dsh-git-chain

A long, linear list of commits rarely makes branch divergence, merge convergence, or the first-parent chain obvious at a glance. dsh-git-chain renders repository history as a continuous SVG lane graph where each branch gets its own visual channel, merge nodes and branch forks are instantly recognizable, and a first-parent mode focuses on the current HEAD mainline while preserving merge metadata.

While browsing history you can click any commit to see author, parent links, and a file-level change summary, then load a unified diff with added and removed line counts on demand. A one-click local branch switch is built into the same sidebar, guarded by automatic checks for conflicts, in-progress Git operations, other worktrees, and potential file overwrites so your working tree stays safe. Instant filtering by subject, author, ref, or commit OID combined with virtual scrolling keeps even thousands of commits fluid to navigate.

If you code daily inside DeepSeek Harness Desktop and find yourself constantly reviewing commit topology, comparing changes, or switching branches safely, dsh-git-chain is the sidebar companion designed for exactly that workflow.
