GitHub Repository Management Skill

This skill provides comprehensive repository management operations including creating repositories, managing branches, and working with files.

Available Operations

1. Create Repository

Create a new GitHub repository in your account or organization.

2. Fork Repository

Fork an existing repository to your account or specified organization.

3. Create Branch

Create a new branch in a repository from an existing branch.

4. Search Repositories

Search for GitHub repositories using GitHub's search syntax.

5. Get File Contents

Retrieve the contents of a file or directory from a repository.

6. Create or Update File

Create a new file or update an existing file in a repository.

7. Push Multiple Files

Push multiple files to a repository in a single commit.

Usage Examples

Create a New Repository

Public repository:

bash
gh repo create my-awesome-project --public --description "My awesome project" --clone

Private repository:

bash
gh repo create my-private-repo --private --description "Private project" --clone

With README initialization:

bash
gh repo create my-project --public --add-readme

Fork a Repository

Fork to your personal account:

bash
gh repo fork owner/repo-name --clone

Fork to an organization:

bash
gh repo fork owner/repo-name --org my-org --clone

Fork without cloning:

bash
gh repo fork owner/repo-name

Create a Branch

Create from default branch:

bash
gh api repos/owner/repo-name/git/refs -f ref=refs/heads/new-feature -f sha=$(gh api repos/owner/repo-name/git/refs/heads/main --jq '.object.sha')

Using Git directly (if repo is cloned):

bash
cd repo-name
git checkout -b new-feature
git push -u origin new-feature

Search Repositories

Search by keyword:

bash
gh search repos "machine learning" --limit 20

Search with filters:

bash
gh search repos "web framework" --language python --stars ">1000" --limit 10

Search in organization:

bash
gh search repos "org:myorg" --limit 50

Search by topic:

bash
gh search repos "topic:docker" --stars ">100"

Get File Contents

View file contents:

bash
gh api repos/owner/repo-name/contents/path/to/file.txt --jq '.content' | base64 -d

List directory contents:

bash
gh api repos/owner/repo-name/contents/path/to/directory

Get file from specific branch:

bash
gh api repos/owner/repo-name/contents/README.md?ref=develop --jq '.content' | base64 -d

Create or Update File

Create a new file:

bash
echo "file content" | gh api repos/owner/repo-name/contents/path/to/newfile.txt \
  -X PUT \
  -f message="Add new file" \
  -f content=$(echo "file content" | base64) \
  -f branch=main

Update an existing file (requires SHA):

bash
# First, get the file SHA
SHA=$(gh api repos/owner/repo-name/contents/path/to/file.txt --jq '.sha')

# Then update
echo "updated content" | gh api repos/owner/repo-name/contents/path/to/file.txt \
  -X PUT \
  -f message="Update file" \
  -f content=$(echo "updated content" | base64) \
  -f sha="$SHA" \
  -f branch=main

Push Multiple Files

For pushing multiple files, it's recommended to clone the repository and use Git:

bash
# Clone the repository
gh repo clone owner/repo-name
cd repo-name

# Create/modify multiple files
echo "content1" > file1.txt
echo "content2" > file2.txt
mkdir -p src
echo "code" > src/main.py

# Commit and push
git add .
git commit -m "Add multiple files"
git push

Alternative: Using GitHub API for multiple files (requires tree/commit API):

bash
# This is more complex and typically requires a script
# Recommended to use Git directly for multiple files

Common Patterns

Create Repository and Push Initial Code

bash
# Create repository
gh repo create my-project --public --clone
cd my-project

# Add initial files
echo "# My Project" > README.md
echo "print('Hello')" > main.py

# Commit and push
git add .
git commit -m "Initial commit"
git push -u origin main

Fork, Branch, and Push Changes

bash
# Fork the repository
gh repo fork upstream/repo-name --clone
cd repo-name

# Create feature branch
git checkout -b my-feature

# Make changes
echo "new feature" > feature.txt
git add feature.txt
git commit -m "Add new feature"

# Push branch
git push -u origin my-feature

# Create PR (using pull-request-management skill)
gh pr create --title "Add new feature" --body "Description of changes"

Clone Private Repository

bash
# Ensure you're authenticated
gh auth status

# Clone
gh repo clone owner/private-repo

Error Handling

Repository Already Exists

bash
# Check if repo exists first
gh repo view owner/repo-name 2>/dev/null && echo "Exists" || echo "Does not exist"

Insufficient Permissions

bash
# Verify authentication and permissions
gh auth status

# Try refreshing credentials
gh auth refresh

File Not Found

bash
# Verify the file path exists
gh api repos/owner/repo-name/contents/path/to/file.txt 2>&1 | grep -q "Not Found" && echo "File does not exist"

Best Practices

  1. Always specify owner/repo format: Use owner/repo-name not just repo-name
  2. Check authentication first: Run gh auth status before operations
  3. Use descriptive commit messages: Include context about what changed and why
  4. Branch protection: Set up branch protection rules for important branches
  5. Clone for multiple changes: Use Git directly when making multiple file changes
  6. Handle errors gracefully: Check command exit codes and handle failures
