rustchain_stats

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates this is a read operation ('Get') and specifies the return content, but it lacks details on permissions, rate limits, or error conditions. The description doesn't contradict annotations, but it's minimal for a tool with no annotation coverage.

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 highly concise and well-structured, using two sentences that efficiently state the purpose and key return metrics. Every sentence earns its place without redundancy, and it's front-loaded with the core functionality.

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 complexity (read-only stats retrieval), no annotations, 0 parameters, and the presence of an output schema, the description is reasonably complete. It outlines the return content sufficiently, and the output schema will handle detailed return values, though it could benefit from more behavioral context like data freshness or limitations.

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 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the return values, which aligns with the baseline for zero-parameter tools. It adds value by hinting at the output structure.

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 a specific verb ('Get') and resource ('RustChain network statistics'), and it distinguishes itself from sibling tools like rustchain_balance, rustchain_epoch, and rustchain_health by focusing on comprehensive system-wide stats. However, it doesn't explicitly differentiate from rustchain_miners or rustchain_health in terms of scope overlap, which prevents a perfect score.

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 when to prefer rustchain_stats over rustchain_epoch for epoch info, rustchain_health for health metrics, or rustchain_miners for miner details, nor does it specify any prerequisites or exclusions for usage.

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