GitHub Copilot CLI Challenge Submission

Build an AI-powered second brain to streamline your content creation workflow using Obsidian and GitHub Copilot CLI.

Overview

As an AI content creator, you need a system that captures, organizes, and enhances your ideas efficiently. By integrating Obsidian—a Markdown-based knowledge management app—with GitHub Copilot CLI, you automate note editing, rewriting, and organization using natural language prompts.

Prerequisites

  • Install Obsidian and set up your Vault (a folder for your notes).
  • Install GitHub Copilot CLI and authenticate with your GitHub account.

Step 1: Open Your Obsidian Vault

Open your terminal and navigate to your Vault directory:

cd /path/to/your/obsidian-vault
Enter fullscreen mode Exit fullscreen mode

Step 2: Launch Copilot CLI

Start Copilot CLI in your Vault directory:

copilot
Enter fullscreen mode Exit fullscreen mode

Grant Copilot CLI permission to read and modify your notes when prompted.

Step 3: Automate Content Workflows

Use natural language prompts to manage and enhance your notes. For example, to rewrite a draft for an AI content creator audience, use:

Act as a Senior Technical Writer. Rewrite the file 'draft_note.md' for an audience of AI Content Creators.

Constraints:
- Use the Google Developer Documentation Style Guide (active voice, present tense).
- Convert all passive sentences to active.
- Remove fluff and redundant adjectives.
- If the note contains code, verify that the explanation matches the logic.

Format:
1. One-sentence summary at the top.
2. Structured Markdown with H2 and H3 headers.
3. A 'Key Takeaways' bulleted list at the end.

Return the full rewritten content.

Step 4: Select a Relevant Cover Image

Ask Copilot CLI to choose a cover image that matches your note’s topic:

Explore the @[DIR] templates folder and choose the most appropriate image as the cover for the note @Build Your AI-Powered Second Brain.md, based on the content. Then please put the selected cover on top of this note
Enter fullscreen mode Exit fullscreen mode

Copilot will select and insert the best image for your note’s theme.
