Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of reading an entire knowledge graph, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'entire' entails (e.g., all nodes/edges), potential size limitations, return format, or error conditions. For a tool with significant scope, more context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
