DeepSeek Harness Plugin Manager is a web-based plugin management interface for the DeepSeek Harness framework that enables inspection, searching, grouping, and control of Cordis plugins.
The tool addresses the need to manage plugins within a running DeepSeek Harness profile without restarting. It provides two complementary components: a plugin manager that hot-loads already installed plugins through Cordis hot module replacement and controls their enablement state, and a marketplace that discovers, inspects, and installs npm plugin bundles. The marketplace leverages a centrally maintained catalog that automatically discovers packages tagged with `dsh-plugin` on GitHub, verifies package authenticity and repository ownership through GitHub Actions, and records whether published packages declare the official `dsh.bundle` metadata.
Developers managing DeepSeek Harness installations should adopt this tool if they need runtime control over plugin state without restarting their profiles, or if they want a curated marketplace for discovering and installing verified plugins. The marketplace's automated verification of package versions and repository ownership provides assurance about plugin authenticity. The tool is built as two independent plugins, so teams can adopt just the manager for controlling existing plugins, just the marketplace for discovery and installation, or both together depending on their workflow needs.
The project maintains separate versioning for its two components through distinct release tags. Development activity centers on the two independent plugin packages, with the marketplace component relying on an automatically generated catalog that GitHub Actions keeps current by discovering and verifying packages across the ecosystem.
