DeepSeek Harness just launched Creator Mode, letting users build plugins with natural-language prompts. But developers have been going a step further. Meet dsh-purge, a project that gives developers more control over Harness prompts, permissions, sandbox policies, and tool execution. It has two main modules: Clean is the main control panel. Developers can edit system prompts, switch model-specific rule sets, manage files like AGENTS.md and CLAUDE.md, and adjust approval rules for terminal commands, file operations, and sub-agents. Unlike prompt-only tweaks, dsh-purge patches local @deepseek-ai packages and config files to change how Harness works. It also supports applying, restoring, and uninstalling patches. Drill is built for authorized local security testing, with tools for managing assets, test environments, skills, and knowledge bases. The project also backs up original files. After a Harness update, patches that no longer match the code are skipped or flagged for review rather than forcibly applied. Repository status: The original author's repository is no longer available. GitHub copies now include a team-maintained version and independent mirrors.
