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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the content of the response, not whether the operation is read-only, how pagination works, or any limitations. This is a significant gap for a list tool.

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, short sentence that is easy to scan and gets to the point. However, it is a fragment and could benefit from a verb and a bit more structure, though it is not verbose or wasteful.

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 has one parameter, no output schema, and no annotations, so the description must supply more context. It fails to explain what an 'endpoint' is, the format of the returned data, or how the 'limit' parameter behaves. An agent would be unsure about the response shape and usage.

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 schema has a single 'limit' parameter with 0% description coverage, and the description does not mention it at all. The agent has no information about what 'limit' controls (likely pagination or maximum results) or its constraints, making it impossible to use the parameter correctly.

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 resource (endpoints that charge via x402) and the included attributes (network, asset, price), which distinguishes it from other list tools like list_services or list_tasks. However, it lacks an explicit verb like 'list' or 'retrieve', relying on the tool name for the action.

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 on when to use this tool versus alternatives. The description does not mention use cases, prerequisites, or when another listing tool would be more appropriate, leaving the agent to infer from the name alone.

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