The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

alibabaCursor rulealibaba/loongcollector/.cursor/rules/review-standards/code-review.mdc
Code Review Rule. Use this rule when you need expert code review for quality, security, and maintainability. This rule should be used proactively after writing logical chunks of code, before merging pull requests, or when explicitly asked to review code. Example: After implementing a new feature in a Go plugin, use this rule to review the code for potential issues. Example: When asked '请对 PR 1234 进行代码评审', 'Code Review fork/feature/x', '将 fork/feature/x 对比 main 进行CR' use this rule to perform a thorough security-focused review.

AI-powered security analysis of code changes — traces data flow, detects injection, auth bypass, secrets exposure, and unsafe deserialization across files. Use when reviewing pending changes, before release-branch, during verify-work Phase 5, during build-epic Step 0 threat modeling, or when the user says \"security review\" or \"scan for vulns\".

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
