dsh-plugin-manager

In the DeepSeek Harness ecosystem, plugins are installed as npm packages and enabled through Profile bundles. As the number of plugins grows, port collisions, route overlaps, duplicate service providers, and missing dependencies become common headaches, yet there has been no unified runtime control plane for systematic conflict detection and transactional changes. dsh-plugin-manager, built independently from the legacy component-hub, focuses exclusively on providing full lifecycle control over DSH plugins.

Its core capabilities span four dimensions: a seven-type conflict engine covering explicit declarations, duplicate services, routes, commands, ports, duplicate plugin IDs, missing dependencies, and version incompatibility, producing precise risk reports before any change; a standard transaction flow where every toggle, install, or uninstall step goes through snapshot, validation, and execution with automatic rollback on failure; layered verification that escalates from syntax checks and config validation to a real DSH Loader startup; and a discovery marketplace with offline snapshots, one-click install transactions, and job persistence so progress survives process restarts.

It is well suited for developers managing multiple DSH plugins, teams needing systematic plugin governance, and anyone who wants to safely install, update, or uninstall plugins without losing existing configuration. It complements rather than replaces snapshot/rollback or config-migration tools by providing the transactional and conflict-aware control layer on top.
