Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (server-side move preserving metadata), the description covers all essential aspects: what it does, how it differs from alternatives, behavioral traits (auth, rate limit, error conditions), and it references an output schema (metadata + etag). It is complete for an AI agent to understand when and how to use it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
