B3/5.0
Behavior3/5

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

The annotations already communicate destructiveHint=true, readOnlyHint=false, and idempotentHint=true, so the safety profile is covered. The description adds the exact HTTP DELETE endpoint but does not disclose additional behavioral context such as permanence, side effects, or authorization requirements. This is acceptable but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is brief and organized into purpose, endpoint, and arguments. It avoids unnecessary prose, though 'Delete Command.' is somewhat redundant with the tool name and endpoint.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter delete endpoint, the description is minimally viable: the path and parameter are present, and the output schema plus annotations cover response and safety. However, it lacks any usage context or indication of what happens when a command is deleted, so it is not complete on its own.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema coverage, the description must carry parameter meaning. It only identifies 'id' as a path parameter, which adds location but not what the ID represents or its constraints. The endpoint and tool name imply it is the command ID, but the description itself does not state this.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the verb and resource directly ('Delete Command') and the HTTP endpoint DELETE /api/v3/command/{id} makes the operation unambiguous. It is distinguishable from sibling tools like get_command_by_id, list_command, and create_command, though it does not provide extra clarification about the command lifecycle.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance about when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or situations where a different tool should be used. The agent must infer from the name that this is for deleting a command by ID.

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