xrpl_telemetry_settlement_series

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It usefully adds 'Newest first, UTC-aligned' and 'Free', but does not mention read-only status, pagination, or error behavior. It provides some context but is not exhaustive.

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?

Two sentences, front-loaded with 'Free' and the core purpose. Every clause adds value: granularity, metrics, ordering, timezone, and intended use. No redundant language or filler.

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 description provides enough context for a simple, two-parameter data retrieval tool, including the data points returned (USD totals, payment counts, XRP drops, RLUSD) and ordering. The absence of an output schema is partially compensated by these details. It does not explain the exact return structure, but that is not critical for this simple tool.

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%, with both 'count' and 'bucket' having meaningful descriptions. The description's mention of 'daily / weekly / monthly' and 'per bucket' adds minimal extra meaning beyond the schema, so the baseline of 3 applies.

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 identifies the tool as a bucketed time-series of XRPL settlement volume, specifying granularities and included metrics. It lacks an explicit verb like 'fetch' or 'return', but the noun phrase is unambiguous and distinct from sibling tools such as settlement_totals.

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 states 'For charting or change-point detection,' which gives a clear use case. However, it does not explicitly mention alternatives or when not to use this tool, relying on the sibling tool names to imply differentiation.

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