@pi-archimedes/todo

Todo list management with auto-clear and live subagent visibility for the Pi coding agent.

Features

• manage_todo_list tool — structured todo tracking with read and write operations
• Auto-clear — when all todos are completed, the list clears itself after a brief 2-second delay
• Multi-column widget — main agent todos on the left, each subagent's todos in their own column to the right
• Live subagent visibility — subagent todos stream through the core bus so you can see what they're working on
• /todos command — toggle the widget or clear todos (/todos clear)
• Session persistence — todos survive /reload via session branch reconstruction

Usage

As a tool

The manage_todo_list tool accepts two operations:

Read current todos:

{
  "operation": "read"
}

Write (replace) the todo list:

{
  "operation": "write",
  "todoList": [
    { "id": 1, "title": "Parse config files", "description": "Read and validate all config files", "status": "in-progress" },
    { "id": 2, "title": "Build state manager", "description": "Implement TodoStateManager class", "status": "not-started" },
    { "id": 3, "title": "Wire up widget", "description": "Connect widget to bus events", "status": "not-started" }
  ]
}

As a command

• /todos — toggle the todo widget visibility
• /todos clear — clear all todos immediately

Todo statuses

Status	Icon	Description
not-started	○	Not yet begun
in-progress	◉	Currently being worked on
completed	✓	Fully finished

Auto-clear

When all todos in the list are marked completed, the widget shows the all-done state for 2 seconds, then auto-clears. No need to manually run /todos clear.

Subagent integration

When installed via pi-archimedes (the meta package), subagent todo events flow through @pi-archimedes/core/bus and appear as separate columns in the widget. Each subagent gets its own column labeled with its agent name. The column auto-removes when the subagent finishes.
