Start here · Agent product builders
Build your Hub. Don't rebuild the runtime.
libkungfu is the embeddable local or worker runtime substrate for Agent products. Keep your interface, models, accounts, permissions, cloud, and customers; add durable runtime facts, Episode recovery, and portable KFD evidence.
Your Hub stays yours. UI, models, accounts, billing, cloud, policy, and customer relationships remain with the Hub owner.

01 · Agent Supply Chain · upstream composition
Five responsibilities. Independent owners. One inspectable path.
Kungfu is an open Agent Supply Chain protocol stack for discovering how Agent products cooperate, binding claims to exact software artifacts, establishing purpose-bound trust, preserving durable work facts, and carrying that work across independently owned Hubs.

Claim boundary: Kungfu does not claim that a multi-Hub ecosystem already exists. It proves that Agent discovery, software provenance, trust, durable work state, and portability no longer need to be rebuilt or locked inside each Hub.
