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

With no annotations, the description carries full burden. It discloses cost ($0.001 USDC) and wallet-free nature, but omits any details about what the safety check does, return values, potential side effects, or error conditions. This is minimal and insufficient for an agent to anticipate behavior.

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 sentence, highly concise and front-loaded with key qualifiers ('Wallet-free', 'approved-token', 'safety preflight'). It wastes no words while including cost, which is useful. However, it is so brief that it sacrifices clarity on behavioral details.

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?

The tool has 6 parameters, no annotations, and no output schema, yet the description provides almost no operational context. It does not explain what a 'preflight' involves, what success/failure looks like, prerequisites, or how the cost is applied. This is severely incomplete for an agent to invoke 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 0%, and the description does not mention any parameters. The agent is left without any meaning for 'amount', 'intentId', 'referralCode', or 'sourceAgentId'. Even though from/to have enums, the description adds nothing about how these are used or formatted.

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's function as a 'swap safety preflight' for approved tokens on Base, and adds constraints like wallet-free and cost. It distinguishes from siblings like get_safe_swap_quote (which likely provides quotes) and verify_swap_execution (which verifies after execution), but could be more explicit about what 'safety preflight' actually returns.

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 explicit guidance on when to use this tool vs alternatives. It implies use before a swap but does not mention exclusions, prerequisites (beyond approved tokens), or when to choose get_safe_swap_quote or verify_swap_execution instead.

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