nonce

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

The description includes pricing and API URL, which adds some transparency about cost and source, but does not disclose behavioral traits such as read/write nature, data freshness, or any side effects. No annotations are provided to compensate.

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 very concise, but the structure is minimal: it starts with a tag, then a Chinese phrase, then pricing. It is not well-organized and lacks key details, though it does not contain fluff.

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?

Despite having only two parameters, the description fails to explain what the tool does, what output it returns, or how it relates to blockchain nonces. The lack of an output schema and minimal description makes it incomplete for effective use.

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 the baseline is 3. The description does not add any extra meaning beyond the parameter descriptions already present in the input schema (address and chain).

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 only repeats the tool name as 'Nonce查询' with a [Blockchain] tag, lacking an explanation of what a nonce is or what the query returns. It does not differentiate from other blockchain query tools.

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 like address_txs or token_insight. There are no usage conditions, prerequisites, or exclusions.

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