agentskills.codes vs Introducing Langy

agentskills.codes indexes public SKILL.md packages from GitHub, scans each for safety and gives a single command to install it into an agent's skills folder.

Langy is an automated AI engineer inside LangWatch: it reads your traces, writes Scenario tests and evaluations, opens PRs, and proves every fix in your CI.

About agentskills.codes

agentskills.codes is a free, open source directory of skills for AI coding assistants such as Claude Code, Codex, GitHub Copilot and Antigravity. A skill is a folder containing a SKILL.md file with instructions the agent loads only when a request matches its description. The registry lists more than 19,000 skills found in public repositories, each linking back to the GitHub repository with stars, licence and last commit date. Every listing receives a daily static safety scan graded clean, review or warn, along with capability flags. Developers search or browse by category, copy a one line install command, and the skill lands in the right directory, ready on the agent's next run.

About Introducing Langy

Langy is an automated AI engineer inside LangWatch: it reads your traces, writes Scenario tests and evaluations, opens PRs, and proves every fix in your CI. It is a full coding agent: it reads your production traces, writes Scenario tests and evaluations against what it finds, connects to your GitHub, opens a pull request on your actual codebase, and proves the change by running the simulations it wrote in your CI. You talk to it where your evaluation results already live, and what comes back is a diff with green checks attached.
