get_daily_onchain_tx

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

No annotations are provided, so the description bears full responsibility. It only says 'get' implying a read operation, but does not disclose any behavioral traits such as latency, authentication needs, rate limits, or whether it returns data for a specific chain. The name suggests it's a read but lacks detail.

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, direct sentence with no extraneous information. Every word contributes to the purpose. It is appropriately sized for a tool with no parameters.

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 has no parameters and no output schema, the description is minimal. It provides the basic purpose but lacks details like which blockchain, timezone, or format of the data. For a simple retrieval, it is adequate but leaves room for interpretation. More context on the data source or return structure would improve completeness.

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?

There are no parameters (schema coverage 100%), so the description adds no burden. The simple statement is sufficient since no parameters need explanation. A baseline of 4 is appropriate because there is nothing to compensate for.

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 it retrieves daily on-chain transaction volume data ('获取每日链上交易量数据'). The verb 'get' and resource 'daily on-chain transactions' are specific. It distinguishes from siblings that focus on other metrics like stablecoin marketcap or exchange rankings, though it could be more explicit about the scope (e.g., total across all chains).

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 on when to use this tool versus alternatives. The description does not mention any prerequisites, expected context, or situations where another tool would be more appropriate. With no parameters, it may be automatically invoked, but still lacks usage direction.

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