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

With no annotations provided, the description fully discloses behavior: it is read-only, flags blocklisted counterparties, surfaces notable transactions, and returns specific data including a pagination marker. It also mentions the price and a feedback channel. This exceeds the burden for transparency, clearly stating the tool's safety and functional traits.

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 long sentence followed by a short feedback note. It is dense with valuable information and front-loaded with the core purpose, but the length and run-on structure slightly reduce readability. Every sentence earns its place, though the first sentence could be more scannable.

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 covers purpose, return values (balance, summary, marker), risk features, price, and read-only nature. With no output schema, it reasonably explains outputs. However, it lacks details on error conditions, exact formatting of returned data, or how pagination actually works (e.g., using a recent call's marker as input), leaving minor ambiguity.

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 description coverage is 0%, so the description must explain the parameters. It mentions 'address' indirectly via 'wallet' and 'recent transactions' but does not clarify the 'limit' parameter or any pagination input. The marker is only described as a return value, not as an input for further paging. This leaves significant gaps for the two parameters.

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 purpose: providing a readable, risk-annotated history of an XRPL wallet's recent transactions. It lists specific features (plain-language amounts, trustlines, DEX/AMM ops, blocklist flags, notable account-takeover transactions) and distinguishes itself from sibling tools like check_address or check_alerts by focusing on comprehensive wallet activity monitoring.

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 implies a clear use case ('watching your OWN wallet is compromise detection') and notes it is read-only and priced. However, it doesn't explicitly contrast with sibling tools or state when not to use it, instead deferring unmet needs to submit_feedback. This provides context but lacks explicit exclusions or direct alternative comparisons.

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