Context Bundler

Bundle the content of multiple files into a single context file, ready to paste into ChatGPT, Gemini, Claude or any other LLM — without opening each file manually.

Why?

When working with an LLM, you often need to provide context from several files. The usual workflow is painful: open file → Ctrl+A → Ctrl+C → switch to browser → Ctrl+V → repeat for every file.

Context Bundler lets you build a pool of files, generate a single concatenated bundle, and copy it to the clipboard in one click.

Features

Context Bundler Pool panel

A dedicated panel in the Explorer sidebar (and Activity Bar) showing your current file pool:

• Checkboxes to select which files to include in the next bundle (all checked by default).
• ✕ button (on hover) to remove individual files from the pool.
• ⚡ Generate — concatenates all checked files into a bundle file, with clear start/end markers per file.
• 📋 Copy — copies the last generated bundle to the clipboard.
• Last generated timestamp and a link to open the bundle file directly in the editor.

Panel toolbar icons

Explorer context menu

Right-click any file or folder in the Explorer:

Single file:

• Context Bundler: Add File to Pool
• Context Bundler: Remove File from Pool

Multiple files selected or folder:

• Context Bundler: Add All to Pool
• Context Bundler: Remove All from Pool

When a selection contains both files and folders, a confirmation popup asks whether to expand folders recursively or process only the loose files.

Command Palette

All commands are available via Ctrl+Shift+P:

• Context Bundler: Add Active Tab File to Pool — adds the file open in the current editor tab.
• Context Bundler: Remove Active Tab File from Pool
• Context Bundler: Add All Open Tabs to Pool
• Context Bundler: Remove All Open Tabs from Pool

Bundle format

Each file in the bundle is wrapped with clear markers using its relative path:

// ========== START: src/app/my.component.ts ==========
... file content ...
// ========== END: src/app/my.component.ts ==========

The bundle is saved to your system's temp folder (os.tmpdir()/context-bundler/bundle.txt) and is not added to your workspace.

Persistence

The file pool is saved per workspace. It survives closing and reopening VS Code as long as you work in the same workspace folder.

Requirements

No external dependencies.
