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

No annotations are provided, so the description carries the full disclosure burden. It reveals that an identity mint occurs and that Bankr /wallet/submit bodies are sent per call, which is useful, but it never states that ETH is spent or transferred, whether the mint is irreversible, what approvals are required, or what failure modes look like. For a value-transferring mutation tool with zero annotation coverage, this is a substantial gap.

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?

Two compact sentences, front-loaded with the key differentiator before the usage condition. Little wasted text, though the 'per-call Bankr /wallet/submit bodies' clause is opaque shorthand that may confuse rather than inform.

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?

A no-annotation, no-output-schema tool with 7 parameters that spends ETH and mints an on-chain identity needs far more than two sentences: cost, reversibility, prerequisites, and return/result shape are all missing. The agent can only guess what a successful call yields.

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 71%, so most parameters are already documented. The description adds context for agentURI (custom registration file for the mint) and hints at a per-call submit body, but says nothing about token, referrer, slippagePct, or how agentId interacts with the mint path. Baseline 3 is appropriate.

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 name plus 'Same as agentpad_buy, plus a custom ERC-8004 agentURI for the identity mint' conveys that this is a buy-and-register composite, but the core action is defined only by reference to a sibling. An agent must read agentpad_buy to learn what the primary operation actually is. It distinguishes itself from siblings but only relative to them, not absolutely.

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?

'Use when your wallet is new to AgentPad' gives one clear positive selection condition and implicitly routes existing wallets to agentpad_buy. There are no explicit exclusions, prerequisites (funding, approvals), or note about what happens if the wallet is already registered.

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