Venice x402 Top-up Requirements

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

No annotations are provided, so the description carries the full burden. It discloses that the tool is a read-only fetch (step-1 requirements) and notes that steps 2 and 3 require a wallet and happen externally. However, it does not mention authentication requirements, rate limits, or whether the fetch is safe. This leaves some behavioral ambiguity.

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 two sentences long, no redundant words, and front-loads the purpose. Every sentence provides essential information without wasted verbiage.

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 2 parameters and no output schema, the description is semi-complete. It mentions the type of data returned but not its structure or format. The optional parameter amount_usd is not explained, leaving potential ambiguity about its effect. Given the simplicity of the tool, the gaps are moderate.

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%, so the description must compensate, but it does not explain the parameters individually. It mentions 'min amount' but does not map it to the parameter amount_usd, nor does it describe wallet_address beyond the schema. The description adds minimal value over the schema alone.

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 fetches step-1 top-up requirements and lists specific items (network, USDC token address, receiver wallet, min amount). It distinguishes from steps 2 and 3 which happen outside the MCP server. The verb 'fetch' and resource 'top-up requirements' are specific and unambiguous.

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 description implies usage context by stating it is step-1 and that subsequent steps occur outside, but it does not explicitly compare with sibling tools like venice_x402_balance or venice_x402_transactions. Nonetheless, it provides clear context for when to use this tool in a multi-step process.

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