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

With no annotations, the description carries the burden and does well: it discloses the 2-hop trace limit, the returned categories (shared-funder clusters, dev-linked wallets, fresh wallets, holdings, coordination-risk %), and the $0.02 x402/USDC pricing. It omits auth/payment failure behavior and rate limits, so not a 5.

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 question, then the analysis method, outputs, and price — every clause earns its place. The single dense paragraph is slightly run-on compared to a structured breakdown, but there is no filler.

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?

Given zero annotations, no output schema, and 0% param coverage, the description is complete on purpose, outputs, hop limit, and pricing but leaves parameter behavior and payment-failure semantics unexplained. Adequate, with clear remaining gaps for a paid 3-param tool.

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 0%, so the description must explain all three params. It hints at depth ('up to 2 hops') but never ties that to the depth parameter or its range; it says nothing about what 'buyers' controls (how many early buyers are sampled) or what format 'token' expects (mint address vs. symbol).

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?

A specific verb (trace) applied to a specific resource (early memecoin buyers' funding) on a specific chain/venue (Solana pump.fun), framed around a concrete question: independent buyers vs. one operator. That analysis is distinct from siblings like memecoin_token_report or memecoin_exit_check, so an agent can route without opening schemas.

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 opening question implies the use case (bundle/insider due-diligence before trading), and the list of outputs signals what decisions it supports. However, it never states when to prefer this over memecoin_exit_check, memecoin_pretrade_check, or crypto_address_risk, nor any exclusion; guidance remains implied rather than explicit.

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