mrq + Claude Code

Why Claude Code Needs Backup Protection

Claude Code is Anthropic's terminal-based agentic coding tool. It works autonomously, reading your codebase, making decisions, and implementing changes across multiple files.

This autonomy is powerful but risky:

• Claude Code makes architectural decisions on its own
• It can delete, move, or refactor files without confirmation
• Changes happen across many files simultaneously
• The AI's interpretation of your task may differ from your intent

When Claude Code misunderstands a task or takes an unexpected approach, recovery without automatic backups is painful.

How mrq Works with Claude Code

mrq monitors your file system independently of Claude Code. It captures snapshots whenever meaningful changes occur, regardless of which tool makes them.

npm install -g mrq-cli@latest
mrq login
mrq watch --daemon

Start the daemon before your Claude Code session. All changes are captured automatically.

Recovery Flow

$ mrq history

Recent Snapshots
────────────────────────────────────────────────────
  14:23:45  abc123  Restructured database layer
                    +312 lines, -245 lines across 15 files

  14:18:22  def456  Added connection pooling
                    +89 lines, -12 lines across 3 files

  14:12:08  ghi789  Initial database module
                    +156 lines across 5 files
────────────────────────────────────────────────────

$ mrq restore def456
✓ Restored to snapshot def456
✓ Current state backed up as jkl012

If Claude Code's database restructuring wasn't what you wanted, you're back to the previous state in one command.

Agentic Workflow Best Practices

Let Claude Code Be Ambitious

With mrq running, you don't need to constrain Claude Code's scope. Ask it to try the aggressive refactor. If it doesn't work out, you're one command from reverting.

Review Before Committing

After Claude Code completes a task, use mrq history to see what changed. Browse snapshots in the dashboard to understand the scope of modifications before committing to git.

Iterate Quickly

Try approach A. If it doesn't work, restore and try approach B. mrq makes iteration cheap.

Terminal Workflow

Both mrq and Claude Code are terminal-native. A typical workflow:

# Terminal 1: Start mrq
mrq watch

# Terminal 2: Run Claude Code
claude

# If something goes wrong
mrq restore abc123

Or use daemon mode to run mrq in the background:

mrq watch --daemon
claude
# Later...
mrq history
mrq restore abc123
