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

With no annotations to help, the description provides limited behavioral detail. It mentions outputs and that certain inputs are 'discarded', but it does not clarify side effects, read-only nature, failure modes, or why some parameters are ignored, making behavior 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 short and to the point, but it sacrifices clarity for brevity. Key terms are unexplained and the relationship between the listed outputs and the parameters is unclear, so the conciseness does not effectively aid understanding.

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 tool has no output schema and the description provides only a vague list of return items. Critical details such as input-output mappings, side effects, error behavior, and the meaning of 'Monid' are absent, making the description incomplete for reliable use.

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?

While all nine parameters have schema descriptions, most are brief and some are confusing or self-contradictory (e.g., 'discarded after shape check', 'no disk access', 'discarded after length check'). The descriptions do not clarify how parameters like city, zone, or query relate to the tool's core purpose, adding little real semantic value.

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 the tool finds a 'public pay-per-call tool gateway (Monid)' and lists return items, giving a general sense of purpose. However, 'Monid' is unexplained and the exact function remains ambiguous, making it only moderately clear.

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?

No guidance is given on when to use this tool versus any of the 26 sibling tools. The description does not mention conditions, alternatives, or typical scenarios, leaving the agent without sufficient direction for selection.

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