What this means for you / your team

Treat Atlas-style agents as early-stage tools. Keep tasks narrow, require human supervision, and validate outputs.

Security

• Limit the agent’s credentials and scope; avoid broad access by default.
• Assume pages can contain hidden instructions; sandbox actions where possible.

Reliability

• Do not rely on summaries or actions without verification.
• Use as a productivity aid, not a replacement for due diligence.

Bottom line

Agent-enabled browsing is compelling—and raw. Proceed with guarded optimism: clear task boundaries, least-privilege access, and consistent human oversight.
