# Regenerate Codex Context Regenerate the Codex context file (`CODEX.md` or `~/.codex/instructions.md`) for OpenAI Codex integration. Performs an **intelligent merge** — preserving team-written content while updating AIWG context. ## Core Principle **Team content is preserved. AIWG content is updated. Full injection used (Codex does not support @-link directives).** ## Important: No @-Link Support Codex context files do not support `@filename` style includes. AIWG content is embedded directly using injection markers: ```markdown <!-- BEGIN AIWG --> [AIWG content] <!-- END AIWG --> ``` This is different from other providers that use the hook file approach. ## Parameters | Flag | Description | |------|-------------| | `--no-backup` | Skip creating backup file | | `--dry-run` | Preview changes without writing | | `--user-level` | Update `~/.codex/instructions.md` instead of project-level `CODEX.md` | | `--migrate` | Extract injection to `AIWG-codex.md` and reference from CODEX.md (future-proofing) | ## Context File Locations | Scope | Path | Use case | |-------|------|----------| | Project-level | `CODEX.md` | Project-specific AIWG context | | User-level | `~/.codex/instructions.md` | User-wide context across all projects | Default: project-level `CODEX.md`. Use `--user-level` for user-wide context. ## Execution Steps ### Step 1: Create Backup Unless `--no-backup` specified, create `CODEX.md.backup-{YYYYMMDD-HHMMSS}`. ### Step 2: Analyze Existing Content Read `C...
