+# Guide: Self-Healing Scripts with `omnipkg run`
+
+The `omnipkg run` command is one of the most powerful features in the ecosystem. It allows you to execute Python scripts in an environment that can **automatically heal itself from package version conflicts at runtime.**
+
+### What Problem Does It Solve?
+
+Imagine you have a script that explicitly requires an older version of a library:
+```python
+# my_script.py
+from importlib.metadata import version
+import rich
+
+rich_version = version('rich')
+assert rich_version == '13.4.2', f"Incorrect rich version! Expected 13.4.2, got {rich_version}"
+
+print("This script is running with the correct, older version of rich!")
+```
+If your main environment has `rich==14.1.0` installed, running this script normally will fail with an `AssertionError`. The traditional solution is to create a whole new virtual environment just for this one script.
+
+`omnipkg` makes this obsolete.
+
+### How to Use `omnipkg run`
+
+You simply prefix your script execution with `omnipkg run` (or `8pkg run`):
+
+```bash
+8pkg run /path/to/my_script.py
+```
+
+### What Happens Behind the Scenes: The Healing Process
+
+When you use `8pkg run`, `omnipkg` acts as an intelligent supervisor:
+
+1.  **Initial Attempt:** It first tries to run your script directly in the current environment for maximum speed.
+2.  **Failure Detection:** If the script fails and prints an error message containing a version conflict (like `AssertionError: Incorrect rich version!...` or a `VersionConflict` error from `pkg_resources`), `omnipkg`'s healing mechanism activates.
+3.  **Conflict Analysis:** It parses the error message to identify the exact package and version the script requires (e.g., `rich==13.4.2`).
+4.  **Bubble Activation:** It then invokes the `omnipkgLoader`. This powerful tool instantly and temporarily modifies your environment in memory:
+    *   It "cloaks" the main environment's version of `rich`.
+    *   It activates the `rich==13.4.2` bubble you previously installed.
+    *   This entire "teleport" happens in **microseconds**.
+5.  **Re-execution:** `omnipkg` immediately re-runs your script within this temporarily modified context. The script now finds the correct version (`13.4.2`) and succeeds.
+6.  **Automatic Restoration:** As soon as the script finishes, the `omnipkgLoader` context is closed, and your environment is instantly restored to its original state, with `rich==14.1.0` active again.
+
+The result is a workflow that never stops, automatically resolving its own dependency issues without any manual intervention.
+
+### Performance
+
+As shown in our tests, this auto-healing process is often **faster** than a standard tool's failure. The initial run might fail in ~130ms, while the entire `omnipkg` heal-and-rerun cycle completes in just **~40ms**.
+
+This feature makes it possible to build robust, resilient scripts that are guaranteed to run, regardless of the state of the underlying environment.
