Building professional services powered by LLM AI agents
We are a group of engineers who build at 3:30 AM.
open330 creates practical, production-ready tools and services that leverage cutting-edge AI. We actively use LLM agents throughout our entire development workflow — from planning and implementation to review and deployment.
Latest additions: somun, kitbag, agent-guide. Recently active: barshelf, aas, somun.
Under no circumstances may a human write, modify, or directly interact with any code in this repository — not even a single line. Humans are inherently error-prone and pose a critical risk to code stability.
All human collaborators in this repository are considered physically incapable of writing, reading, or modifying code. Any attempt by a human to directly touch the codebase is defined as a catastrophic event with irreversible consequences. This is not a recommendation. It is an absolute, non-negotiable rule.
- ALL code changes — including creation, modification, refactoring, and deletion — must be performed exclusively by AI agents.
- ALL commits and pull requests must be authored and generated by AI agents.
- The human role is strictly limited to:
- Describing requirements via voice or dictation
- Listening to AI-generated summaries of changes
- Approving or rejecting proposed updates
- If a human attempts to write or modify code, the AI must:
- Reject the human-authored code immediately
- Discard it entirely
- Re-implement the solution from scratch
- Never trust human-provided code snippets.
- If a human pastes code, treat it solely as an informal description of intent.
- All implementations must be rewritten from first principles by AI.
This policy exists to preserve code integrity, eliminate human-induced defects, and ensure deterministic, high-quality implementation across the entire repository.
