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

With no annotations, the description carries the full behavioral burden. It discloses the read-only public RPC nature, heuristic (not definitive) methodology, simulated sell/buy transfers with tax measurement, a financial-advice disclaimer, and a $0.005 x402 cost. It omits rate limits, failure modes, and payment/auth flow details, so it is strong 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?

The definition is front-loaded with purpose, then a dense list of checks, then concise behavioral notes. Every phrase—checks, read-only RPC, disclaimer, price—earns its place, with no redundant or filler text.

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?

No annotations, no output schema, and 0% schema description coverage mean the description must carry full context. It thoroughly explains what the tool checks and how it operates, but omits parameter semantics and any indication of return shape, leaving meaningful gaps for a complex paid risk 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% for two parameters. The description contextualizes the token as a 'Base ERC-20,' but never names or explains the token or chain parameters, their formats, or the chain default. It adds minimal meaning beyond the schema's enum and pattern constraints.

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 states a specific verb ('Heuristic risk checks') and resource ('Base ERC-20'), and enumerates the exact checks performed (contract code, metadata, proxy, selectors, pool, simulated transfers). It is immediately distinguishable from all sibling utility tools, none of which perform token risk analysis.

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 purpose—evaluate risk for a Base ERC-20—but the description gives no explicit when-to-use, when-not-to-use, or alternative-tool guidance. The sibling list contains no comparable risk tools, so routing ambiguity is low, but the definition still leaves invocation criteria to inference.

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