4-step workflowprompt-engineering tool-prompts preference-chains safety harness guided-flow Harness Engineering

Design Layered Tool Prompts with Preference Chains

Structure your tool prompts the way the leading harness does: preference chains up front, usage constraints in the middle, NEVER-guarded safety protocols at the end.

Run this as a guided flow on Flows — verify gates and recovery prompts included →

No inputs required — hit Run to stream each step in order.

Each step streams from its model and feeds the next. BYOK — you pay your provider directly. Add a key in Settings if a step needs one.

Best for

•Recurring tasks you currently copy-paste between tools.
•When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
•Fork and adapt if your inputs differ materially from the author's use case.
