Loop Engineering stack
A clean layered diagram showing Prompt Engineering, Context Engineering, Harness Engineering, and Loop Engineering as a recurring system contract.
Loop Engineering Stack
From single prompts to recurring, stateful, verified agent systems
Prompt Engineering
What should I say to the model?
Context Engineering
What state, memory, docs, and examples should the agent see?
Harness Engineering
What tools, permissions, sandboxes, traces, and checks surround one agent run?
Loop Engineering
A recurring system contract for agent work.
1. Goal + Trigger
Define success, cadence, and work intake.
2. Context + Harness
Load state, tools, permissions, and isolation.
3. Delegate + Verify
Route work, test, evaluate, and collect receipts.
4. State + Next Action
Persist, repeat, report, or escalate.
Core contract: objective, trigger, discover/intake, workspace, context, delegation, verification, state, budget, escalation, exit.
