-# Odysseus Codex Integration
-
-This directory contains the Codex plugin/skill bundle for Odysseus.
-
-## User Flow
-
-1. Open Odysseus Settings > Integrations.
-2. Add a Codex Agent.
-3. Copy the full setup commands shown after the generated token.
-4. Toggle the tools Codex is allowed to use.
-5. Configure the terminal Codex session:
-
-```bash
-export ODYSSEUS_URL=http://your-odysseus-host:7000
-export ODYSSEUS_API_TOKEN=ody_generated_token
-mkdir -p ~/plugins
-curl -fsSL -H "Authorization: Bearer $ODYSSEUS_API_TOKEN" "$ODYSSEUS_URL/api/codex/plugin.zip" -o /tmp/odysseus-codex-plugin.zip
-python3 -m zipfile -e /tmp/odysseus-codex-plugin.zip ~/plugins
-python3 - <<'PY'
-import json
-from pathlib import Path
-
-p = Path.home() / ".agents" / "plugins" / "marketplace.json"
-p.parent.mkdir(parents=True, exist_ok=True)
-if p.exists():
-    data = json.loads(p.read_text())
-else:
-    data = {"name": "personal", "interface": {"displayName": "Personal"}, "plugins": []}
-
-data.setdefault("name", "personal")
-data.setdefault("interface", {}).setdefault("displayName", "Personal")
-plugins = data.setdefault("plugins", [])
-entry = {
-    "name": "odysseus",
-    "source": {"source": "local", "path": "./plugins/odysseus"},
-    "policy": {"installation": "AVAILABLE", "authentication": "ON_INSTALL"},
-    "category": "Productivity",
-}
-data["plugins"] = [item for item in plugins if item.get("name") != "odysseus"] + [entry]
-p.write_text(json.dumps(data, indent=2) + "\n")
-PY
-codex plugin add odysseus@personal
-```
-
-6. Verify:
-
-```bash
-python3 ~/plugins/odysseus/scripts/odysseus_api.py capabilities
-```
-
-Codex must use `/api/codex/*` endpoints. SSH, Docker, direct Python imports, database queries, and MCP internals bypass Odysseus Settings and must not be used for user data access.
