License Header Adder

This skill automates the process of adding license headers to source files.

Usage

When the user asks to "add license headers" or "check licenses":

1. Identify License: Check LICENSE file or package.json/Cargo.toml to determine the project's license (e.g., MIT, Apache 2.0).
2. Scan Files: Look for source files (e.g., .rs, .py, .js, .ts, .c, .cpp, .go) that correspond to the project's main languages.
3. Check Headers: Read the first few lines of each file to see if a license header exists.
4. Add Header: If missing, prepend the appropriate comment block.

Logic

• MIT:

  Copy/*
   * Copyright (c) [Year] [Owner]
   *
   * Permission is hereby granted, free of charge, to any person obtaining a copy...
   * [Standard MIT Text]
   */
  

• Apache 2.0:

  Copy/*
   * Copyright [Year] [Owner]
   *
   * Licensed under the Apache License, Version 2.0 (the "License");
   * you may not use this file except in compliance with the License.
   * ...
   */
  

Configuration

• Prefer using existing comment styles for the language (e.g., // for Rust/JS, # for Python).
• Be careful not to disrupt shebangs (#!) or encoding declarations.
