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

With no annotations present, the description carries the full burden and does substantial work: it names the billable cost ($0.01 USDC on Base via x402, which affects whether an agent should call it), discloses the data provenance and cutoff (own launch records since 2026-10-23), and states the filtering policy (exchanges, bridges and busy services flagged, never linked). This goes well beyond a bare 'looks up a deployer' statement.

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 opening question frames the intent quickly, followed by a dense but information-bearing sentence and a short cost/disclaimer closer. Almost every clause contributes (chains, filtering policy, data cutoff, price), though the run-on middle sentence packs several distinct facts into one breath and the 'Not advice' disclaimer is marginal.

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 multi-chain enrichment tool with no annotations and no output schema, the description supplies the return shape, data freshness, filtering rules, and payment requirement. Remaining gaps are minor: error behavior when no funder is found, and any pagination or size limits on the returned token/deployer lists.

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 both parameters and the chain enum are already documented, including the base58/default-chain behavior. The description corroborates by listing the six supported chains and noting that a token address triggers a deployer lookup, but adds little that the schema does not already say. Baseline 3 is appropriate.

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 concretely states what the tool returns: the wallet that first funded the deployer, the other deployers that wallet funded, their tokens, and how many lost liquidity within a week. That is a specific resource and output, not a restatement of the name. It never mentions the sibling deployer_record, so an agent cannot tell from the text alone which of the two to call.

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 implied by the investigative framing ('serial ruggers launch each token from a fresh wallet funded from one source') and by stating that either a deployer wallet or a token address may be passed. However, no when-not conditions or named alternatives (deployer_record, token_risk_check, token_verdict) are given, so the routing decision is left to inference.

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