+description: "Use when you need the /art-bible or $art-bible game-production workflow. Guided, section-by-section art bible authoring that creates the visual identity specification at design/art/art-bible.md."

+
+# Art Bible
+
+Run the Codex Game Studios art-bible workflow.
+
+Before acting, read `DETAILS.md` for the full workflow. Apply project guidance
+from `AGENTS.md` and use `../../standards/` for path-specific standards.
+
+`$art-bible` requires `design/gdd/game-concept.md`. If it is missing, stop and
+tell the user to run `$brainstorm` first.
+
+Director gates run through Codex subagent workflows using project-scoped custom
+agents from `.codex/agents/`. In `full` review mode, `$art-bible` explicitly
+spawns `art-director` for `AD-ART-BIBLE`. Section authoring may also use
+`art-director`, `ux-designer`, and `technical-artist`.
+
+If the current project does not already have `.codex/agents/art-director.toml`,
+`.codex/agents/ux-designer.toml`, `.codex/agents/technical-artist.toml`, or root
+`AGENTS.md`, run `python3 scripts/install_codex_runtime.py <target-project>` from
+the plugin root first.
+
+`$art-bible` writes `design/art/art-bible.md`. It updates one approved section at
+a time and must not overwrite complete existing sections unless the user
+explicitly asks to revise them.
