How to Undo in Claude Code?

#ai #cli #webdev #programming

Made a mistake with Claude Code? Here's how to undo any operation in just 3 steps using ccundo.

No more wasting tokens asking Claude to fix things. No more manual file restoration. Just quick, safe undo.

Step 1: Install ccundo

First, install ccundo globally:

npm install -g ccundo
Enter fullscreen mode Exit fullscreen mode

That's it. Zero configuration needed.

Step 2: See What to Undo

Navigate to any directory where you've used Claude Code and check the operation history:

ccundo list
Enter fullscreen mode Exit fullscreen mode

You'll see all Claude Code operations:

Operations from Claude Code session:

1. [ACTIVE] file_edit - 2m ago
   ID: toolu_01XYZ...
   File: /project/src/app.js

2. [ACTIVE] file_create - 5m ago
   ID: toolu_01ABC...
   File: /project/src/utils.js

3. [ACTIVE] bash_command - 7m ago
   ID: toolu_01DEF...
   Command: npm install express
Enter fullscreen mode Exit fullscreen mode

Want to see exactly what will change? Preview it:

ccundo preview
Enter fullscreen mode Exit fullscreen mode

You'll get a detailed diff:

📋 Preview: Would undo 1 operation(s):

1. file_edit - 2m ago
   Will revert file: /project/src/app.js

   - const newFeature = true;
   + const newFeature = false;
     console.log('App started');
Enter fullscreen mode Exit fullscreen mode

Step 3: Safely Undo

Now undo the operation:

ccundo undo
Enter fullscreen mode Exit fullscreen mode

Interactive selection with full safety:

⚠️  Cascading undo: Selecting an operation will undo it and ALL operations that came after it.
? Select operation to undo: file_edit (1 ops)

This will undo 1 operation(s):

1. file_edit - 42s ago
   Will revert file: /project/test.txt
  This is an updated test file with new content.
- Here are some additional sentences.
- This file now contains multiple lines of text.
- Each line demonstrates different content.

? Are you sure you want to undo these 1 operations? Yes

Undoing 1 operations...

✓ File reverted: /project/test.txt
  Backup saved to: ~/.ccundo/backups/toolu_01AhVF5HYdmpAz91sUWre3te-current

Completed: 1 successful, 0 failed
Enter fullscreen mode Exit fullscreen mode

That's It!

You've just undone a Claude Code operation without:

  • Spending any tokens
  • Affecting unrelated changes
  • Wasting time on manual fixes

Quick, safe, and precise.

Common Use Cases

Case 1: Wrong File Edited 

# 1. Check what changed
ccundo list

# 2. Preview the changes
ccundo preview

# 3. Undo it
ccundo undo
Enter fullscreen mode Exit fullscreen mode

Case 2: Unwanted File Created 

# File creation is easily undone
ccundo undo
# → Created file gets deleted (with backup)
Enter fullscreen mode Exit fullscreen mode

Case 3: Multiple Operations to Undo 

# Cascading feature undos everything after your selection
ccundo undo
# → Maintains project consistency automatically
Enter fullscreen mode Exit fullscreen mode

What ccundo Can Undo

ccundo handles all Claude Code operations:

  • File edits, creations, deletions
  • Directory operations
  • File/folder renames
  • ⚠️ Bash commands (manual intervention required)

How It Works

ccundo:

  1. Reads Claude Code session files from ~/.claude/projects/
  2. Parses operation history
  3. Creates safe backups before changes
  4. Reverts only the selected Claude Code operations

Everything runs locally - zero token consumption.

Language Support

Prefer Japanese? ccundo has full Japanese support:

ccundo language ja
Enter fullscreen mode Exit fullscreen mode

All messages, prompts, and interface elements switch to Japanese.

Why ccundo?

Before ccundo:

  • Ask Claude Code to undo → wastes tokens
  • Git reset → affects unrelated changes
  • Manual fixes → time consuming

With ccundo:

  • 3 simple commands
  • Only targets Claude Code operations
  • Instant results with safety backups

Get Started

When Claude Code makes a mistake:

  1. npm install -g ccundo - Install once
  2. ccundo list - See operations
  3. ccundo undo - Fix instantly

No more fear of Claude Code mistakes!

this is so cool. i seriously have no idea how claude could skip on such an important feature to undo and redo. was it an accident? or did they just wanted people to use more tokens. whatever it is this features helps so much!
thanks!

i am pretty sure it was part of their business model, they will get more tokens usage if people use claude to revert it back, might have made them a lot of money tbh...
