Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a recording-splitting operation, no annotations, and no output schema, the description is insufficient. It doesn't explain the outcome (e.g., file naming, recording continuity) or error conditions, leaving the agent with incomplete context for reliable use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
