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

Annotations indicate readOnlyHint=true, suggesting a safe read operation, which aligns with the description's 'get' action. However, the description adds minimal context beyond this—it doesn't disclose security implications (e.g., private keys are sensitive), rate limits, or what the output entails (e.g., plaintext key, encrypted data). With annotations covering basic safety, it earns a baseline score but lacks depth.

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 a single sentence that repeats the name/title, making it under-specified rather than concise. It wastes space on redundant information (e.g., the URL) without adding useful context. A more effective description would front-load critical details like security warnings or usage context.

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 tool handling sensitive private keys with no output schema and minimal annotations, the description is inadequate. It doesn't explain return values (e.g., key format, encryption), error conditions, or security risks. Given the high-stakes nature of private key access, more completeness is needed to guide safe usage.

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?

The input schema has 100% description coverage, with the parameter 'solanaWalletAddress' clearly documented. The description doesn't add any parameter-specific details (e.g., why this address is needed, format constraints beyond the schema). Since the schema does the heavy lifting, the baseline score of 3 is appropriate, but no extra value is provided.

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?

Tautological: description restates name/title.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., authentication, wallet setup), use cases (e.g., backup, recovery), or exclusions (e.g., not for public wallets). Given siblings like 'get_wallet_info', the description fails to clarify why one would choose this tool over others.

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