# 08 Compress

Script: `example/08_compress.py`.

`flow.Compressor` runs `run_session_compress(...)` to replace a long transcript with a smaller summary session.

```bash
python example/08_compress.py
```

| Step | Behavior |
| --- | --- |
| Build history | Run an agent turn to create assistant chunks. |
| Count rows | Inspect `len(session.chunk_table.rows)`. |
| Compress | Call `compressor.forward(session)`. |
| Continue | Use the compressed session as the next user-side context. |

Compression disables tools and expects the model to return text only.
