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

With no annotations, the description carries full burden and does disclose meaningful traits: the GeckoTerminal data source, the automatic risk flags, and that the call is metered (x402 $0.02/call USDC on eip155:8453). It omits rate limits, payment flow mechanics, and error/empty-result behavior, so it is good but not exhaustive.

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?

Purpose is front-loaded, followed by return contents, data source, usage, and price — a logical order with no filler sentences. Marked down slightly because the usage sentence is grammatically broken ('needs to fresh DEX launches') and partly restates the opening scope.

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 paid multi-chain scan tool with no annotations and no output schema, the description carries most of what an agent needs: what is returned, where the data comes from, and the cost. It does not explain pagination against the 'limit' param or what happens when no pools meet the filters.

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%, so all four parameters (network enum, minLiquidityUsd, maxAgeHours, limit) are already documented in the schema. The description only restates the liquidity/age filtering concept and the network list, adding no syntax, units, or defaults beyond what the schema provides — the baseline 3.

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+resource ('Scan newly created DEX pools') across named chains, and scopes it with liquidity/age filters. The 'newly created pool' framing implicitly separates it from crypto_yield_pools, but no sibling is ever named, so the differentiation is left to inference.

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?

Explicitly says 'Use this when an agent needs to [scan] fresh DEX launches with liquidity, volume and risk flags,' giving clear usage context. However, it names no alternative or exclusion (e.g. how it differs from crypto_yield_pools or crypto_price), so the routing guidance stops short of a 5.

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