Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (one parameter, no output schema, no nested objects), the description covers the core purpose and idempotency. However, it omits prerequisites (e.g., pipeline must exist and be active), which are important for correct usage. The presence of resume_pipeline among siblings implies reversibility, but this is not stated.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
