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

There are no annotations, so the description carries the full burden of behavioral disclosure. It explains the core function but does not disclose return format, required inputs, data sources, or whether the estimate is live or approximate. This is thin for a tool that an agent must invoke correctly.

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 with no filler. It communicates the core purpose immediately and does not waste tokens.

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 tool with 5 optional string parameters, no output schema, no annotations, and a large field of DEX-related siblings, this one-sentence description is not enough. An agent would struggle to know which parameters to provide, what the response looks like, or how this tool differs operationally from other DEX tools.

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?

Schema description coverage is 100%, which gives the baseline of 3 even though the tool description does not add parameter-level meaning. However, the schema descriptions are generic ('Size to process', 'Amount to process', 'Address to process') and do not clarify the relationships or required combinations of size, amount, amountUsd, and address.

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 identifies the tool as a DEX liquidity depth tool that estimates slippage for large orders across DEX pools. This distinguishes it from sibling tools like x402-dex-price and x402-dex-arb, which serve different purposes.

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 phrase 'for large orders' gives some implicit guidance about when the tool is relevant, but the description does not explicitly mention alternatives or state when not to use it. With many DEX-related sibling tools, this is a noticeable gap.

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