How we rank

Only skills we have read make the list: the file itself was fetched, it has a real description, it scores at least 55 of 100 on quality, its source still exists, its repository has at least 20 GitHub stars, and our safety scan found nothing high-risk. The order then follows adoption (GitHub stars, on a log scale), how squarely it fits this topic, and its quality score (how substantial and well structured the file is and how recently it changed), moved up for a clean safety scan and for real installs through the SkillAgent MCP server, and down for safety notes. At most three come from any one repository, and tools sold on evading bot detection are never listed. We do not rank by install counts reported by a command-line tool: they are easy to inflate, and our research found repositories with no stars claiming hundreds of thousands of installs. The list is recomputed on every visit.

Questions

What is the best Cursor Rule?

claude-task-master by eyaltoledano ranks first: clean safety scan, 28,084 GitHub stars. The full ranking above lists 15 alternatives with their trade-offs.

How do I install one?

Each entry shows a one-line command. `npx skills add` installs a skill for Claude Code, Cursor, Codex, Gemini CLI and other agents that read skill files.

Are these safe to install?

Every file is scanned for instructions that work against you: hidden text, data sent to outside servers, disabled approval prompts, leaked keys. Skills with a warning are never listed here, and 99% of the 81 we compared for this guide came up clean. Read a skill before installing it all the same: it runs with your permissions.
