Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter read-only status tool with no output schema, the description gives a reasonable overview of the return content (app/project/preset status, dirty keys, slice validity, running state). However, it does not describe the return structure or provide any usage context, such as when a status might be stale or what 'dirty keys' means. Given its simplicity, it is mostly complete but leaves some nuances unexplained.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
