DeepSeek Harness Plugin Introduction: context-pruner

The `context-pruner` plugin for DeepSeek Harness (DSH) is designed to address context bloat and token waste in long conversations. It uses heuristic rules to achieve deterministic processing with no model dependency, incorporating five independent context-screening mechanisms: handling outdated outputs, duplicate calls, failed calls, oversized blocks, and stale reasoning. The plugin supports configuring reserved regions and an exemption list, and it integrates seamlessly with DSH’s compression mechanism through structured audit reports. Developers can install the plugin from GitHub, via local mounting, or from a Git source, making it suitable for long-session scenarios that require token savings, such as logging and batch processing tasks.
