route_and_execute

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

Discloses key behaviors like payment from wallet, untrusted content relay, and fee tiers, but lacks details on failure modes or timeouts.

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?

Description is dense and informative, but could be more structured. It front-loads the main concept well.

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?

Explains input and behavior adequately for a routing tool, though return format is only briefly mentioned (untrustedContent).

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 coverage is 100%, and the description adds useful context like maxUsd tier and plain-language task interpretation, going beyond schema descriptions.

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 routes plain-language tasks to external x402 sellers, distinguishing it from sibling tools that are specific utilities.

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?

Provides clear context for use (routing to any external seller) and prerequisites (funded wallet, AGENT_KEY), but does not explicitly mention when not to use it.

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