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

The annotations already establish read-only, idempotent, open-world, non-destructive behavior. The description adds useful context beyond annotations: the $0.05 cost, a free sample URL, 70+ chain coverage, and the pass/warn/fail rule that unknown is never a pass.

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 front-loaded with the core value proposition and then lists the returned evidence categories efficiently. It is somewhat long, but the enumeration earns its place for a broad dossier tool.

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 carries the burden of explaining return content, and it enumerates the major dossier sections plus the verdict checklist. It is nearly complete, though it does not describe response structure or error behavior.

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%, with both mint and optional chain clearly documented in the input schema. The description reinforces that the mint can be on any of 70+ chains but does not add syntax or selection details beyond the 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?

The description states a specific resource and scope: a complete dossier for one coin across 70+ chains in a single call. It enumerates the included evidence categories, making it distinguishable from narrower sibling token tools such as check_token_security or get_token_snapshot.

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?

Usage is implied by the comprehensive single-call framing and the $0.05 cost note, but the description does not explicitly say when to choose this over sibling tools or when a narrower check is preferable. No exclusions or alternative-routing guidance are given.

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