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

No annotations are provided, so the description carries the full burden. It implies a read-only discovery operation but never confirms that, and says nothing about rate limits, authentication, or what the caller actually receives.

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?

It is a single sentence with no padding, but the phrase "WORLD, onboarding and public machine endpoints" is a string of undefined jargon rather than meaningful structure. Short but not front-loaded or informative.

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?

With no annotations and no output schema, the description is the only source of truth, and it fails to say what endpoints are returned, what format they take, or why an agent would call this instead of discover_market.

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?

The tool takes zero parameters, so the parameter dimension carries no semantic burden. Baseline for a zero-parameter tool is 4; there is nothing to document and the description does not mislead about inputs.

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?

"Discover AgentWorld WORLD, onboarding and public machine endpoints" names the resource but the verb is buried in an unfamiliar brand term. It does not clearly state what the tool returns or how it differs from the sibling discover_market, so the agent cannot confidently choose between 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 on when to call this tool, what it is for, or how it relates to discover_market. The word "Discover" is the only hint and it is not actionable.

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