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

No annotations are provided, so the description carries the full behavioral disclosure burden. The verb 'Describe' signals a read-only, informational operation, which is a useful trait, but the description does not explicitly state that it has no side effects, what form the response takes, or whether any integration/auth context is included.

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 a single, front-loaded sentence that enumerates the covered topics without filler or repetition. Every part contributes to making the tool's scope clear.

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 simple, zero-parameter informational tool with no output schema, the description adequately covers the content an agent needs to know before invoking it. A small gap is the absence of any indication of the response structure or relationship to preflight_safe_swap, but nothing about actually calling the tool is underspecified.

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 input schema has zero parameters, so there is no parameter detail for the description to add. A baseline of 4 is appropriate because the tool cannot have parameter documentation gaps.

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 tool's function with the verb 'Describe' and names the specific resource: Preflight SafeSwap capabilities, pricing, discovery endpoints, and integration details. It is distinguishable from the sibling preflight_safe_swap as an informational tool, though it does not explicitly contrast itself with that sibling.

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 description implies the agent should call this when it needs to learn about Preflight SafeSwap's capabilities, pricing, endpoints, or integration details. However, it provides no explicit when-to-use versus the sibling tool preflight_safe_swap, and no when-not guidance.

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