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

With no annotations, the description carries the full burden and does well: it discloses the data sources (GoPlus and DexScreener), the enumerated verdict values (CLEAR/CAUTION/AVOID/UNKNOWN), the 10-minute cache with a bypass flag, and the paid x402 in-band payment flow on Base. The main blemish is an internal pricing inconsistency ('$0.01 safety verdict' vs '$0.02 USDC'), and it says nothing about rate limits or error 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 facts are front-loaded, which is good, but the bracketed tag line and the following sentence repeat the same 'token safety plus price ... trade check' phrasing almost verbatim. Payment and URL fallback details consume space disproportionate to their selection value.

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?

For a tool with no annotations and no output schema, the description usefully enumerates return fields and explains payment/caching, which covers most of what an agent needs. It remains incomplete on address format and per-chain expectations, and the conflicting $0.01/$0.02 figures leave cost ambiguous.

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 only 25%, so the description needs to compensate and largely does not. It clarifies only 'fresh' (cache bypass, with the ?fresh=1 convention) while leaving 'chain' (23-value enum) and 'address' (contract address vs symbol, per-chain format) unexplained, and only implies the pass parameter indirectly via the payment discussion.

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 uses a specific verb+resource framing ('Token safety plus price in one token brief and trade check') and enumerates the outputs (safety verdict, price, 24h change, volume, liquidity, FDV). An agent can tell it is a combined safety+market snapshot tool. It does not, however, explicitly differentiate itself from close siblings like get_token_verdict, get_token_verdict_deep, or get_brief_teaser.

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?

There is no explicit when-to-use/when-not guidance and no routing advice among the several token-verdict siblings. The only usage-adjacent hints are the '?fresh=1 skips the 10-minute cache' note and the pass parameter, which are mechanical rather than selection guidance.

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