What is the harness
Harness is the structure that surrounds the model: permanent instructions, action limits, automatic checks, stopping criteria, and mandatory response format. It is this layer that transforms capability into predictable behavior.
Essential components
- Permanent instructions with defined scope and tone.
- Explicit access limits to files, network, and credentials.
- Output verification before considering the task complete.
- Stopping and escalation criteria to a person.
- Log of what was executed.
Why demos deceive
In a demo, the path is known. In a real operation, incomplete inputs, integrations being down, and ambiguous requests appear. Without a harness, the agent improvises. With a harness, it stops and warns.
Frequently Asked Questions
Harness substitui revisão humana?
Não. Ele define onde a revisão humana é obrigatória e garante que o agente não avance sem ela em ações sensíveis.
