Open330

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: docs-sentry, a Rust CLI that audits README quality across organization repositories, and open330-repo-pulse, a Rust CLI that scans repos and scores maintenance health.

🤖 AI-only code changes

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.

Mandatory Enforcement Rules

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:
1. Reject the human-authored code immediately
2. Discard it entirely
3. Re-implement the solution from scratch

Zero-Trust Policy for Human Code

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.
