vechainstats_get_account_daily_stats

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 does not mention any constraints (e.g., date must be historical), the effect of the 'expanded' parameter, or the shape of the response. As a read tool it likely doesn't have side effects, but the description provides no details beyond the basic action.

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 is front-loaded with the action and resource. The trailing 'etc.' is slightly vague but the overall structure is efficient. Every word earns its place, though more precision could be added without bloat.

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?

With no output schema and no annotations, the description should explain what data is returned, any date range limitations, and how 'expanded' changes the response. It does none of that. For a data-returning tool with these gaps, the description is incomplete.

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 100%, so both 'date' and 'expanded' are already documented in the schema. The description adds example stats (new accounts, active accounts) but does not add any parameter-specific meaning beyond what the schema provides. Baseline 3 is appropriate.

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 'Get daily statistics for accounts' with examples of the statistics (new accounts, active accounts). This is a specific verb+resource, but it doesn't explicitly differentiate from sibling tools like vechainstats_get_block_daily_stats or vechainstats_get_network_stats, though the name 'account' provides some distinction.

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. There are no explicit when-to-use or when-not-to-use statements, and no mention of alternatives. The description simply states what it does, leaving the agent to infer usage context.

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