gate_find_endpoints

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

Discloses important behavior: read-only, free, entries verified by machine. With no annotations, this provides adequate transparency. Could note pagination or rate limits, but still good.

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?

Three sentences, front-loaded purpose, no fluff. Every sentence adds value: purpose, return fields, workflow, data quality.

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 3 optional params and no output schema, the description covers what the tool returns and its place in the workflow. could mention default limit behavior, but still complete enough.

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 coverage is 100%, so baseline is 3. The description adds minimal extra semantics beyond schema descriptions, but it does tie params to the tool's purpose (finding paid sources).

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?

Clearly states it browses a registry of x402-priced endpoints, lists returned fields (url, price, etc.), and distinguishes from siblings like gate_get_price and gate_fetch by describing the workflow: find endpoint, then call those tools.

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 it ('find a paid data source without being handed the URL') and what to do next ('call gate_get_price or gate_fetch'). Could be improved by mentioning when not to use it compared to sibling search tools.

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