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

Since no annotations are provided, the description carries the full burden. It discloses that the blockhash is 'finalized', which adds behavioral context about finality. However, it does not explicitly state read-only behavior, network implications, or any potential errors. For a simple getter, this is adequate but not rich.

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 concise sentence that clearly states the core function. It is front-loaded with the action and resource, with no unnecessary words or 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?

Given no output schema and no annotations, the description could benefit from mentioning the return format (e.g., a string blockhash) and the network parameter. It is minimal but sufficient for a simple getter, though the lack of parameter and output details leaves some gaps.

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 description coverage is 0%, so the description must compensate for parameter meaning. The description does not mention the 'network' parameter at all. The enum and default in the schema are self-explanatory, but the description adds no value in explaining how network affects the result.

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 action 'Get' and a specific resource 'finalized blockhash', with a qualifier that distinguishes it from sibling tools like get_recent_transactions or get_solana_balance. An agent can clearly identify what this tool does and how it differs from alternatives.

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. The description only states the function, with no mention of use cases (e.g., constructing transactions) or when not to use it. There is no reference to sibling tools or context for choosing this tool.

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