Claude Code Cache Fix — VS Code Extension

One-click activation of claude-code-cache-fix for Claude Code sessions in VS Code.

What it does

Automatically configures the claudeCode.claudeProcessWrapper setting to load the cache-fix interceptor into every Claude Code session started from VS Code. The interceptor (v2.0.0) includes 15 cache-stability fixes that reduce unnecessary cache rebuilds by up to 99.8%. Compatible with CC v2.1.112 and Opus 4.7.

Prerequisites

Install the interceptor globally:

npm install -g claude-code-cache-fix

Usage

1. Install this extension
2. It auto-enables on first activation if the interceptor is installed
3. Restart any active Claude Code session

That's it. The extension handles the wrapper configuration automatically.

Commands

• Claude Code Cache Fix: Enable — Activate the interceptor
• Claude Code Cache Fix: Disable — Deactivate (restores default Claude Code behavior)
• Claude Code Cache Fix: Show Status — Check if the interceptor is installed and active

How it works

The VS Code Claude Code extension spawns claude as a subprocess. This extension sets claudeCode.claudeProcessWrapper to a bundled Node.js wrapper that:

1. Sets NODE_OPTIONS to load the interceptor via --import
2. Spawns node cli.js with the cache fixes active
3. Passes all arguments through to Claude Code

No native compilation required. Works on Windows, macOS, and Linux.
