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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does mention the data source (Blockscout) and the cost mechanism (x402), but it does not disclose whether this is a read-only network call, what the response shape is, whether there are rate limits, or whether the analysis is limited to a specific time range. The cost detail is useful but insufficient without broader behavioral context.

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 description is two sentences and every word contributes. It front-loads the main action and resource, then provides the data source and cost. There is no filler or unnecessary repetition.

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?

The description is adequate for a simple one-parameter tool, but it leaves some gaps. With no output schema or annotations, it does not explain exactly what the analysis result looks like, whether it returns structured categories, or how the 'counterparties' are presented. The cost and source details are welcome, but an agent still has to infer output semantics from the description.

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 coverage is 0%, but the single parameter 'wallet_address' is largely self-explanatory from its name and pattern. The description adds meaningful context by stating the wallet is on Base, which helps disambiguate the expected chain. However, it does not explain edge cases like checksummed addresses or whether only EOAs are supported, so the description only partially compensates for the missing schema descriptions.

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 ('Analyze'), a resource ('a Base wallet'), and the data domains ('balances, transfers and counterparties'), which is clear. It does not explicitly differentiate from sibling tools like base_wallet_profile or wallet_spy, though the mention of Blockscout and counterparties hints at a broader scope.

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 description gives no guidance on when to use this tool versus alternatives such as base_wallet_profile, base_transfer_search, or wallet_spy. It does not state what kind of analysis it is best for, nor does it mention exclusions or prerequisites beyond the wallet address.

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