This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

轨迹重现插件：把轨迹重放粒度细化到具体某条 assistant 消息 / 工具调用（记录级），提供原轨迹 vs 新执行对比、step 级单步门控与执行台账。纯插件实现，不修改 harness。

![Trajectory Replay](docs/screenshot.png)

架构

host 半部（src/index.ts，进程内 ReplayRegistry）

  • POST /api/replay/start —— 按 kind: turn|message|tool 计算切点 → 构造 seed（记录级以合成 turn/end {interrupted} 收口 + plugin-source context 载体续跑）→ 创建 origin:'subagent' 子会话
  • POST /api/replay/checkpoints —— 从完整会话日志派生全量可重放点（turn 级 + 记录级，不受浏览器分页限制）
  • POST /api/replay/control / discard / promote —— 单步继续/撤销/停止、清理、导出为工作区会话
  • agent/request 瀑布监听 —— step 模式门控

client 半部（src/client/）

  • replay-state.ts —— ReplayController 状态机 + 会话快照源（后台 open 子会话窗口）
  • ReplayView.tsx —— 按 turn 折叠的 checkpoint 选择器、运行控制、执行台账、两侧对比面板
  • TrajectoryTable.tsx / TrajectoryView.tsx —— 轨迹表格内 turn 级与记录级重放按钮（一行最多一个 ▶）
  • replay-checkpoints.ts —— host 全量 checkpoint 拉取

安装

一键安装

bash scripts/install.sh            # 或 bash scripts/install.sh <profile名>

脚本执行：① tsc 构建 host；② tsdown 构建 client；③ 在目标 profile 建立 node_modules junction、写入 package.json 的 link: 依赖与 bundles 条目、禁用官方 ui-trajectory 条目（全部幂等）。

  • 重启 dsh 生效；运行中的 harness 免重启：dev_inject_plugin <本目录>。
  • 装配后刷新浏览器页面使用。

构建

npm install
bash scripts/build.sh   # host（需 DSH_CHECKOUT）
npm run build:client    # client（tsdown）
