Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's destructive nature, no annotations, no output schema, and 0% schema description coverage, the description is insufficient. It omits critical context: success/error responses, side effects (e.g., if archiving affects related data), idempotency, or authentication requirements. For a batch deletion tool, this leaves significant gaps for safe and effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
