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

Adds material context beyond the annotations: it explains the pricing model ($0.05/call via x402 USDC or card key, first 25 free, failed calls free), the failure semantics, and — crucially — why readOnlyHint=false despite read/compute-only behavior (each call is charged). That directly resolves the most confusing annotation signal an agent would see.

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 composition and return contents, then limits, then pricing. Dense but each clause carries signal; the final sentence slightly restates the read-only point already implied by the prior sentence, a minor overlap rather than waste.

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 only two simple parameters, the description adequately previews what comes back (risk tiers, flags, market data, nonce, native balance) and bounds what it does not cover. An agent has everything needed to decide and invoke 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 description coverage is 100%, so both parameters are already documented as 0x-prefixed 20-byte Base addresses. The description adds no format, constraint, or validation detail beyond the schema, which lands this at the baseline for a fully-documented schema.

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: it combines Base token-report risk tier/flags, DEX market data, and wallet-audit risk tier/flags/nonce/native balance into one sourced indicator set. This aggregation is distinguishable from the sibling token_report, wallet_audit, and contract_risk tools, and the itemized return contents make the scope unambiguous.

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?

"Use as one input before a Base trade" gives clear context, and the explicit exclusions (no buy/sell recommendations, no calibrated confidence, no holder concentration) tell the agent what this tool will not answer. It stops short of naming which sibling to prefer for those excluded needs, but the boundary is clear.

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