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

With no annotations, the description carries the full burden and does so well: it names data sources (GoPlus, honeypot.is, DexScreener), states results are 'Live per request' (no caching), flags 'not financial advice', and fully explains the x402 pay-per-call cost, network, automatic payment challenge, and client retry 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?

The core purpose and outputs are front-loaded, and each clause (sources, disclaimer, payment flow) carries distinct information. It is a dense single paragraph rather than a run-on, though the payment/provenance clauses could be separated for faster scanning.

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?

There is no output schema, so the description must describe returns — and it enumerates every field the caller gets (score, grade, take, risk facts, card link). It also covers provenance, freshness, legal caveat, and the payment handshake, leaving nothing an agent needs in order to invoke it correctly.

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% and the single 'token' parameter is fully documented in the schema (0x + 40 hex format). The description only restates 'send a BSC token address', adding no syntax or format detail beyond the schema, so the baseline 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 states a precise verb+resource: send a BSC token address, receive a risk verdict (score, grade, plain-language take, risk facts, card link). The scope is specific enough that no sibling (bsc_alerts, event_facts, market_state, ping) could be confused with it, even without naming an alternative.

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?

'in one call' implies this is the one-stop risk check, suggesting when to reach for it over composing multiple sources. However, there is no explicit when-not, no named alternative, and no statement of prerequisites beyond the payment note. Usage is implied rather than directed.

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