Step-by-Step Workflow

4 Easy Steps
01Phase 1

Define Agent Persona

Select a persona preset (e.g. Senior Security Engineer, Technical Writer) or define custom role objectives.

02Phase 2

Configure Behavioral Constraints

Specify rules (e.g., 'Never make up facts', 'Output strictly JSON', 'Be concise and direct').

03Phase 3

Enable Injection Defense

Toggle anti-prompt-leakage and anti-jailbreak instructions to secure your LLM wrapper.

04Phase 4

Copy Unified System Prompt

Click 'Copy Output' to paste directly into your OpenAI, Anthropic, or Gemini API client code.

Real-World Applications

Production AI Agents

Define rock-solid system instructions for customer support bots, coding assistants, and workflow automations.

Jailbreak Hardening

Protect your AI applications from prompt injections that attempt to extract private system guidelines.

Model Fine-Tuning Prep

Standardize system instructions across training datasets for repeatable, aligned responses.
