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

Goes well beyond the readOnly/openWorld annotations: it discloses the data source (Fivebar's index of Uniswap v3/v4 pools on Robinhood Chain), the premium cost and free quota, required Bearer auth, and the heuristic that 100+ launches or 25+ in a day marks a launchpad relayer/bot rather than a person. It also frames output as 'facts, not a verdict,' which is valuable framing, though it doesn't discuss latency or failure modes.

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?

Front-loaded with the core promise and then progressively narrower detail, and the pricing/auth caveat is correctly placed at the end. It is dense — several clauses packed into single sentences — but almost every clause carries information an 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, so the description carries the return-value burden and does so thoroughly: launch count and timing, busiest day, current liquidity state per pool, whether the launcher still holds tokens, the funding wallet, and sibling launcher wallets. Nothing material an agent needs to interpret results is missing.

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% and already says the address is a token or wallet, so baseline is 3. The description adds real meaning by explaining that when a token is passed its launcher is resolved from the launch, which tells the agent how the single parameter is interpreted in two modes.

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 outcome — every token a wallet launched on Robinhood Chain and what's left of each now — and clarifies that the input can be either a token (whose launcher is derived) or the launcher wallet itself. This is clearly a launch-history tool, distinguishable from dev_check or bundle_check.

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?

Gives three concrete use-case phrasings ('has this dev launched before?', 'serial rugger?', 'what happened to their other tokens?') that map directly to agent intents. It stops short of naming a sibling alternative or stating when not to use it, so it is strong context without explicit exclusions.

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