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

With no annotations, the description carries the behavioral burden. It does disclose an important side-effect ('Task text discarded') and lists what is returned, which goes beyond the schema. However, it does not clarify cost, network side effects, authentication, persistence, or what 'remote MCP hops' means despite the 'pay-per-call' implication.

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 compact and front-loaded: purpose, return contents, and a key behavioral caveat each get one sentence. There is no filler or repetition of schema details.

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?

Despite a high schema coverage, the tool is complex: nine optional parameters, no output schema, no annotations, and many siblings. The description does not explain how to invoke the tool meaningfully, what to do with the returned CLI setup/skill file/MCP hops, or why the parameters are accepted if most inputs are discarded. An agent would struggle to decide whether and how to call it correctly.

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 baseline is 3. The description adds only the global note that task text is discarded, without explaining how the nine optional parameters relate to each other or which should be supplied. It does not compensate for the absence of parameter-usage guidance, but the schema already documents each field individually.

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 a concrete resource ('public pay-per-call tool gateway (Monid)') plus what it returns. It is distinguishable from the sibling shape-check/hint tools, though 'Monid' is unexplained and the connection to the tool name 'agent-tool-index' is not made 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?

There is no guidance about when to use this tool instead of a sibling, no exclusions, and no indication of what kind of query or input should trigger it. The only hint is the resource description, but an agent gets no decision rule for selecting this over similar discovery/fetch tools.

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