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

Annotations already establish this as a read-only, idempotent, non-destructive operation. The description adds meaningful behavioral context beyond that: the tool is non-custodial, the agent signs with its own key, and it returns setup artifacts rather than executing a trade. No contradiction with annotations.

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 dense sentence that front-loads the core value ('Everything an agent with its own wallet needs to trade') and then itemizes the contents. Every clause earns its place, with no filler or redundancy.

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?

Given zero parameters, no output schema, and rich annotations, the description covers the essential content: chain, collateral, builder code, signer URL, attestation steps, fees, and SDK snippet. It could briefly mention the output format or how the snippet is returned, but for an informational tool this is nearly 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, so the baseline is 4. There is nothing for the description to clarify about parameter meaning, and the empty schema is consistent with a static informational tool.

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 the tool provides a complete trading setup package: chain, collateral, builder code, signer URL, attestation steps, fees, and a TypeScript snippet. The verb is implicit but the resource is concrete, and the title 'How to trade through predictDEX' reinforces the purpose. It is clearly distinct from sibling tools like get_orderbook or create_trade_link.

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 'Everything an agent with its own wallet needs to trade' gives clear context about the intended user and scenario. However, it does not explicitly state when to use this tool versus alternatives such as create_trade_link or attest_agent, nor does it mention any exclusions or prerequisites beyond having a wallet.

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