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

With no annotations, the description carries the transparency burden. It does reveal an important behavior: 'Task text discarded' and parameter descriptions say values are discarded after shape checks, suggesting no retention. However, it does not state whether the call is read-only, whether it triggers external/paid requests, or what side effects may occur.

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 front-load the main purpose and most actionable detail. There is no filler or redundant restating of the tool name or schema.

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 or annotations, so the description must explain both outputs and invocation context; it lists return artifacts but does not describe the response format or parameter usage. The discarded-parameter behavior is implied but an agent is not told whether it can call with no arguments or which shape to provide.

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 coverage is 100%, so the baseline is 3; each parameter has a description. The tool description adds little beyond the schema, and it does not explain whether any of the six heterogeneous parameters is required or preferred, though the 'discarded' descriptions make them appear non-essential.

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 resource ('public pay-per-call tool gateway (Monid)') and lists concrete return artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It is clear about the tool's function, though it does not explicitly name sibling tools or contrast itself with them.

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 alternatives such as web-fetch, normalize-url, or validate-json. The description implies a lookup scenario but gives no exclusions, prerequisites, or conditions that should route an agent to this tool.

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