# mp-ai-module-controller

Rust controller for starting a local `llama.cpp` server, asking it to map natural-language requests to known local actions, and dispatching exact-match Rust scripts.

## Setup

```sh
cp .env.example .env
# edit LLAMA_MODEL_PATH in .env
cargo build
cargo run -- dictionary generate
git config core.hooksPath .githooks
```

The controller expects `llama-server` from `llama.cpp` to be installed. On this machine the planned binary is `/opt/homebrew/bin/llama-server`; if that path is not present, the controller falls back to `llama-server` on `PATH`.

## Commands

```sh
cargo run -- dictionary generate
cargo run -- serve
cargo run -- query "log hello from codex"
cargo run -- run logger --payload '{"message":"hello from direct dispatch"}'
scripts/precommit-check.sh
```

`serve` starts:

```sh
llama-server --model "$LLAMA_MODEL_PATH" --host "$LLAMA_HOST" --port "$LLAMA_PORT"
```

Optional environment variables:

- `LLAMA_CONTEXT_SIZE`: appended as `--ctx-size`.
- `LLAMA_EXTRA_ARGS`: shell-split and appended to `llama-server`.
- `CONTROLLER_LOG_LEVEL`: tracing log level, default `info`.

## Dictionary

Run `cargo run -- dictionary generate` to create:

- `dictionary/actions.jsonl`: canonical training dictionary, one action record per line.
- `dictionary/actions.index.json`: compact runtime lookup index.

The runtime only dispatches exact `action_id` matches from `actions.index.json`. Aliases and examples are training hints, not executable ids.

## LLM Response Contract

The local model must return compact JSON:

```json
{"action_id":"logger","payload":{"message":"hello"}}
```

Malformed JSON, missing `action_id`, empty `action_id`, aliases, and unknown action ids are rejected without running anything.

## Initial Script

The first registered script is `logger`. It writes JSONL records to `logs/controller-actions.jsonl`. Dispatch is detached: after the controller spawns the script process, it does not monitor completion.

## CI And Hooks

The project includes:

- `.codex/environments/environment.toml` for Codex setup and run actions.
- `.gitea/workflows/ci.yml` for Gitea Actions.
- `.woodpecker.yml` for Woodpecker.
- `.githooks/pre-commit` for local pre-commit checks.
- `scripts/precommit-check.sh` as the shared validation entrypoint.

Enable the hook after cloning:

```sh
git config core.hooksPath .githooks
```
