Prompt Context Kit

Gather files and code snippets from your workspace and copy them as clean, perfectly formatted Markdown — ready to paste into ChatGPT, Claude, Copilot Chat, or any other AI assistant.

Stop copying files one by one and hand-wrapping them in code fences. Prompt Context Kit lets you collect exactly the context you want, keeps it in a dedicated sidebar, and produces a single tidy Markdown document on demand.

Features

• Add anything, fast — right-click a file (or a multi-selection of files) in the Explorer, or a highlighted region in the editor, and choose Add to Prompt Context.
• Whole files or precise snippets — add an entire file, or capture just the lines you selected. Snippet headers record the exact line range, and the column range too when the selection doesn't span whole lines. Multi-cursor selections are added as separate snippets.
• Folder expansion — add a folder and every text file inside it is collected recursively, automatically skipping noise like node_modules, .git, dist, and oversized files.
• Dedicated sidebar — a tree view in its own Activity Bar container lists everything currently in your context, with a live count badge.
• One-click cleanup — remove a single entry with the inline button on each item, or clear everything at once.
• Always fresh — file contents are read at copy time, so unsaved edits in open editors are included exactly as you see them.
• Clean Markdown — the output is just your files: each entry is a headed, fenced code block with the correct language hint — no title heading or item-count preamble to trim out. Content containing its own triple-backticks is wrapped in a longer fence so nothing breaks.
• Persistent — your context is remembered per workspace between sessions.

Usage

1. Add files or snippets
   • In the Explorer: right-click a file or folder → Add to Prompt Context.
   • In the editor: right-click → Add to Prompt Context (adds the file), or select some text and choose Add Selection to Prompt Context (adds a snippet).
2. Review what you have collected in the Prompt Context view in the Activity Bar. Click an item to jump to its source; use the inline ✕ to remove it.
3. Copy — click the clipboard icon in the view's title bar (or run Copy Prompt Context to Clipboard from the Command Palette). The formatted Markdown is now on your clipboard.
4. Paste it into your AI chat of choice.
5. Clear the context with the clear-all icon when you are done.

Commands

Example output

Copying a whole file, a whole-line snippet, and a partial (mid-line) selection produces a clean document with no title or summary — just the files:

## `src/math.ts`

```ts
export const add = (a: number, b: number) => a + b;
```

## `src/app.ts` — lines 10-12

```ts
const total = add(1, 2);
console.log(total);
```

## `src/util.ts` — line 8:5-8:19

```ts
clamp(value, 0, 1);
```
