name: managing-project-rules description: Creates and updates modular project rules for Claude Code in .claude/rules/ directory. Use when creating, updating, or modifying rule files, organizing project guidelines, setting up code standards, or when user mentions "create rules", "update rules", "add rules", or "rule configuration".

Goal: Create and maintain focused, well-organized rule files in .claude/rules/ following Claude Code best practices.

IMPORTANT: Rules should be concise, focused, and organized by topic. Follow the reference documentation structure.

Workflow

Phase 1: Assessment

• Read reference documentation at references/project-rules-docs.md
• Analyze existing rules in .claude/rules/ to understand patterns
• Check if rule file exists (update vs create)
• Determine rule scope (general vs path-specific)
• Identify appropriate filename and organization

Phase 2: Configuration

• For updates: read existing file and preserve structure
• Define rule topic and scope clearly
• Structure content with clear sections and lists
• Apply YAML frontmatter for path-specific rules
• Keep content focused on one topic

Phase 3: Implementation

• Create new or update existing rule file in .claude/rules/
• Use subdirectories for better organization if needed
• Validate frontmatter syntax for path-specific rules
• Report completion with file location, scope, and changes made

Rules

• One topic per rule file (code-style, testing, security)
• Use descriptive filenames (kebab-case)
• Path-specific frontmatter only when truly needed
• For updates: extend sections, remove duplicates, preserve existing content
• Consult user before major structural changes

Acceptance Criteria

• Rule file created or updated in .claude/rules/ directory
• Content is focused and well-organized
• YAML frontmatter valid for path-specific rules
• Filename is descriptive and follows kebab-case
• No conflicts with existing rules
• Report includes file location, scope, and summary of changes
