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

With no annotations, the description carries the burden of behavioral disclosure. It mentions the HTTP verb POST, but does not mention any side effects, required permissions, validation rules, idempotency, or exceptions. The tool is a create operation, so the agent might benefit from knowing whether it can be repeated or if there are constraints, but nothing is disclosed.

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 and front-loads the purpose. However, it uses a repetitive pattern (repeating 'provide' for each parameter class) that could be condensed, but overall it is efficient for the length.

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?

Despite the presence of an output schema, the description lacks essential details for an agent to call the tool successfully. It doesn't explain what specific fields are required in body, what the path parameters are, or how to construct the request. The tool is part of a complex API, but the description is generic and insufficient.

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 coverage is 0%, so the description must explain the parameters. It only says to put route IDs in path_params, filters/pagination in query, headers in headers, and payload in body, but gives no details on actual structure or required fields. This is a generic restatement of the parameter names, not actionable semantics.

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 states that the tool creates an agent credential mapping, which is a specific verb and resource. It also gives the endpoint path, making the function clear. However, it does not differentiate from the sibling tools like patch or delete for the same resource, but the create intent is clear.

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 says to provide route IDs, filters, pagination, headers, and payload, but does not specify when to use this tool versus the get/patch/delete siblings. No context about prerequisites or typical use cases is given, leaving the agent to infer when creation is appropriate.

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