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

With no annotations, the description carries the full burden and does well: it discloses price ($0.0200 USDC per call), the payment protocol (x402), the transport (POST endpoint), and that data is live. It does not cover failure modes, rate limits, or what happens when the wallet does not exist, which keeps it from 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?

The capability statement is front-loaded in one dense sentence, then the use case, then commercial/transport metadata after a separator. No filler, and the ordering puts the most decision-relevant information first.

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?

For a one-parameter tool with no output schema, the description enumerates the returned fields, the cost, and the invocation protocol, which is nearly everything an agent needs. Remaining gaps (error behavior, response shape specifics) are minor.

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 100% and the single parameter is already documented as a base58 Solana address. The description only restates the input name ('dompet') and adds no format, constraints, or validation detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb and resource (check a Solana wallet) and enumerates exactly what is inspected: existence, SOL balance, account type, owner program, activity count/timing, plus risk warnings. This is clearly distinguishable from siblings like harga, risiko, or tokens-baru, which cover price, generic risk, and token discovery.

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?

Gives an explicit use context – bots verifying a user before a transaction – which tells the agent when this tool fits. It stops short of naming alternatives or stating when not to use it, so it is clear context without exclusions.

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