ClaudeGate

Review every file Claude Code touches — accept or revert with one click.

Stop flying blind when Claude modifies your codebase. ClaudeGate captures every file change before it happens and surfaces each one as a structured diff — the same accept/reject workflow as Cursor's native AI review, but for Claude Code running in any terminal.

Quick Start

Three steps, no manual config:

1. Install Install ClaudeGate from the VS Code / Cursor Extensions panel.

2. Setup the hook Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run:

ClaudeGate: Setup Hook

This installs a PreToolUse hook into Claude Code that automatically snapshots files before Claude writes them.

3. Run Claude Code normally Use claude in your terminal as usual. When Claude modifies files, ClaudeGate shows a pending count badge in the sidebar — click any file to review the diff.

The Review Flow

1. The ClaudeGate icon in the Activity Bar shows three panels: Pending, Accepted, and Rejected
2. Click any pending file to open VS Code's native diff editor — original on the left, Claude's version on the right
3. ✓ Accept and ✕ Reject inline links appear at the top of the diff — one click, done
4. Accepted files move to the Accepted panel; rejected files are restored to their original content

Features

• Automatic session tracking — hooks fire before every Claude file write; no manual start/stop
• Three independent panels — Pending, Accepted, and Rejected with per-panel collapse and view toggle
• Accept/Reject CodeLens — inline action links at the top of any pending file, in the diff view and the regular editor
• Folder-level actions — accept or reject an entire directory at once (tree view mode)
• Undo your decisions — re-apply Claude's changes from the Rejected panel; un-accept files back to Pending
• Workspace-aware filtering — files modified outside the current workspace (e.g. ~/.claude/settings.json) are hidden from the review panel
• Pending count badge on the sidebar panel header
• Session history archived to ~/.claudegate/history/

How It Works

Claude Code (terminal)
       │
  PreToolUse hook fires before each Write / Edit / MultiEdit
  ~/.claudegate/hook.py snapshots the current file content
       │
  ~/.claudegate/session.json  ←  shared state file
       │
  ClaudeGate extension watches for changes
       └── Updates review panels in real time

The hook captures a file's original content once per session — subsequent Claude writes to the same file don't overwrite the snapshot, so you always diff against the true before-state.

Requirements

Windows: Native Windows is supported. Python must be on your PATH (python or python3). WSL is not required.

Updating the Hook

After updating the extension, re-run ClaudeGate: Setup Hook to install the latest hook script.
