DeepSeek Harness Unattended Scheduled Task Scheduler: dsh-wb-cron

`dsh-wb-cron` is a local unattended scheduled-task plugin in the DeepSeek Harness (DSH) ecosystem. It addresses the limitation that built-in schedulers cannot run across sessions by integrating the scheduler into the host process and automatically launching the root agent at scheduled times to execute instructions. It supports multiple scheduling modes, including Vixie Cron expressions, fixed intervals, and absolute times, and offers in-process execution, zero dependencies, zero telemetry, session persistence, and conversation continuation. It also includes a built-in three-tier preset fallback strategy and a robust missed-run handling mechanism, ensuring tasks remain stable even when a preset is unavailable. Installation requires adding the plugin via CLI and enabling it in the configuration file; task data is stored in a local directory.
