dsh-client-ui-rtl

The DeepSeek Harness Web client renders left-to-right by default. For Arabic, Hebrew, Persian, and Urdu content this means bullets sit on the wrong side, table columns run the wrong way, and any sentence that mixes Latin terms with RTL words comes out garbled. dsh-client-ui-rtl marks the affected DOM nodes with the correct direction at render time, restoring natural reading order while leaving left-to-right content completely untouched.

Under the hood it uses a word-dominance script estimator instead of the dir=auto heuristic, avoiding the common failure where a paragraph opens with a Latin product name. A MutationObserver watches for added and changed text during streaming, reconciling direction on every animation frame. Code blocks, form controls, and embedded media are never marked, and no bidi control characters are inserted—only DOM attributes are set.

Built for developers and teams who interact with DeepSeek Harness in RTL languages, especially in technical writing where Latin identifiers and RTL prose constantly interleave. Released under the MIT license with zero configuration required—restart dsh web and the correct direction is there.
