Integrate Todo List

Add a TodoWrite tool and panel so the in-app Atlas agent can show task progress.

Skip if the app uses the Atlas / EOS sidebar (integrate-fusion-agent). Prerequisite: useAtlasChat + src/atlas-agent/ + @sinclair/typebox from integrate-atlas-chat.

Step 1 — Read the app

Before writing anything, read:

• package.json — confirm @tabler/icons-react is installed; if not, install it with the app's package manager
• src/App.tsx — find where to add TodoProvider
• The file that calls useAtlasChat (likely src/chat/useChatViewModel.ts or src/App.tsx) — this is where the tool gets wired
• The chat view component that renders messages — this is where TodoPanel and TodoToolResultCard go

Step 2 — Create the src/todo/ module

Find the skill directory by running find . -path "*/.agents/skills/integrate-todo-list/code" -type d from the project root.

Read each file from <skill-dir>/code/ and write it into src/todo/ with the same filename:

All files use relative imports (./types, ./TodoContext, etc.) — no changes needed.

Step 3 — Wrap the app in TodoProvider

In src/App.tsx (or the root component), wrap the existing tree with <TodoProvider>:

import { TodoProvider } from './todo/TodoContext'; // adjust path to match app conventions

function App() {
  return (
    <TodoProvider>
      {/* existing children */}
    </TodoProvider>
  );
}

Step 4 — Wire the tool into useAtlasChat

In the file that calls useAtlasChat, add the following. Adjust import paths to match the app's conventions.

import { useRef, useCallback } from 'react';
import { useTodoList } from './todo/useTodoList';
import { useTodoWriteTool } from './todo/useTodoWriteTool';

// Inside the hook/component:
const { todos, setTodos } = useTodoList();
const todoWriteTool = useTodoWriteTool();

// Keep a ref so getAppContext always reads fresh state without re-creating the callback.
const todosRef = useRef(todos);
todosRef.current = todos;

const getAppContext = useCallback(() => {
  const t = todosRef.current;
  if (t.length === 0) return undefined;
  const lines = t.map((item, i) => `${i + 1}. [${item.status}] ${item.content}`);
  return `Current todo list:\n${lines.join('\n')}`;
}, []);

// Add to useAtlasChat options:
const { messages, send, isStreaming, progress, error, reset, abort } = useAtlasChat({
  client: isLoading ? null : sdk,
  agentExternalId: AGENT_EXTERNAL_ID,
  tools: [todoWriteTool],   // add alongside any existing tools
  getAppContext,
});

// In the reset handler, clear the todo list:
const handleReset = useCallback(() => {
  reset();
  setTodos([]);
}, [reset, setTodos]);

// Expose todos in the return value so the view can render TodoPanel:
return { ..., todos };

Step 5 — Render TodoPanel in the chat view

In the component that renders the chat input area, add <TodoPanel> above the input field:

import { TodoPanel } from './todo/TodoPanel'; // adjust path

// In the render:
<TodoPanel todos={todos} />
<YourChatInput ... />

TodoPanel returns null when the list is empty, so it's safe to always render it.

Step 6 — Render TodoToolResultCard for tool call steps

In the component that renders per-message tool calls (typically a steps accordion or similar), branch on the tool name:

import { TodoToolResultCard } from './todo/TodoToolResultCard'; // adjust path

{toolCalls.map((tc, i) =>
  tc.name === 'TodoWrite' ? (
    <TodoToolResultCard key={i} toolCall={tc} />
  ) : (
    <YourDefaultToolCallCard key={i} toolCall={tc} />
  )
)}

Step 7 — Verify

Run the app's type-check command (typically pnpm tsc --noEmit) and confirm there are no errors. If the project has tests, run them to confirm nothing regressed.

Done

The agent can now use TodoWrite to create and track tasks. It will:

• Show a task panel as soon as it starts multi-step work
• Update task status in real-time (pending → in_progress → completed)
• Clear the list automatically when all tasks are done
• Inject the current task list into each prompt via getAppContext so it knows where it left off
