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 well: it discloses the execution model (bytecode evaluation plus simulated DEX trade), the dimensions measured (buy/sell tax percentages, blacklist restrictions), and the monetary cost (0.005 USDC on Base). It does not cover failure modes, latency, or what happens when a token cannot be simulated.

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 category label and the core capability, followed by the cost. No filler or redundant restatement of the name.

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 no annotations and no output schema, the description adequately supplies the return-value essence (sellability, tax percentages, blacklist flags) and the cost of invocation. The only gap is ambiguity between the Base-only wording and the presence of a chain_id parameter that hints at multi-chain support.

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 50%: token_address is documented in the schema, but chain_id has no description. The description partially compensates by repeatedly scoping the operation to Base, which maps to the chain_id default of 8453, but it never explains the parameter or whether other chains are supported.

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 and resource: evaluating ERC-20 bytecode and simulating DEX trade execution on Base to detect honeypots and tax levels. It is concrete about what is measured (buy/sell tax, blacklist restrictions), but it never references or distinguishes itself from the sibling safety tools analyze_liquidity and rugshield_pre_swap_scan.

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 only implied via the stated goal of verifying whether a token can be sold back to liquidity pools, which suggests a pre-trade check. There is no explicit when-to-use guidance, no exclusions, and no routing advice distinguishing it from the sibling scan tools.

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