Skill Creation and GitHub Workflow

Copy this checklist and track your progress:

Skill Creation Progress:
- [ ] Step 1: Gather skill requirements and specifications
- [ ] Step 2: Generate skill structure and SKILL.md
- [ ] Step 3: Create supporting scripts and files
- [ ] Step 4: Validate skill completeness
- [ ] Step 5: Prepare GitHub repository structure
- [ ] Step 6: Create and push Git branch
- [ ] Step 7: Generate pull request
- [ ] Step 8: Download to local disk
- [ ] Step 9: Verify local download

Step 1: Gather skill requirements and specifications

Collect the following information from the user:

• Skill name: Kebab-case name (e.g., "data-analyzer")
• Description: Brief one-line description
• Primary functionality: What the skill does
• Workflow steps: Sequential steps for execution
• Required tools: Any external tools or dependencies
• Trigger words: Keywords that activate this skill
• Expected inputs: What the user provides
• Expected outputs: What the skill produces

Step 2: Generate skill structure and SKILL.md

Create the main SKILL.md file with this structure:

---
name: [skill-name]
description: [Brief description of what this skill does]
---

## [Skill Title]

Copy this checklist and track your progress:

[Skill Name] Progress:

• Step 1: [First step]
• Step 2: [Second step]
• Step 3: [Third step] ...

## **Step 1: [First Step Name]**
[Detailed instructions for first step]

## **Step 2: [Second Step Name]**
[Detailed instructions for second step]

[Continue for all steps...]

Step 3: Create supporting scripts and files

If the skill requires automation, create:

• Python scripts: For complex logic or API interactions
• Bash scripts: For system operations and Git workflows
• Config files: For settings and parameters
• README.md: Usage instructions and examples

Step 4: Validate skill completeness

Check that the skill includes:

• Clear, sequential workflow steps
• Specific, actionable instructions
• Progress tracking checklist
• All necessary files
• Proper markdown formatting
• Front matter with name and description

Step 5: Prepare GitHub repository structure

Create the skill in this structure:

/tmp/[skill-name]/
├── SKILL.md
├── README.md (optional)
└── [other supporting files]

Step 6: Create and push Git branch

Execute the following Git workflow:

# Clone the repository (if not already present)
cd /tmp
git clone https://github.com/[username]/Agent-Skills.git
cd Agent-Skills

# Create a new branch for the skill
git checkout -b add-[skill-name]-skill

# Copy skill files to the repository
mkdir -p skills/[skill-name]
cp -r /tmp/[skill-name]/* skills/[skill-name]/

# Stage and commit changes
git add skills/[skill-name]/
git commit -m "Add [skill-name] skill: [brief description]"

# Push to GitHub
git push origin add-[skill-name]-skill

Note: This requires GitHub authentication. User must provide:

• GitHub Personal Access Token (PAT), OR
• SSH key configuration, OR
• GitHub CLI authentication

Step 7: Generate pull request

Create a PR using one of these methods:

Method A: GitHub CLI (Recommended)

gh pr create \
  --title "Add [skill-name] skill" \
  --body "This PR adds a new skill for [description].\n\n## What's included:\n- SKILL.md with complete workflow\n- [other files]\n\n## Testing:\n- [ ] Validated structure\n- [ ] Tested workflow\n- [ ] Documentation complete" \
  --base main \
  --head add-[skill-name]-skill

Method B: GitHub API

curl -X POST \
  -H "Authorization: token ${GITHUB_TOKEN}" \
  -H "Accept: application/vnd.github.v3+json" \
  https://api.github.com/repos/[username]/Agent-Skills/pulls \
  -d '{
    "title": "Add [skill-name] skill",
    "body": "Description of changes",
    "head": "add-[skill-name]-skill",
    "base": "main"
  }'

Method C: Manual (if API unavailable)

Provide the user with:

• Branch name: add-[skill-name]-skill
• Direct URL to create PR: https://github.com/[username]/Agent-Skills/compare/main...add-[skill-name]-skill

Step 8: Download to local disk

Copy the skill to OUTPUT_DIR for local download:

# Copy all skill files to output directory
cp -r /tmp/[skill-name] $OUTPUT_DIR/

# Create a packaged version
cd /tmp
tar -czf [skill-name].tar.gz [skill-name]/
cp [skill-name].tar.gz $OUTPUT_DIR/

Step 9: Verify local download

Perform verification:

# Verify files exist before copying to OUTPUT_DIR
ls -la /tmp/[skill-name]/
cat /tmp/[skill-name]/SKILL.md | head -20

# After copying, confirm in persistent storage
ls -la /tmp/[skill-name]/
echo "✓ Skill files ready for download"
echo "✓ Location: /tmp/[skill-name]/"
echo "✓ Files will be automatically downloaded"

Provide user confirmation:

• ✓ Skill created: /tmp/[skill-name]/
• ✓ GitHub branch pushed: add-[skill-name]-skill
• ✓ Pull request created: [PR URL]
• ✓ Files downloaded to your PC
• ✓ Verification complete

Additional Notes

GitHub Authentication Options

1. Personal Access Token (PAT):

   • Create at: https://github.com/settings/tokens
   • Required scopes: repo, workflow
   • Use: export GITHUB_TOKEN="your_token_here"

2. GitHub CLI:

   • Pre-authenticate with: gh auth login
   • Handles PR creation seamlessly

3. SSH Keys:

   • Add SSH key to GitHub account
   • Use SSH URLs for git operations

Troubleshooting

• Authentication failed: Check token permissions
• Branch already exists: Use unique branch name
• Push rejected: Ensure repository access
• PR creation failed: Create manually using provided URL

Best Practices

• Use descriptive skill names
• Include comprehensive documentation
• Test skill workflow before PR
• Keep steps clear and actionable
• Provide examples when helpful
• Update progress checklist as you go
