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

No annotations are provided, so the description carries the full burden. It does disclose the price ($0.05) and the breadth of returned analysis, which are genuine behavioral facts beyond the schema. However, it says nothing about auth requirements, latency, caching, or failure behavior for an invalid/unsupported address, leaving real gaps for a paid tool.

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?

Front-loaded with the price, then purpose, then the returned signal list in one dense sentence with no filler. The enumeration is long but each item is a distinct capability claim, so it earns its space.

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?

With no output schema and no annotations, the description usefully doubles as a return-value summary and states the cost, so an agent knows what it gets and what it pays. The remaining gap is behavioral (permissions, errors, rate limits), which is modest for a read-only screening call.

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 compensate. It names the three supported chains and clarifies that XRPL is selected with chain=xrp, which adds meaning beyond the bare enum, but it never explains the address parameter's two accepted formats (0x hex vs XRPL r-address) that the schema only encodes as a regex pattern.

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?

States a specific verb+resource ("Wallet trust screen for any wallet") and enumerates the delivered signals (balance, tx count, flows, counterparties, contract-interaction risk, trust tier), which is far more than the name alone conveys. It also scopes the supported chains. It stops short of naming which sibling it replaces (token_verdict, forensics_info), so sibling differentiation is left to inference.

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?

Usage is implied rather than stated: an agent can infer "screen a wallet for trustworthiness" and that XRPL wallets get extra coverage, but there is no explicit when-to-use/when-not-to-use and no comparison against the token-focused siblings. The "(chain=xrp)" hint is the only routing guidance offered.

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