There's no `--turbo` flag in mytool. `docs/cli.md` lists only these flags: - `--verbose` – extra logging - `--output PATH` – where to write results - `--dry-run` – show actions without doing them - `--retries N` – retry count (default 3) So there's nothing to enable. If you're looking to speed things up, the docs don't document any performance/parallelism option. You could check whether a newer version of mytool exists, or file a feature request — but as of the current docs, `--turbo` doesn't

If you saw it referenced somewhere, let me know where and I can dig further — or check `mytool --help` for anything undocumented.

Harness trace

Full harness trace — flagOn · seed 1

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
