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

With no annotations, the description carries the behavioral burden. It does disclose that this is a write operation and that confirmation is required, but it does not explain the confirmation workflow, persistence of changes, or side effects. This is partial transparency, not full.

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 compact sentence with no filler. Every phrase adds value: it names the target, categorizes the operation, and flags a prerequisite.

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 confirmation-gated write operation with no annotations and no output schema, the description is too sparse. An agent cannot determine how to obtain the confirmation token, when to provide user_code, or what a successful call returns.

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?

Schema description coverage is 0%, and the description only indirectly explains the 'name' parameter. The parameters user_code, confirm_token, and confirmation_id are not described at all; 'requires confirmation' is too vague to clarify their roles.

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 uses a specific verb and resource: 'Set router name'. It also flags the operation type as a write, clearly distinguishing it from the many read-only show_*/status siblings.

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 implies the tool should be used when the router's name needs to be changed, and it signals a confirmation prerequisite. However, it provides no explicit guidance about alternatives or the exact circumstances under which to invoke it.

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