short_description: An A2A agent network that reviews Python dependencies
---

# parley

Four agents, one protocol. Ask about a Python dependency and watch the
delegations cross the network.

This Space is the browser build: Hugging Face static Spaces serve files, not
Python, so the three specialist agents run in the page and call PyPI, OSV.dev
and the GitHub REST API directly. The A2A envelopes, agent cards, task states
and agent-to-agent delegations are the same shapes the FastAPI build produces.

Routing here uses the deterministic keyword baseline, and answers use the
template summarizer — an API key cannot be shipped to a public page. Pick
**recorded** in the router selector on any sample question to replay a real
Gemini-routed run captured at build time.
