Open330

Building professional services powered by LLM AI agents

Website · Repositories

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: agent-guide, ccusage-fleet, barshelf. Recently active: kiwimu, muxa, amux.

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:
  1. Reject the human-authored code immediately
  2. Discard it entirely
  3. 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.
