GitHub Raw Fetch Skill

This skill enables fetching raw content from GitHub file URLs by automatically converting standard GitHub URLs to their raw form and retrieving the content.

Key Purpose

"Fetch and display raw content from GitHub file URLs" by converting standard GitHub URLs to raw.githubusercontent.com format and retrieving the file content.

Core Workflow Steps

1. Detect GitHub URL pattern — Identify if the provided URL is a GitHub file URL (contains github.com/.../blob/...)
2. Convert to raw URL — Transform the URL using one of these methods:
   • Replace github.com with raw.githubusercontent.com
   • Remove /blob/ from the path
   • Result: https://raw.githubusercontent.com/USER/REPO/BRANCH/path/to/file.ext
3. Fetch content — Use WebFetch tool with the converted raw URL
4. Present content — Display the fetched content to the user

URL Conversion Examples

Standard to Raw:

• From: https://github.com/actioncloud/github-raw-url/blob/master/index.js
• To: https://raw.githubusercontent.com/actioncloud/github-raw-url/master/index.js

Pattern transformation:

• github.com/USER/REPO/blob/BRANCH/path/file.ext
• → raw.githubusercontent.com/USER/REPO/BRANCH/path/file.ext

Alternative Methods

• Raw button: If browsing GitHub UI, click the "Raw" button and copy the URL
• Query parameter: Append ?raw=true to the standard URL for automatic redirect
  • https://github.com/USER/REPO/blob/BRANCH/path/file.ext?raw=true

Safety Guidelines

• Validate that the URL is a GitHub file URL before conversion
• Handle edge cases like URLs that are already in raw format
• Preserve the correct branch/tag/commit reference during conversion
• Inform user if the URL pattern is not recognized

This skill streamlines fetching GitHub file content without manual URL manipulation.
