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:

File	Purpose
types.ts	TodoItem and TodoList types
TodoContext.tsx	React context + TodoProvider
useTodoList.ts	Hook to read/write the todo list
todoWriteTool.ts	createTodoWriteTool factory — AtlasTool with full CDF task-decomposition guidance
useTodoWriteTool.ts	Hook that memoizes the tool with current state access
TodoPanel.tsx	Card UI: progress bar + task rows
TodoItemRow.tsx	Single row with animated status icons
TodoToolResultCard.tsx	Compact summary card for tool call display

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

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

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