Plugin插件 Native原生 ⭐ 2 MIT Sessions & Context会话与上下文

DeepSeek Harness「压缩会话」插件:自定义 token 阈值自动压缩、一键压缩当前会话、输入框常驻按钮可开关。哦鲸鲸出品。

Project Overview项目介绍

dsh-oha-whale-compress is a session-compaction plugin built specifically for the DeepSeek Harness (DSH) runtime, shipped under the "Oha Whale" brand alongside dsh-session-manager. It exposes two UI entry points: a sidebar-bottom icon that opens the full panel, and a persistent button under the chat composer that opens a stripped-down "half" panel. The full panel exposes the compression provider and model, an auto-compress toggle, and the threshold input; the half panel collapses to just two toggles plus the trigger button. Installation is performed with dsh plugin --profile web add dsh-oha-whale-compress, and a source-tree install is supported via file:/root/dsha-oha-whale-compress. The plugin only hard-injects webServer; every other service is fetched lazily through ctx.get().

The auto-compress logic replaces DSH's window-ratio trigger (contextWindow * thresholdRatio) with an absolute token threshold defaulting to 409600 (≈400K), configurable and persisted to ~/.dsh/storages/dsh-oha-whale-compress/config.json. It neutralizes the parent's ratio check by setting thresholdRatio to a dummy 0.02, then intercepts compactIfNeeded('pressure') from the agent/pre-step hook to enforce the real cutoff. A context-overflow fallback path always fires regardless of toggles or thresholds. Manual compression is exposed via POST /oha-whale-compress/compress and goes through ctx.get('commands').execute(agent, '/compact', …); companion routes /configure, /status, and /icon (image/png, max-age=3600) round out the HTTP surface.

For auto-compress to actually use the new threshold, the preset's engine line must be swapped to dsh-oha-whale-compress/engine; the README provides an injectPreset({ presetPath, userRoot, mode: 'inject', expectedCount: 4 }) snippet that batch-updates the four presets inlined in cordis.patch.yml. The injector enforces a five-rule contract: writes only under the user root, never re-serializes YAML (preserving comments and !!js), unique-or-count check, backups first, and idempotency. Modifying src/* or the preset engine line requires restarting DSH (the loader does not watch preset files); modifying client/client.js only needs a browser refresh. The package is MIT-licensed and requires @deepseek-ai/dsh-compaction, dsh-compaction-basic, and @deepseek-ai/dsh-agent-preset to be present, with package.json exports declaring ./engine to avoid ERR_PACKAGE_PATH_NOT_EXPORTED.

dsh-oha-whale-compress 是 DeepSeek Harness(DSH)专属的会话压缩插件,归属「哦鲸鲸」家族,与 dsh-session-manager 同品牌设计。它通过侧边栏底部入口和输入框下方的常驻按钮触发,提供完整面板与减半面板两种形态:完整面板可配置压缩所用的 provider、model、自动压缩开关与阈值;减半面板仅保留开关与触发按钮。安装方式为 dsh plugin --profile web add dsh-oha-whale-compress,亦支持 file: 源挂载,仅需挂载 webServer 服务。

自动压缩的核心改进是把判定权从框架的窗口比例(contextWindow * thresholdRatio)拆出,由本插件用绝对 token 数(默认 409600,约 400K)独立触发,并在模型上下文溢出时无条件兜底。手动压缩走 POST /oha-whale-compress/compress,由插件调用 ctx.get('commands').execute(agent, '/compact', …) 触发,不直写会话日志;HTTP 路由还包括 /configure、/status、/icon。配置写入 ~/.dsh/storages/dsh-oha-whale-compress/config.json,含 autoCompress、autoThresholdTokens、dockButton 等字段。

