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

Annotations already cover safety profile (readOnly, idempotent, non-destructive, openWorld), so the description adds real context beyond them: the demo is free, it returns a full verdict plus honeypot simulation, and it is restricted to a fixed token set. It omits rate limits or any per-call constraints on the demo, which is the only gap.

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?

Two sentences, front-loaded with the free/limited scope, then the reason to use it. No filler, and the pricing contrast with the paid sibling is compressed into a single clause.

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, the description usefully signals what the return contains (full verdict + honeypot simulation) so the agent knows the response shape is identical to the paid tool. Complete for a one-param demo; a brief note on whether demo results are cached or rate-limited would close the last gap.

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 0%, so the description must compensate, and it does by enumerating the exact allowed values (USDC, WETH, DEGEN, AERO), which map directly onto the enum. It does not mention the DEGEN default, which is documented in the schema, so it adds meaningful but not exhaustive parameter context.

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 (token safety check) with an explicit scope limitation to four Base tokens, and explicitly positions itself as the free demo variant of token_safety_check. An agent can distinguish it from the paid sibling and from erc20_token_quick_scan without opening any 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?

Gives an explicit when-to-use: preview the exact output shape before paying $0.01 for other tokens, and names the alternative (token_safety_check) that applies outside the four-token set. The routing decision is fully determined by the description.

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