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

With no annotations, the description carries the full burden and does disclose cost behavior ('free, never x402-gated') plus the return shape (`executable` flag, hubs, launchpads). It omits pagination, auth, and error behavior, but for a read-only listing the disclosure is solid.

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?

Front-loaded purpose followed by three tight bullets (cost, returns, next step). Every line carries distinct information with zero padding.

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?

No annotations and no output schema, so the description must explain returns and cost — which it does, including the key `executable` flag and the hand-off to the quote tool. Minor gaps (auth, pagination, error cases) keep it from 5.

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?

Zero parameters with 100% schema coverage; there is nothing to document, so the baseline 4 applies. The description adds no parameter-level detail, which is correct here.

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?

Specific verb (Lists) and resource (DEX venues, hub tokens, launchpads) scoped to 'this deployment indexes'. An agent can tell it apart from quote/swap siblings functionally, though no sibling is named explicitly.

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 'Next' line gives concrete downstream usage: feed venue ids into POST /trade/v1/quote's `venues`/`excludeVenues`. No explicit when-not-to-use or named alternative, so it stops short of 5.

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