```

### 3. Using GitHub CLI for Pull Requests

```bash
# Create PR
gh pr create --title "feat: add new command" --body "Description of changes"
gh pr create --draft  # Create draft PR
gh pr create --base develop --head feature-branch

# List PRs
gh pr list
gh pr list --state open --label bug

# View PR
gh pr view 123
gh pr view 123 --web  # Open in browser

# Review PR
gh pr review 123 --approve
gh pr review 123 --request-changes --body "Please address these issues"
gh pr review 123 --comment --body "Looks good overall"

# Checkout PR locally
gh pr checkout 123

# Merge PR
gh pr merge 123 --squash
gh pr merge 123 --merge
gh pr merge 123 --rebase

# Close PR
gh pr close 123

# Reopen PR
gh pr reopen 123

# Check PR status
gh pr status
gh pr checks 123
```

### 4. Branch Protection Rules

Recommended settings for main/master branch:

**Require pull request reviews:**
- Require 1 approval before merging
- Dismiss stale approvals when new commits are pushed
- Require review from code owners

**Require status checks:**
- Require branches to be up to date
- Required checks:
  - ShellCheck Linting
  - JSON Validation
  - Integration Tests
  - PR Title Check

**Require conversation resolution:**
- All conversations must be resolved

**Additional rules:**
- Require linear history
- Do not allow bypassing settings
- Restrict who can push to matching branches

### 3. Release Workflow

**Step 1: Prepare Release**

```bash
# Ensure you're on main branch
git checkout main
git pull origin main

# Update version in all files
# - plugin.json
# - .claude-plugin/marketplace.json
# - Any package.json files

# Update CHANGES.md

```bash
# Create annotated tag
git tag -a v0.2.0 -m "Release v0.2.0"

# Push tag (triggers release workflow)
git push origin v0.2.0
```

**Step 3: GitHub Release Automation**

Create `.github/workflows/release.yml`:

```yaml
name: Release

on:
  push:
    tags:
      - 'v*.*.*'

permissions:
  contents: write
  issues: write

            if [ -z "$NOTES" ]; then
              NOTES="Release ${VERSION}"
            fi
          else

## GitHub Packages

### 1. Publishing to GitHub Packages

Create `.github/workflows/package.yml`:

```yaml
name: Publish GitHub Package

on:
  release:
    types: [published]

permissions:
  contents: read
  packages: write

jobs:
  publish-package:
    name: Publish to GitHub Packages

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Extract version from tag
        id: version
        run: echo "VERSION=${GITHUB_REF#refs/tags/v}" >> $GITHUB_OUTPUT

      - name: Create package archive
        run: |
          VERSION="${{ steps.version.outputs.VERSION }}"

          mkdir -p dist

          tar -czf dist/plugin-${VERSION}.tar.gz \
            --exclude='.git' \
            --exclude='.github' \
            --exclude='tests' \
            --exclude='.claude' \
            --exclude='*.log' \
            --exclude='dist' \
            --warning=no-file-changed \
            . || [ $? -eq 1 ]

      - name: Create package metadata
        run: |
          VERSION="${{ steps.version.outputs.VERSION }}"
          cat > dist/package.json << EOF
          {
            "name": "@${{ github.repository_owner }}/${{ github.event.repository.name }}",
            "version": "${VERSION}",
            "description": "Claude Code plugin",
            "repository": {
              "type": "git",
              "url": "https://github.com/${{ github.repository }}.git"
            },
            "license": "MIT"
          }
          EOF

      - name: Upload package to release
        uses: softprops/action-gh-release@v1
        with:
          files: |
            dist/plugin-*.tar.gz
            dist/package.json
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

## Advanced GitHub Features

**Setting up a project board:**

```bash
# Create project
gh project create --owner @me --title "Plugin Development"

# Add issue to project
gh project item-add PROJECT_ID --owner @me --url https://github.com/owner/repo/issues/123

# List projects
gh project list --owner @me
```

**Project fields:**
- Status: Todo, In Progress, In Review, Done
- Priority: Low, Medium, High, Critical
- Size: XS, S, M, L, XL
- Sprint: Sprint 1, Sprint 2, etc.

### 2. Milestones

```bash
# Create milestone
gh api repos/:owner/:repo/milestones -f title="v0.2.0" -f description="Second release"

# List milestones
gh api repos/:owner/:repo/milestones

# Add issue to milestone
gh issue edit 123 --milestone "v0.2.0"

# View milestone progress
gh api repos/:owner/:repo/milestones/1
```

### 3. Code Owners

Create `.github/CODEOWNERS`:

```
# Default owner for everything
* @owner

# Specific areas
/scripts/ @owner @script-maintainer
/commands/ @owner @command-maintainer
/.github/ @owner

# Documentation
*.md @owner @docs-team
```

### 4. GitHub Discussions

Enable discussions for:
- Q&A
- Ideas and feature requests
- General discussions
- Announcements

```bash
# List discussions
gh api repos/:owner/:repo/discussions

# Create discussion
gh api repos/:owner/:repo/discussions \
  -f title="New feature idea" \
  -f body="Description" \
  -f category="Ideas"
```

