Pi subagents compared

Three subagent extensions for Pi, and how each handles context and durability.

    Armin Ronacher’s subagent extension runs one observable Pi child at a time in tmux. The parent waits for the result, while I can attach to inspect or intervene. Worth preserving when adding hierarchy: synchronous coordination must not mean invisible execution.

    Arnav Gupta’s pi-subagent-manager makes context inheritance explicit. Nested threads receive their parent’s snapshot; independent roots start without its history. Threads stay around for steering and resume. I want synchronous coordination by default, forks for continuity and fresh context for independent review.

    Pi Pocket’s subagent implementation gives each worker a retained conversation and uses durable tasks to deliver messages and report answers. Request IDs and recorded answer IDs prevent duplicate delivery and reporting after restart. The idea worth stealing: make the handoff durable, not just the worker.
