Guide to Choosing Execution Modes: When to Use Full, Plan-Only, and Implementation-Only

Introduction

DevLoop Runner offers three execution modes. By choosing the appropriate mode based on the nature and situation of your task, you can develop more efficiently.

The Three Execution Modes

1. Full (All Phases)

The standard mode that executes all workflow phases.

Processes executed:

• Planning
• Requirements definition
• Design
• Test scenario creation
• Implementation
• Test implementation
• Test execution
• Documentation update
• Report
• Evaluation

Recommended for:

• Adding new features
• Complex changes
• Tasks you're tackling for the first time

2. Plan Only

Executes only the requirements analysis and design phases. No actual code changes are made.

Processes executed:

• Requirements analysis
• Design document creation

Recommended for:

• When you want to review the design before implementation
• When you need to understand estimates and impact scope
• Preliminary review of complex tasks

3. Implementation Only

Executes only the implementation phase based on existing design.

Processes executed:

• Code implementation
• Test execution

Recommended for:

• When design review is complete and you want to proceed with implementation
• Minor fixes
• When specifications are clear

Situational Guide

"I want to add a new feature"

→ Full is recommended

New features require starting from understanding requirements. Use Full mode for comprehensive processing.

"I want to know the impact scope of this change"

→ Plan Only is recommended

First generate design documents with Plan Only mode, confirm impact scope and implementation approach, then proceed with implementation.

"I want to fix a minor bug"

→ Implementation Only is recommended

When the cause and fix method are clear, you can respond quickly with Implementation Only mode.

"I want to review the design before implementing"

→ Plan Only → Review → Implementation Only (two-stage approach)

1. First generate design with "Plan Only"
2. Review design content, update Issue if necessary
3. Execute implementation with "Implementation Only"

Cost and Time Comparison

Mode	Time Required	AI Cost
Full	Long	High
Plan Only	Short	Low
Implementation Only	Medium	Medium

Summary

• Full: Best for new features and complex changes
• Plan Only: Great for preliminary review and inspection
• Implementation Only: For minor changes with clear specifications

By accurately assessing the nature of your task and selecting the appropriate mode, you can achieve efficient and high-quality development.
