get_index_info

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

With no annotations provided, the description carries full burden for behavioral disclosure. It does not explicitly state that the operation is read-only, mention any authentication requirements, or describe what happens during the call. This lack of transparency is a significant gap for a tool that provides detailed information.

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 concise at one sentence with the verb and resource front-loaded. It is efficient but could add more value without being overly verbose, such as mentioning the purpose or output format.

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 presence of two siblings, the simple description may not provide enough context for an agent to distinguish when to use this tool. It does not describe the return values (no output schema) or any prerequisites, which is insufficient for a tool with no parameters and no annotations.

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 tool has zero parameters, so the baseline for this dimension is 4. The description does not need to add parameter information since there are none, and the schema coverage is 100% by definition.

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 'LlamaCloud index', and specifies the scope 'detailed information and its current status'. It effectively distinguishes from siblings 'query_rag' and 'search_documents' which focus on different operations.

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 description implies the tool is for retrieving index information and status but does not provide explicit guidance on when to use it versus siblings, nor does it mention when not to use it. Alternatives are not named, leaving the agent to infer based on tool names.

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