dsh-compaction-tune

The stock compaction policy in DeepSeek Harness (@deepseek-ai/dsh-compaction-basic) ships with a static ratio pinned in the plugin YAML (default 0.8) and offers no in-conversation way to tweak it. dsh-compaction-tune drops a live chip into the lower-right of the composer, letting you set a compression trigger as a percentage (30–80%) or an absolute token count (64k–832k). The value is written to your local settings file and takes effect on the very next agent step—no restart required.

Under the hood the chip cooperates with the official compaction backend: once consumed tokens cross your threshold while still below the 80% safety cap, the plugin calls compactIfNeeded to compress proactively. If your threshold sits at the 80% ceiling, the official listener remains the sole trigger. When the optional anchored backend is loaded, this plugin simply exposes its policy service and registers no second trigger, preventing double compaction. Child sessions such as sidebar branches never inherit the main-chat threshold and retain the backend default.

Ideal for DeepSeek Harness users who juggle long and short context tasks, want per-task fine-grained control over when compaction fires, and prefer not to hand-edit the official plugin YAML. Note: installing this plugin alone does not add a compaction engine; your web profile must already ship compaction-basic or a compatible backend for the chip to actually trigger a compression pass.
