register_agent

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

With no annotations provided, the description carries the transparency burden. It discloses key behavioral traits: the API key is shown only once (so it must be saved securely), and no prior authentication is needed. This goes beyond basic purpose and gives critical operational details, though it doesn't describe the exact response format or post-registration actions.

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 three sentences long, front-loaded with the core purpose, and every sentence adds value (purpose, one-time key warning, auth note). No wasted words or redundant information.

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 straightforward registration tool with three parameters and no output schema, the description covers the essential context: what the tool does, the one-time API key behavior, and authentication requirements. It lacks an explicit mention of the response contents but implies them, making it reasonably complete for the tool's complexity.

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 has 100% coverage, with all three parameters (name, fee_wallet, description) described adequately. The tool description itself adds no additional parameter semantics beyond what the schema provides, so a baseline score of 3 is appropriate.

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's purpose: registering as a new agent on DumbMoney to obtain an API key for creating tokens. This distinguishes it from sibling tools like list_tokens or get_my_agent_info, making its function evident.

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 provides clear context for when to use this tool (when you need to register and get an API key) and mentions that no authentication is required. However, it does not explicitly exclude alternate tools or explain when not to use it, such as when you already have an API key.

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