## Result window

Every local MCP tool accepts `resultStart` and `resultEnd` so large payloads can be paged.

- `resultStart` — first character offset. Default `0`.
- `resultEnd` — exclusive end offset. Default `8000`.
- `resultEnd - resultStart` must be at most **8000** characters.
- Increment `resultStart` by 8000 to read the next window.
