A comprehensive prompt engineering framework for safe, deterministic AI automation.
VY Prompt Master is a prompt engineering framework designed for Vy (Vercept) – an AI-powered macOS automation agent. It transforms high-level user task descriptions into detailed, executable YAML specifications that Vy can safely and predictably carry out.
Modern AI agents can perform complex computer tasks, but without proper structure, they risk:
- Unpredictable behavior – Actions may vary between runs
- Safety issues – Destructive actions without user consent
- Debugging difficulties – Hard to trace what went wrong
- Hallucination – Claiming completion without verification
VY Prompt Master solves these problems by enforcing a rigorous specification format where every action is:
- Grounded in UI – Tied to visible elements, not abstract concepts
- Verified – Every action has observable success criteria
- Reversible-first – Preferring undo-able actions with safety gates
- Deterministic – Same input produces same output
| Feature | Description |
|---|---|
| Policy Router | Classifies requests as allowed/disallowed/ambiguous |
| UI Grounding | Actions reference specific, visible UI elements |
| Safety Gates | Irreversible actions require explicit confirmation |
| Fallback Paths | Alternatives when primary approach fails |
| Schema Validation | JSON Schema ensures specification consistency |
| Failure Playbooks | Predefined handling for common errors |
- Prompt Engineers building automation for Vy
- AI Developers creating structured agent specifications
- Automation Specialists needing deterministic UI automation
- Organizations requiring auditable, safe AI operations
"If VY cannot verify it, VY should not execute it."
Every step follows the pattern:
locate → confirm_target → act → verify_outcome
This ensures no action proceeds without proper targeting, and no action completes without verification.
