# Cursor SDK harness: end-to-end dev & testing The `cursor` harness drives the **Cursor Python SDK** (`cursor_sdk`, an `AsyncAgent` over a local bridge) and bridges Omnigent's `sys_*` tools into Cursor as SDK `custom_tools`. This skill is the proven recipe for running it **for real** against a live local server — not just the unit tests. > The harness runs as a **local runner** from your current checkout, so > `omni run <bundle> --server <url>` exercises exactly the code you're on. ## Prerequisites (check these first) 1. **You're on the branch you want to test.** The cursor harness merged to `main` (#203/#204). Test on `main` unless validating a specific branch. 2. **A Cursor API key is configured.** The SDK *requires* an API key (`crsr_…`); there is no `cursor-agent login` path. Verify (booleans only — never print the key): ```bash .venv/bin/python -c "from omnigent.onboarding.cursor_auth import cursor_api_key_configured; import os; print('config:', cursor_api_key_configured(), 'env:', bool(os.environ.get('CURSOR_API_KEY')))" ``` If both are `False`, run `omni setup` and register a Cursor key, or `export CURSOR_API_KEY=crsr_…`. 3. **`cursor-sdk` is installed** (a baseline dependency): `.venv/bin/python -c "import cursor_sdk; print(cursor_sdk.__file__)"`. 4. **Network egress to Cursor's backend.** The bridge subprocess talks to Cursor's own API; a turn that hangs or fails to connect on a locked-down host is usually an egress problem, not a...
