create_wallet

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

With no annotations, the description carries full burden. It mentions 'create or pregenerate' but does not clarify side effects, permissions needed, or behavior if wallet already exists. No disclosure of destructive or read-only traits.

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 concise (two sentences) with no wasted words, but it lacks essential details. It is not overly verbose, but the brevity compromises informativeness.

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?

Despite having an output schema, the description does not cover parameter semantics or return value. For a 2-parameter tool, it should explain parameters and success/error states. Incomplete for effective use.

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 0%, yet the description adds no meaning to the parameters. 'user_id' is required but unexplained; 'chain_type' has a default but no allowed values or relation to 'supported chains' is made.

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 verb 'Create or pregenerate' and the resource 'wallet for a user', explicitly listing supported chains (Ethereum, Solana, Bitcoin, EVM-compatible). This distinguishes it from siblings like 'get_wallet' or 'update_wallet'.

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 guidance on when to use this tool versus alternatives like 'create_user' or 'get_wallet'. The description does not mention prerequisites, when not to use it, or how it relates to sibling tools.

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