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

The description discloses key behavioral traits: it is 'simulated' (not a real transfer), 'unsigned' (won't execute on-chain), and costs $0.10 USDC. However, it does not explain what 'bounded' means, what the response looks like, whether it has side effects beyond the charge, or any rate limits. With no annotations to offload this burden, the description provides some but not enough disclosure.

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 concise sentence that front-loads the core purpose and cost. It is appropriately short, though it could be structured slightly better by separating the cost note. No filler or unnecessary words.

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 7 parameters, no output schema, and no annotations, the description is severely incomplete. It omits return values, parameter explanations, edge cases, and any contextual information about how this simulated transfer interacts with other tools. The agent has little to go on for correct invocation.

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 0% and the description provides no information about any of the 7 parameters (token, amount, sender, recipient, intentId, referralCode, sourceAgentId). The agent must rely entirely on the bare schema, which lacks descriptions, making parameter usage ambiguous and error-prone.

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 prepares a 'bounded, simulated unsigned Base token transfer' and mentions it costs $0.10 USDC, giving a specific verb and resource. It is distinct from sibling tools like preflight_transaction or get_safe_swap_quote, though it does not explicitly describe what 'prepare' returns or how it differentiates from these alternatives.

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?

No guidance is provided on when to use this tool versus alternatives such as preflight_transaction or check_base_swap. The description gives no context about prerequisites, appropriate scenarios, or exclusions, leaving the agent without direction on tool selection.

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