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

With no annotations, the description carries the transparency burden. It does disclose one important behavior ('Task text discarded') and hints at public availability, but it fails to mention side effects, whether inputs affect results, or that most parameters are only shape-checked and then discarded. The schema reveals this, but the description itself is incomplete about behavioral traits.

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 two short sentences with no filler. Purpose is front-loaded, followed by return contents and a key caveat. Every sentence earns its place, and the phrasing is tight and scannable.

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 having nine optional parameters, no output schema, and no annotations, the description does not explain which parameter(s) should be supplied or what the returned CLI setup, how-it-works, skill file, and remote MCP hops actually contain. It also leaves the meaning of 'Monid' ambiguous, so an agent cannot confidently invoke the tool 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 description coverage is 100%, so the schema already documents every parameter. The description adds no parameter-level meaning and does not clarify how the nine optional parameters relate to the tool's purpose. Per the rubric, baseline 3 is appropriate when the schema does the heavy lifting.

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 names a specific action ('Find') and a specific resource ('a public pay-per-call tool gateway (Monid)'), and lists the returned artifacts. This distinguishes it from the sibling validation/lookup tools, though 'Monid' and the exact nature of the return payload remain unexplained.

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 alternative. The description implies it should be used to discover Monid setup information, but it never states concrete conditions, prerequisites, or exclusions, leaving the agent to infer the intended context.

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