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

Beyond readOnlyHint and openWorldHint, the description discloses a $0.01 USDC cost, the exact payTo address, the external data sources used, and limitations such as 'not a full audit.' The word 'Paid' at the start is slightly ambiguous about whether the tool itself transfers funds, but the payment requirement is still materially transparent.

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 description is compact and front-loads the most unusual fact (the payment), then states purpose, parameters, and limitations. Every sentence carries relevant information with no filler, though the opening phrase could be reordered for clarity.

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?

Given only two parameters, no output schema, and annotations already covering safety, the description provides enough to select and invoke the tool correctly: address, chain options, default, payment details, and source. The exact return shape is not specified, but 'token security snapshot' plus the named data sources gives reasonable expectations.

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 the schema already documents address and chain well. The description mostly restates the format and default chain, adding little beyond what structured parameter descriptions already provide. This meets the baseline but does not add extra semantic value.

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 clearly identifies a token security snapshot produced via public honeypot.is and DexScreener, which distinguishes it from generic token/price lookups. However, it lacks an explicit verb like 'returns' and does not directly contrast with sibling tools such as token or dex, so it stops just short of a 5.

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?

It gives concrete invocation requirements: a 0x address is required, chain can be base/eth/bsc with base as default, and the call is paid. It also sets expectations by saying this is not a full audit and not investment advice. It does not name alternative tools for when a fuller audit is needed, but the context is still clear.

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