    Who it's for: Anyone packaging a repeatable workflow as a skill; power users and developers

    Safety notes

For developers 4

A few strong picks for people who write code.

  • Multi-platform

    systematic-debugging

    Makes the AI find the real root cause of a bug in four phases before it proposes any fix, instead of guessing.

    Who it's for: Developers

    Safety notes

    Bundled find-polluter.sh runs shell commands (npm test on your test files) when the AI chooses to use it. Installing the full superpowers plugin also adds a SessionStart hook that runs a local bash script to inject the using-superpowers instructions into context; it makes no network calls and reads no credentials.

    mcp-builder

    Guides building MCP servers that connect an AI assistant to an outside service or API, in Python or TypeScript, with a way to test them.

    Who it's for: Developers

    Safety notes

How to install

Claude Code and Claude.ai

Each card has the Claude Code commands from the source repo. For Anthropic's skills in Claude.ai, the anthropics/skills README says they are already available on paid plans, or you can upload one as a custom skill.

Cursor

Cursor rules are single .mdc files: create a .cursor/rules/ folder in your project and copy the file into it, per the awesome-cursorrules README.

Codex

Open /plugins in Codex and install from the openai-curated marketplace. That wording comes from the openai/plugins repo's marketplace.json and the marketingskills README, not from an OpenAI install doc, so we mark it "per repo".

Grok Build

xAI's docs say Grok Build reads Claude Code skills, plugins and .claude/rules, and ~/.agents/skills, so most Claude skills here should work there too. The only official Grok skill we found (create-skill) ships built into Grok Build, so it isn't listed.

How we vet

  • Read, not just listed. We read each skill's instructions, listed every bundled file, and read or searched every bundled script for shell commands, network calls, credential access and file writes. Anything we found is in the card's safety notes. We did not run any skill code.
  • License checked per folder. We took the license from the skill folder's own LICENSE.txt first, then the skill's license field, then the plugin manifest, then the repo's root LICENSE. Only Apache-2.0, MIT and CC0-1.0 made the list.
  • Install steps copied, not written. Every install command comes from the source README or marketplace file.
  • Original repos only. We used directory sites only to find skills. They don't show licenses, and their star counts belong to the host repo, which can push copies above the originals. Every link here goes to the original GitHub repo.
  • Plugins can reach other services. Anthropic's plugins include settings (.mcp.json) for remote connectors such as Slack, HubSpot and Canva. They connect only if you authorize them, and the skills listed here work on pasted content without them.
  • Sponsorships. coreyhaines31/marketingskills runs a paid, disclosed sponsorship program. The 3 skills we list from it contain no partner links or promotions; we checked their links.
  • Maintained. Every source repo had commits in 2026.
  • What we left out. About 30 skills in 13 groups: mostly proprietary or missing licenses (about 18 skills, including Anthropic's docx, pdf, pptx and xlsx skills, which are source-available, not open source), duplicates (5), and two groups with heavy shell or network activity.
