Arai
An instruction file is advice — the model can read CLAUDE.md and still force-push anyway. Arai turns instruction files (CLAUDE.md, AGENTS.md, .cursorrules, and others) into enforcement via native hooks: rules derived from prohibitive language block the tool call outright, advisory rules inject the relevant constraint at the point it applies, and a tamper-evident audit log records, per rule, whether the model actually complied.
Quick Start
curl -sSf https://arai.taniwha.ai/install | sh
cd your-project
arai initArai discovers your instruction files, extracts the rules, classifies their intent, scans your codebase for context, and registers native hooks. In Codex, review and enable the project hooks through /hooks; writing the configuration does not grant host trust. See Codex setup and coverage.
Codex support and the hardening described below require v1.1.2 or newer (released 2026-09-16). Every install path below serves it; to build from source instead, run cargo install --path . --locked from this checkout.
