search_docs

Read-only

Search DefiLlama SDK documentation to locate methods, parameters, and example code before writing execute() when unsure of the API.

Instructions

Search DefiLlama SDK docs to find the right methods, parameters, and example code. Use before writing execute() code when you're unsure of the API.

Behavior4/5

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

Annotations already declare readOnlyHint=true, so the description's mention of 'search' aligns. It adds value by specifying the kind of results (methods, parameters, example code) and the intended usage context, though it doesn't go into deeper behaviors like rate limits or output format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no redundancy. The first states the action, the second provides usage guidance, and every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a search tool with 2 parameters and no output schema, the description adequately covers purpose, usage, and output hint. The 'detail' parameter is not explained, which is a minor gap given its simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It gives meaning to the 'query' parameter as the search term but entirely omits the 'detail' parameter. Partial compensation only.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it searches DefiLlama SDK docs for methods, parameters, and example code, using the specific verb 'search' and resource 'docs.' It distinguishes from the sibling 'execute' tool by framing this as a pre-execution lookup.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says to use before writing execute() code when unsure of the API, providing both a clear context and an implicit alternative (execute). This is strong when-to-use guidance.

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