# Retail Local Runner Use this skill when the user wants to run, stop, configure, inspect, or troubleshoot the Retail Shopping Assistant from this repository with app code running locally. ## Core Workflow The deterministic runner is: ```bash python skills/retail-local-runner/scripts/local_runner.py <command> ``` Available commands: - `configure`: create ignored `config-local.yaml` files that point app services to a remote NIM host. - `install-dev`: create `.local-run/dev-venv` and install Python dev/test packages there. - `start`: start local Milvus infra containers, then local memory, guardrails, catalog, chain-server, and UI processes. - `stop`: stop only tracked local app/UI processes and local Milvus infra containers. Never stop remote NIMs. - `status`: show tracked process, port, health, and Milvus infra status. - `logs`: print recent logs from `.local-run/logs`. ## Stop Workflow When the user asks to stop, shut down, tear down, or restart the local Retail Shopping Assistant, run `stop` first. Do not ask for the NIM host and do not check or create `config-local.yaml` files for stop-only requests. ```bash python skills/retail-local-runner/scripts/local_runner.py stop ``` The stop command only kills PID files tracked under `.local-run/pids/` and stops local Milvus infra containers from `docker-compose.yaml`: - `milvus` - `minio` - `etcd` It must not stop or modify the remote NIM machine from `docker-compose-nim-local.yaml`. If ports are still occupied after `stop`, use `status` and `lsof` to report the untracked owner instead of killing unrelated processes. ## Remote NIM Host Before running `configure` or `start`, check whether all three local override files exist: ```bash find shared/configs -name config-local.yaml -print ``` If any override file is missing, ask the user in chat for the remote NIM host URL before running the script. Do not treat the runner's missing-host error as the final answer. Ask exactly: ```text What is the remote NIM host URL? Use the base host without per-model ports, for example http://NIM_HOST. ``` Use one host URL such as `http://NIM_HOST`; the runner derives these endpoints: - LLM: `:8000/v1` - text embeddings: `:8001/v1` - image embeddings: `:8002/v1` - content safety: `:8003/v1` - topic control: `:8004/v1` Run: ```bash python skills/retail-local-runner/scripts/local_runner.py configure --nim-host http://HOST ``` For a fresh start when the URL is already known, this is enough: ```bash python skills/retail-local-runner/scripts/local_runner.py start --nim-host http://HOST ``` ## Local Services The runner starts these local app processes: - memory retriever: `http://localhost:8011` - guardrails: `http://localhost:8012` - catalog retriever: `http://localhost:8010` - chain server: `http://localhost:8009` - UI: `http://localhost:3000` Only Milvus infra remains containerized: ```bash docker compose -f docker-compose.yaml up -d etcd minio milvus ``` If another local Milvus is already healthy at `localhost:19530` with health on `http://localhost:9091/healthz`, the runner reuses that local endpoint instead of creating conflicting Docker containers. `stop` still only stops this repo's tracked app processes and this repo's Compose infra; it does not stop Milvus containers owned by another project. ## Operational Notes - Runtime files live under `.local-run/`; service logs are in `.local-run/logs/`. - Service virtual environments are created under each service's `venv/` directory. - Existing local Milvus on `localhost:19530` is reused when healthy. - Python dev/test packages must be installed into `.local-run/dev-venv`, never the global interpreter: `python skills/retail-local-runner/scripts/local_runner.py install-dev`. - Use `.local-run/dev-venv/bin/python -m pytest ...` for local unit tests after `install-dev`. - UI dependencies are installed into `ui/node_modules` when missing. - The runner creates `ui/public/images -> shared/images` so React dev mode can serve catalog images from `/images/...`, matching the UI Dockerfile behavior. - The runner sets `CONFIG_OVERRIDE=config-local.yaml`, `SHARED_ROOT`, `SHARED_CONFIG_ROOT`, `REACT_APP_API_BASE_URL=http://localhost:8009`, and `BROWSER=none`. - Use `status` before deciding whether to start or stop. - Use `logs --service catalog-retriever --lines 120` when catalog startup is slow; first startup may populate Milvus embeddings through the remote NIMs. ## Validation After editing this skill, validate both folders: ```bash uv run --with pyyaml python "$CODEX_HOME/skills/.system/skill-creator/scripts/quick_validate.py" skills/retail-local-runner uv run --with pyyaml python "$CODEX_HOME/skills/.system/skill-creator/scripts/quick_validate.py" .agents/skills/retail-local-runner ```
