libtmux_mcp.prompts.recipes.diagnose_failing_pane(pane_id: str) -> str
```

Gather pane context and propose a root-cause hypothesis.

Uses ``snapshot_pane`` (content + cursor + mode + scroll state
in one call) instead of ``capture_pane`` + ``get_pane_info`` so
the agent sees everything in a single protocol call. When the
diagnosis needs another read after waiting or observing, the
rendered recipe points agents at ``capture_since`` instead of a
repeated full capture.

## Parameters

- `pane_id` (str): The pane to diagnose.
