dsh-purge

Version 1.3.6

DeepSeek Harness jailbreak (破甲): every model can jailbreak; swap prompts per model. Default prompt for Chinese models — 小码酱. Please star ⭐

English | 中文

Aligned with dsh 0.1.5-rc.1 (Node.js ≥18; the no-flash import hooks for Windows require Node ≥22 registerHooks, and older Node versions still get file-level windowsHide patches). On other versions, unmatched originals stay pending or are skipped. Nothing is rewritten blindly.

It also accepts the 0.1.2 community dsh-persona text field and dsh-mnemon v0 session summary. After installing, you still need to Apply and restart.

🛡️ Why a local harness purge

Models now run inside a local Agent / Harness. Prompts, approval gates, sandbox policies, and session migration all rewrite behavior at runtime. Asking "will the model answer" isn't enough if the host layer kills a legitimate eval request first.

1. Map the host guardrails, not just the model. Reversible patches on the installed @deepseek-ai/* packages reveal which refusals come from the model and which come from default copy, approval ladders, or session-format checks.
2. Keep official capabilities; drop refusal locks. No second invented identity. Persona is whatever you put in prompt-inject.md.
3. Survive upgrades. Patches are re-applied after npm overwrites node_modules. Unmatched originals are skipped so a 0.1.5 tree isn't smashed blindly.

This is a local Harness plugin. It is not a public scanner and not an attack kit for third-party sites.

⚡ Install

Web and desktop install the same plugin into different profiles. After installing, you must fully quit and restart DeepSeek Harness so the Rules card appears. Then Apply — adding the bundle does not patch the @deepseek-ai packages by itself.

🌐 Plugin hub: DeepSeek Harness Hub

Method 1: Hand this to an AI agent (fastest)

Paste this README (or the block below) into a local coding agent and let it install and operate.

dsh plugin --profile web add https://github.com/YuJunZhiXue/dsh-purge/archive/refs/heads/master.zip

dsh plugin --profile default add https://github.com/YuJunZhiXue/dsh-purge/archive/refs/heads/master.zip

git clone https://github.com/YuJunZhiXue/dsh-purge.git
cd dsh-purge
dsh plugin --profile web add .
# dsh plugin --profile default add .

# Restore on the settings page first if patches must be undone, then:
dsh plugin --profile web remove dsh-purge
dsh plugin --profile default remove dsh-purge

Method 2: dsh:// one-click (desktop, no CLI)

If the official DeepSeek Harness desktop client (EXE) is installed, the button below opens a system URI scheme and loads the plugin.

</a>

dsh://plugin/install parameters:

Method 3: Official CLI (dsh plugin add)

git clone https://github.com/YuJunZhiXue/dsh-purge.git
cd dsh-purge

# Web
dsh plugin --profile web add .

# Desktop
dsh plugin --profile default add .

Or skip cloning and pass the zip:

dsh plugin --profile web add https://github.com/YuJunZhiXue/dsh-purge/archive/refs/heads/master.zip
dsh plugin --profile default add https://github.com/YuJunZhiXue/dsh-purge/archive/refs/heads/master.zip

Run both if you use Web and desktop. Then restart, then Apply on the settings page or /purge apply in chat.

Method 4: Manual install

Use this when dsh is not on PATH or you don't want dsh plugin add. Do not delete existing bundles.

1. Find the Harness home ($DSH_HOME)

Web = profiles/web. Desktop = profiles/default (or whatever profile directory the desktop client actually uses).

2. Put this repo under plugins

git clone https://github.com/YuJunZhiXue/dsh-purge.git "$DSH_HOME/plugins/dsh-purge"

Or copy the tree to $DSH_HOME/plugins/dsh-purge (the folder name must be dsh-purge).

