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

The description adds a notable behavioral detail: 'Task text discarded', which tells the agent not to expect task-specific processing. It also lists return components. However, without annotations, it does not disclose failure modes, authorization needs, or possible pay-per-call cost implications.

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 three short sentences with no filler or redundancy. The main purpose is front-loaded, and the behavioral caveat is placed last without bloating the text.

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 leaves a significant invocation gap: six unrelated params are present, the schema marks them as discarded, and 'task text' is not a schema param, so it is unclear what to actually pass. There is no output schema, and return values are only summarized, so an agent may not know what to expect or how to call this correctly.

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 coverage is 100%, so the parameters are already documented; the description adds no parameter-level meaning. Since the schema descriptions themselves say the params are discarded or validated only for shape, the description does not need to repeat those details.

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 action, 'Find', and a specific resource, 'public pay-per-call tool gateway (Monid)', and lists the returned artifacts: CLI setup, how-it-works, skill file, and remote MCP hops. It is clear about the tool's purpose, though it does not explicitly differentiate from 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?

Usage is only implied: the agent would select this when it needs the Monid gateway. There is no explicit 'use this instead of X' or 'do not use this when Y' guidance, which is a gap given the large set of sibling validators.

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