Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no annotations and no output schema, the description needs to cover what happens when the tool is invoked, but it only names the action. An agent is left without knowledge of the tool's return value, side effects, or how the operation relates to flutter_hot_reload and flutter_kill, making it incomplete for a 1-parameter tool operating on a running app.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
