+# ollie-acme
+
+acme interface for ollie. Provides a session list window and per-session chat windows, all driven through the 9P filesystem.
+
+## Build
+
+```sh
+cd acme && mk
+```
+
+## Usage
+
+Run `ollie-acme` from within acme. It opens an `ollie/sessions` window listing active sessions. Click a session ID to open its chat window. Tag commands:
+
+| Command | Action |
+|---|---|
+| New | Open `s/new` for editing |
+| Kill *id* | Kill a session |
+| Refresh | Reload the session list |
+
+Chat windows stream new output via `statewait` and expose:
+
+| Command | Action |
+|---|---|
+| Prompt | Open the session's `prompt` file for editing |
+| Stop | Interrupt the current turn |
+| Ctl | Open the session's `ctl` file |
+
+## Kmpl
+
+`acme/scripts/Kmpl` is an acme script for AI code completion. It reads the text before and after the cursor (dot), sends it to `u/complete`, and inserts the result at the cursor position.
+
+Add `Kmpl` to your acme tag or middle-click it to trigger a completion. It uses the `OLLIE_COMPLETE_BACKEND` and `OLLIE_COMPLETE_MODEL` environment variables (same as `u/complete`).
+
+Override per invocation:
+
+```
+Kmpl -model phi-4-mini -backend ollama
+```
