900+ agent skills library
An open-source library of over 900 AI agent skills covering Claude, Copilot, Gemini and Cursor was published and promoted as free to use, giving builders a large reusable catalogue of agent behaviors to compose into workflows (x.com).
A GitHub project called Antigravity Awesome Skills has turned AI agent behavior into installable files, with a catalog that now lists 1,372 reusable skills for tools including Claude Code, Gemini Command Line Interface, Cursor and GitHub Copilot. (github.com) The library packages each behavior as a `SKILL.md` file: a plain-text playbook that tells an agent how to handle a recurring task such as code review, Docker debugging, SQL tuning or PDF extraction. The repository says those files can be installed into tool-specific folders or added through its Node Package Manager installer. (github.com 1) (github.com 2) The project’s latest GitHub release, version 9.11.0, was published on April 9, 2026. GitHub showed about 31,900 stars and 5,300 forks on the repository when its releases page was crawled. (github.com) Agent “skills” are reusable instruction bundles for coding assistants, the same way a shell script or template saves a developer from repeating the same setup by hand. Repositories such as Terminal Skills use the same `SKILL.md` format and describe it as an open standard that works across Claude Code, OpenAI Codex, Gemini Command Line Interface and Cursor. (github.com) That cross-tool format is the point of projects like this one. Antigravity’s README says the repository is meant to replace one-off prompt snippets with a searchable catalog of installable skills, bundles and workflows that can move between assistants instead of being rewritten for each one. (github.com) The catalog has grown quickly. GitHub snapshots and package listings show the project was described as a 930-skill collection in recent copies of the README, then 1,273 skills on the Node Package Manager page, and 1,372 skills on the project’s own site and current release materials. (github.com) (npmjs.com) (sickn33.github.io) The maintainers also pitch the library as more than a prompt dump. The project wiki says it is built to help agents with planning, debugging, testing, security reviews, infrastructure work, product workflows and growth tasks, and third-party summaries describe an automated validation pipeline and web discovery app around the files. (github.com) (deepwiki.com) The result is a large public parts bin for people building agent workflows: not a new model, but a growing stack of reusable operating instructions that can be copied, installed and combined across several coding assistants.
