Dependency-topology guard: pre-install conflict prediction and post-install detection of duplicate @deepseek-ai/dsh-* copies, version drift, and vendored core services that cause Symbol-key crashes li

English | 中文

装前预测 + 装后检测 DeepSeek Harness 的依赖拓扑冲突,防止 Symbol 键崩溃。

你装插件时崩过这个吗?

Cannot read properties of undefined (reading 'prepare')

根因是 discussion #1337:@deepseek-ai/dsh-tools 等核心包出现第二份物理副本时,JS Symbol 键(每次求值都不同)会让 ctx.tools[scheduler] 变 undefined,一次工具调度就崩,还会在会话里留下孤儿 tool_calls,之后每轮 400 INVALID_REQUEST 死锁。

本插件只做检测 + 修复建议,绝不自动修复——修复交给 dsh-undo-plugin、dsh-boot-guard 等第三方插件,保持模块化。

两个工具

dsh_depguard_predict — 装前预测(社区空白)

装新插件之前,静态拉取它的 manifest(npm 包 / github:owner/repo / 本地路径),与当前 runtime 的 @deepseek-ai/dsh-* 基准比对:

信号风险
dependencies 直接含核心包🔴 CRITICAL → NOT_RECOMMENDED(私包 = 第二份副本)
peerDependencies 版本范围与 runtime 不符🟡 WARNING → CAUTION(版本漂移风险)

预测基于静态声明,实际解析受 lockfile/nodeLinker 影响——装上后请再跑 check 确认。

dsh_depguard_check — 装后检测

扫描落盘依赖拓扑,三项检测:

检测严重度说明
duplicate-copyCRITICAL/WARNING同一核心包多份物理副本(realpath 去符号链接;同名同版本也算——Symbol 冲突本质是两次求值)
version-driftWARNING副本版本与 runtime 基准不一致
vendored-serviceCRITICAL社区插件把核心包打进自己的 node_modules(应 peerDependencies)

每条 finding 带 fix 字段,给出修复建议命令(交给第三方修复插件执行)。

安装

# npm(推荐,预构建免授权)
dsh plugin --profile web add dsh-depguard

# GitHub 源码
dsh plugin --profile web add github:DeLightor/dsh-depguard

# 本地开发
dsh plugin --profile web add ./dsh-depguard

重启后,在会话里说「检查一下我的插件依赖」或「装 X 之前预测一下冲突」即可。

测试

node --test   # 11 个用例:多副本/漂移/私包/符号链接去重/装前预测

安全声明

  • 只读:不写任何 profile 文件、不改配置、不自动跑 pnpm。
  • 零依赖:dependencies 为空;@deepseek-ai/* 一律 peerDependencies——本插件自己绝不引入第二份核心包。
  • 检测 ≠ 修复:发现问题只报告 + 给建议,动手由你或第三方回滚插件完成。

English

Predict (pre-install) and detect (post-install) dependency-topology conflicts in DeepSeek Harness to prevent Symbol-key crashes like Cannot read properties of undefined (reading 'prepare').

  • dsh_depguard_predict — fetch a target plugin's manifest and compare its dependencies/peerDependencies against your runtime baseline before installing.
  • dsh_depguard_check — scan the on-disk dependency tree for duplicate @deepseek-ai/dsh-* copies (realpath-deduped; same-name-same-version still counts — Symbol keys differ per module evaluation), version drift, and plugins vendoring core services.

Detection + fix suggestions only; remediation is left to third-party plugins (dsh-undo-plugin, dsh-boot-guard). Read-only, zero runtime dependencies, @deepseek-ai/* as peerDependencies only.
