LLM Context Copier

📖 What is this?

When working with AI assistants like Claude, ChatGPT, or Gemini, you often need to share:

• The content of a specific file you want help with
• The overall structure of your project so the AI understands the context

Without this extension, you'd manually open a file, copy its content, then separately describe your folder layout. That's slow, error-prone, and the AI still lacks full context.

LLM Context Copy solves this in a single right-click. It scans your project, builds an optimized tree of your file structure, appends the content of your chosen file, and puts everything on your clipboard — formatted perfectly for LLMs.

Right-click any file in the Explorer

The Copy for LLM submenu appears on every file and folder — choose your mode.

Clean, structured output — ready to paste

The copied context includes a metadata header, a full annotated project tree with the focus file marked, and the complete file content with language hints.

Token estimate notification

Every copy shows you exactly how much context you're sending — so you never accidentally exceed a model's context window.

Fully configurable via Settings

Customize exclusions, output format, file size limits, tree depth — everything is exposed in VS Code's native Settings UI.

🚀 How to Use

Step 1 — Open a project in VS Code

Open any folder or workspace. The extension works with any language or framework.

Step 2 — Right-click a file

In the Explorer panel (left sidebar) or in the editor tab, right-click the file you want to focus on. You'll see the Copy for LLM submenu.

Step 3 — Choose a copy mode

Step 4 — Paste into your LLM

Go to Claude, ChatGPT, Gemini, or any AI — paste with Ctrl+V. The output arrives pre-formatted with:

• A metadata header showing project name, timestamp, git branch, and focus file
• A full annotated file tree with your focus file marked as ◄ FOCUS
• The complete file content in a fenced code block with the correct language tag

## ⚙️ Configuration

Open Settings with `Ctrl+,` and search for **LLM Context Copy** to see all options:

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `excludePatterns` | `string[]` | `["node_modules", ".git", "dist", ...]` | File/folder names and glob patterns to hide from the tree |
| `maxFileSizeKb` | `number` | `150` | Files larger than this (in KB) show a placeholder instead of their content |
| `maxTreeDepth` | `number` | `10` | How many folder levels deep the tree goes |
| `includeFileStats` | `boolean` | `true` | Show file size and line count in the tree and file header |
| `outputFormat` | `string` | `"markdown"` | Output format: `"markdown"` \| `"xml"` \| `"plain"` |
| `includeGitInfo` | `boolean` | `true` | Include current git branch name in the context header |
| `respectGitignore` | `boolean` | `true` | Parse `.gitignore` and exclude matching paths from the tree |
| `showTokenEstimate` | `boolean` | `true` | Show a notification with token count after every copy |

### Tip — XML format for Claude system prompts

If you use Claude's system prompt or API, switch the output format to XML:

```jsonc
// settings.json
{
  "llmContextCopy.outputFormat": "xml"
}

The output will use <llm-context>, <project-structure>, and <file> tags — ideal for structured prompt engineering.

💡 Prompting tips

After pasting your context, these prompts tend to work well:

• "I'm getting a NullPointerException in the focus file. Here's the full project context:"
• "Refactor the focus file to match the patterns you see in the rest of this project"
• "Write unit tests for the focus file. Follow the conventions you see in the project structure"
• "Based on the project structure, where should I add a new service for X?"
• "Find any bugs or security issues in the focus file, given this project context"

🔒 Privacy

LLM Context Copy is 100% local. It:

• Reads files from your workspace on your machine
• Writes only to your system clipboard
• Makes no network requests
• Sends no telemetry
• Has no runtime dependencies or external services

Your code never leaves your machine until you paste it yourself.
