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 states the tool retrieves information ('Get'), implying a read-only operation, but doesn't specify if it's safe, has rate limits, requires authentication, or details the response format. The description lacks behavioral traits beyond the basic action, leaving gaps in understanding how the tool behaves in practice.

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 extremely concise and front-loaded, using a single sentence that lists key data points without unnecessary words. Every part of the description earns its place by specifying what information is retrieved, making it efficient and easy to parse.

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 the tool's low complexity (0 parameters, no annotations) and the presence of an output schema, the description is minimally adequate. It covers the purpose but lacks behavioral context and usage guidelines. With an output schema handling return values, the description doesn't need to explain outputs, but it should provide more guidance on when to use it versus siblings to be fully complete.

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 tool has 0 parameters, and schema description coverage is 100%, so no parameter documentation is needed. The description doesn't add parameter information, which is appropriate here. A baseline score of 4 is applied as the description compensates adequately by focusing on the tool's purpose without redundant parameter details.

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 clearly states the tool's purpose with the verb 'Get' and specifies the resource 'blockchain info', listing specific data points like chain, difficulty, softfork statuses, chain work, and pruning. It distinguishes itself from siblings by focusing on general blockchain metadata rather than specific analyses or operations, though it doesn't explicitly contrast with similar tools like get_network_info or get_node_status.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context, or compare with sibling tools like get_network_info or get_node_status, which might overlap in functionality. Usage is implied only by the data points listed, with no explicit when/when-not instructions.

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