defi_staking_apr

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

No annotations provided. The description does not disclose whether the tool is read-only, mutating, requires authentication, has rate limits, or any other behavioral traits. Pricing info is not about behavior.

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 poorly structured for AI: it starts with a label and URL rather than a clear purpose statement. It is not front-loaded with the most critical information.

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?

For a simple tool with one parameter and no output schema, the description lacks essential context: what the output format is, which protocols are supported, and how to interpret results. The parameter description is conflicting.

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 100% coverage, so baseline is 3. The description adds no extra meaning to the parameter 'protocol' beyond what the schema says. The schema itself has a contradiction (required but described as optional), but the description does not resolve it.

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 indicates the tool returns '质押APR' (staking APR) via the API URL, but lacks a clear verb like 'get' or 'fetch'. The resource is implied but not explicitly stated, making it somewhat vague. It also doesn't distinguish itself from similar siblings like 'defi_lending_rates'.

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 vs alternatives. No mention of prerequisites, typical use cases, or when not to use it. The agent receives no help in deciding between this and other DeFi tools.

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