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

No annotations are provided, so the description must fully disclose side effects and safety. It says the code is 'working' and to copy it as is, but it does not explicitly state that the tool itself only returns code and does not perform any charging or state modification. It also omits whether invoking the tool triggers external calls or requires permissions.

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 two sentences but somewhat run-on, mixing the purpose, the test URL, and copy instructions. It front-loads the main intent but could be more structured and concise, with each clause serving a clear role.

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?

The tool returns code and a URL, but the description does not specify the output format (e.g., JSON structure), whether authentication is required, or what the 'wallet' refers to. This leaves gaps that an agent would need to resolve to correctly handle the response.

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 input schema provides a description for the 'role' parameter but not for 'language' or 'framework' beyond enums. The description only references 'language and framework you name', which adds no new meaning. With schema coverage at 33%, the description should compensate but does not.

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 indicates the tool provides working code for charging a route and a test URL, with a specific subject and purpose. It distinguishes itself from sibling tools (status, pricing, resource lookup) by focusing on integration code, though it does not explicitly name them or use a crisp action verb like 'generate'.

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 is used when you need starter code for charging and mentions selecting a language and framework. However, it provides no explicit when-to-use or when-not-to-use conditions, and does not reference alternative tools or scenarios, leaving usage context only partially implicit.

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