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

No annotations are provided, so the description must disclose all behavioral traits. It only states that the tool reads positions, but lacks details on side effects, authentication requirements, rate limits, error handling, or data freshness. This is insufficient for a tool with no annotation support.

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 10-word sentence, making it very concise and front-loaded. However, it omits critical behavioral and usage details that could be included without sacrificing conciseness, such as the return structure or differentiation hints.

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 read tool with one optional parameter and no annotations or output schema, the description covers the core purpose but lacks completeness in terms of explaining the output, error states, or context for use. It is minimally adequate but leaves gaps for an AI agent.

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% description coverage for the only parameter (wallet_id), and the schema description already explains its conditional requirement. The tool description adds no further parameter semantics beyond what the schema provides, which meets the baseline expectation.

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 tool retrieves DeFi lending positions including health factor and USD amounts. The verb 'get' and resource 'DeFi positions' are specific, but the tool is not explicitly differentiated from siblings like waiaas_hl_get_positions, which could cause confusion.

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 provides no guidance on when to use this tool versus alternative positions tools from different protocols (e.g., Hyperliquid, Prediction Markets). There is no mention of prerequisites, when not to use, or context for choosing this tool.

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