Use when the user asks about Matthias Lübken's talk "A Piece of PI – Embedding The OpenClaw Coding Agent In Your Product" — including questions about embedding Pi (pi.dev) or coding agents in products, the OpenClaw after-sales prototype, Pi's "radical extensibility" and lifecycle hook extensions, tool design for agents ("don't make your agent guess"), agent sessions as event-log trees, malleable software (Ink & Switch), or applying his primitives (agent setup, tools, extensions, sessions) and patterns (workflow, chat, malleable) to current agent-building work.
