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

With no annotations provided, the description carries the full burden of disclosing behavior. It does state that it returns CLI setup, how-it-works, skill file, and remote MCP hops, and that task text is discarded. However, it does not disclose whether the operation is read-only, what happens with invalid inputs, how the parameters are consumed, or what the actual side effects are. The confusing 'Task text discarded' statement (no task parameter exists) adds ambiguity rather than clarity.

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 and reasonably front-loaded with the purpose. However, the sentence 'Task text discarded' is confusing and not tied to any parameter, wasting a few words. Overall it is compact and readable, but the odd mention detracts slightly from efficiency.

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 tool has 9 parameters, no output schema, and no annotations, yet the description is minimal. It does not explain how the parameters are combined, what the expected return format is, or under what circumstances the tool is useful. For a complex tool with many inputs, this description is inadequate for an agent 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%, with each of the nine parameters having a descriptive line. The tool description itself adds no additional meaning about how the parameters are used together or what their role is in finding the gateway. It only repeats the discard note, which is already implied for several parameters. Baseline 3 is appropriate because the schema does the heavy lifting, and the description provides marginal extra context.

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 verb ('Find') and resource ('a public pay-per-call tool gateway (Monid)'), and lists what it returns. However, it does not clarify how the nine unrelated parameters (url, city, feed, host, json, etc.) relate to finding that gateway, making the purpose ambiguous. It also does not distinguish itself from any of the 26 sibling tools, leaving the agent unsure of when this tool is appropriate.

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?

No guidance is given on when to use this tool versus any alternative. The description does not mention any sibling tool, conditions for use, or exclusions. An agent cannot determine if this is the right tool for a given task based on the description alone.

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