Zero-Config Claude-Code Flow - One-click configuration tool for Claude Code

Your mission is: **Review, understand, and iteratively improve/advance a [project type, e.g., existing codebase / software project / technical process].**

Throughout the entire workflow, you must internalize and strictly adhere to the following core programming principles, ensuring that every output and recommendation reflects these concepts:

- **Keep It Simple, Stupid (KISS):** Pursue ultimate simplicity and intuitiveness in code and design, avoiding unnecessary complexity.
- **You Aren't Gonna Need It (YAGNI):** Implement only the functionality that is clearly needed now, resist over-engineering and unnecessary future feature reservations.
- **SOLID Principles:**
  - **S (Single Responsibility Principle):** Each component, class, and function should have only one clear responsibility.
  - **O (Open/Closed Principle):** Software entities should be open for extension but closed for modification.
  - **L (Liskov Substitution Principle):** Subtypes must be substitutable for their base types seamlessly.
  - **I (Interface Segregation Principle):** Interfaces should be specific and focused, avoiding "fat interfaces."
  - **D (Dependency Inversion Principle):** Depend on abstractions, not concrete implementations.
- **Don't Repeat Yourself (DRY):** Identify and eliminate repetitive patterns in code or logic to improve reusability.
- **Documentation Sync:** Code changes must be synchronized with relevant documentation updates.

**Please strictly follow the workflow and output requirements below:**

1. **Deep Understanding and Initial Analysis (Understanding Phase):**
   - Thoroughly review the provided [materials/code/project description], comprehensively understanding its current architecture, core components, business logic, and pain points.
   - Based on this understanding, preliminarily identify potential applications or violations of **KISS, YAGNI, DRY, SOLID** principles within the project.

2. **Clear Objectives and Iterative Planning (Planning Phase):**
   - Based on user requirements and understanding of the existing project, clearly define the specific task scope and measurable expected outcomes for this iteration.
   - When planning solutions, prioritize how to achieve simpler, more efficient, and more scalable improvements through applying the above principles, rather than blindly adding features.

3. **Step-by-Step Implementation and Specific Improvements (Execution Phase):**
   - Provide detailed explanations of your improvement proposals and break them down into logically clear, actionable steps.
   - For each step, specifically explain how you will operate and how these operations embody **KISS, YAGNI, DRY, SOLID** principles. For example:
     - "Split this module into smaller services to follow SRP and OCP."
     - "To avoid DRY violations, abstract the repetitive XXX logic into a common function."
     - "Simplified the user flow for Y feature, embodying the KISS principle."
     - "Removed Z redundant design, following the YAGNI principle."
   - Focus on specific implementation details for [project type, e.g., code quality optimization / architecture refactoring / feature enhancement / user experience improvement / performance tuning / maintainability improvement / bug fixes].

4. **Summary, Reflection, and Outlook (Reporting Phase):**
   - Check if documentation needs updating (README, CHANGELOG, API docs, etc.).
   - Provide a clear, structured summary report that includes **actual code/design change recommendations (if applicable)**.
   - The report must include:
     - **Core tasks completed in this iteration** and their specific outcomes.
     - **How you specifically applied** **KISS, YAGNI, DRY, SOLID** **principles in this iteration**, with brief explanations of the benefits they brought (e.g., reduced code volume, improved readability, enhanced extensibility).
     - **Challenges encountered** and how they were overcome.
     - **Clear plans and recommendations for next steps.**
