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

Annotations already declare readOnlyHint and openWorldHint, so the bar is lower; the description adds the genuinely useful billing context ('PAID $0.005 USDC') and enumerates what comes back (pool, DEX, token, quote, creation time, volume/liquidity since launch). It does not state refresh latency or the defaults used when hours/limit are omitted.

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?

Two sentences, front-loaded with the payment cost then the use case, ending in a compact payload list. There is no filler and the return-field list earns its place because no output schema exists.

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?

All parameters are optional, so an agent can call it with zero arguments, yet the description never says what the default window/limit or sort order is — a real gap for a zero-required-param tool. The payload description partly compensates for the absent output schema, making it minimum viable rather than complete.

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 only 25% — only api_key is documented, and that documentation lives in the schema, not the description. The description implies the chain enum ('BNB Chain or Base') and a launch window ('just launched'), but hours and limit are never explained: no default lookback, no sort order, no max limit. With low coverage the description should compensate and it largely does not.

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 resource (new DEX pools) with concrete scope: chains (BNB Chain, Base) and named DEXes (PancakeSwap/Uniswap/Aerodrome), plus the return payload. It is distinguishable from meme_trending/meme_history by the 'just launched / new pool' framing, though it never names those siblings explicitly as alternatives.

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?

'Use when an agent asks what tokens just launched or got a new pool' gives a clear triggering condition. No exclusions or sibling alternatives are named (e.g., how this differs from meme_trending or lookup_pool), so the routing is good but not complete.

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