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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does disclose that it returns CLI setup, how-it-works, skill file, and remote MCP hops, and that 'Task text discarded.' This gives some transparency about outputs and input handling. However, it doesn't mention side effects, network access, error behavior, or authentication requirements. Given zero annotations, this is partially transparent but not comprehensive.

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 zero waste. The primary purpose is front-loaded, and the discard note is secondary. It's appropriately concise and structured.

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, no annotations, and 27 siblings, the description is incomplete. It doesn't clarify how the parameters relate to the tool's function, what a successful call returns in detail, or how it differs from similar hint tools. An agent would be uncertain about what parameters to supply and what the tool actually does beyond returning static info.

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 all 9 parameters are documented in the schema. The description adds no parameter-specific information; it doesn't explain how parameters map to the tool's function (e.g., which parameter is needed for what). Baseline 3 is appropriate since the schema does the heavy lifting, but the description doesn't enhance 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 description states a specific action: 'Find a public pay-per-call tool gateway (Monid)' and lists the outputs (CLI setup, how-it-works, skill file, remote MCP hops). This is a clear verb+resource combination. However, it doesn't differentiate from sibling hint tools like 'lib-docs-hint' or 'weather-hint', and the exact operation (does it fetch remote info?) is ambiguous. Still, the core purpose is identifiable.

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 alternatives. With 27 sibling tools, many likely handling similar URL/parameter checks, the description doesn't state exclusions or alternatives. It implies usage for finding a Monid gateway but doesn't specify prerequisites or when not to use it.

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