Crondex is a catalog of ready made recurring tasks, described as cron jobs, that an AI agent or a person can search through, pull, tweak, and schedule. Rather than being a scheduling framework itself, it describes what a project calls a directory, meaning it holds a large library of predefined job definitions covering things like checking whether an SSL certificate is about to expire, auditing dependencies for security issues, or sending cost alerts. Each job in the catalog is stored as a single file describing its schedule, category, and what it actually does when it runs. A job can run as a plain shell command with no AI involved, as a prompt handed to a language model each time it runs, or as a hybrid of both, letting you choose between a cheap deterministic script or a more flexible AI generated response depending on the situation. The tool is used through a command line interface that lets you search for a job matching a plain English description, view a job's full definition, copy it into your own project to customize, and check what time it would next run before deploying it. Once you are happy with a job, crondex can turn it into the actual file needed to run it in different places, including a standard crontab line, a GitHub Actions workflow, a systemd timer, a Docker setup, or a Kubernetes cron job, among other targets. Multiple jobs can also be deployed together using a single manifest file. Crondex can additionally run as an MCP server, a way for AI coding assistants such as Claude to call its search and lookup features directly as tools rather than running the command line version. The catalog currently contains thousands of jobs across dozens of business and technical categories, most of which have been tested to confirm they work as described.
