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

No annotations are provided, so the description carries the full burden. It does add genuinely useful non-schema context — the per-call cost of $0.01 USDC and the shape of the return payload — but it omits how many traders are returned, what 'most active and profitable' ranking means, and any rate or auth constraints.

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?

Three short sentences, front-loaded with the action and resource, then the return payload, then the pricing caveat. No filler or repetition; every sentence carries information the agent needs.

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?

There is no output schema, and the description compensates by summarizing the returned fields, including units (PnL in SOL) and cost. Minor gaps remain around result count and ranking methodology, but nothing blocks a correct invocation.

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?

Single parameter with 100% schema description coverage ('Solana token mint address (base58)'), so the schema already fully documents it. The description adds only the indirect phrase 'of a specific token', which does not go beyond the schema, so the baseline of 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?

States a specific verb and resource: 'Find the most active and profitable traders of a specific token', and enumerates what it returns (wallet addresses, volumes, PnL, trader type). This distinguishes it reasonably from holder-listing siblings like token_holders or wallet_pnl, though no sibling is named.

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 'traders of a specific token' — an agent can infer it is for per-token trader analysis. However, there is no explicit when-to-use vs. when-not, and no naming of alternatives such as smart_money, token_holders, or wallet_pnl that could serve overlapping needs.

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