vn-harness

Plugin pack for DeepSeek Harness.

Everything ships as standard dsh bundles. The plugins are plain JavaScript, and the launchers run on Windows, macOS and Linux — the Windows half is PowerShell, the macOS/Linux half is plain POSIX shell.

Plugins (all alpha)

Each package's own README is the reference for what it does, why it is built that way and what it touches; the table below is the map.

The pack used to ship its own Files panel (dsh-files, earlier dsh-focus) with a private dock and header capsules; that was retired when the harness grew a real right Sidebar. Now the pack goes one step further and owns the bar itself by forking it — see packages/dsh-rightbar/README.md and the scripts/sync-vendored.ps1 re-sync path. The same fork-and-disable scheme owns the file-manager half of Open In… (dsh-open-in-app).

The pack's master is a bundle of its own, dsh-vn-master, and it is deliberately blank: the bundle layer plus one no-op row, with no browser half, no service and no inject edge. So the right bar keeps only bar responsibilities, and the master — installed last — is where pack-wide patches go.

Quick start

Three commands take you from a fresh clone to a running app. Everything else in this repository is documentation.

What you need: Node.js 22 or newer, with npm/npx. That is the whole requirement. Chrome is optional — the launcher falls back to your default browser. Two features have optional extras: the History tab needs git on PATH, and TikZ diagrams need a TeX engine (pdflatex, xelatex or lualatex). Without them, the rest of the pack works unchanged.

Windows uses the .bat files, macOS/Linux the .sh ones — and the Unix side never needs PowerShell.

:: Windows - install/uninstall are double-click friendly; run is one PowerShell file
install.bat                  :: installs into the web profile (the only target)
powershell -NoProfile -ExecutionPolicy Bypass -File run.ps1
                             :: starts the harness and opens it in Chrome
uninstall.bat                :: removes the pack

# macOS / Linux - from the repo root
./install.sh                 # the web profile (the only target)
./run.sh                     # start the harness and open it in Chrome
./uninstall.sh               # remove the pack

The run launcher keeps the harness in the foreground of that terminal, so the app's own output — including the dsh web: http://127.0.0.1:3080/?token=… line — stays visible and Ctrl+C stops it. Flags pass straight through:

• -Port 3099 when port 3080 is already taken,
• -DefaultBrowser to skip Chrome,
• -NoBrowser to start the server without opening a browser at all.

The URL is opened only when it names a loopback address, and the launch token is never written to a file — both rules are explained in SECURITY.md.

Install flags: -Force re-adds bundles even when the versions match. -Plugin / -DshHome / -ProfileName / -DshVersion / -Target web|cli behave as documented in docs/INSTALL.md, which also has the no-script path:

:: Windows (direct)
powershell -NoProfile -ExecutionPolicy Bypass -File scripts/install-all.ps1 -Force

# macOS / Linux (direct)
sh scripts/install-all.sh -Force

Both installer halves do the same work, and re-running them is safe:

1. pin the dsh version from .dsh-version.json and run everything through npx @deepseek-ai/dsh@<pinned>,
2. reuse a system pnpm when it is new enough for the profile, else bootstrap a private copy under ./tools (no admin rights, nothing global),
3. resolve the web profile ($DSH_HOME/profiles/web, $DSH_HOME = env var or ~/.dsh),
4. prune retired bundle names (dsh-focus, dsh-files — the pack's own Files panel, now shipped by the harness itself) so an upgrade cannot double-mount,
5. run dsh plugin --profile web add <bundle> for every package under packages/ (bundles already at the repo version are skipped unless -Force),
6. copy the skills a bundle ships (packages/<bundle>/skills/<name>/SKILL.md) into $DSH_HOME/skills, where the harness' own filesystem skill provider reads them. Every folder the installer creates carries a marker file, so a person's own skill of the same name is never overwritten and uninstall only removes what it wrote,
7. print next steps. Neither half touches API keys — add yours in Settings → Models.

To remove the pack, run uninstall.bat (Windows) or ./uninstall.sh (macOS/Linux); both take the same -Plugin / -DshHome / -ProfileName switches. Removing a bundle also removes its patch layer.

Notes

• Alpha software, on purpose. Every package ships as -alpha.N, and the pack is built and tested against the one harness line pinned in .dsh-version.json (0.1.5-rc.1) — never against latest. dsh-rightbar, dsh-rightbar-files and dsh-open-in-app are forks of that line's client bundles, so a pin bump is a deliberate step: bump the pin, run scripts/sync-vendored.ps1 to move the forks forward, then re-verify (see packages/dsh-rightbar/README.md). dsh-open-in-app is the one fork that is not byte-for-byte — its documented patches live in sync-vendored.ps1. sync-vendored.ps1 is maintainer tooling, and the one script in this repo that wants PowerShell 7 (pwsh) on macOS/Linux; the installers never do.
• Plain JavaScript, no build step. The UI halves are hand-written module-table bundles, so the edit → restart loop stays instant. A few files are generated and never hand-edited: the three forked bundles (dsh-rightbar/lib/client.js, dsh-rightbar-files/lib/client.js, dsh-open-in-app/lib/client.js) and the engines the pack vendors and serves itself — dsh-editor's CodeMirror 6, dsh-diagrams' Mermaid (rebuilt by packages/dsh-diagrams/vendor/build.mjs) and dsh-terminal's xterm.js with its stylesheet.
• Making a change visible. After editing a client.js, restart npx @deepseek-ai/dsh web and hard-refresh the browser (Ctrl+F5). The web profile installs every bundle as a live link into this repo, so the edit is already "installed" — but the bundle is read once, at app boot. A plain install.bat / ./install.sh re-syncs every bundle whose version in this repo changed (bump package.json + .dsh-version.json first); -Force re-adds regardless, which is what a changed package set needs. There is no hot reload unless a pnpm run dev:web watcher from the harness repo is running.
• Running it. run.ps1 / ./run.sh start the pinned dsh web with --no-open, read the dsh web: http://127.0.0.1:<port>/?token=<token> line the app prints once it is listening, and open that URL in Chrome (the default browser is the fallback). A URL that does not name a loopback address is refused instead of opened, and the launch token — a live credential for the running process — is only ever held in memory: never written to a file, never passed through a shell. SECURITY.md describes the whole access model and how to lock the app down.
• Where to read more. docs/INSTALL.md has the manual install path and troubleshooting, docs/COMPATIBILITY.md the supported harness line, and each package's own README the details of that plugin.

Security & license

• MIT — see LICENSE. Plugins are authored by vecnode.
• Security policy (supported line, private reporting, hardening expectations): SECURITY.md. This pack never touches API keys and never patches DeepSeek core files: it adds its own rows and (for the right bar) disables the shipped rows, then supplies its own copied bundles.
