Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple with only one parameter, the description lacks essential behavioral context. It does not explain the impact of switching focus, prerequisites (e.g., an existing workspace), or any interaction with the broader terminal/session context. For a state-changing tool, this is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
