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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds that it is a thin pass-through to a single endpoint returning that response verbatim, which is mildly useful. It says nothing further about pagination limits or truncation beyond what the schema already states.

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 endpoint mapping and scope come first, which is the right front-loading, and the whole thing is four short sentences. The closing marketing sentence about copy trading leaderboards is the weakest part and only loosely earns its place.

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?

An output schema exists and all eight parameters are documented, so the description need not explain returns; the annotations cover safety. The remaining gap is sibling disambiguation from get-token-top-pnl-traders, which the description leaves implicit.

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 all eight parameters including sortByAsc/sortByDesc, resolution and ilikeFilter are already documented. The description mentions ranking by PnL, win rate and volume, which loosely maps to the sort fields, but adds no syntax or interaction details (e.g. mutual exclusivity of sort directions) 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?

States a specific verb and resource ('Calls only GET /v4/wallets/top-traders') plus the ranking dimensions (PnL, win rate, volume), which makes the wallet-level scope recognizable. It does not name or contrast with the closest sibling, get-token-top-pnl-traders, so an agent must infer that this returns traders across the whole DEX rather than per-token.

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 only implied: 'Power copy trading leaderboards and smart money discovery tools' suggests the intended scenarios but gives no explicit when-to-use or when-not-to-use rules. There is no mention of how it differs from get-token-top-pnl-traders or list-labeled-accounts, both of which an agent could plausibly reach for.

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