DeepSeek Harness Plugin: dsh-capability-optimizer

The DeepSeek Harness (DSH) plugin ecosystem introduces dsh-capability-optimizer, designed to enhance decision quality by incorporating external expert consultation. The plugin provides role contracts, multiple thinking-effort levels, and a model fallback mechanism, and supports tools such as `consult_expert` and `consult_panel` for obtaining independent evidence. Its core function is to convert consultation into bounded tool calls, with results provided for the Agent to weigh rather than follow directly. It also features automatic consultation (driven by policies and lifecycle reminders), a bilingual interface, and defense in depth, ensuring a safe and controllable expert perspective before critical decisions and code reviews.
