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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful disclosure of what is returned (price, curve, raised amounts, creator, launch origin), but with no output schema it omits any mention of error behavior for an unknown address or data freshness.

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?

A single front-loaded sentence opening with 'One coin:' then listing the payload. Dense and essentially waste-free, though it reads as a sprawling fragment rather than a structured statement.

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 must carry the return-value burden, and it does list the main fields. However, the ambiguity of the address parameter and the absence of any behavioral notes leave the definition only minimally sufficient for the call.

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% and the single required parameter 'address' is never referenced in the description. It is unclear whether this is a token contract address, a launch address, or a chain-qualified identifier, so the description fails to compensate for the coverage gap.

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 frames a single-entity lookup and enumerates the returned content: price, curve per paired market, amount raised, creator, and launch origin. It contrasts implicitly with the plural list_coins sibling via 'One coin'. It stops short of an explicit verb, but the resource and scope are 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?

There is no when-to-use guidance, no prerequisites (e.g. needing a known address), and no named alternative. An agent must infer that this is the address-keyed variant versus list_coins or list_markets entirely on its own.

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