3. Edit that profile's package.json

• Web: $DSH_HOME/profiles/web/package.json
• Desktop: $DSH_HOME/profiles/default/package.json

Add to dependencies (keep the other deps):

"dsh-purge": "file:../../plugins/dsh-purge"

Append "dsh-purge" at the end of dsh.profile.bundles:

• Web: keep @deepseek-ai/dsh-web-app, only append this plugin
• Desktop: keep @deepseek-ai/dsh-base (and the rest), only append this plugin

Sketch (keep every other field from the file on disk):

{
  "dependencies": {
    "dsh-purge": "file:../../plugins/dsh-purge"
  },
  "dsh": {
    "profile": {
      "bundles": [
        "@deepseek-ai/dsh-base",
        "@deepseek-ai/dsh-web-app",
        "dsh-purge"
      ]
    }
  }
}

If the desktop profile has no dsh-web-app row, don't add one; just make sure "dsh-purge" is in bundles.

4. Install deps

cd "$DSH_HOME/profiles/web"
pnpm install

cd "$DSH_HOME/profiles/default"
pnpm install

PowerShell: substitute the real path, e.g.

cd "D:\DeepSeek Harness\.dsh\profiles\web"
pnpm install

5. Restart, then apply patches

1. Fully quit DeepSeek Harness (Web process or desktop tray) and start it again.
2. Settings should show Rules. Press Ctrl+F5 if cached.
3. Click Apply, or run /purge apply, or dsh-purge --apply from the plugin dir.
4. Restart again when prompted so patched packages load in this process.

Uninstall

Click Restore on the settings page if patches must be undone, then:

dsh plugin --profile web remove dsh-purge
dsh plugin --profile default remove dsh-purge

If you installed by hand: remove dsh-purge from that profile's dependencies and bundles, run pnpm install, and restart.

Plugin config lives in cordis.patch.yml:

- insert:
    - id: dsh-purge
      name: 'dsh-purge'
      config:
        enabled: true
        autoApplyOnStart: true
        autoRevertOnMissing: false
        verbose: false
        postPromptOrder: 5100
        postPrompt: ""

postPrompt is empty by default.

What this is

dsh-purge is a settings plugin for DeepSeek Harness:

• Updates default copy, permission policy, and tool limits in the installed @deepseek-ai/* packages
• Adds a Rules card: grouped patches, Apply / Restore, session override editor, multiple rule sets
• Re-applies on startup after an npm upgrade overwrites node_modules
• No hardcoded drive letters: $DSH_HOME, .dsh next to the dsh launcher, then ~/.dsh

It does not patch the Harness source tree. Use Apply on the settings page. Identity comes only from your prompt-inject.md — the plugin does not author a second identity card.

0.1.5 notes

#20 / #21 / #28 / #29 remain optional plugin rows: skip them if those packages are absent.

Preview

The Rules card appears on the dsh web settings page. Switch Light / Ink. Patches are grouped; the count only includes items that actually applied. Rule sets sit in a list above the editor, with Enable and Delete on each row.

Runtime user files: $DSH_HOME/prompt-inject.md, $DSH_HOME/rules/. If DSH_HOME is unset, the launcher-adjacent .dsh takes precedence over ~/.dsh.

Verification

• After restarting, the Rules card appears on the settings page. Perform a hard refresh (Ctrl+F5) if the client bundle is cached.
• Click Apply, then Restart when prompted. Optional packages (liangshen / web-fetch) will show as missing/skipped and will not block the complete → restart process.
• On the first Apply, the built-in default is written to prompt-inject.md if the file does not exist; if the file already exists but is empty, it remains empty.
• /purge status prints the DSH_HOME path and the patch list.
• In version 0.1.5, selecting an existing workspace should restore the session — it should not reset to an empty workspace.
• Skipped items are expected when the target file is absent (for example, #20 / #21 without dsh-web-fetch-http).

Usage

dsh-purge --status
dsh-purge --apply
dsh-purge --revert
dsh-purge --edit

/purge status | apply | revert | edit | help
/rules list | use <id> | create <id> | delete <id> | reset | help

purge_status   purge_apply   purge_revert

Patched packages load only after a restart. Apply does not restart by itself.

