Nothing to preview — install it and call the typed API, or hand it to an agent.
$pip install prism-ai-harness
Why
The contract is the same in every runtime; only the host differs. A team on Node or Python should not have to reimplement durable agent sessions -- threads, modes, tool permissions and subagents, or route through a PHP service to reach it, because the capability happens to have been written in Laravel first. This is that port -- the same behaviour, held to the same shared fixtures rather than to a README that claims parity.
What
Python port of prism-harness -- durable agent sessions -- threads, modes, tool permissions and subagents.
How
pip install prism-ai-harness (or uv add prism-ai-harness). Published as prism-ai-harness, not as the repo name -- the PyPI namespace is global, so the Prism ports carry a prism-ai- prefix.
