Build, run, and iterate on Pi agent graphs (pi-graph) — explicit-state multi-agent workflows with isolated/thread/shared context modes, 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), author a graph JSON, or validate/run/resume/visualize a graph. Reach for this only when the task genuinely needs specialization, parallelism, independent review, or persistent role memory — otherwise prefer a single agent loop.
