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

The annotations already indicate this is not read-only and not destructive, and the description reinforces the side effect by saying it 'actually places the order.' It adds useful behavioral context: RAVN decodes the venue from quoteToken, routes automatically, and returns a statusRef for polling. It doesn't cover failure modes, but the annotation profile covers the key safety expectations.

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 dense but efficient: the key condition is front-loaded, each sentence carries distinct information, and there is no filler or repetition of schema content.

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?

With a rich schema and output schema present, the description covers the remaining contextual gaps: when the tool is applicable, what inputs are involved, how venue routing works, and how to follow up via ravn_status. An agent has everything needed to invoke it correctly.

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%, so the description doesn't need to re-explain parameters. It adds mild value by linking parameters to their sources (signature from ravn_execute, quoteToken from ravn_quote), but this is context rather than essential semantics beyond the schema.

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 opens with the exact condition ('For a SIGNATURE-type ravn_execute result only') and states the core action: submit collected signatures to actually place the order. This clearly distinguishes it from sibling tools like ravn_execute, ravn_quote, and ravn_status.

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?

It explicitly scopes when to use the tool ('SIGNATURE-type ravn_execute result only') and tells the agent what inputs are relevant (signature over typedData, approvalSignature if present). It also explains the routing behavior so the agent knows it doesn't need per-venue endpoints, and it points to ravn_status for polling.

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