## Repository Settings Best Practices

### 1. General Settings

**Repository visibility:**
- Public for open-source plugins
- Private for proprietary plugins

**Features to enable:**
- Issues
- Projects
- Discussions
- Wiki (optional)

**Features to disable:**
- Sponsorships (unless applicable)

### 2. Branch Protection

**For main/master branch:**
- Require pull request reviews (1 approval)
- Require status checks to pass
- Require conversation resolution
- Require linear history
- Include administrators in restrictions

**For develop branch:**
- Require pull request reviews (1 approval)
- Require status checks to pass

### 3. Security Settings

**Enable:**
- Dependabot alerts
- Dependabot security updates
- Code scanning (CodeQL)
- Secret scanning

**Configure Dependabot:**

Create `.github/dependabot.yml`:

```yaml
version: 2
updates:
  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      interval: "weekly"
    labels:
      - "dependencies"
      - "github-actions"

  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    labels:
      - "dependencies"
      - "npm"
```

### 4. Notifications

Configure notifications for:
- Issues assigned to you
- PRs requesting your review
- CI failures on your branches
- Release notifications

## CI/CD Best Practices

### 1. Workflow Organization

**Separate workflows by purpose:**
- `ci.yml` - Continuous integration (linting, testing)
- `release.yml` - Release automation
- `pr-checks.yml` - Pull request validation
- `package.yml` - Package publishing
- `security.yml` - Security scanning

### 2. Performance Optimization

**Caching:**
```yaml
- name: Cache dependencies
  uses: actions/cache@v4
  with:
    path: |
      ~/.npm
      ~/.cache
    key: ${{ runner.os }}-deps-${{ hashFiles('**/package-lock.json') }}
```

**Conditional execution:**
```yaml
- name: Run tests
  if: contains(github.event.head_commit.message, '[test]') || github.event_name == 'pull_request'
  run: npm test
```

**Job dependencies:**
```yaml
jobs:
  build:
    runs-on: ubuntu-latest
    steps: [...]

  test:
    needs: build
    runs-on: ubuntu-latest
    steps: [...]

  deploy:
    needs: [build, test]
    runs-on: ubuntu-latest
    steps: [...]
```

### 3. Secrets Management

**Required secrets:**
- `GITHUB_TOKEN` - Automatically provided
- API keys (e.g., `GEMINI_API_KEY`)
- Deploy tokens
- Third-party service credentials

**Using secrets:**
```yaml
- name: Run command
  env:
    API_KEY: ${{ secrets.API_KEY }}
  run: ./script.sh
```

### 4. Status Badges

Add to README.md:

```markdown
# Plugin Name

[![CI](https://github.com/owner/repo/workflows/CI/badge.svg)](https://github.com/owner/repo/actions)
[![Release](https://github.com/owner/repo/workflows/Release/badge.svg)](https://github.com/owner/repo/releases)
[![License](https://img.shields.io/github/license/owner/repo)](LICENSE)
[![Version](https://img.shields.io/github/v/release/owner/repo)](https://github.com/owner/repo/releases)
```

## Common Workflows

### 1. Feature Development

```bash
# Create feature branch
git checkout -b feature/new-command

# Make changes and commit
git add .
git commit -m "feat: add new command"

# Push and create PR
git push origin feature/new-command
gh pr create --title "feat: add new command"

# Address review feedback
git add .
git commit -m "refactor: address review feedback"
git push

# Merge when approved
gh pr merge --squash
```

### 2. Bug Fix

```bash
# Create bug fix branch
git checkout -b fix/command-error

# Fix bug and add test
git add .
git commit -m "fix: resolve command error"

# Push and create PR with issue reference
git push origin fix/command-error
gh pr create --title "fix: resolve command error" --body "Closes #123"

# Merge and backport if needed
gh pr merge --squash
```

### 3. Release Process

```bash
# 1. Update versions
# Edit plugin.json, marketplace.json

# 2. Update CHANGES.md
# Add release notes

# 3. Commit and push
git add .
git commit -m "chore: prepare release v0.2.0"
git push origin main

# 4. Create and push tag
git tag -a v0.2.0 -m "Release v0.2.0"
git push origin v0.2.0

# 5. Verify release created
gh release view v0.2.0

# 6. Test installation
/plugin add https://github.com/owner/repo
```

## Troubleshooting

### CI Failures

**ShellCheck failures:**
```bash
# Run locally first
find scripts hooks -name "*.sh" -exec shellcheck {} +

# Fix issues before pushing
```

**JSON validation failures:**
```bash
# Validate locally
jq empty .claude-plugin/plugin.json
jq empty .claude-plugin/marketplace.json

# Use online JSON validator for complex issues
```

**Test failures:**
```bash
# Run tests locally
bash tests/run-tests.sh

# Debug with verbose output
DEBUG=true bash tests/run-tests.sh
```

### Release Issues

**Version mismatch:**
- Ensure all version fields match:
  - `plugin.json`
  - `.claude-plugin/marketplace.json`
  - Git tag

**Missing changelog:**
- Add entry to CHANGES.md before tagging
- Follow Keep a Changelog format

**Release workflow not triggering:**
- Check workflow file syntax
- Verify tag format (v*.*.*)
- Check repository permissions
