Pi TaskExec

Pi TaskExec

Pi TaskExec lets a supervising agent assign bounded, independent investigation, analysis, implementation, and verification tasks to local Pi workers through MCP. The agent can also work directly when delegation would add more overhead than value.

The project grew out of the author's own workflow: using different models or subscription plans for planning and review versus execution. If you also have multiple AI coding subscriptions or model resources, you can try this division of work to make better use of them and keep execution details from crowding the main agent's context.

The author is still evaluating how this approach affects context usage, total token consumption, and actual costs; savings are not guaranteed. It addresses the author's own collaboration needs and may help others with similar workflows. You're welcome to try it and share your experiences, alternative views, or suggestions via Issues.

Highlights

• Runs tasks on local Pi using its locally configured default model, with optional per-worker model and thinking overrides.
• Full worker lifecycle: spawn, status with bounded wait, steer, continue, cancel (pi_abort), and release (pi_release), plus list.
• Read-only inspect (default) and read/write implement capability profiles.
• The Supervisor chooses the working directory; the MCP verifies authorization but never creates worktrees or branches.
• One unified MCP + pi-delegate Skill setup with keyboard multi-select across Codex, Zed, and OpenCode.

Requirements

• Node.js >= 22.20
• An installed and configured pi executable

Quick start

From the project you want to configure, run the unified setup:

npx -y @zguiyang/pi-task-exec@latest setup

v0.3.1 is the current published release. This checkout prepares v0.4.0 with

updated delegation guidance and multi-host CLI flows.

The v0.3.0 worker-interface changes still apply;

if you are upgrading from v0.2.2, follow the

v0.3.0 migration notes.

On a TTY it opens a keyboard multi-select for the hosts (codex, zed, opencode) plus a single scope (project or global), then runs and prints a concise result; a routine run does not print the full plan and does not ask for a Proceed? confirmation. Use --dry-run for the full plan (paths, conflicts, warnings) and --json for stable machine-readable detail. The pi-delegate Skill is installed from this repository (skills/pi-delegate) at the matching release tag through the pinned Skills CLI skills@1.7.1. Selections can also be given up front: --host may be repeated for several hosts, and exactly one --scope applies to the whole run:

npx -y @zguiyang/pi-task-exec@latest setup --host codex --host zed --scope project

Restart each selected host afterward, grant project trust if asked, and verify that pi_list is available inside the host.

Commands

npx -y @zguiyang/pi-task-exec@latest update

npx -y @zguiyang/pi-task-exec@latest uninstall npx -y @zguiyang/pi-task-exec@latest doctor npx -y @zguiyang/pi-task-exec@latest doctor --probe

setup, update, and uninstall share the same keyboard multi-select of hosts and one scope, and also accept repeated --host flags. update replaces the managed MCP entry and Skill files, so previously configured custom settings must be supplied again.

uninstall removes only the managed pi-task-exec MCP entries for the selected hosts and scope. The shared pi-delegate Skill is retained by default; it is removed only when that removal is explicitly requested, which prints a warning and reports the known hosts that still reference it first. For a non-interactive run, add --remove-skill to request that removal.

The existing add and remove subcommands (add mcp, add skill, remove mcp, remove skill) remain available as single-target commands. doctor is read-only; --probe checks the package runtime only and never creates a worker.
