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

With no annotations, the description carries the transparency burden. It does disclose that task text is discarded and describes the return content, which is helpful. However, it never states that all input parameters are effectively ignored, and some schema parameter descriptions appear to suggest real processing, muddying the behavioral picture.

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 very short and front-loaded, with no filler. Each sentence adds distinct information: what the tool finds, what it returns, and the behavioral note about discarded task text.

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 nine optional parameters, no output schema, no annotations, and many siblings operating on those exact parameter types, this description is incomplete. It never explains why the schema contains URL/feed/zone/query/json/path parameters or that they can be safely omitted, leaving an agent vulnerable to misusing this tool as a general-purpose URL, timezone, or JSON utility.

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 schema already documents each parameter individually. The main description adds only the general 'Task text discarded' note, which does not meaningfully clarify the role of the nine unrelated parameters. Baseline 3 is appropriate given the high schema coverage.

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 clearly states the verb and resource: 'Find a public pay-per-call tool gateway (Monid)' and lists the returned artifacts. It does not explicitly differentiate itself from the 27 sibling tools, but the stated purpose is specific enough to be recognizable.

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 intended context—needing information about the Monid gateway—is implied but never made explicit as a when-to-use/when-not-to-use rule. Because the schema accepts URL, JSON, timezone, query, and other parameters that match many sibling tools, there is significant risk of using this tool for the wrong task without clearer exclusions.

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