# Cursor releases Agent SDK for defining and deploying custom agents

> The Agent SDK lets developers define agents as code with tools and skills, test them with evals, and deploy to Cursor or their own infrastructure. Agents can respond to GitHub, GitLab, Slack, webhooks, and cron events. Includes templates for security reviewers, PR autofixers, and triage bots.
