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

Annotations already communicate that this is a non-read-only, idempotent, non-destructive operation. The description adds the 'free' aspect and network/currency context but does not disclose side effects such as wallet creation behavior, key management, or any rate limits. This is acceptable given annotation coverage, but not particularly rich.

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?

A single sentence that front-loads the verb and resource, then adds the key specifics (free, Base Mainnet, USDC). Every word contributes useful information, with no redundancy or 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 tool is simple and has an output schema, so return values do not need explanation. However, the only input parameter is undocumented and the description gives no details about what provisioning entails or how agent_name is used. This is a noticeable gap even for a one-parameter tool.

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 schema provides zero description for the only parameter, agent_name, and the description also fails to explain its meaning, expected format, or uniqueness. The parameter is somewhat inferable from the tool name and purpose, but the description does not compensate for the 0% schema coverage.

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 uses a specific verb ('Provision') and identifies the exact resource ('Blue Cap machine wallet') plus network and currency context ('Base Mainnet, USDC'). This clearly distinguishes it from the unrelated siblings like evidence_verify and hash_compute.

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 intended use case is clear: provision a wallet for an agent on Base Mainnet. There are no relevant alternatives among the sibling tools, so explicit exclusions are unnecessary. However, it does not explicitly state when not to use the tool or provide alternative routing.

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