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

With no annotations, the description itself carries the behavioral burden and does disclose meaningful traits: a 302 redirect to start_here.hop, returning docs/CLI/remote MCP hops, and discarding task text. It omits a clear side-effect profile, but the disclosures go well beyond what the name or schema alone would convey.

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 compact, front-loaded with the main purpose, and contains no filler. The important caveat 'Task text discarded' is placed last rather than earlier, but the overall structure is efficient.

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 description gives high-level output categories but, with 9 optional parameters and no output schema or annotations, an agent is left guessing which parameter to populate or what the returned hops/docs look like. It is more complete than a stub, but not fully sufficient for correct invocation.

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 description coverage is 100%, so the parameters are already documented and the description does not need to compensate. The description adds only the global caveat that task text is discarded, which is useful but not parameter-specific; baseline 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 opens with a specific verb ('Find') and a specific resource ('public pay-per-call tool gateway (Monid)'), and the mention of returned artifacts distinguishes it from sibling check-utilities. It is not a 5 because 'Monid' and 'pay-per-call tool gateway' remain unexplained jargon, but an agent can infer this is a discovery/index tool.

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 guidance about when to use this tool versus sibling tools; no sibling names are referenced and no exclusions are stated. 'Follow start_here.hop first' is an internal step, not a selection criterion.

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