GitHub Templates for Issues, PRs, and Code Ownership

Purpose

Provide guidance for creating effective GitHub templates including issue templates (both Markdown and YAML forms), pull request templates, and CODEOWNERS files.

When to Use This Skill

Use this skill when:

• Creating issue templates (bug reports, feature requests)
• Setting up pull request templates
• Configuring CODEOWNERS files
• Choosing between Markdown and YAML template formats
• Structuring template fields and validation
• Setting up template automation (labels, assignees)

GitHub Template Types

Issue Templates

GitHub supports two formats for issue templates:

Markdown templates (.github/ISSUE_TEMPLATE/*.md):

• Simple format, easy to create
• Good for basic templates
• Limited validation and structure

YAML forms (.github/ISSUE_TEMPLATE/*.yml):

• Structured forms with validation
• Rich field types (dropdowns, checkboxes, textareas)
• Better for complex templates
• Recommended for new projects

Pull Request Templates

Single template (.github/pull_request_template.md):

• Applied to all pull requests
• Simplest setup

Multiple templates (.github/PULL_REQUEST_TEMPLATE/):

• Different templates for different PR types
• Users select which template to use

CODEOWNERS

File location: .github/CODEOWNERS or CODEOWNERS (root) or docs/CODEOWNERS

Defines code ownership and automatic review requests.

Issue Template Formats

When to Use Markdown

Use Markdown templates for:

• Simple projects with straightforward needs
• Legacy templates (already in Markdown)
• Maximum flexibility in structure
• Projects where YAML might be overkill

Example use cases:

• Small personal projects
• Simple bug report forms
• Question templates

When to Use YAML Forms

Use YAML forms for:

• New projects (recommended default)
• Complex templates with validation
• Dropdown selections (severity, priority, versions)
• Required fields and validation
• Better user experience

Example use cases:

• Bug reports with required information
• Feature requests with structured data
• Templates needing dropdowns or checkboxes

Issue Template Patterns

Bug Report Template

Essential fields:

• Description of the bug
• Steps to reproduce
• Expected behavior
• Actual behavior
• Environment (OS, browser, version)

Optional but valuable:

• Screenshots or error messages
• Severity/priority selection
• Affected version dropdown
• Additional context

YAML structure:

name: Bug Report
description: Report a bug or unexpected behavior
labels: ["bug", "needs-triage"]
body:
  - type: markdown
    attributes:
      value: Thanks for reporting! Please fill out the information below.

  - type: textarea
    id: description
    attributes:
      label: Bug Description
      description: Clear description of the bug
    validations:
      required: true

  - type: textarea
    id: reproduction
    attributes:
      label: Steps to Reproduce
      placeholder: |
        1. Go to...
        2. Click on...
        3. See error
    validations:
      required: true

  - type: dropdown
    id: severity
    attributes:
      label: Severity
      options:
        - Low
        - Medium
        - High
        - Critical

Feature Request Template

Essential fields:

• Problem or use case
• Proposed solution
• Alternatives considered

Optional:

• Priority selection
• Related issues
• Willingness to contribute

YAML structure:

name: Feature Request
description: Suggest a new feature or enhancement
labels: ["enhancement"]
body:
  - type: textarea
    id: problem
    attributes:
      label: Problem Statement
      description: What problem does this solve?
    validations:
      required: true

  - type: textarea
    id: solution
    attributes:
      label: Proposed Solution
      description: How should this work?
    validations:
      required: true

  - type: textarea
    id: alternatives
    attributes:
      label: Alternatives Considered
      description: What other solutions did you consider?

Question Template

For projects using GitHub Discussions, redirect to discussions:

name: Question
description: Ask a question (will redirect to Discussions)
body:
  - type: markdown
    attributes:
      value: |
        Questions should be posted in [GitHub Discussions](../../discussions).

        This issue tracker is for bug reports and feature requests only.

Pull Request Templates

Standard PR Template

Essential sections:

• Description of changes
• Type of change (bug fix, feature, refactor)
• Testing checklist
• Breaking changes note

Template structure:

## Description

Brief description of changes

## Type of Change

- [ ] Bug fix (non-breaking change fixing an issue)
- [ ] New feature (non-breaking change adding functionality)
- [ ] Breaking change (fix or feature causing existing functionality to change)
- [ ] Documentation update

## Testing

- [ ] Tests pass locally
- [ ] Added new tests for changes
- [ ] Updated documentation

## Checklist

- [ ] Code follows project style guidelines
- [ ] Self-reviewed the code
- [ ] Commented complex code sections
- [ ] Updated relevant documentation
- [ ] No new warnings generated
- [ ] Added tests proving fix/feature works
- [ ] Dependent changes merged and published

Detailed PR Template

For projects with stricter requirements:

Additional sections:

• Related issues/tickets
• Screenshots (for UI changes)
• Performance impact
• Security considerations
• Deployment notes
• Rollback plan

CODEOWNERS Patterns

Basic Structure

# Default owners for everything
* @organization/core-team

# Specific paths
/docs/ @organization/docs-team
/src/api/ @organization/backend-team
/src/ui/ @organization/frontend-team

# Specific files
package.json @organization/leads
*.md @organization/docs-team

Advanced Patterns

Multiple owners (all must approve):

/critical-path/ @org/security-team @org/lead-engineer

Individual and team ownership:

/infrastructure/ @devops-lead @org/devops-team

Wildcards and exclusions:

# All TypeScript files
**/*.ts @org/typescript-experts

# Except test files
**/*.test.ts @org/qa-team

Best Practices for CODEOWNERS

Keep focused:

• Don't assign too many reviewers (slows down PRs)
• Use teams instead of individuals when possible
• Balance coverage with PR velocity

Organize logically:

• Start with broad rules, refine with specific rules
• Group related paths together
• Comment sections for clarity

Maintain actively:

• Update as team structure changes
• Remove departed team members promptly
• Review quarterly for accuracy

Template Configuration

Template Discovery

GitHub automatically discovers templates in:

• .github/ISSUE_TEMPLATE/ - Issue templates
• .github/PULL_REQUEST_TEMPLATE/ - PR templates (directory for multiple)
• .github/pull_request_template.md - Single PR template
• .github/CODEOWNERS - Code ownership

Template Metadata (YAML)

Issue template frontmatter:

name: Template Name
description: Brief description
title: "[PREFIX] Default title"
labels: ["label1", "label2"]
assignees:
  - username1
  - username2

Available fields:

• name: Template name shown in issue creation
• description: Detailed description
• title: Default issue title (can include placeholders)
• labels: Auto-applied labels
• assignees: Auto-assigned users

Config File

Create .github/ISSUE_TEMPLATE/config.yml to customize issue creation:

blank_issues_enabled: false
contact_links:
  - name: GitHub Discussions
    url: https://github.com/org/repo/discussions
    about: Please ask questions in Discussions
  - name: Security Issues
    url: https://github.com/org/repo/security
    about: Report security vulnerabilities privately
