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

With no annotations provided, the description must carry the burden of disclosure. It explicitly mentions 'public' and uses 'Get', implying a read-only, open-access operation. However, it does not describe the response structure or any potential caveats, but for a simple info endpoint this is somewhat sufficient.

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 a single, concise sentence that lists the included data types. It is not verbose, though 'wallet-first notes' is jargon that could be clearer.

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 the simplicity (no parameters, no output schema), the description provides a reasonable high-level overview of the tool's data coverage. It lists specific registry-related items, making it mostly complete, though the return format isn't detailed.

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 tool has zero parameters, so the schema coverage is trivially 100%. The description adds no parameter details, but none are needed. The 0-parameter baseline is 4.

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 identifies the tool as retrieving public ERC-8004/Solana-8004 registry information, naming specific data categories such as supported networks, worker routes, and wallet-first notes. It uses a specific verb and resource, though it doesn't explicitly differentiate from sibling tools like list_networks.

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?

No guidance is provided about when to use this tool versus alternatives like list_networks or get_agent. There is no mention of scenarios where this tool should be preferred or avoided.

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