dsh-code-impact

English | 中文

dsh-code-impact is an independent DeepSeek Harness plugin that performs one read-only TypeScript/JavaScript change-impact analysis. It compares a concrete Git change, builds a temporary reverse module graph, and returns changed declarations, affected files, propagation paths, evidence locations, and ranked test candidates. Version 0.2.0 understands JSONC project configuration, tsconfig.json/jsconfig.json, extends, project references, path aliases, package exports/imports, and reuses unchanged snapshot content within one invocation. It does not maintain a repository index.

dsh-code-impact 是一个独立的 DeepSeek Harness 社区插件，用于对一次具体的 TS/JS Git 变更执行只读影响分析。它临时构建反向模块依赖图，返回变更声明、受影响文件、完整传播路径、文件行号证据和排序后的候选测试。0.2.0 支持 JSONC 项目配置、tsconfig.json/jsconfig.json、extends、项目引用、路径别名、package exports/imports，并在一次调用内复用未变化快照内容。不维护长期代码地图。

Install / 安装

npm install dsh-code-impact
dsh plugin --profile demo add dsh-code-impact
dsh --profile demo --dump-config

The package exports cordis.patch.yml through the dsh.bundle.patch manifest field. The patch expects the profile to provide the DSH tools, fs, and subprocess services. It does not install a Git provider or a filesystem provider.

该包通过 dsh.bundle.patch 暴露 cordis.patch.yml。补丁要求 profile 已提供 DSH 的 tools、fs 和 subprocess 服务，不会安装 Git provider 或文件系统 provider。

Tool calls / 工具调用

The registered tool is code_impact。

已注册的工具名为 code_impact。

{"mode":"workspace"}

Compares HEAD with the current working tree, including staged changes, unstaged changes, and untracked non-ignored files.

比较 HEAD 与当前工作树，包含已暂存、未暂存和未被忽略的未跟踪文件。

{"mode":"staged"}

Compares HEAD with the Git index。

比较 HEAD 与 Git index。

{"mode":"refs","base_ref":"origin/main","head_ref":"feature/payment"}

Validates both refs and compares the merge-base to head_ref, which matches the usual pull-request comparison semantics. base_ref and head_ref are rejected in the other modes; an invalid ref never silently falls back to another revision.
