I want to add the "rundgang2025 — Cursor Rules" prompt rules to my project. Repository: https://github.com/ff6347/rundgang2025 Please read the repo to find the rules/prompt file, then: 1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type) 2. If there's an existing rules file, merge the new rules in rather than overwriting 3. Confirm what was added

Creating Effective Cursor Project Rules
This meta-rule provides comprehensive guidance on creating effective Cursor Project Rules. These are .mdc files stored in your project's .cursor/rules directory that help the AI understand your specific codebase, conventions, and preferences. Following these guidelines will help you create rules that are easily understood by both humans and the AI, leading to more consistent and helpful AI interactions.
What are Cursor Project Rules?
Project Rules are the recommended way to provide persistent, project-specific instructions to Cursor's AI. They live alongside your code (in .cursor/rules/) and are automatically activated when files matching their defined patterns (glob) are referenced in chat or other AI features. Think of them as a structured knowledge base for your project, teaching the AI: • Coding conventions and style guides • Architectural patterns • API usage and interfaces • Domain-specific knowledge • Your personal or team preferences
Rule File Structure
While flexible, a well-structured rule file improves clarity for both humans and the AI. Consider including the following components:
1. YAML Frontmatter (Crucial)
Placement: The YAML frontmatter block (--- ... ---) must be the absolute first content in the file. Any leading spaces, lines, or characters can prevent the rule from loading correctly. `yaml --- title: Brief Title of the Rule (e.g., React Component Guidelines) description: Guidelines for [what this rule covers and its purpose, e.g., structuring functional React components] glob: "[pattern/to/match/files/*/.{ext}]" # See examples below alwaysApply: false # Optional: Set to true to always include this rule --- ` • title: A clear, descriptive title (5-7 words recommended). • description: A concise, semantic description. Start with phrases like "Guidelines for..." or "Instructions on..." This likely helps Cursor automatically select the most relevant rule when multiple match. • glob: File pattern(s) that trigger this rule's automatic activation. Be specific. • Examples: _ src/components/**/_.{tsx,jsx} (React components) _ src/server/api/**/_.ts (Server API routes) _ _.{json,yaml,yml} (Configuration files) _ src/utils/!(test).ts (Utility files, excluding tests) _ {package.json,pnpm-lock.yaml} (Specific root files) • alwaysApply (Optional, defaults to false): If true, the rule is included in context regardless of the files being referenced.
