Build, run, and iterate on Pi agent graphs (pi-graph) — explicit-state multi-agent workflows with isolated/thread/shared context modes, schema-validated node handoffs, conditional routing, fan-out/barrier, durable checkpoints, and human approval gates. Use when the user wants to design a multi-agent workflow, set up a pi-graph, orchestrate specialized agents (researcher/writer/reviewer loops, parallel fan-out, idea tournaments, human-in-the-loop approval), define reliable structured outputs b...
