# Codex Guide: Shared Conventions Cross-cutting guidance that applies to both Agent and Engine work. Domain-specific rules live in `Docs/Codex/BOREALIS_AGENT.md` and `Docs/Codex/BOREALIS_ENGINE.md`. - UI & AG Grid: see `Docs/Codex/USER_INTERFACE.md` for MagicUI styling language and AG Grid patterns (with references to live templates). - Add further shared topics here (e.g., triage process, security posture deltas) instead of growing `AGENTS.md`.
