create_instant_agent_wallet

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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: the wallet is 'temporary' with '24-hour validity' and has a 'Price: $0.50', which are crucial for cost and time awareness. However, it doesn't cover permissions, rate limits, or what happens after expiration.

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?

Front-loaded with the core action, followed by structured sections for Args, Returns, and Price. Each sentence earns its place, but the 'Args' section could be integrated more smoothly, and there's minor redundancy in listing options.

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?

Given the tool's moderate complexity (1 parameter, no annotations, but with output schema), the description is fairly complete. It explains the purpose, parameter semantics, return value, and cost. The output schema likely covers return details, so no need to elaborate further. However, it lacks error handling or prerequisite info.

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. It adds meaningful semantics: 'purpose' is explained with options 'trading, testing, payment', which clarifies beyond the schema's generic 'Purpose' title and 'general' default. This covers the single parameter well, though it doesn't mention the default value.

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 action ('create a temporary agent wallet') and resource ('wallet'), with the qualifier 'instantly' and 'for quick operations' providing useful context. It distinguishes from the sibling 'create_agent_wallet' by emphasizing speed and temporariness, though it doesn't explicitly contrast them.

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 versus alternatives like 'create_agent_wallet' or other wallet-related tools. The mention of 'quick operations' and '24-hour validity' implies transient use cases but lacks clear when/when-not directives or named alternatives.

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