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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the per-call cost and returned fields, and “Get” implies a read operation, but it does not state permissions, rate limits, or other operational constraints.

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 core purpose and followed by the cost. Every sentence adds useful information without waste.

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 simple one-parameter read tool without annotations or an output schema, the description adequately explains the returned profile contents and the per-call cost. It could be more complete by clarifying when to prefer it over sibling wallet tools, but the core call context is present.

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?

There is one required parameter, walletAddress, and schema description coverage is 100%; the schema already documents it as a Solana base58 address. The description adds no additional parameter meaning beyond the schema baseline.

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/resource (“Get a complete wallet profile”) and enumerates the returned data: SOL balance, token holdings with USD values, NFT count, and top holdings. It does not distinguish this from close siblings like wallet_balance or wallet_pnl, so sibling differentiation is missing.

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 explains what is returned and notes the $0.005 USDC cost, but gives no guidance on when to use this tool instead of wallet_balance, wallet_pnl, or related wallet tools. The agent must infer the appropriate use case.

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