development-guidelines	A comprehensive guide and template for establishing a unified development process and coding conventions across the team. Use when creating development guidelines and when implementing code.	Read, Write, Edit

Development Guidelines Skill

Covers the two elements needed for team development:

1. Coding conventions for implementation (implementation-guide.md)
2. Standardization of the development process (process-guide.md)

Prerequisites

Before starting to create development guidelines, check the following:

Recommended Documents

1. docs/architecture.md (architecture design document) - confirm the technology stack
2. docs/repository-structure.md (repository structure) - confirm the directory structure

The development guidelines define concrete coding conventions and a development process based on the project's technology stack and directory structure.

Priority of Existing Documents

Important: If existing development guidelines are present at docs/development-guidelines.md, follow this priority order:

1. The existing development guidelines (docs/development-guidelines.md) - highest priority

   • They document project-specific conventions and processes
   • They take precedence over this skill's guide

2. This skill's guide - reference material

   • ./guides/implementation.md: general-purpose coding conventions
   • ./guides/process.md: general-purpose development process
   • Use when there are no existing guidelines, or as a supplement

When creating new: Refer to this skill's guides and template When updating: Update while preserving the structure and content of the existing guidelines

Output Destination

Save the development guidelines you create to:

docs/development-guidelines.md

Quick Reference

When Implementing Code

Rules and conventions for code implementation: ./guides/implementation.md

Contents:

• TypeScript/JavaScript conventions
• Type definitions and naming conventions
• Function design and error handling
• Comment conventions
• Security and performance
• Test code implementation
• Refactoring techniques

When Referencing/Defining the Development Process

Git workflow, test strategy, code review: ./guides/process.md

Contents:

• Basic principles (the importance of concrete examples, explaining rationale)
• Git workflow rules (Git Flow branching strategy)
• Commit messages and the PR process
• Test strategy (pyramid and coverage)
• The code review process
• Quality automation

Template

When creating development guidelines: ./template.md

Guide by Use Case

When Developing New Code

1. Confirm naming conventions and coding standards in ./guides/implementation.md
2. Confirm the branching strategy and PR handling in ./guides/process.md
3. Write tests first (TDD)

During Code Review

• Refer to "The Code Review Process" in ./guides/process.md
• Check for convention violations against ./guides/implementation.md

When Designing Tests

• "Test Strategy" in ./guides/process.md (pyramid, coverage)
• "Test Code" in ./guides/implementation.md (implementation patterns)

When Preparing a Release

• "Git Workflow Rules" in ./guides/process.md (policy for merging into main)
• Confirm that commit messages follow Conventional Commits

Checklist

• Coding conventions are defined with concrete examples
• Naming conventions are clear (per language and project-specific)
• An error handling policy is defined
• A branching strategy is decided (Git Flow recommended)
• Commit message conventions are clear
• A PR template is prepared
• Test types and coverage targets are set
• A code review process is defined
• A CI/CD pipeline is established
