# METATRON — lightweight Ollama terminal harness
A minimal terminal harness for talking to Ollama (hosted on nightmare `10.30.20.29:11434`)
with full system access. Type `metatron` to launch.
## Flow
1. **Model selection** — fetches the live model list from nightmare, numbered menu.
2. **Chat** — streaming REPL against the selected model.
3. **System access** — two ways:
- `!command` — run a shell command directly (e.g. `!dir`, `!whoami`).
- The model calls `run_command` natively (function calling) to execute commands itself.
## Requirements
- Python 3.11 (stdlib only — `urllib`, `subprocess`, `json`). No pip deps.
- Network reach to `10.30.20.29:11434`.
## Install (Commando VM)
```
mkdir C:\Tools\metatron
copy metatron.py metatron.bat C:\Tools\metatron\
setx PATH "%PATH%;C:\Tools\metatron"
```
Then `metatron` from any shell.
## Hardcoded
- Ollama URL: `http://10.30.20.29:11434`
- System prompt + `run_command` tool definition
- Only the model list is dynamic (fetched from `/api/tags`).
## Controls
| Input | Action |
|-------|--------|
| `exit` / `quit` | leave |
| `!<command>` | run a shell command directly |

"""METATRON — lightweight Ollama terminal harness.
Talks to Ollama on nightmare (hardcoded). Launched by typing `metatron`:
1. model selection screen (fetches live models from nightmare)
2. chat REPL with streaming
3. full system access: `!command` runs a shell command directly, and the
model can also run commands via the run_command tool (native function calling).
Stdlib-only (urllib + subprocess). Hardcoded: Ollama URL, system prompt, tool.
Only the model list is dynamic.
