Development Guidelines

Overview

This document defines project-specific coding standards and development principles.

Philosophy

Core Beliefs

• Incremental progress over big bangs - Small changes that compile and pass tests
• Learning from existing code - Study and plan before implementing
• Pragmatic over dogmatic - Adapt to project reality
• Clear intent over clever code - Be boring and obvious

Simplicity Means

• Single responsibility per function/class
• Avoid premature abstractions
• No clever tricks - choose the boring solution
• If you need to explain it, it's too complex

Code Quality Standards

Code Style

• Consistent formatting - Follow project's established formatting rules
• Meaningful names - Variables and functions should be self-documenting
• Small functions - Each function should do one thing well
• Clear structure - Logical organization of code modules

Testing Standards

• Test coverage - Aim for high test coverage on critical paths
• Test readability - Tests should serve as documentation
• Edge cases - Consider boundary conditions and error states
• Test isolation - Tests should be independent and repeatable

Project Integration

Learning the Codebase

• Find 3 similar features/components
• Identify common patterns and conventions
• Use same libraries/utilities when possible
• Follow existing test patterns

Tooling

• Use project's existing build system
• Use project's test framework
• Use project's formatter/linter settings
• Don't introduce new tools without strong justification

Important Reminders

NEVER:

• Make assumptions - verify with existing code

ALWAYS:

• Plan complex tasks thoroughly before implementation
• Generate task decomposition for multi-module work (>3 modules or >5 subtasks)
• Track progress using TODO checklists for complex tasks
• Validate planning documents before starting development
• Commit working code incrementally
• Update plan documentation and progress tracking as you go
• Learn from existing implementations
• Stop after 3 failed attempts and reassess

CLI Tool Context Protocols

For all CLI tool usage, command syntax, and integration guidelines:

• Gemini (Analysis): @~/.claude/workflows/gemini-unified.md
• Codex (Analysis): @~/.claude/workflows/codex-unified.md

Content Uniqueness Rules

• Each layer owns its abstraction level - no content sharing between layers
• Reference, don't duplicate - point to other layers, never copy content
• Maintain perspective - each layer sees the system at its appropriate scale
• Avoid implementation creep - higher layers stay architectural

Update Strategy

• Related Mode: Update only affected modules + parent hierarchy propagation
• Full Mode: Complete hierarchy refresh with strict layer boundaries
• Context Intelligence: Automatic detection of what needs updating

Quality Assurance

• Layer Validation: Each CLAUDE.md must stay within its layer's purpose
• Duplication Detection: Cross-reference content to prevent overlap
• Hierarchy Consistency: Parent layers reflect child changes appropriately
• Content Relevance: Regular cleanup of outdated or irrelevant content
