The "performance" topic on GitHub groups 10 open-source projects in the DeepSeek Harness (DSH) ecosystem, led by dsh-fast with 6 GitHub stars. dsh-fast — Read-only performance diagnostics for DeepSeek Harness: session load/restore timing, spill-hit counts, compaction count and trigger, context-injection volume (AGENTS. Every project here is indexed by DSH Universe with live GitHub data — stars, activity and install status — so you can compare and install directly.
Read-only performance diagnostics for DeepSeek Harness: session load/restore timing, spill-hit counts, compaction count and trigger, context-injection volume (AGENTS.md/skills/tool-schema token share), and LLM cache hit rate — surfaced via /fast, persisted as reconstructable session events with async sampling off the model path.
Curate tool output before it enters the model's context — keep error/warning lines and head/tail, spill the full text with a pointer. ~24x smaller model view, measured. For DeepSeek Harness.
DSH plugin: adds transparent gzip compression to DeepSeek Harness Web responses, speeding up session-record loading over remote access (measured single page 12.6MB→1.06MB). Zero-dep gzip middleware for DSH web.
