Version License GitHub Issues GitHub Stars

Quick Start​

  1. Install the extension from the VS Code Marketplace.
  2. Open any AL project in VS Code.
  3. Press Ctrl+Shift+P (or Cmd+Shift+P on macOS) and run "AL Copilot Skills Collection: Install Skills".
  4. Skills are deployed to .github/skills/ and instructions to .github/instructions/ in your workspace.
  5. Start using Copilot — skills are automatically picked up when the task matches.

Features​

One-Command Skill Installation​

Open the Command Palette (Ctrl+Shift+P) and run:

  • AL Copilot Skills Collection: Install Skills — Installs all bundled skills and instructions to your workspace.
  • AL Copilot Skills Collection: Update Skills — Updates existing skills to the latest version (with confirmation prompt).

The extension automatically:

  • Creates the .github/skills/ and .github/instructions/ folder structure
  • Copies all skill packages with their references and examples
  • Shows progress notifications during installation
  • Reports exactly how many skills and instruction files were deployed

Bundled Skills​

Each skill is a self-contained package of instructions, references, and templates that turns GitHub Copilot into a specialized AL development assistant.

Agent-Agnostic Skills​

Skills follow the open Agent Skills standard — a portable format adopted by multiple agent products (GitHub Copilot, Claude Code, Cursor, Roo Code, and others). The extension deploys them to .github/skills/ by default, but you can copy them to your agent's preferred location.

Requirements​

  • Visual Studio Code 1.85.0 or higher
  • AL Language Extension for Business Central development
  • GitHub Copilot (or any agent supporting the Agent Skills standard)

How It Works​

When you run "AL Copilot Skills Collection: Install Skills", the extension:

  1. Detects your workspace root folder.
  2. Creates .github/skills/ and .github/instructions/ if they don't exist.
  3. Copies all bundled skill packages (SKILL.md, references, examples) into your workspace.
  4. GitHub Copilot automatically discovers and loads skills when you ask it to perform a matching task.

Each skill folder follows this structure:

.github/skills/
└── bc-api-page-generator/
    ├── SKILL.md              ← Main instructions (loaded by the agent)
    ├── AUTHORS.md            ← Author and co-author information
    ├── CHANGELOG.md          ← Version history
    └── references/           ← Supporting files, examples, templates

Extension Settings​

This extension does not add any VS Code settings. It activates automatically when an AL file is detected in the workspace.
