@weibaohui/context-razor

上下文剃刀：把当前会话上下文逐条列出来——角色、预览、≈token（cl100k_base 估算，与技能市场同词表）——超阈值标红，勾选后精确裁剪。压缩不知道裁了什么，剃刀让你自己挑。

上下文剃刀：逐条 token + 精确裁剪

核心功能

  • 逐条列出：当前会话模型可见的每条上下文（用户/助手/工具结果）按序排列，带预览、字符数与 ≈token 估算，点 ⋯ 查看全文与真实 usage
  • 占比标注：每条的 token 徽章同时显示其占全部上下文的百分比（如 ≈5728 · 15%），一眼看出谁是上下文大头
  • 类型筛选：按类型一键过滤——用户 / 注入 / 助手，以及各工具名（bash、skill、read、edit…按会话实际出现的动态生成）。多选 toggle，与 token 量级筛选正交叠加
  • 超阈值标红：可调阈值（默认 500 token，本地记忆），超限条目红色高亮；「只看超阈值」过滤 + 「token 高→低」排序，大头一眼可见
  • 精确裁剪：勾选任意条目一键删除——连续段自动合并处理。删除走宿主 surface replace 协议（与官方 compaction 同款机制），不经 LLM 总结，删了什么、删了多少完全由你决定。每行尾部带 ✕ 快捷按钮，单条直接删与勾选后多选批量删走同一确认弹窗
  • 不重排：本插件不会改变上下文条目顺序，只会剔除选中条目；「token 高→低」排序仅影响页面显示，模型可见顺序始终由会话 surface 决定
  • 安全护栏：会话运行中禁止裁剪（等当前回合结束）；每次替换附带一条 notice 标记消息，模型知道这段历史被你移除了，需要时会主动向你确认
  • 非破坏：append-only 日志保留全部痕迹（宿主机制如此）。「删除」= 从模型视野与界面投影中移除

安装

dsh plugin --profile web add @weibaohui/context-razor -w

装完重启 dsh web 即生效。入口：打开会话 → 顶部「上下文剃刀」标签（Hermes Loop 右侧），自动锁定当前会话。

删除的实现方式

dsh 会话是 append-only 事件日志（深冻结 + zstd 校验），物理删除不存在也不必要。本插件的裁剪 = 仿官方 dsh-compaction-tool-result-pruner 协议：对每个连续段追加一条 compaction/prune 计价事件 + 一条带 surfaceOp: { op:'replace', startSeq, endSeq } 的 notice 标记消息（宿主 isReplaceOp 严格校验恰好三键 op/startSeq/endSeq，0.4.10 修复，issue #6；sourceEventSeqs 覆盖全部被影子化节点）。被删节点从此不进 deriveMessages()——模型看不到、UI 不再渲染、token 不再计入上下文，而日志留痕可审计。

版本兼容性

本插件与 DeepSeek Harness（@deepseek-ai/dsh）的版本对应关系：

插件版本适配 dsh 版本备注
0.4.100.2.1-rc.2修复 issue #6：裁剪 surfaceOp 改用宿主 isReplaceOp 的严格键名 { op, startSeq, endSeq }——旧写法 start/end 因 hasOwn('startSeq') 为 false 直接抛 invalid replace surfaceOp，整次裁剪中断（0.4.8/0.4.9 均中招）；已在 @deepseek-ai/dsh@0.2.1-rc.2 下核对 dsh-session 的 isReplaceOp 源码，单测复刻同款严格键名校验（23 项通过）
0.4.50.1.7-rc.2已在 @deepseek-ai/dsh@0.1.7-rc.2 下验证运行

发版约定：每次发布新版本时，请在上表追加一行，记录该插件版本实际验证所用的 @deepseek-ai/dsh 版本。package.json 的 engines.dsh 声明最低支持版本；本表记录实际验证版本，二者配合使用。
