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

With empty annotations, the description carries the full burden of behavioral disclosure. It mentions a confirmation step and the mutation of a name, but does not disclose whether the operation is reversible, whether the bridge must exist, or any permission or side-effect details. The duplicated sentence consumes space that could have been used for additional behavioral context.

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 short but contains a redundant repetition of the main action: 'Changes the Bridge's descriptive name.' appears twice, once before and once after the confirmation note. This duplication is unnecessary and slightly harms structure, though the @param list is clearly organized.

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?

All parameters are explained and the return type is noted, with an output schema present to cover return details. However, the confirmation instruction is ambiguous (does the API require confirmation, or should the agent ask the user?), and there is no mention of prerequisites or error conditions. For a mutation tool with no annotations, this leaves notable gaps.

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 @param lines add meaningful context beyond the schema, explaining the source or purpose of each parameter (e.g., token from /access/login, external_account_id from /bridge/list, alias as the new name). Since the schema has 0% description coverage, this fully compensates and provides clear guidance for all five parameters.

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 tool changes a Bridge's descriptive name, using a specific verb and resource. It distinguishes from siblings like bridge_delete or bridge_list by focusing on the renaming action, and the duplicate sentence does not obscure this.

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 instruction 'Confirm (yes/no) before executing' provides some usage guidance, but there is no explicit advice on when to choose this tool over alternatives or when not to use it. Sibling tools such as bridge_delete and bridge_list are not referenced, leaving the usage context implicit rather than explicit.

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