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

No annotations are supplied, so the description carries the full behavioral burden. It vaguely implies a read-style discovery call but says nothing about what is returned, whether it requires authentication, or how it differs operationally from its sibling, leaving the agent under-informed.

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?

A single compact sentence with no filler, and the target of the discovery is front-loaded. It is efficient, though it reads as a fragment rather than a complete operational statement.

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, no output schema, and no parameters, the description is the only information source, yet it provides minimal detail about the result of the discovery or how it relates to the sibling tool. For a discovery entry point it should say more about what it returns or lists.

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 schema has zero parameters, so there is nothing for the description to clarify. Per the baseline for parameterless tools, this dimension sits at 4 by default.

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 gives a verb ('Discover') and a named target ('AgentWorld MARKET machine-to-machine service economy'), and the word 'separate' faintly distinguishes it from the sibling discover_agentworld. But it is largely marketing phrasing rather than a concrete statement of what the tool actually does or returns, so an agent cannot fully tell what 'discover' yields here.

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 explicit statement of when to call this versus the sibling discover_agentworld; the only hint is the word 'separate'. No prerequisites or exclusions are given, so the routing decision between the two discovery tools is left to inference.

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