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

With no annotations provided, the description carries the full burden. It discloses critical behavioral traits: the $0.01 via x402 payment requirement, liveness ('live'), and data source ('Live from Dexscreener'). It does not cover rate limits, error behavior, or response format, but the most important operational traits are present.

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 compact and front-loaded: it opens with the cost, then the data payload, scope, and source. Each sentence earns its place; the 'For crypto trading, sniping, and research agents' line is brief and useful for agent routing.

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?

For a two-parameter lookup with no output schema, the description covers the input type, expected output fields, scope, source, and cost. The main gap is the lack of clarity around how x_payment is supplied and what the raw response shape is, but overall the tool can be invoked correctly with the given information.

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 50%, and the description largely restates q's semantics ('symbol, name, or contract') while adding output-context. It does add some meaning to the payment flow by mentioning '$0.01 via x402', but it still leaves the x_payment parameter's exact value and requirement ambiguous.

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 names a specific resource: 'live decentralized-exchange data for any token (symbol, name, or contract)' and enumerates concrete outputs (USD price, 24h volume, liquidity, buy/sell counts, momentum). It clearly differentiates from siblings like chain_token_identity, crypto_prices, or token_launches_feed by emphasizing DEX-specific, cross-chain live data.

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?

The description gives a clear context for when to use the tool: 'For crypto trading, sniping, and research agents' and 'for any token ... across every chain.' It does not explicitly name alternatives or when-not conditions, so it falls short of a 5, but the use-case framing provides solid selection guidance.

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