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 substantive behavior — the specific checks run (registry canonical-asset verification, freeze/clawback flags, trustline breadth, counterparty trust tier) and the cost ($0.02), which is genuinely useful. It still omits what the screen returns, whether a failure blocks settlement, and latency/rate behavior.

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?

A single front-loaded sentence that leads with cost and purpose, and the bulk of the content (registry examples, chain-specific issuers, check list) earns its place. It loses a point for the run-on parenthetical and the 'FLAGSHIP' marketing qualifier, which is pure noise.

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 annotations, no output schema, five optional parameters, and no required fields, the description should clarify how chain/token/address/currency interoperate (e.g., currency applies only to chain=xrp) and whether any parameter combination is mandatory. It gestures at the domain but leaves the invocation contract under-specified.

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 80%, so the schema already documents token alias, address format, currency, and counterparty. The description's registry examples (btsla/bcspx/bnvda…, rlusd, gatehub-usd, bitstamp-usd/eur) reinforce the token/address values but add little syntax or selection logic beyond the schema. 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?

States a specific verb+resource: a pre-trade 'settle-safe screen' that performs canonical-asset registry checks, freeze/clawback flag detection, and trustline breadth analysis on tokenized equities/RWAs. Sibling differentiation is weak, however — it never says how it differs from token_verdict or wallet_screen, even though 'optional counterparty wallet trust tier' visibly overlaps with wallet_screen.

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 phrase 'pre-trade settle-safe screen for AI agents trading tokenized equities/RWAs' implies the usage context (run before settling a trade), so the when is inferable. But there is no explicit when-not, no prerequisite chain selection guidance, and no named alternative for the overlapping sibling tools.

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