dsh-drop-md

Working with Markdown documents and skill packages in DeepSeek Harness (DSH) often means breaking flow to copy-paste, hunt for insertion points, and manually verify frontmatter. dsh-drop-md collapses all of that into a single drag: drop a .md, .txt, or .markdown file from your file manager onto the area above the DSH composer, and small files are inlined into the draft instantly while large files are saved to the workspace with an @ reference. No window switching, no path memorization.

For SKILL.md packages, the plugin validates the frontmatter (name in kebab-case, description required), shows a confirmation dialog with the parsed metadata, and installs with one click to either the project .dsh/skills/ or the user-level skills directory. The DSH skill watcher picks it up immediately. Holding Shift during the drag forces full-text inline insertion for any file up to 512 KB, covering edge cases where a complete read is needed.

The interaction stays out of the way: nothing renders in the composer area until a file is dragged in, the drop zone appears only on hover, and result chips fade out after roughly four seconds. All colors use official DSH theme tokens with automatic light and dark mode support. Security is by design: the browser half communicates with the host half over a same-origin HTTP route that enforces the app trust checks (loopback authority, cross-site rejection, Origin matching), with no secrets, no telemetry, and no external network calls.

Built for developers and content creators who write Markdown daily in DSH, manage skill packages, or want the lowest-friction way to bring files into the workspace.
