+browser-harness is a thin layer that connects agents to browsers via an editable CDP harness.
+
+# Code priorities
+- Clarity
+- Precision
+- Low verbosity
+- Versatility
+
+# Overview
+Core code lives in `src/browser_harness/`:
+- `admin.py` — daemon lifecycle, diagnostics, updates, profile management
+- `daemon.py` — the long-lived middleman process between the browser and the agent
+- `helpers.py` — CDP wrapper and core browser primitives auto-imported into `-c` scripts
+- `run.py` — the `browser-harness` CLI
+
+`SKILL.md` tells agents how to use the harness and CLI.
+`install.md` tells agents how to install it, attach a browser, and troubleshoot.
+In this checkout, invoke the current source with `./browser-harness`; do not use
+a globally installed `browser-harness` binary.
+
+For recording or video tasks, follow `SKILL.md` and
+`interaction-skills/make-video.md`. A natural request to show, record, or demo
+the work opts in; significant work alone does not. Keep the exact path returned
+by `start_recording()` and never reenact a finished task.
+
+An agent operating the harness only edits inside `agent-workspace/`:
+- `agent_helpers.py` — task-specific browser helpers the agent adds
+- `domain-skills/` — skills the agent writes and reads
+
