Harness SDK Host Python
Publishable source for the @zack/harness-sdk-host-python workflow template.
This template generates a Python app that launches agentpm harness --machine through the Python SDK, registers a host model provider, adds a before-model Hook, approves an authored Loop checkpoint, and prints the resulting report summary and trace location.
Generated apps use a local root agent.json. The template does not install a published Agent package; the local Agent depends on the published @zack/react-loop@0.1.0 Loop, while agentpm.harness.json binds runtime services hosted by the Python app.
Before publishing:
agentpm lint
agentpm publish --dry-run
After publishing, smoke the generated app with:
agentpm new @zack/harness-sdk-host-python app-harness-sdk-host-python
cd app-harness-sdk-host-python
cp .env.local.example .env.local
uv sync
uv run python -m app.main
SDK compatibility update
Version 0.1.1 generates apps with SDK 0.1.17+ and requires AgentPM CLI
0.1.43+ on PATH (or configured through AGENTPM). Publish this version to
make the updated scaffold available through agentpm new.
