Lixiaoyiao/deepseek-harness-action is a DeepSeek Harness plugin rated C3 — powerful capability combined with sensitive behavior. It can rewrite the system prompt, executes system commands, eval in build output only, decodes base64 payloads.
Not a plugin — depends on dsh packages but declares no plugin manifest

How to read this
Levels measure capability surface and transparency, not maliciousness. A C3 plugin can be entirely legitimate — a desktop shell genuinely needs subprocesses. The point is that you can see this before installing. See the levels explained and how dsh plugins work.
Findings come from static analysis of shipped code; nothing is executed. Think a flag is wrong? Open an issue — every flag cites the file and line it came from.
