 ## Purpose
 
-oh-my-openagent adds multi-model orchestration, LSP tools, and other advanced features to OpenCode. However, it can interfere with normal operation. This tool provides a simple way to enable/disable it.
+oh-my-openagent adds multi-model orchestration, LSP tools, and other advanced features to OpenCode. However, it can interfere with normal operation. This tool provides a simple way to enable/disable it **without modifying the config file**.
+
+## How It Works
+
+The solution uses the `OPENCODE_CONFIG_CONTENT` environment variable, which has higher runtime precedence than the config file. This means:
+
+- The base `opencode.json` stays clean (no plugin entry)
+- The plugin is only injected at runtime when needed
+- No file mutation, no backups, no restore
 
 ## Files
 
-- `omoa.sh` — Shell script for direct use
-- `omoa.mjs` — OpenCode skill for integration with OpenCode sessions and Telegram bot
+- `opencode-start.sh` — Wrapper script that starts OpenCode with/without omoa
+- `omoa-restart.mjs` — OpenCode skill for Telegram bot integration
+- `README.md` — This file
 
 ## Usage
 
 ### Shell Script
 
 ```bash
-./omoa.sh          # Show status
-./omoa.sh on       # Enable oh-my-openagent
-./omoa.sh off      # Disable oh-my-openagent
+./opencode-start.sh          # Start without omoa (vanilla)
+./opencode-start.sh --omoa   # Start with omoa enabled
 ```
 
-### OpenCode Skill
+### Telegram Bot
 
-When registered in `opencode.json`, use `/commands` → `omoa_toggle` in OpenCode or Telegram.
+When registered in `opencode.json` under "skills", use `/commands` in Telegram:
+- `restart_with_omoa` — Restart OpenCode with omoa enabled
+- `restart_without_omoa` — Restart OpenCode without omoa (vanilla)
 
 ## Installation
 
-1. Copy `omoa.sh` and `omoa.mjs` to `/home/kenny/.config/opencode/skills/`
-2. Add to `opencode.json` under "skills":
+1. Copy files to `~/.config/opencode/`
+2. Update systemd service to use `opencode-start.sh`:
+   ```ini
+   [Service]
+   ExecStart=/home/kenny/.config/opencode/opencode-start.sh
+   ```
+3. Add skill to `opencode.json`:
    ```json
-   "omoa": {
-     "description": "Toggle oh-my-openagent plugin on/off",
-     "path": "/home/kenny/.config/opencode/skills/omoa.mjs"
+   "skills": {
+     "omoa-restart": {
+       "description": "Restart OpenCode with/without oh-my-openagent",
+       "path": "/home/kenny/.config/opencode/skills/omoa-restart.mjs"
+     }
    }
    ```
-3. Restart OpenCode server
-
-## Known Issues
-
-- The omoa install command is fragile and may fail silently
-- The `--no-tui` flag requires all options to be specified manually
-- The script does not verify success before restarting services
-- Needs overhaul to handle edge cases better
+4. Restart services

+ *   - restart_without_omoa: Restart OpenCode without oh-my-openagent (vanilla)
+ *
+ * HOW IT WORKS:
