Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple mutating tool with one parameter and a clear purpose, the description is almost adequate. However, with no annotations, no output schema, and no parameter documentation, it falls slightly short—it might benefit from noting error conditions (e.g., task not found or already incomplete) or the reverse relationship to weeek_complete_task. Still, the minimal footprint makes this close to sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
