Developer-tool plugins extend DeepSeek Harness around the day-to-day mechanics of software work. This category covers Git and repository views, file navigation, change review, code references, debugging helpers, development metrics, workspace tooling, build or runtime controls, and automation around common engineering tasks. These plugins are grouped here to make developer-facing capabilities easier to compare without mixing them with unrelated UI or general-purpose extensions.
Developer-tool plugins often operate close to repositories, files, shells, Git operations, and development environments. Before installing one, review its requested capabilities, lifecycle scripts, dependencies, write access, shell behavior, source activity, license, and compatibility evidence. A useful developer plugin should improve the workflow without obscuring what code or system access it requires.
