aureon_get_auth_nonce

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

With no annotations provided, the description carries the full disclosure burden. It conveys that the call issues a nonce/message intended for EIP-191 signing and that it is optional in API-key flows, but says nothing about nonce lifetime/expiry, single-use semantics, or that the call is a safe read-like generation — meaningful behavioral gaps for an auth primitive.

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 tight sentence with the core action front-loaded and the optionality caveat appended. No filler or redundancy.

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?

For a one-parameter, no-output-schema auth helper, the description plus schema is nearly sufficient: it names the purpose and the EIP-191 signing context and flags the optional case. The omission of nonce lifecycle/expiry behavior is the only notable gap.

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?

There is a single required parameter (address) with 100% schema description coverage, so the schema already defines it and the baseline is 3. The description adds no format or constraint detail beyond what the schema provides.

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?

States a specific verb (Request) and resource (wallet auth nonce/message) and names the downstream protocol (EIP-191 signing), which lets an agent distinguish it from generic auth siblings like aureon_dev_login and aureon_verify_wallet. It stops short of explicitly contrasting itself with those siblings, so it is clear but not fully differentiated.

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 parenthetical 'optional — issued API keys usually skip this' gives a concrete when-not-to-use condition, which is useful routing guidance. It does not name the alternative flow (e.g., dev_login or create_api_key) to use instead, so it falls 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.
