dsh-context-checkpoint: An Automatic Checkpoint Plugin for Fixing Lost Conclusions in DeepSeek V4.1 Flash Long-Context Scenarios

The `dsh-context-checkpoint` plugin, maintained by Leafstory, is designed to address the issue in long DeepSeek V4.1 Flash conversations where the model forgets or denies earlier conclusions. It automatically summarizes and compresses the key state of the conversation and injects it at the beginning of the prompt, ensuring that the model reads the facts at the highest-attention positions without relying on model memory. Its core features include automatic checkpoint persistence, scheduled compaction, and a forced bypass mechanism, making it suitable for long-running task scenarios. After installation, DSH must be restarted. The plugin does not depend on idle windows and runs automatically when steps transition.
