Wall of Shame
"Did My AI Transformation in an afternoon!"
— Sloppy McSlopperson
VP of AI Buzzword Enforcement, ToDoLy
"Finally added AI to my AI! Now my roadmap has AI-powered AI features with AI on top!"
— Chad Disruption
Chief Vibes Officer, StealthMode.io
"Cutline told me NOT to build 47 of my features. Ignored them all. My app has 3 users now (all bots)."
— Brock Shipper
Founder & Full-Stack Everything, MoveF4st.app
"Spent 6 months building in stealth. Cutline would've saved me, but I was too busy grinding."

Engineering Rigor, at Prompt Speed
The Intent-to-Constraint Engine
Your coding agent needs more than vibes—it needs constraints. Cutline automatically extracts security, scalability, and reliability requirements from your ideas and feeds them to your AI.
What it does
Identifies critical non-functionals—auth patterns, rate limits, data privacy, error handling—that most prompts miss.
Your coding agent builds with the rigor of a senior engineer from the first prompt.
The Dependency Logic Guardrail
Your coding agent doesn't know about your existing security policies or reliability constraints. Cutline's Constraint Graph ensures new features respect existing architectural decisions.
What it does
Real-time constraint checking. If a new feature would violate security policies, break rate limits, or introduce reliability issues, your agent knows before writing code.
"Hardened" Spec Injection
Your coding agent is only as secure and reliable as the context you give it. Cutline injects production-grade constraints directly into your agent's context window.
What it does
Provides security policies, reliability requirements, and scalability constraints as structured context your agent can actually use.
70% less rework. Your agent builds production-ready code from the first try.
The Production-Ready "Shift-Left"
Security, scalability, and reliability can't be afterthoughts. Cutline shifts them left—guiding your coding agent to build production-ready from the start.
The result
Your coding agent ships code with enterprise-grade security, scalability, and reliability baked in from day one.
11 Compliance Frameworks. Zero Extra Work.
Cutline automatically detects your stack and loads the right compliance constraints into your coding agent's context. SOC 2 and security baselines for everyone—regulated frameworks only when your code needs them.

Guide Your Coding Agent with Production-Ready Constraints
Give Cursor, Claude Code, and Windsurf the security, scalability, and reliability context they need. Cutline injects production-ready constraints directly into your coding agent—so it builds right the first time.
FREE
Ask your agent to "run an engineering audit" — scans your code for security, reliability, and scalability issues.
PREMIUM
Product-specific constraint graph, RGR remediation plans, pre-mortem analysis, and persona feedback.

What is Safe Vibecoding?
Safe vibecoding is the practice of using generative AI coding agents for rapid software development while maintaining engineering rigor through automated constraint extraction, pre-mortem risk analysis, and dependency mapping. Without proper guidance, coding agents produce technically functional but production-flawed software—security gaps in auth patterns, scalability assumptions that break under load, and reliability issues that only surface in production.
Cutline, built by VibeKiln, is a product engineering platform that guides your coding agent to build with production-ready rigor. Before your AI writes the first line of code, Cutline extracts non-functional requirements for security, scalability, and reliability, runs pre-mortem analysis to identify technical risks, and injects structured constraints directly into your agent's context—so it knows exactly what production-ready means for your system.
The result: your coding agent builds with the same security, scalability, and reliability standards as a senior engineering team—in a fraction of the time. VibeKiln's Cutline integrates directly into AI coding tools like Cursor, Claude Code, and Windsurf via the Model Context Protocol (MCP), providing your agent with validated technical constraints while it works.
