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

With no annotations, the description carries the behavioral burden. It usefully discloses that 'Task text discarded' and that the call returns documentation-like artifacts. However, it does not state whether the tool is read-only, makes network calls, requires authentication, or what happens when multiple parameters are supplied.

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 only three sentences and every sentence earns its place: what it finds, what it returns, and a privacy-relevant behavior. It front-loads the primary purpose before listing outputs.

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?

Despite the concise wording, the tool is not fully specified: there are 9 optional parameters, no output schema, no annotations, and a large sibling set, yet the description does not explain how to choose parameters or what the returned artifacts look like. The odd disconnect between the description and the schema's generic parameters makes the definition incomplete for reliable 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 per-parameter meaning is already provided by the schema. The tool description adds no cross-parameter guidance, such as which of the nine optional parameters is relevant or how parameters map to the returned 'CLI setup' or 'remote MCP hops.' Baseline 3 applies because the schema carries the parameter documentation burden.

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 states a specific verb and resource: 'Find a public pay-per-call tool gateway (Monid),' and lists concrete return items such as 'CLI setup, how-it-works, skill file, and remote MCP hops.' It is clear about the tool's general function, though it does not compare against sibling tools or explain what 'Monid' is.

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?

The description gives no guidance on when to use this tool instead of the many sibling tools, nor does it mention any prerequisites or expected inputs. 'Find' implies discovery, but there is no explicit context like 'use when you need the tool gateway index' or 'use instead of web-fetch.'

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