# Rule Title

## Context
- When to apply this rule
- Prerequisites or conditions

## Requirements
- Concise, actionable items
- Each requirement must be testable

## Examples
<example>
Good concise example with explanation
</example>

<example type="invalid">
Invalid concise example with explanation
</example>

## Critical Rules
  - Always do X
  - NEVER do Y
```

## File Organization

### Location
- Path: `.cursor/rules/`
- Extension: `.mdc`

### Naming Convention
PREFIX-name.mdc where PREFIX is:
- 0XX: Core standards
- 1XX: Tool configs
- 3XX: Testing standards
- 1XXX: Language rules
- 2XXX: Framework rules
- 8XX: Workflows
- 9XX: Templates
- _name.mdc: Private rules

### Glob Pattern Examples
Common glob patterns for different rule types:
- Core standards: .cursor/rules/*.mdc
- Language rules: src/**/*.{js,ts}
- Testing standards: **/*.test.{js,ts}
- React components: src/components/**/*.tsx
- Documentation: docs/**/*.md
- Configuration files: *.config.{js,json}
- Build artifacts: dist/**/*
- Multiple extensions: src/**/*.{js,jsx,ts,tsx}
- Multiple files: dist/**/*, docs/**/*.md

## Required Fields

### Frontmatter
- description: ACTION TRIGGER OUTCOME format
- globs: `glob pattern for files and folders`
- alwaysApply: {true or false} - when true will be attached to every conversation (but front matter still is important for it to be used!)

### Body
- context: Usage conditions
- requirements: Actionable items
- examples: Both valid and invalid
- critical-rules: summary of short rule bullets that are the most critical to abide by

## Formatting Guidelines

- Use Concise Markdown primarily
- Use some XML tags limited to:
  - <example>
  - <danger>
  - <required>
- Always indent content within XML or nested XML tags by 2 spaces
- Emojies and Mermaid diagrams are allowed if it is not redundant and better explains the rule for the AI comprehension.


## Critical Rules
  - Keep frontmatter description under 120 characters (or less) while maintaining clear intent for rule selection by AI Agent
  - Keep the rule DRY - do not repeate or be redundant or overly explanetory.
  - Use susinct markdown the agent can easily understand.
  - the front matter MUST ALWAYS have description, globs, and alwaysApply, even if the value is null
  - Use standard glob patterns without quotes (e.g., *.js, src/**/*.ts)
  - TRY to keep the total rule line count under 50, better under 25, lines (unless there are diagrams or longer required examples, as that will increase the overall line count)
  - Always include a valid and invalid example
  - Quotes are not needed around glob patterns
