dsh-session-handoff

Long sessions hitting context limits, repeated auto-compaction, and lost progress on every new session — these are the daily headaches of heavy DeepSeek Harness users. dsh-session-handoff was built to solve exactly that: a zero-dependency core with no build step, packaging the full workflow from safe handoff to proactive compaction into independently callable tools.

Five modules cover the ground. Handoff parses the current session into a structured Markdown document that a fresh session can load and continue from seamlessly; ACP compresses consumed history before the window fills, keeping the original text as a searchable hidden layer; Session management offers trash-style archive, restore, and permanent delete with recoverable mistakes; Model Routes let a single model id switch freely across official API, Volcano Ark, custom endpoints, and vision-toolkit wrappers, with automatic failover on quota or timeout errors; the Web GUI maps all of this into a drag-to-reorder panel, slider controls, and one-click export buttons — no command memorization needed.

It is best suited for users running long-horizon agent workflows, juggling parallel sessions, or sharing one model across multiple vendors on Harness, and for developers who want to fine-tune compaction thresholds without editing YAML. If you only have short conversations, the payoff is limited; but once a session runs into tens of thousands of lines, it quickly becomes essential.
