Pi Subagents

@tintinweb/pi-subagents

A [pi](https://pi.dev) extension that brings **Claude Code-style autonomous sub-agents and workflow orchestration** to pi. Spawn specialized agents that run in isolated sessions — each with its own tools, system prompt, model, and thinking level. Run them in the background (the default) or block on them, steer them mid-run, resume completed sessions, and define your own custom agent types. When the orchestration shouldn't be improvised, hand a deterministic JavaScript script to the `SubagentWorkflow` tool — `agent()`, `parallel()`, `pipeline()` — and scripts written for Claude Code's `Workflow` tool run here unchanged.

Features

• Claude Code look & feel — same tool names, calling conventions, and UI patterns (Agent, get_subagent_result, steer_subagent) — feels native
• Parallel background agents — spawn multiple agents that run concurrently with automatic queuing (configurable concurrency limit, default 10) and smart group join (consolidated notifications)
• Live widget UI — persistent above-editor widget with animated spinners, live tool activity, token counts, and colored status icons. Configurable via /agents → Settings → Widget: all (every agent), background (default — hides foreground runs, which already render inline as the Agent tool result), or off
• FleetView — Claude Code-style navigable list of main + every running subagent rendered below the editor (earliest-launched first). Press ↓ (or ←) at an empty prompt to jump in, ↑/↓ to move the selection, Enter to open the selected agent's live, auto-updating conversation, Esc to return. Finish
