DeepSeek Harness for VS Code lets AI write code by hand

Key features

• After a write/edit tool call, open the target file to see VS Code's native side-by-side diff.
• The approval card shows the actual command line, working directory, and target files that will be written.
• The slash menu dynamically fetches commands registered by the Runtime for the current session (/plan, /compact, /goal, etc.) and merges them with the extension's own IDE commands.
• Right-click the current file, selection, or Git diff to explain, fix, review, or generate documentation.
• The before-image is reconstructed by replaying hunks backwards from the Session log, so it also works in non-Git repositories and Git-ignored files.
