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

With no annotations provided, the description carries the full burden and does well: it discloses the paid model ($0.02 via x402, USDC on Base) and the upstream data source (DexScreener). It does not cover failure modes for unknown/non-Base addresses or any rate limits, leaving a modest gap.

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 tightly packed sentences with zero filler; every clause (cost, chain, grade scale, factor list, data source, use case) is load-bearing. Slightly dense with stacked parentheticals, but front-loaded and structurally sound.

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 output schema exists, yet the description explains the return shape (grade plus reasons), the data provenance, and the payment cost — everything an agent needs to call and interpret the result correctly for a single-parameter 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?

Only one parameter and schema coverage is 100%, so the schema already documents the address format ('Base token contract address 0x...'). The description adds no syntax detail beyond confirming the token must be a Base token, which is a marginal but real constraint. Baseline for a single fully-documented param is 4.

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 names a specific verb+resource (onchain safety verdict for a Base token) and enumerates the actual output (GREEN/MID/YELLOW/RED grade) plus the exact inputs it derives from (liquidity, pair age, turnover, buy/sell flow, volatility). This clearly distinguishes it from siblings like get_wallet_profile or score_repo_trust.

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?

"Screen tokens before interacting" gives a concrete when-to-use directive. There is no sibling offering a token safety verdict, so no explicit alternative needs naming, but no exclusion or boundary conditions are stated either.

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