dsh-agent-context

Agent Context

Integrated context governance plugin: /context command + ctx.contextMeter service + pruning tools (prune_candidates/apply/expand/guard/stats) + two notification channels (context reminders / compression alerts, with state persisted to disk for deduplication across restarts)

The plugin will be installed here. Keep web if you are unsure.

dsh-agent-context — 上下文管理插件

DSH（DeepSeek Harness）插件：会话上下文的注入与管理。

功能特性

  • 上下文注入：按需向会话请求注入上下文内容
  • 会话感知：与 agent 会话模型联动
  • /context 命令：人类可读的上下文占用报告（占用、花费、组成）
  • ctx.contextMeter 服务：结构化上下文快照（供其他插件消费）
  • 剪枝工具：prune_candidates / prune_apply / prune_guard / prune_stats / expand
  • 压缩失败守望（v0.2.1）：压缩失败不再静默

压缩失败守望（v0.2.1）

为什么需要它。 压缩插件的「会话忙」路径是 fire-and-forget——工具返回「压缩已启动」， 真正的提交发生在之后（模型输出 checkpoint 时），此时抛出的错误回不到工具调用方， 最终只落一行 logger.warn。实测代价：10 次压缩全部失败、跨 2 天无人知晓，直到从 「流程跑完了但上下文没减少」这个症状才发现。durable ≠ visible——失败记录在会话事件流里， 但没有机制去读它。

它做什么。 在每轮结束（turn/end）时，从会话尾部有界回溯，找出最近一次 compaction/end；若它携带 error，就向会话投递一条【压缩告警】，附带失败原因与事件 seq， 供下一步取证。

它不做什么（避免狼来了）。 最近一次压缩成功即视为健康，不报历史旧错误；同一失败事件 只提醒一次；只看尾部固定窗口，不扫全库；纯读取 + 字符串拼装，任何异常静默返回—— 提醒机制的故障绝不影响会话与压缩本身。
