spraay_xrp_estimate

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

Annotations already indicate it is not read-only, not destructive, and not idempotent. The description adds behavioral transparency by disclosing that each call costs $0.001 USDC, which is valuable beyond the annotations. However, it does not detail other behavioral aspects like rate limits or side effects.

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 extremely concise, consisting of two short sentences. The first states the purpose, the second provides cost and usage instruction. No wasted words; every sentence earns its place.

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 existence of an output schema (not needed to explain return values), the description covers basic purpose and cost. However, it lacks specificity about what the estimate returns (e.g., cost in XRP or USDC) and does not clarify if this is a prerequisite for other actions like spraay_xrp_batch. Adequate for a simple tool but not exhaustive.

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% (one parameter, recipientCount, described in schema). The description adds no further meaning beyond the schema's minimal description; it only instructs to provide the listed fields. With high schema coverage, 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 'XRP batch estimate', which distinguishes it from sibling tools like spraay_xrp_batch and spraay_batch_estimate. It indicates the tool provides an estimate for XRP batch operations, though it could be more specific about what is estimated (cost? transactions?).

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 mentions a cost of $0.001 USDC per call, which warns about monetary cost. However, it does not provide guidance on when to use this tool versus alternatives like spraay_batch_estimate or spraay_xrp_batch, nor does it state prerequisites or avoidances.

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