Set up r0x wallet

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

With no annotations, the description must disclose behavioral traits itself. It mentions local generation, no payment, storage path, and reuse by other tools. However, it does not disclose what happens if the wallet already exists (overwrite behavior), whether import also requires payment, or security aspects of storing the private key—gaps that matter for a setup tool.

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 only two sentences long, front-loads the core purpose ('One-time setup'), and contains zero fluff. Every word adds value, making it highly efficient.

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 simplicity (2 params, no output schema), the description is nearly complete: it covers purpose, modes, storage, and reuse. The only missing piece is clarification of re-running behavior (whether it overwrites an existing wallet), which is relevant for a 'one-time' setup tool. This minor gap prevents a perfect 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 input schema already provides 100% description coverage for both parameters, including the enum for mode and the pattern for privateKey. The description adds the context of one-time setup and the 'no payment required to generate' note, but these are optional extras rather than essential semantic clarifications, so the baseline 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 tool's purpose: one-time setup for the r0x plugin, with two specific modes (import or generate). It distinguishes from all sibling tools, which are transaction/query tools, by being the setup prerequisite.

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 implies when to use this tool via 'One-time setup' and 'reused by every other r0x tool,' indicating it should be run before other r0x operations. It also explains the two modes, but does not explicitly say when to choose one over the other or list any alternatives, so it stops short of a 5.

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