Web agents need safety rules and memory to work well
Browserbase says a browser agent can fail when it is simply sent onto the open web. A harness helps it handle logins, repeated steps, unsafe page text, and large amounts of information. For hermes-agent.nousresearch.com, the practical lesson is to save clear instructions and avoid exposing private login details.

- A harness is the set of rules, tools, memory, and safety checks around the agent.