插件依赖 @deepseek-ai/dsh-compaction、dsh-compaction-basic 与 @deepseek-ai/dsh-agent-preset,并要求 preset 内联 cordis.patch.yml 中将引擎名替换为 dsh-oha-whale-compress/engine(用 injectPreset 注入或还原)。插件不公开保留条数选项(retainTokens: 40000 写在托管块),改源码需重启 DSH,改 client 只需刷新页面。许可为 MIT。

dsh-oha-whale-compress

DeepSeek Harness 专用「压缩会话」插件(哦鲸鲸 family,与 dsh-session-manager 同品牌设计)。

功能

  • 侧边栏底部入口(挨着「会话管理」):点开完整面板。
  • 完整面板:自动压缩开关与阈值 · 输入框下方按钮开关 · 压缩用 provider / model · 一键「压缩当前会话」。
  • 自动压缩:上下文估算超过阈值时自动压一次。阈值是绝对 token 数,可开关、可改(默认 409600,即 400K)。
  • 输入框下方常驻「压缩」按钮:可一键显示 / 隐藏,关掉后输入框下方恢复干净;点它开的是减半面板。
  • 减半面板:只留两个开关 + 压缩按钮 + 结果,去掉选 API、保留条数与提示词。
  • 查看结果:展示当前会话大小(节点数 / token 数)与本次压缩的状态 / checkpoint 文本。

两个开关在完整面板与减半面板里都显示 —— 减半面板正是从输入框下方的按钮点进来的,开关得在它自己面前可调。两个开关都是拨动即存;阈值输入在失焦或回车时落盘(边打字边存会把中间态写进配置)。

自动压缩怎么工作

框架自带的自动压缩按窗口比例判定(contextWindow * thresholdRatio),表达不了「到 400K 就压」这种绝对值。本插件的做法是把判定权拆开:

  1. 注入 preset 时把父类的 thresholdRatio 让到一个哑值(0.02),父类从此不再实际把关 —— 但仍保留 2% 窗口的兜底,万一插件那条路径失效也不至于彻底失控;
  2. 子类 WhaleCompactionEngine.compactIfNeeded 接管「步进压力」这一路:
    • 未到 autoThresholdTokens → 直接返回 null,父类根本不会跑;
    • 到了阈值 → 交给父类,此时它的哑阈值必然已被越过,压缩照常发生;
  3. context-overflow(模型已经报窗口溢出)是兜底路径,不受阈值与开关管辖,一律放行。

配置落在 ~/.dsh/storages/dsh-oha-whale-compress/config.json:

字段 默认 含义
autoCompress true 自动压缩总开关
autoThresholdTokens 409600 触发线(绝对 token 数)
dockButton true 输入框下方按钮是否显示

为什么 preset 里会多出一段托管块

自动压缩保留多少由框架的 selectCompactableRange 决定 —— 那是 dsh-compaction-basic 的内部函数,既不在 @deepseek-ai/dsh-compaction 的导出里,插件也触及不到。所以面板没有、也不该有「保留多少条」这类选项(早期版本有过一个 keepN,从头到尾没接上,已删除)。实际保留量写在这段托管块里:retainTokens: 40000,即压缩后保留尾部约 40K tokens。

retainTokens 用绝对值而不是 retainRatio,一是语义直接,二是可以绕开上游「retainRatio 必须小于 thresholdRatio」的加载期校验(那条校验只在比例存在时触发)。托管块由注入器写入、由还原精确删除,不会碰你自己写的 config。

触发链路

侧边栏 / 常驻按钮 → POST /oha-whale-compress/compress {sessionId}
  → host 取 agent = ctx.get('agents').get(sessionId)
  → ctx.get('commands').execute(agent, '/compact', [], signal)
  → (command-compact 在压缩 group 里执行 compactNow,真正压缩)
  → 返回 { ok, message }

手动压缩必须走框架 ctx.get('commands').execute(agent, '/compact', ...),绝不直写会话日志。

自动压缩走的是另一条路:agent/pre-step → compactIfNeeded('pressure') → 本插件先判阈值 → 再交父类。

HTTP 路由

路由 方法 作用
/oha-whale-compress/configure GET / POST 读 / 写面板配置(provider / model / keepN / promptTemplate / prompt / autoCompress / autoThresholdTokens / dockButton)
/oha-whale-compress/status GET 当前会话大小(?sessionId=,nodes/totalTokens),非破坏性
/oha-whale-compress/compress POST {sessionId} → 触发 /compact
/oha-whale-compress/icon GET 返回 assets/icon.png(image/png,max-age=3600)
