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

No annotations are provided, so the description carries the full burden, and it does add genuinely useful behavioral context: the $0.004 USDC cost per successful call, which signals this is a paid external operation. However, it omits other important traits such as whether it is read-only, rate limits, and what (beyond the listed artifact types) is returned.

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?

Two tight sentences with the capability front-loaded and the pricing constraint appended after. No filler or redundancy.

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 single-parameter tool with no output schema, the description communicates the artifact types it returns (docs, portal, base URLs, auth docs) and cost, which is nearly everything an agent needs to decide and call. Slightly short of complete because it does not clarify output structure or reliability of the discovered URLs.

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?

Only one parameter ('url') exists and schema coverage is 100%, with the schema itself explaining it as a public HTTP(S) URL to inspect, resolve, or compare. The description adds no parameter-specific detail, so the baseline 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?

States a specific verb ('Find') with concrete resources: API docs, developer portal, candidate base URLs, and auth docs. An agent can tell this is a discovery/inspection tool, though it never names how it differs from siblings like domain_preflight or release_asset_resolve, which also resolve web resources.

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?

There is no explicit when-to-use guidance, no prerequisites, and no mention of when to prefer this over the sibling preflight/resolve tools. The discovery intent is only implied by the resource list.

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