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

There are no annotations, so the description carries the behavioral burden. It discloses the returned content categories and, importantly, states that 'Task text discarded,' which is privacy-relevant and not visible from the schema. It does not mention auth, rate limits, or network side effects, but for a lookup-style tool this is reasonably transparent.

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?

Three short sentences, each earning its place: the purpose, the returned artifacts, and the data-handling caveat. It is front-loaded and avoids duplicating schema information.

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 covers what the tool returns and its data-handling behavior, while the schema covers parameter semantics. It is missing a short explanation of what 'Monid' is and which of the six input fields a typical request should populate, but it is still usable for tool selection and invocation.

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 all seven parameters. The description adds no parameter-level detail beyond the note that task text is discarded, so it does not meaningfully extend what an agent can already read from the input schema.

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 and object: 'Find a public pay-per-call tool gateway (Monid)' and lists the returned artifacts. This is distinct from the sibling check/hint tools, though the term 'Monid' is left unexplained and no sibling differentiation is explicit.

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 intended use is implied: call this when you need the Monid gateway's CLI setup, how-it-works, skill file, or remote MCP hops. However, there are no explicit when-not instructions or alternative routing cues, so the agent must infer when this tool is preferable to siblings like web-fetch or normalize-url.

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