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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotenceHint=true, and the description adds a meaningful behavioral trait: 'Task text discarded.' It also discloses that the tool returns remote MCP hops, which is useful context not present in annotations. No contradiction exists.

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. The first sentence states purpose, the second lists return contents, and the third gives a data-handling caveat. Each sentence 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?

There is no output schema, so the description appropriately lists return contents. It does not explain what 'Monid' is or detail invocation prerequisites, but the schema covers all parameters and annotations cover safety. It is adequate for a read-only discovery tool.

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?

All seven parameters have schema descriptions, so schema coverage is 100% and the baseline applies. The description adds no parameter-specific detail, but the schema already fully documents each parameter.

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 uses a specific verb ('Find') and names the exact resource ('public pay-per-call tool gateway (Monid)'), then lists concrete outputs ('CLI setup, how-it-works, skill file, and remote MCP hops'). This makes the tool's function clear and distinguishes it from sibling fetch/URL tools even though the tool name itself is generic.

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 establishes a clear context for use—finding the Monid pay-per-call gateway—but it does not explicitly state when not to use it or name alternatives. Usage is implied rather than directly contrasted with sibling tools like web-fetch or fetch-status.

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