cursor-rules
整理和收集来自不同项目的Cursor规则文件，提供多种编程语言和框架的规则支持。
No outside reports on file
Rules are guidance files, not security controls; malicious or poisoned rules can trick Cursor into unsafe behavior, and auto-fetching rules from untrusted sources adds supply-chain risk.
Based on public adoption and transparency signals as of Oct 22, 2026. Our opinion, not a code audit or security guarantee.

About Cursor Rules
This is a collection of rule files for Cursor (an AI code editor). The rules help guide how Cursor behaves when writing code in different programming languages and frameworks. Users can browse, download, or contribute different rule sets from a shared repository.
Who it’s for
Developers who use Cursor and want to customize how the AI assistant handles coding tasks. Teams looking for standardized coding guidance across multiple projects.
Alternatives
- Cursor's built-in rules and settings: Cursor provides default behavior modes without external dependencies.
- EditorConfig: A standardized format for sharing editor and formatting rules across projects.
- ESLint/Prettier/etc.: Language-specific linting and formatting tools (not AI-focused but more transparent).
- Claude Desktop custom instructions: Using Claude directly with your own written guidelines instead of fetched rule files.
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README. This is a GitHub repository of text rule files rather than an installable package—you typically download rules manually or clone the repo and copy .cursor/rules files into your local projects.
Why this grade

Security reports
No reports found for this package in our research (last checked 2026-10-28).
Risks to watch for
- Rule injection attacks: If rules are auto-downloaded or fetched from untrusted sources, malicious rules could trick Cursor into generating unsafe code or leaking secrets.
- Prompt poisoning: Crafted rule files could contain hidden instructions that override your actual intent and cause Cursor to write harmful code.
- Data in rules: Rules might accidentally document sensitive patterns (API keys, internal paths, passwords) if not carefully reviewed before sharing.
- Supply chain risk: Popular rules could be modified by attackers if the repository or maintainer account is compromised.
- False security from text: A rule file saying 'check for vulnerabilities' doesn't guarantee the AI will actually do it—rules are suggestions, not enforcement.
How to lower the risk
Least-privilege permissions
- Review any rule file before using it; don't auto-fetch from unknown sources.
- Only enable rules matching your actual project needs.
Network isolation
- Keep your Cursor installation and local rules on your machine; avoid cloud sync of sensitive rules.
- Don't fetch rules from random URLs in chat or email.
Monitoring
- Watch Cursor's generated code closely; rules don't prevent bad outputs.
- Audit rule changes if you share them across a team.
Red flags to watch for
- Rules that override safety checks or skip validation steps.
- Rules downloaded from links in chat messages or forums.
- Overly complex rules with hidden logic or obfuscated text.
