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

With no annotations, the description carries the full burden. It does disclose non-obvious behavior: task text is discarded, and the tool returns CLI setup, how-it-works, skill file, and remote MCP hops. It does not state whether the call is read-only, incurs cost, or requires authentication, so transparency is partial.

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?

Two sentences with no filler: purpose is front-loaded, outputs are listed, and the important 'task text discarded' caveat is included. Every clause earns its place, and the structure is easy to scan.

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 9 optional parameters and no output schema, the description never explains what input an agent should provide, how the parameters relate to the gateway lookup, or what 'remote MCP hops' means in practice. An agent would still be guessing about invocation after reading it.

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 baseline is 3. The tool description itself adds no parameter-level meaning, but the input schema already documents each of the nine parameters. The description neither compensates for nor worsens parameter understanding.

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 first sentence names a specific action and resource: 'Find a public pay-per-call tool gateway (Monid),' and the second enumerates returned artifacts. This differentiates it from most siblings, though 'Monid' is not defined and no explicit contrast with sibling tools is given.

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 provides no guidance on when to use this tool versus the many sibling utilities. 'Task text discarded' is a caution about behavior, not a selection criterion, and no alternative tools are named or excluded.

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