vechainstats_get_all_token_prices

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 only says 'Get prices' but does not disclose potential response size, pagination, rate limits, price freshness, or any side effects (though likely none). The lack of any detail about the returned data format or operational characteristics is a significant gap.

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, well-structured sentence that is immediately informative. It avoids filler words and clearly communicates the tool's purpose and differentiating feature ('in one call').

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?

This is a simple no-parameter tool, but without an output schema or annotations, the description should at least hint at what 'prices' means (e.g., currency, format, or whether it includes all known tokens). The description is minimally adequate but leaves out details that could affect an agent's expectations, such as potential large payload or price time reference.

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 zero parameters, and the schema description coverage is 100% (vacuously). The description does not need to add parameter semantics, and the baseline for a zero-parameter tool is 4. The description adds no extra parameter info, but none is needed.

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 verb ('Get'), the resource ('all VeChain tokens'), and the scope ('in one call'), which distinguishes it from the sibling tool vechainstats_get_token_price that presumably handles a single token. It is specific and unambiguous.

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 phrase 'all VeChain tokens in one call' strongly implies this is the batching alternative to the singular get_token_price, giving clear context for when to use it. However, it does not explicitly name the alternative or provide an exclusion condition, so it falls short of a 5.

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