What it does

AgentFrame compaction backend for DeepSeek Harness: semantic+physical KV compression (35.6x)

✅
Our take
Works — verified, early-stage project

AgentFrame compaction backend for DeepSeek Harness: semantic+physical KV compression (35.6x) It installs cleanly and boots without issues in our testing. It's early-stage but functional.

“Verified” means our automated CI actually ran dsh plugin add in a clean profile and it booted — nothing more. Feature descriptions and version compatibility are the author’s claims. This is not a security audit and not an endorsement of third-party code.

README

dsh-compaction-agentframe

AgentFrame 压缩后端插件 —— 把 DeepSeek Harness 的默认 LLM 摘要压缩替换为
语义 + 物理双轨压缩(28.4x KV 压缩思路)。

为什么替换默认压缩

默认 compaction-basic 用 LLM 摘要(有损总结旧对话),每次压缩都要一次
LLM 调用,且摘要可能丢细节。

AgentFrame 的思路:

  • 语义轨:MemoryDirector 判断哪些 token 值得保留(去闲聊、留关键)
  • 物理轨:吸收式 MLA + INT4 量化(270KB→7.6KB/token,28.4x)
  • 效果:保留关键信息 + 大幅省 token + 不额外调用 LLM

使用

在 profile 的 cordis.patch.yml 中把 compaction-basic 替换为:

- id: compaction-agentframe
  name: '@deepseek-ai/dsh-compaction-agentframe'
  config:
    semantic: true
    retainRatio: 0.2
    physical: true

配置

字段 默认 说明
semantic true 语义压缩(保留高信息行)
retainRatio 0.2 压缩后保留比例
physical true 物理压缩记账(bytes/token)
bytesPerToken 7776 INT4 压缩后每 token 字节
auto true 自动压缩

实现

继承 CompactionEngine(compaction seam),实现三个抽象方法:

  • compactIfNeeded — 自动压力触发
  • compactNow — 手动 /compact 命令
  • compactRegion — 指定范围压缩

保持 dsh 的 surface/事件/持久化契约(compaction/start → replace → compaction/end),
只替换"如何压缩"。

Install

🧩 Let your agent install it (recommended)

Install the catalog once, then DeepSeek Harness can find and install any plugin from this site automatically:

dsh plugin add dshbase-catalog

Then say "install dsh-compaction for me" — your agent finds it in the directory and installs it. Docs: dshbase-catalog · verified packs.

This plugin is GitHub source (not published to npm) — install it straight from the repo:

Web profile:

dsh plugin --profile web add github:ljsysfurryACE/dsh-compaction

Headless (CLI) profile:

dsh plugin --profile headless add github:ljsysfurryACE/dsh-compaction

Test report

Verified: L1 install + L2 load + L3 runtime from GitHub source on dsh 0.1.0-rc.6.

Security: not yet scanned — our daily static scan will cover it shortly.
