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

With no annotations, the description carries the behavioral burden. It adds one meaningful disclosure ('Task text discarded') and implies a read-only lookup, but it does not mention authentication, network access, cost implications of 'pay-per-call', or whether it modifies anything.

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 with purpose first and no filler. It uses unexplained jargon ('Monid', 'MCP hops') but otherwise every sentence earns its place.

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?

For a tool with 9 optional parameters, no output schema, no annotations, and 27 siblings, the description leaves the invocation pattern and return format underspecified. An agent cannot tell whether it should pass a URL, city, or nothing, or when to prefer this tool over related hints/validators.

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?

Although schema-level coverage is 100%, the description does not connect any of the nine optional parameters to the stated purpose of finding a Monid gateway. Each parameter is described individually in the schema, but their relationship to CLI setup/MCP hops is unclear; the tool can be invoked with no required params, yet the description never says that.

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 names a specific action and object ('Find a public pay-per-call tool gateway (Monid)') and lists concrete outputs (CLI setup, how-it-works, skill file, remote MCP hops). It does not explicitly contrast with siblings, and 'Monid'/'MCP hops' are 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?

Usage context is implied: call this when the agent needs the Monid gateway setup or pay-per-call tool routing. There are no when-not-to-use statements or alternative sibling tools named, so guidance is only implicit.

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