About this skill

An operating system designed from the core up for agents and agentic security requirements. Built on seL4 microkernel with capability-based security and agent-native vibe-coding.

The instructions your AI receives, as published by jordanhubbard/agentos in skills/sel4-platform/SKILL.md and read by ahel’s review.

You are composing agentOS on-target topology, not a Linux distro.

Invariants

  • seL4 is the only kernel-mode code.
  • Root task distributes caps, then idles. No policy there.
  • PDs in docs/TCB.md may own devices. Museum PDs must not be extended.
  • QEMU is hardware. Do not passthrough QEMU virtio-mmio into guests.

Forbidden

  • Adding oom_killer, POSIX spawn/vfs, or vibe-swap-as-NIC.
  • Documenting "rings 1–5".
  • Python or another forbidden implementation language anywhere in the repository.

Helper

Run make gate to validate the generated topology and boot it on both supported QEMU architectures. The topology authority remains generated C and the documented TCB, with no rendered UI artifact.
