dsh-conversation-process-collapse: Collapse Process Lines in DeepSeek Harness Web Conversations

The dsh-conversation-process-collapse plugin uses front-end DOM manipulation to collapse process lines—such as intermediate narration and Think lines—within completed turns in DeepSeek Harness Web into expandable headers, keeping the interface tidy. It only processes already rendered content, does not affect the model experience, and requires no profile override. The state is not persisted; refreshing the page resets it to the default collapsed state.
