npm-safe-forDSH re-architects the local-first npm supply-chain security engine @npm-safe/core as a DeepSeek Harness (dsh) tool plugin. AI agents can call package security scans directly inside a conversation, acting as a "check before you install" gate. The engine's full capability — checking, search, watchlist, refresh, rules, settings, and CI gate scans — is mapped to 14 dsh tools, including a background refresh_all job.

原仓库 / Original repository

• 本仓库：https://github.com/nisconder/npm-safe-forDSH
• 引擎原仓库（@npm-safe/core 源码来源，只读参考）：https://github.com/nisconder/npm-safe
• dsh 平台（DeepSeek Harness）：https://github.com/deepseek-ai/deepseek-harness

Quick Start

Requires Node.js 22.19 or later and pnpm 11.7.0 (via Corepack).

corepack enable
corepack prepare pnpm@11.7.0 --activate
pnpm install

better-sqlite3 build allowlist: better-sqlite3 is a native module and pnpm 11 blocks its build scripts by default. Allowlist is configured in pnpm-workspace.yaml (pnpm.onlyBuiltDependencies / allowBuilds) and .npmrc (only-built-dependencies[]=better-sqlite3). If still blocked, run pnpm approve-builds and select better-sqlite3.

Static verification (build first so the plugin can resolve packages/core/dist):

pnpm run build
pnpm run typecheck
pnpm run test

One-shot smoke tests (network required — hits the live npm registry):

node scripts/smoke.mjs lodash                  # prints level / score / findings
node scripts/smoke.mjs definitely-not-real-xyz # missing package → exists:false
node scripts/smoke-facade.mjs                  # watchlist / settings / ciScan

Installation

Both packages are published to the npm registry:

pnpm add @npm-safe/core-dsh           # engine
pnpm add @npm-safe/dsh-tool-npm-safe  # dsh plugin

The original @npm-safe/core belongs to the npm-safe repository and is untouched by this fork.

• Source & releases: https://github.com/nisconder/npm-safe-forDSH (latest release)
• Engine original repository (read-only reference): https://github.com/nisconder/npm-safe

Build from source

Follow the Quick Start steps above to install dependencies and build the workspace:

corepack enable
corepack prepare pnpm@11.7.0 --activate
pnpm install
pnpm run build

After building, the engine output lives in packages/core/dist and the dsh plugin output in packages/tool-npm-safe/lib. Reference them via pnpm workspace links or point your tooling at the built paths directly.

Using the plugin in a dsh runtime

DEEPSEEK_API_KEY is required. Export it in your environment or place it in a .env file at the project root before launching dsh.

pnpm dsh web --patch ./packages/tool-npm-safe/cordis.patch.yml
# Web UI: http://127.0.0.1:3080 — ask "check lodash"

# Or run headless:
pnpm dsh --profile headless "check lodash"

All dsh peer packages must belong to the same RC family (@deepseek-ai/dsh-tools / dsh-jobs-local 0.1.0-rc.x, @deepseek-ai/cordis ^4.0.1). Upgrades must stay aligned across the whole repo.

Using the engine as a library

import { NpmSafeEngine } from "@npm-safe/core-dsh";

const engine = new NpmSafeEngine();
const result = await engine.checkPackage("lodash");
console.log(result);
await engine.close();

Tools

The @npm-safe/dsh-tool-npm-safe plugin registers the following tools in a dsh session:

Tool	Purpose	Execution
check_package	Check a single package	Foreground (signal-forwarded)
check_packages	Check many packages	Foreground (rate-limited)
search_packages	Keyword search of the registry	Foreground
watch_add / watch_remove / watch_list	Watchlist management	Foreground
rules_list / rule_enable / rule_disable / rule_set_severity	Rule management	Foreground
settings_get / settings_set	Engine settings	Foreground
ci_scan	Dependency gate scan	Foreground
refresh_all	Refresh the watchlist	Background (ctx.jobs.start)

Architecture

A pnpm workspace monorepo with two packages:

npm-safe-forDSH/
├── package.json                 # Private root: pnpm@11.7.0, aggregate scripts
├── pnpm-workspace.yaml          # workspace = packages/*; better-sqlite3 allowlist
├── tsconfig.base.json           # Shared strict TS config
├── .npmrc                       # only-built-dependencies[]=better-sqlite3
├── .github/workflows/ci.yml     # Node 22.19 + 24 matrix: build → typecheck → test
├── scripts/
│   ├── smoke.mjs                # checkPackage smoke (live registry)
│   └── smoke-facade.mjs         # watchlist / settings / ciScan smoke
└── packages/
    ├── core/                    # @npm-safe/core-dsh engine (CLI/desktop/telemetry stripped)
    └── tool-npm-safe/           # @npm-safe/dsh-tool-npm-safe plugin (14 tools)

CI

.github/workflows/ci.yml runs on every push / PR: Node 22.19 and 24 matrix, Corepack enabled, pnpm install → pnpm --filter @npm-safe/core-dsh run build → pnpm run typecheck → pnpm run test.

Manual dsh Verification

End-to-end verification in dsh (Web UI / headless) is a manual step. Install the dsh CLI and configure an API key:

pnpm add -g @deepseek-ai/dsh@0.1.0-rc.6
# configure DEEPSEEK_API_KEY in a root .env file

Then verify the check_package tool:

pnpm dsh web --patch ./packages/tool-npm-safe/cordis.patch.yml
# Web UI: open http://127.0.0.1:3080 and ask "check lodash"

pnpm dsh --profile headless "check lodash"

All dsh packages are pinned to the same RC family (0.1.0-rc.6, cordis ^4.0.1). Upgrades must stay aligned across the whole repo.
