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

Annotations only cover readOnlyHint and openWorldHint; the description goes well beyond them by disclosing a hard rate limit (3 calls per caller per day), the absence of payment/wallet requirements, and the exact scope of the analysis performed (simulation, tax, mint, blacklist, pause, owner, liquidity). This is behaviorally rich and consistent with readOnlyHint=true since it is an inspection-style trial.

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-loads the value proposition and the free/rate-limit terms before the mechanics and the cross-sell. It is dense and parenthetical-heavy, but nearly every clause carries information; only minor tightening is possible.

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 2-parameter inspection tool with no output schema, the description covers what is checked, the cost model, the rate limit, and the follow-up tool, which is everything an agent needs to select and call 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%, so both parameters (token, simulate) are already documented in the schema. The description adds only 'Input: token address' and says nothing about the simulate flag, so it does not meaningfully extend schema semantics. 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 uses a specific question framing ('is this Base token safe to buy, or a honeypot, rug pull or scam?') and enumerates the checks performed (buy/sell simulation, tax, mint, blacklist, pause powers, owner, liquidity). It explicitly names the sibling it mirrors (base_token_risk) and how it differs (free trial), so an agent can distinguish it from the paid version without opening either schema.

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?

Explicitly states when to use it (free, no wallet or payment needed, 3 calls per caller per day) and names the alternative for continued use ('After the trial, use base_token_risk ($0.01 via x402)'). Both the condition and the successor tool are spelled out.

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