gm_create_wallet

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

With no annotations, the description carries full responsibility and excels: it discloses that the private key is returned to the caller, never stored/logged/transmitted, the wallet starts empty, and there is no recovery if the ritual is skipped. It even specifies the chain ID (57073) and the need for gas.

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?

Although lengthy, every sentence carries essential information—purpose, security warning, and actionable ritual steps. The structure front-loads the core function and then details the required follow-up, with zero filler.

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 description covers the purpose, security implications, the ritual, the chain, and the empty state. The only minor gap is that it doesn't explicitly enumerate the exact return values (e.g., address and private key format), but it implies them through the ritual language. Given the tool's simplicity and lack of output schema, this is a strong score.

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?

The tool has zero parameters and the schema is empty, so the baseline is 4. The description explicitly states 'No arguments', which reinforces the schema and removes any ambiguity.

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 opens with a specific verb and resource: 'Generate a fresh Ink (EVM) wallet' and adds 'a random secp256k1 keypair', making the tool's function unmistakable. It also clarifies the private key handling and chain, distinguishing it from any sibling tool.

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 provides a clear 'Ritual' sequence for the caller to follow after creating the wallet, which serves as usage guidance. It doesn't explicitly compare to alternatives, but none exist among the siblings, and the purpose is so specific that when-to-use is obvious.

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