dsh-project-sources

中文 | English

Codex-style project sources for DeepSeek Harness: one workspace, many folders, each with an alias the agent can use.

A DeepSeek Harness plugin bundle that attaches extra folders to a workspace. The session keeps the workspace as its cwd; every attached folder gets the same read / write / edit / command permissions under the session's current sandbox mode, and each one carries a short alias the model can refer to.

• Project editor — “编辑项目” dialog from the session header, or the “📁 项目源文件夹” pill on the session-creation page. Add folders, rename aliases, remove them.
• Aliases in the conversation — one system-prompt section maps every alias to its absolute path, so @web/src/a.ts is unambiguous to the model.
• @ menu coverage — the shipped @ provider is single-root; this plugin contributes a companion group that searches every source (by alias, by folder name, or by absolute path).
• Source-folder skills — / finds skills under <source>/.dsh/skills, <source>/.agents/skills and <source>/skills, recursively.
• No new tools — read/glob/grep already work anywhere; write/edit/pwsh/bash are intercepted and re-rooted at the matching source.

Requirements

• DeepSeek Harness 0.2.1-rc.5 … 0.2.x (engines.dsh: ^0.2.1-rc.5)
• Node.js ≥ 20

Install

From the Web UI: Settings → Plugins → Add, then paste dsh-project-sources.

From the CLI:

dsh plugin --profile <profile> add dsh-project-sources@0.1.0

Or from a local checkout (the agent tool plugin_manager accepts a directory):

plugin_manager install_bundle   target: D:\work\dsh-project-sources

Restart the Host after a source change (the Host module is imported at boot); the browser bundle reloads on a page refresh.

Usage

Action	Where
Edit the project	“项目” button in the session header
Edit before the first message	“📁 项目源文件夹” above the composer on the session-creation page
Add a folder	Click “添加文件夹” → the OS folder chooser opens
Rename	Type in the alias field of a row
Remove	× on the row (the workspace itself cannot be removed)

Aliases must be letters/digits/./_/-, at most 48 characters; duplicates get a -2 suffix.

Where it stores data

<DSH_HOME>/storages/project-sources/<workspace-key>.json — one record per workspace, outside every agent sandbox root. Only user-driven flows write it; the agent cannot add folders to itself.

Platforms

	Windows	macOS	Linux
Folder chooser	powershell -STA + FolderBrowserDialog	osascript … choose folder	falls back to the Host picker, then the manual path field

The sandbox re-rooting, @ menu and skill discovery are platform-neutral. macOS support is implemented but not yet tested on a Mac.

Limitations

• One writable root per command. A shell run writes inside only the directory its workdir resolves to. Pass an absolute workdir inside the source; a relative one resolves against the workspace, and git -C <source> / cd <source> inside the command does not widen the root.
• The session cwd is fixed: there is no “primary folder” concept, and the workspace root stays the default working directory.
• Cannot run beside another plugin that intercepts the same tool pipeline (e.g. dsh-multi-folder).
• Background shell runs are supported through the jobs runtime, but a denial that happens after the call returns is only visible in job_output.

Development

No build step. npm test runs both suites without the DSH runtime:

node test/smoke.mjs   # config store, interception, prompt, remote API
node test/skills.mjs  # source-folder skill discovery
