+# agent-browser
+
+Browser automation CLI installed in the sandbox image. Driven by the agent
+through `exec_command` (not a function tool).
+
+- **Implementation:** sandbox CLI at
+  `/home/pentester/.npm-global/bin/agent-browser` — npm package
+  `agent-browser@0.26.0` (Vercel), driving Chromium directly.
+- **Strix config:** `containers/Dockerfile` sets `AGENT_BROWSER_*` env
+  (executable path, UA, launch args, screenshot dir).
+- **Skill:** `strix/skills/tooling/agent_browser.md` — **always-loaded**
+  into every agent prompt by `strix/agents/prompt.py:_resolve_skills`.
