# ollie

Ollie is an AI agent runtime. A single binary (`olliesrv`) exposes agent sessions
over a single surface: a **9P2000 filesystem**. The core is deliberately minimal;
capabilities come from composing small pieces — tool executables, skill files,
metadata sidecars — rather than building a monolithic framework.

## Building

```sh
git clone --recurse-submodules https://git.lneely.de/lkn/ollie.git
cd ollie
just
```

Requires [just](https://github.com/casey/just):

```sh
cargo install just
```

See [`doc/usage.md`](doc/usage.md) for usage instructions.

## Configuration

### Environment: `~/.config/ollie/env`

```
OLLIE_BACKEND=openai           # ollama | openai | anthropic | copilot | kiro (default: ollama)
OLLIE_OPENAI_URL=https://openrouter.ai/api
OLLIE_OPENAI_KEY=sk-or-...
OLLIE_ANTHROPIC_KEY=sk-ant-...
OLLIE_COPILOT_TOKEN=...
OLLIE_KIRO_TOKEN=...           # bearer token or sqlite:// path (auto-detected from Kiro CLI if unset)
OLLIE_MODEL=qwen/qwen3-235b-a22b
OLLIE_COMPLETE_BACKEND=ollama             # backend for code completion
OLLIE_COMPLETE_MODEL=qwen3:latest         # model for code completion
```

Everything lives under `$XDG_CONFIG_HOME/ollie/` (default: `~/.config/ollie/`) — tools in `tools/`, memory in `memory/`, agents in `agents/`, prompts in `prompts/`, skills in `skills/`. Shell environment variables take precedence over the env file.

## What you can do

| Capability | How |
|---|---|
| **CLI** | `o` — unified namespace CLI with `read`, `write`, `readloop`, `ls`, `ctl`, `prompt`, `tail`, `env`, `stop`, `kill` |
| **Terminal TUI** | `o tui` — tmux + two shell commands, no widgets |
| **One-shot LLM** | `o generate "explain monads"` or `echo "prompt" \| o generate` |
| **Code completion** | `o complete '{"file":"main.go","prefix":"func "}'` or `echo '{"file":"..."}' \| o complete` |
| **Task routing** | `o route "implement login"` or `echo "task" \| o route` → `backend=X model=Y` |
| **Run an agent** | Create a session + agent via 9P — then connect with any frontend ([ellie](doc/ellie.md), KDE (GUI/KRunner/Kate), `o tui`) |
| **Remote execution** | Set `remote=user@host` in session config |
| **Agents** | Write a JSON config in `data/agents/` with agent prompt in `data/prompts/` |
| **Tools** | Drop an executable + `.meta` in `~/.config/ollie/tools/` — then load at runtime via `tool_load` |
| **Domain skills** | Load markdown skill modules at runtime |

`olliesrv` exposes the agent runtime over a single surface: a 9P2000 filesystem.
KDE GUI, Kate plugin, and KRunner all use 9P internally. For a deep dive into the
filesystem, see [`doc/resources/9p.md`](doc/resources/9p.md).
