Copilot Context Manager

Build, manage, and silently inject your system prompt into every Copilot Chat message.

Stop re-pasting your system prompt. Store it once, switch between role-specific prompts instantly, and use @context [your question] to answer anything with your full instructions already in context — no banners, no broken chat flow.

Features

📝 Prompt Library

Store multiple system prompts for different roles: backend dev, frontend, DevOps, code review, etc.
Switch active prompts instantly from the status bar or Command Palette
Import from any .md or .txt file; export to share or back up

🔄 Soft Re-injection with `@context`

@context [your question] silently prepends your full system prompt before answering — only a single italic line ↩ Prompt: Name appears in chat, keeping the conversation clean
No visible prompt dump, no broken history, no lost context

🏗️ Prompt Builder Wizard

5-step guided wizard walks you from domain description → finished prompt
10 built-in domain templates to start from
Or use @context /build [description] to generate a prompt with AI, then save it directly to your library

🔗 Automatic Sync

Sync your active prompt to .github/copilot-instructions.md (workspace) so Copilot picks it up on every message without @context
Sync globally to ~/.github/copilot-instructions.md for cross-project coverage
Save individual prompts as ~/.github/prompts/[id].prompt.md

Quick Start

Install the extension — the status bar shows your active prompt immediately
Create or import a prompt:
- Ctrl+Shift+P → Copilot Context: New Prompt — write one from scratch
- Ctrl+Shift+P → Copilot Context: Import Prompt from File — import an existing .md / .txt
- Ctrl+Shift+P → Copilot Context: Build Prompt with Wizard — guided 5-step builder
Use it: type @context [your question] in Copilot Chat — your prompt is silently prepended

`@context` Chat Commands

Command	Description
`@context [question]`	Answer the question with your system prompt silently prepended
`@context` (no text)	Sync instructions file, show one-line confirmation
`@context /reinject`	Same as no-text — refresh instructions file silently
`@context /build [description]`	AI-generate a prompt from a description, then save it
`@context /show`	Print your active prompt in a code block
`@context /list`	List all prompts in your library
`@context /set`	Open the prompt switcher picker
`@context /apply`	Sync active prompt to workspace `.github/copilot-instructions.md`

Status Bar

The status bar item shows: $(copilot) [Prompt Name]

Click it for a quick-action menu: switch context, build a new prompt, apply to workspace, open editor.

Managing Prompts

Prompts are stored in .vscode/copilot-prompts.json in your workspace:

{
  "activeContext": "backend-dev",
  "contexts": [
    {
      "id": "backend-dev",
      "name": "Backend Development",
      "description": "Node.js / TypeScript API work",
      "prompt": "You are an expert backend engineer specializing in Node.js and TypeScript..."
    },
    {
      "id": "code-review",
      "name": "Code Review",
      "description": "Thorough review mode",
      "prompt": "You are a senior engineer performing a detailed code review..."
    }
  ]
}

Use these placeholders in your prompt — they resolve at injection time:

Variable	Resolves to
`{{workspaceName}}`	Current workspace folder name
`{{fileName}}`	Currently open file path
`{{languageId}}`	Language of the active editor
