CtxSnap VS Code Extension Tracks File Changes for Claude Sessions
What CtxSnap Does
CtxSnap is a VS Code extension that solves the problem of having to re-explain code to Claude AI after starting new sessions mid-project. Instead of manually catching Claude up on changes, the extension automates this process.
Key Features from the Source
- Tracks exactly which files changed since your last Claude session
- Packages changed files into a ready-to-paste handoff block
- Includes actual file contents in the handoff
- Shows a token budget bar calibrated to Claude's 200k context window
- One-click operation: paste into Claude and it immediately knows what changed
- Works with Claude Code when used in the terminal
- 100% local operation with no account needed
- Free tier covers most workflows
How It Works
The developer built CtxSnap after experiencing repeated friction when starting new Claude sessions. Each time they began a new session, they'd spend several minutes explaining what changed, the current state of the code, and what broke. CtxSnap eliminates this re-explanation process by automatically preparing the context Claude needs to continue where you left off.
The extension is available in the VS Code marketplace and the developer specifically seeks feedback from Claude users, as they're the target audience.
