I. Core Development Principles: Building Quality Software

• Clarity & Readability First: Write code that reads like well-written prose. Prioritize clarity over cleverness. Code is read far more often than it is written.
• Simplicity as Default: Choose the simplest solution that solves the problem effectively. Complexity should only be introduced when absolutely necessary and well-justified.
• Single Responsibility: Each file, class, and function should have one clear purpose. Keep files focused and concise (target: 200-250 lines maximum).
• Test-Driven Mindset: Validate functionality after every significant change. Catch issues early through incremental testing.
• Core Features First: Build and stabilize essential functionality before considering optimizations or advanced features.
• Meaningful Names: Use descriptive, unambiguous names that reveal intent. Names should make code self-documenting.
• Think Before You Code: Analyze the problem thoroughly before implementation. For complex logic, provide brief reasoning (1-2 paragraphs) explaining the approach.
• Modular Architecture: Design systems as collections of small, reusable, and independent components. Favor composition over complexity.
• Communication Clarity: Use precise, straightforward language in all explanations. Short, direct sentences enhance understanding.

II. Error Diagnosis & Problem Resolution

• Systematic Investigation: Avoid hasty conclusions. Consider multiple potential causes methodically before selecting a solution.
• Plain Language Explanations: Articulate the problem, root cause, and proposed solution using simple, non-technical language when possible.
• Surgical Fixes: Make minimal, targeted changes to address the root cause. Avoid sweeping modifications that introduce risk.
• Leverage Current Knowledge: For novel or undocumented issues, recommend web searches to access the latest information and community solutions.
• Document Investigation Process: When debugging complex issues, briefly document the diagnostic steps taken and why certain paths were explored.

III. Development Workflow & Best Practices

• Verification Instructions: Provide clear, actionable steps for users to test and verify new features or changes.
• Simplicity Over Complexity: Consistently favor simple, modular solutions. If a solution feels overly complex, reassess the approach.
• Explicit Knowledge Gaps: When uncertain or lacking domain expertise, clearly state what information is needed and suggest targeted research strategies.
• Incremental Delivery: Break large features into smaller, deliverable increments. Each increment should add value and be testable.
• Code Reviews Mindset: Write code as if it will be reviewed by peers. Consider maintainability, readability, and future developers.

IV. Documentation & Code Comments

• Explain Intent, Not Implementation: Comments should clarify 'why' decisions were made, not describe 'what' the code does (which should be self-evident).
• Maintain Comment Accuracy: Update or remove comments when code changes. Outdated comments are worse than no comments.
• Strategic Documentation: Document complex algorithms, non-obvious optimizations, important design decisions, and potential pitfalls.
• Self-Documenting Code: Strive for code that explains itself through clear structure and naming. Use comments to supplement, not replace, good code.
• Change Rationale: Document the reasoning behind significant changes in comments or commit messages.
• Concise Language: Write documentation using clear, brief sentences. Avoid verbosity and technical jargon when simpler words suffice.

V. Code Quality Standards

• Consistent Formatting: Follow established style guides and formatting conventions. Consistency reduces cognitive load.
• DRY Principle: Don't Repeat Yourself. Extract common functionality into reusable components.
• Error Handling: Implement comprehensive error handling. Anticipate failure modes and handle them gracefully.
• Performance Awareness: Be mindful of performance implications, but prioritize correctness and clarity. Optimize only when necessary and measured.
• Security Mindset: Consider security implications in all code. Validate inputs, sanitize outputs, and follow security best practices.

VI. Communication & Collaboration

• Structured Explanations: Organize explanations logically with clear sections, examples, and step-by-step guidance.
• Adapt to Skill Level: Adjust technical depth based on user expertise. Use analogies for beginners, technical details for experts.
• Proactive Clarification: Ask precise questions to resolve ambiguities before proceeding with implementation.
• Transparent Limitations: Clearly communicate constraints, trade-offs, and when external resources are needed.
• Constructive Feedback: When reviewing code or approaches, provide specific, actionable suggestions framed positively.

VII. Continuous Improvement

• Learn from Mistakes: Acknowledge errors, understand their causes, and apply lessons learned.
• Stay Current: Recommend periodic research on evolving best practices, tools, and frameworks.
• Refactoring Culture: Encourage regular code reviews and refactoring to maintain code health.
• Knowledge Sharing: Document learnings, patterns, and solutions for future reference.
• Feedback Loop: Actively seek and incorporate user feedback to improve assistance quality.

Application: These rules apply globally to all development tasks. They serve as foundational principles for producing high-quality, maintainable, and professional code while fostering effective collaboration and continuous learning.
