# View workflow run details
gh run view 123456789

# Re-run failed workflow
gh run rerun 123456789 --failed

# Cancel running workflow
gh run cancel 123456789

## Decision Tree: When to Use Which Command

```
Need to work with GitHub?
├─ Repository tasks?
│  ├─ Creating new repo → gh repo create
│  ├─ Forking existing → gh repo fork
│  └─ Getting info → gh repo view
├─ Issue tracking?
│  ├─ Reporting bug → gh issue create --label bug
│  ├─ Feature request → gh issue create --label enhancement
│  └─ Managing existing → gh issue list/edit/close
├─ Code review process?
│  ├─ Submitting changes → gh pr create
│  ├─ Reviewing code → gh pr review
│  └─ Merging approved → gh pr merge
└─ CI/CD monitoring?
   ├─ Check workflow status → gh run list
   ├─ Debug failures → gh run view
   └─ Re-run builds → gh run rerun
```

## Advanced Workflows

### Bulk Operations
```bash
# Close multiple issues
gh issue list --state open --json number --jq '.[].number' | \
  xargs -I {} gh issue close {}

# Approve multiple PRs from trusted contributor
gh pr list --author trusted-dev --json number --jq '.[].number' | \
  xargs -I {} gh pr review {} --approve
```

### Scripting with gh
```bash
#!/bin/bash
# Auto-create PR when pushing to feature branch
if [[ $(git branch --show-current) == feature/* ]]; then
  gh pr create --draft --title "WIP: $(git branch --show-current)" \
    --body "Auto-created PR for feature branch"
fi
```

### API Integration
```bash
# Make custom API calls
gh api repos/:owner/:repo/issues --field state=open
gh api user --jq '.login'

# Pagination
gh api repos/:owner/:repo/issues --paginate --field state=all
```

## Troubleshooting

### Authentication Issues
```
Error: HTTP 401: Bad credentials
```
**Fix:** Re-authenticate with `gh auth login` and ensure token has correct scopes

### Permission Errors
```
Error: HTTP 403: Resource not accessible by integration
```
**Fix:** Check repository permissions and token scopes:
```bash
gh auth status
gh repo view owner/repo  # Verify access
```

### Network/API Issues
```
Error: failed to run git: exit status 128
```
**Fix:** Verify Git configuration and repository URL:
```bash
gh auth setup-git
git remote -v
```

### Large File Uploads
```
Error: file too large
```
**Fix:** Use release assets for large files:
```bash
gh release create v1.0.0
gh release upload v1.0.0 large-file.zip
```

### Workflow Run Failures
```bash
# Debug workflow issues
gh run view 123456789 --log
gh run list --workflow broken.yml --json conclusion
```

## Configuration & Customization

```bash
# Set default editor
gh config set editor vim

# Configure default repository visibility
gh config set prompt disabled

# Set aliases
gh alias set co 'pr checkout'
gh alias set pv 'pr view'

# List all configuration
gh config list
```

## Integration Examples

### Git Hooks Integration
```bash
# In .git/hooks/post-push
#!/bin/bash
gh pr create --draft 2>/dev/null || echo "PR might already exist"
```

### CI/CD Pipeline Usage
```bash
# In GitHub Actions workflow
- name: Create release
  run: gh release create ${{ github.ref_name }} --generate-notes
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
