# Mosaic Runtime Adapter — Codex

## MANDATORY — Read Before Any Response

BEFORE responding to any user message, READ:

1. `~/.config/mosaic/AGENTS.md`
2. `~/.config/mosaic/runtime/codex/RUNTIME.md`

Do NOT respond until both files are loaded.

This file (`~/.codex/instructions.md`) exists only as a fallback for direct `codex` launches.
For full injection, use `mosaic codex`.
