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.
