sleepinginsummer/dsh-rtk-optimizer

Project Overview项目介绍

This is a native DSH plugin built exclusively for DeepSeek Harness, ported from the pi-rtk-optimizer project from the Pi Coding Agent ecosystem. It works as a host interceptor that adds two key features: RTK command rewrite suggestions and tool output compaction for existing tool calls. To install the plugin, run the command dsh plugin --profile <name> add dsh-rtk-optimizer in your terminal, then restart DSH to activate it across all your sessions. It does not register new model tools, instead it hooks into existing tool events to work globally for all bash, grep, and read calls.

When an LLM calls a bash command, the plugin checks if you have the RTK binary installed locally on your machine. By default, it runs in suggest mode, which does not interrupt the original command and only appends the RTK rewrite suggestion to the end of the output. You can switch to rewrite mode via the /rtk command, which will deny the original call, return the rewritten command in the error feedback, and let the model retry with the improved command. The output compaction feature processes successful outputs from bash, grep, and read calls with a configurable pipeline to reduce redundant text.

The output compaction pipeline includes multiple steps: stripping ANSI color codes, compressing Git output, aggregating test results, filtering build logs, grouping grep search results, and truncating overly long output. The plugin tracks the number of characters saved by compaction across all calls, which you can view with the /rtk stats command. If RTK is not installed on your local machine, the plugin leaves all original commands unchanged and caches the detection result for 60 seconds to avoid repeated checks. Development of the plugin includes 20 test cases covering all core compaction and functionality features.

本项目是专为DeepSeek Harness(DSH)开发的原生插件,作为宿主拦截器工作,移植自Pi Coding Agent生态的pi-rtk-optimizer,核心提供RTK命令改写建议与工具输出压缩两大功能。插件不注册新模型工具,而是挂载到两个工具事件上,对所有会话的bash、grep、read调用全局生效,同时提供/rtk命令供用户查看运行状态与配置。

当模型调用bash命令时,如果用户本地已经安装RTK二进制工具,插件可在两种模式下工作:默认是suggest模式,不打断原命令执行,仅在输出结果末尾附上RTK给出的改写建议;手动开启rewrite模式后会拦截原调用,返回改写后的命令让模型重试。输出压缩功能可对bash、grep、read调用的成功输出按规则压缩,减少不必要的冗余内容。

本插件可通过dsh plugin命令一键安装,安装后重启DSH即可全局生效。它支持ANSI码剥离、Git输出压缩、测试结果聚合、构建日志过滤、搜索结果分组、超长输出智能截断等多个压缩步骤,还能统计每次压缩节省的字符总数。插件依赖本地安装RTK二进制工具,若未安装则原命令正常执行,不会中断现有工作流。

dsh-rtk-optimizer

npm version

RTK 命令改写建议 + 工具输出压缩——DSH 插件(Host 拦截器),移植自 Pi Coding Agent 生态的 pi-rtk-optimizer。

不注册模型工具:它挂在两个工具事件上,全局生效(对所有会话的 bash/grep/read 调用),并提供 /rtk 命令查看状态。

功能

1. RTK 命令改写(tools/pre-execute)

模型调用 bash 时,若本机装有 rtk 二进制(rtk rewrite <command>),插件:

  • mode: rewrite(默认关闭,需 /rtk 切换)——deny 一次该调用,并在错误反馈中给出改写后的命令;模型重试时用新命令(rtk 幂等,不会循环;同一命令 30s 内只 deny 一次)。
  • mode: suggest(默认)——不打断调用,在结果末尾附注 [rtk-optimizer] rtk suggests: ...。

DSH 工具参数在分发管道中不可变(tools/execute 只能改 exec.signal),所以"自动改写"以 deny+反馈的形式实现——这是架构允许下最接近自动改写的语义。 rtk 未安装时:原命令原样执行(guardWhenRtkMissing: true),探测结果缓存 60s,不重复 probe。

2. 输出压缩(tools/post-execute)

对成功返回的 bash/grep/read 文本输出按配置走压缩管线(可单独开关):

阶段 说明
ANSI 剥离 移除 CSI/OSC 颜色控制序列
Git 压缩 git status --short 行汇总为一行统计;40 位 commit hash 缩短为 7 位
测试聚合 保留 Tests: N passed, M failed 总结与失败行,折叠其余(jest/mocha/vitest/go test/pytest 命令触发)
构建过滤 只保留 error/warning 行 + 汇总统计(build/tsc/make/npm 等命令触发)
搜索分组 path:line:content 行按文件分组(grep 工具输出)
智能截断 超 maxOutputChars(默认 30000)时保留头 + 尾,中间打截断标记

统计每个调用的节省字符数,/rtk stats 可查。

3. /rtk 命令

/rtk [show|verify|stats|clear-stats|reset|set|help]——配置与运行状态、rtk 二进制探测、压缩节省量统计。

子命令 说明
show 当前配置 + rtk 二进制状态 + 统计
verify 检查 rtk 二进制是否可用(探测结果缓存 60s)
stats / clear-stats 查看 / 重置压缩节省量统计
set <key> <value> 运行时切换:mode(suggest|rewrite)、enabled、guardWhenRtkMissing、readCompaction
reset 恢复默认配置

实现适配:rtk 0.43 对成功改写返回退出码 3(非文档所述 0),插件同时接受 0 与 3;不支持的命令退出 1 且无输出,命令原样放行。

安装

dsh plugin --profile <name> add dsh-rtk-optimizer

安装后重启 DSH,压缩与改写对全部会话的 bash/grep/read 调用生效(/rtk 命令可查状态与统计)。

开发
