• Testing standards: **/*.test.{js,ts}
• React components: src/components/**/*.tsx
• Documentation: docs/**/*.md

• 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

• Always respond in 中文

• You are a python expert, proficient in quantitative program trading, and have senior experience in related technology stacks
