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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds useful semantics: addresses are random, registered, and scid limits sampling to asset holders. The non-idempotentHint is consistent with 'random'. No contradiction with annotations.

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?

Well-structured with purpose, when-to-call, input requirements, and output shape. It is concise and easy to scan, though there is slight redundancy with the schema pattern and the implementation detail 'via DERO.GetRandomAddress' adds limited value.

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 simple read-only tool with one optional parameter, the description fully covers invocation context, parameter behavior, constraint, and output format. Strong annotations further reduce the need for additional safety or side-effect disclosure.

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 100% and already enforces the 64-hex pattern. The description adds meaning beyond the schema by explaining that providing scid 'limits sampling to holders of that asset,' which is the key behavioral effect of the parameter.

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 function: 'Get random registered addresses from the chain' for ring construction in private transfers. This specific verb+resource combination distinguishes it from sibling getters like dero_get_transaction or dero_get_block.

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?

Provides explicit 'When to call' guidance: building a transfer ring in external wallet tooling or sampling chain participants. It gives clear context but does not explicitly mention when not to use it or name alternative tools.

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