dsh-overleaf

Overleaf sends X-Frame-Options and CSP frame-ancestors on every response, so a plain iframe is outright rejected by the browser. dsh-overleaf solves this by shipping a same-origin HTTP reverse proxy inside the DSH host process: all traffic flows through /overleaf-proxy/ to your configured upstream, framing headers are stripped, and a bridge script is injected. Inside the fourth session-page tab the full Overleaf experience—file-tree editing, side-by-side LaTeX source and PDF preview, Recompile—works exactly as it does in a standalone browser, while the native DSH composer stays below it for quoting, instructing, and context.

Beyond the editor, the plugin adds a three-tool assist panel. ai-insert lets you describe a change in natural language; the agent writes the LaTeX, the output is auto-captured into a review box, and on confirmation it is inserted at the editor caret via CodeMirror APIs. selection-ai works on any highlighted span: ask the agent to explain or rewrite, review the replacement, then write it back (with source and selection drift checks on by default). compile-fix reads the error and warning entries from the latest Recompile log and sends them to the agent for line-by-line fixes. Round-trip .bib detection and sync, bidirectional .tex synchronization (Overleaf-to-local by default; reverse whole-document replacement requires an explicit confirmation plus revision and snapshot checks), document outline navigation, and session login management round out the feature set.

This plugin is built for researchers and students who draft or refine LaTeX documents inside a DSH conversation and want the editor, compiler, and AI assistant in a single surface—no more tab-hopping between Overleaf and the DSH composer. Any public-cloud or self-hosted Overleaf instance is supported; switch the upstream in one settings field and the proxy target hot-swaps without a service restart.
