Anthropic Product
Anthropic’s guide on effective harnesses is directly about long-running agent reliability—exactly where most systems fall apart. The key is not adding a thousand guardrails, but building a harness that keeps the agent oriented, recoverable, and stateful over time.
Pros
- +Focused on long-running agent failure modes
- +Reinforces minimal, effective harness patterns
Cons
- -You still need to implement the operational details in your environment
