings like add-file, update-file-by-id, and get-file-by-id, making its purpose 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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of irreversibility, prerequisites, or exclusions (e.g., 'use move-file-to-location instead of delete if you want to keep the file'). The implied usage is apparent from the name, but the description offers no additional context.

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