circle_wallet_create

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

No annotations are provided, so the description must cover behavioral traits. It states the return value (wallet ID and address), which is good, but it does not disclose whether the operation is idempotent, irreversible, requires any permissions, or has side effects on existing resources. The transparency is adequate but not thorough.

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 extremely concise with exactly two sentences. The first sentence immediately states the action and output, and the second provides a key usage recommendation. Every word earns its place with no 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?

Given the tool has only two parameters, no output schema, and no annotations, the description covers the essential information: what it does, what it returns, and a practical hint. It is missing details on error handling, idempotency, or limits, but for a creation tool with low complexity, it is reasonably complete.

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 input schema has 100% description coverage for both parameters. The description adds a practical tip for the 'type' parameter ('Start with type='dev'') and an example for 'name', but these do not significantly extend the semantic meaning beyond what the schema already provides. The baseline score of 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 description clearly states the action ('Create a new Circle agent wallet') and the output ('Returns the wallet ID and on-chain address'). This directly distinguishes it from sibling tools like 'circle_wallet_list' (list) or 'circle_transfer_usdc' (transfer), which serve different purposes.

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 advises to 'Start with type='dev' for testnet exploration', which is a helpful usage hint. However, it does not explicitly contrast this tool with alternatives, nor does it specify when to avoid using it (e.g., if a wallet already exists). The guidance is present but limited.

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