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

The description goes beyond the readOnly/idempotent annotations by explicitly stating 'Task text discarded' and enumerating the returned artifacts. This usefully warns the agent that conversational/task input is ignored and that the tool only returns documentation hop information. No contradiction with annotations.

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 sentences with no filler. The core purpose is front-loaded, the output list is concrete, and the discard warning is a meaningful additional constraint rather than repetition.

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 names the output artifacts, which is important since there is no output schema. However, it does not explain what Monid is or what 'remote MCP hops' means, and it gives no context for when an agent would need this gateway. Given the 7-parameter surface and missing output schema, a bit more context would help.

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 every parameter is already documented structurally. The description adds no additional parameter guidance, but the baseline 3 is appropriate because the schema carries the parameter semantics.

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 a specific resource ('public pay-per-call tool gateway (Monid)'), and lists concrete outputs (CLI setup, how-it-works, skill file, remote MCP hops). It is distinct from the sibling tools, none of which mention Monid or a pay-per-call gateway. However, 'Monid' and 'pay-per-call tool gateway' are left unexplained, so it is not a 5.

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 implies the tool is for retrieving setup/usage information about the Monid gateway, but it never explicitly says when to use it or when not to. It also provides no alternatives or exclusions, leaving the agent to infer the appropriate context from the tool name and description.

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