Local checks

node --check lib/index.js
node --check lib/core.js
node --check client.js

How it works

Apply (on start or by hand):

patch not applied? ──no──> skip
    │yes
    ├─> backup <file>.dshpurge.bak (Desktop host-commands backups stay under `$DSH_HOME/dsh-purge/shim-backups` only)
    ├─> apply matching replacements
    ├─> override shim (dsh.cmd / dsh.ps1 / unix dsh; **skip Desktop sealed host-commands bins**)
    ├─> scrub illegal sibling `*.dshpurge.bak` inside sealed bins (Desktop validates before plugins load)
    ├─> Windows: pin hide-console + child_process import hook; patch subprocess-local / doctor / market / liangshen bash
    └─> if `prompt-inject.md` is missing, write the default (do not refill an empty file)

Override (each session):

prompt-inject.md has content? ──yes──> write it verbatim as the dsh-purge systemPrompt section
           │no
           └─> no override section

Identity (1.3.6): the plugin does not invent an “operator / LCS” second persona. Official Harness identity lines are stripped; prompt-inject.md is the identity. On 0.1.5 the inject is folded into persona-prefix so liangshen phase-1 cannot drop it.

Windows CMD silence: on Node 24, import { spawn } from "node:child_process" is not a live binding. registerHooks redirects node:child_process to a windowsHide facade; @deepseek-ai/dsh-subprocess-local also gets windowsHide: true. Doctor relaunch uses node + bin.js and does not leave a noop supervisor.cmd.

Liangshen phase-1: the default preset strips non-persona system-prompt sections. Apply / startup keeps persona, persona-prefix, persona-suffix, and inject (tool quarantine unchanged).

DSH Desktop (anywhere-labs/dsh-desktop, issue #9): host-commands/<profile>/bin is sealed — no sibling extras (including dsh.cmd.dshpurge.bak). This plugin scrubs only (no inject, no bak writes).

Prompt purge: refusal / anti-roleplay wording in minimal, official standard / code / cordis, and liangshen personas becomes executable + roleplay-allowed. No fixed role name is locked in.

Restore

• Each target is copied to <file>.dshpurge.bak before the first apply.
• Restore or /purge revert copies backups back and deletes them. With no backup, shim lines written by this plugin are stripped.
• prompt-inject.md is a user file and is kept.
• Apply is idempotent.

Path detection

1. DSH_HOME / DSH_BASE
2. .dsh next to the dsh launcher (portable install, any drive)
3. DSH Desktop app.asar.unpacked/node_modules/@deepseek-ai
4. npm prefix -g / npm root -g
5. Nested @deepseek-ai/dsh/node_modules/@deepseek-ai
6. ~/.dsh

If nothing is found, set DSH_BASE. No files are changed.

Changelog

1.3.6 (dsh 0.1.5-rc.1)

• persona schema: 0.1.5 requires prefix; #39 aliases community text so picking a workspace / opening a chat no longer wipes empty.
• history: #40 lets mnemos v0 summary migrate when form is not notice.
• identity: no plugin identity card; the dsh-purge section is verbatim prompt-inject.md.
• disclaimer: zero-tolerance, controlled-scope, license-termination, and independence clauses.
• settings UI: patch groups now include #33–#40.

1.3.5 (dsh 0.1.2-rc.1 / Node 24 Windows)

• CMD flash: fix Node 24 ESM spawn patch miss; silence subprocess-local / doctor / dshmarket / liangshen bash / doctor stub paths.
• First-turn inject: liangshen phase-1 keeps persona + inject.
• Restart: /dsh-purge/restart uses node + bin.js only, waits for the port, never pops cmd.
• Patch markers: #21 and friends accept ^0.1.2-rc.1 dependency spellings (fewer false pendings).

1.3.4

• Desktop sealed host-commands/**/bin is scrub-only — no dsh.cmd.dshpurge.bak recovery loops.

Notes

• Scope is rendered copy, defaults, and runtime logic inside local @deepseek-ai/* packages, plus override files and rule sets under the harness home.
• After an upgrade, unmatched originals surface as pattern_not_found or pending.
• Third-party plugin source repos outside @deepseek-ai are left alone (CMD silence may best-effort patch installed doctor / market / liangshen / mnemon at runtime).
• The npm package name is not published yet. Install from GitHub, the Hub, or dsh plugin add ..
