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

With no annotations, the description carries the full burden. It only states 'Task text discarded' and hints that some parameters are discarded, but does not disclose side effects, dependencies, or what the tool does with the non-discarded parameters. The behavior is largely opaque.

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 very short and front-loaded, but its brevity is due to vagueness rather than efficiency. It contains two sentences but little useful information, so it is concise but not well-structured for decision-making.

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?

With 9 optional parameters, no output schema, and no annotations, this description is grossly insufficient. It does not explain what the tool returns (beyond vague items), how to use the parameters, or when it applies. An agent cannot correctly invoke this tool with confidence.

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%, but the tool description itself says nothing about the parameters. The schema descriptions are individual and often say 'discarded', yet the description does not explain how they integrate or which ones are relevant. The description adds no meaning beyond the schema, failing to compensate for the lack of overall parameter usage context.

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 says 'Find a public pay-per-call tool gateway (Monid)' and lists outputs, but does not explain how the 9 input parameters map to this action. It is unclear what the tool actually does operationally with the parameters, making it hard for an agent to select it based on purpose.

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 on when to use this tool versus any of the 28 siblings. No context, no exclusions, no mention of alternative tools. An agent has no basis to choose it over similar tools like 'web-fetch' or 'citation'.

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