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 does indicate a read-style behavior by saying Return, which implies no side effects. But it says nothing about caching, freshness, scope limitations, required permissions, or error behavior, leaving gaps about how the call behaves beyond being a query.

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?

One sentence, front-loaded with the action verb, and every remaining word contributes a distinct output category. There is no fluff or repetition, making it appropriately concise for a capabilities overview.

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 output schema and no annotations, the description is the only source for what the tool returns. It lists four high-level categories, but uses dense jargon such as MUJ428 canonical machine discovery surfaces and Trust Gravity routing, and does not explain the shape of the response or point to sibling tools for deeper detail. This is adequate but not complete.

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 has zero parameters and the schema is empty, so the baseline is 4. There are no parameter semantics to describe, and the description correctly focuses on return content rather than 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?

The description states a specific verb (Return) and names four concrete resource areas: machine discovery surfaces, payment-rail discovery, Trust Gravity routing, and recommended adoption path. However, it does not explicitly differentiate itself from siblings like get_payment_rails or find_trust_capabilities, leaving some overlap ambiguity.

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 use this tool versus its siblings. It does not mention alternatives, conditions, exclusions, or whether this is the preferred entry point for a general overview. The agent must infer usage solely from the name and content list.

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