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

No annotations are provided, so the description carries the burden. It discloses that the tool dispatches through identical auth, billing, and validation as a direct call, and lists non-dispatchable tools. However, it does not mention error handling, rate limits, or response format, which would improve 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?

Description is two sentences plus an example, very concise. Front-loaded with the main purpose, no wasted words. Every sentence adds value.

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?

Given no output schema, the description does not explain the return value (presumably the result of the called tool). Also missing error handling notes. However, the tool is simple and the essential information is present.

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%, so description must compensate. It explains that 'name' should be a tool from search_tools, and 'arguments' are the wrapped tool's arguments. An example is provided. This adds meaning beyond the schema's type definitions, though the exact structure of arguments is left to the wrapped tool.

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?

Description clearly states the tool runs a tool found via search_tools by name and passes its arguments. It distinguishes itself by specifying which tools are dispatchable (safe/billable utility) and which are not (consequential), with examples. This provides a specific verb+resource and sibling differentiation.

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?

Explicitly tells when to use this tool (for utility tools from search_tools) and when not to (consequential tools like create_topup_link, etc., should be called directly). Also states that invocation is free (the wrapped tool bills itself). Provides clear usage context and alternatives.

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