rules

# Codex Rules Codex Rules is automatic once the plugin is enabled. It injects: - static project instructions on `SessionStart` and `UserPromptSubmit` - matching file-specific rules after Codex `apply_patch` by default Dynamic `PostToolUse` output is injected as additional context and is deduplicated per plugin data session. Codex Rules does not rewrite tool output. Supported project sources: - `CONTEXT.md` - `.omo/rules/**/*.md` - `.claude/rules/**/*.md` - `.cursor/rules/**/*.md` - `.github/instructions/**/*.md` - `.github/copilot-instructions.md` Supported environment knobs: - `CODEX_RULES_DISABLED=1` - `CODEX_RULES_MODE=both|static|dynamic|off` - `CODEX_RULES_MAX_RULE_CHARS=<number>` - `CODEX_RULES_MAX_RESULT_CHARS=<number>` - `CODEX_RULES_ENABLED_SOURCES=CONTEXT.md,.omo/rules` The legacy `PI_RULES_*` variables are accepted as fallbacks for users migrating from `pi-rules`.
