Integrate Todo List
Add a structured task-tracking feature to this Flows app. The agent will use a TodoWrite tool to create and update a task list as it works through multi-step queries, giving the user real-time visibility into what the agent is doing and why.
Prerequisite: integrate-atlas-chat must already be complete — useAtlasChat must be wired (typically from ./atlas-agent/react), src/atlas-agent/ must contain the vendored atlas-agent sources, and @sinclair/typebox, ajv, ajv-formats must be installed per that skill.

Step 1 — Read the app
Before writing anything, read:
package.json— confirm@tabler/icons-reactis installed; if not, install it with the app's package managersrc/App.tsx— find where to addTodoProvider- The file that calls
useAtlasChat(likelysrc/chat/useChatViewModel.tsorsrc/App.tsx) — this is where the tool gets wired - The chat view component that renders messages — this is where
TodoPanelandTodoToolResultCardgo
---
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
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
getAppContextso it knows where it left off
