Musubi

    A multi-agent operating model for AI-assisted development

    Two different LLMs from two different vendors, working as communicating peers — not interchangeable workers. A protocol sharpened through real client work.

    Cross-vendor peers

    Claude (Opus) and OpenAI (Codex) collaborate as asymmetric colleagues — one optimist, one sceptic. The friction between them is the value.

    Evidence-shaped comms

    Every message follows Action / Evidence / Result / Next. Lying about progress becomes structurally awkward.

    Self-improving cadence

    Build → Audit → Harden → Adapt. Each cycle the system revises its own rules. The same finding never appears twice.
