xrp_validate_address

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

With no annotations, the description must disclose behavioral traits itself. It indicates a read-only format check but does not mention return values, error handling, or whether it operates offline. This is a significant gap for an agent deciding whether to use the tool and how to interpret results.

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 a single, clear sentence with no unnecessary words. It is front-loaded with the action and resource, making it maximally concise while still conveying the core function.

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 (one parameter, no output schema), but the description lacks information about the return value or behavior for invalid addresses. While the purpose is clear and the schema fully documents the parameter, the missing output semantics could hinder an agent's ability to use the tool correctly.

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 provides 100% coverage for the single parameter, giving a clear description ('XRP address to validate'). The tool description adds no extra meaning beyond what the parameter description already implies, so the baseline of 3 is appropriate since the schema does the heavy lifting.

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 a specific action (Validate) and resource (XRP address format), distinguishing it from sibling tools like bitcoin_validate_address or ton_validate_address. However, it does not elaborate on what validation entails (e.g., checksum, syntax, or network existence), leaving some ambiguity about the exact scope.

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 purpose is implied: use this tool when you need to verify an XRP address format. However, there is no explicit context, exclusions, or comparison to alternatives such as get_balance or chain-specific validators. The description provides no guidance on when not to use it.

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