## 2026-08-15 — v0.1.8 runtime contract

Run Python through stdin; `-c` is no longer accepted:

```bash
browser-harness <<'PY'
print(page_info())
PY
```

Helpers are pre-imported and the daemon is ensured before execution. Task-specific helpers live at `$BH_AGENT_WORKSPACE/agent_helpers.py`; without an override the workspace is `~/.config/browser-harness/agent-workspace/`. Domain skills live below `$BH_AGENT_WORKSPACE/domain-skills/` and are disabled unless `BH_DOMAIN_SKILLS=1`.

Web work uses the browser from the first step; the root's First moves section owns the only plain-HTTP exception.
