dsh-toolkit

English | 中文

Plugins for DeepSeek Harness (dsh): databases, object storage, observability, browser control, AI subscriptions and a configuration center. All packages share a version and release workflow.

Package	What it adds	Where it appears
@onenightcarnival/dsh-rdb	Relational database workbench: SQLite / PostgreSQL / MySQL / GaussDB, data grid, structure, SQL editor, db_* tools	Sidebar "Database"
@onenightcarnival/dsh-s3	S3-compatible object storage browser: MinIO / OSS / COS / R2, s3_* tools	Sidebar "S3"
@onenightcarnival/dsh-otel	OpenTelemetry GenAI export to Langfuse and other OTLP backends	Settings → Observability
@onenightcarnival/dsh-bridge-browser	Browser bridge: browser_* tools driving the user's tabs through the Chrome / Firefox extension	Settings → General → Browser bridge address
@onenightcarnival/dsh-subscriptions	Codex, ChatGPT and Google Antigravity models, Codex search and image tools	Sidebar "AI subscriptions"
@onenightcarnival/dsh-config-center	MCP and skill management, dedicated uv / Python environment, common settings of built-in plugins	Sidebar → MCP / Skills; Settings → Environment dependencies / Plugins → Common settings
@onenightcarnival/dsh-memory	Layered career records, episodes, human corrections, version history and memory_* tools	Sidebar "Memory"
@onenightcarnival/dsh-toolkit	Integrated package with all seven plugins	Each module's entry point
dsh-browser-extension	Chrome / Firefox MV3 extension paired with the bridge	Browser side panel

Runtime compatibility

Toolkit version	dsh runtime
0.7.x	0.2.0-rc.2 (workspace pin)
0.6.x	0.1.7-rc.2
0.5.x	0.1.5-rc.2

Plugins and hosts use the same runtime line. A mismatch causes typert validation failures and prevents UI loading.

Installation

Every release carries:

File	Purpose
onenightcarnival-dsh-toolkit-<version>.tgz	All seven plugins in one install
onenightcarnival-dsh-rdb-<version>.tgz and the other six	One plugin on its own
dsh-browser-extension-chrome-<version>.zip	Chrome extension, loaded unpacked
SHA256SUMS.txt	Checksums

Installation modes: the integrated toolkit or standalone plugins. The two modes are mutually exclusive.

Desktop app: Plugins → Config center… → Plugins → Install from .tgz, pick the file, restart when prompted.

dsh CLI:

dsh plugin --profile web add file:./onenightcarnival-dsh-toolkit-<version>.tgz
dsh web

Chrome extension: extract to a permanent directory → chrome://extensions → Developer mode → Load unpacked. Local Chrome connections discover the bridge automatically and require no token entry. Firefox requires a source build and token configuration; see browser control.

Module configuration

Module keys, defaults and override examples: integrated package configuration.

Migrating from the standalone packages

Packages use the @onenightcarnival/ scope from 0.5.0. Migration order: remove the old dsh-rdb, dsh-s3 and dsh-otel packages → install their replacements. Connections, credentials and settings remain under ~/.dsh.

Layout

Path	Responsibility
packages/{rdb,s3,otel,browser-bridge,subscriptions,config-center,memory}	Seven standalone plugins
packages/toolkit	Module configuration, host and UI mounting, typert registration
extensions/dsh-browser	Chrome / Firefox MV3 extension
benchmark	Playwright comparison benchmark
docs/browser.md	Browser installation, capabilities, troubleshooting and security boundaries
scripts/build-plugin.mjs	Shared esbuild configuration for host and client bundles
scripts/version.mjs	Package, extension manifest and OTel version synchronization
scripts/package.mjs	Release artifacts and checksums
scripts/check-runtime.mjs	Runtime version validation
scripts/smoke-runtime.mjs	Real host validation in an isolated data directory

Development

Node.js ^22.19 || >=24, pnpm 11. Every command runs at the repository root.

pnpm install
pnpm run build        # all packages, in dependency order
pnpm run typecheck
pnpm run test
pnpm run package      # dist/: eight tarballs, the extension zip, SHA256SUMS.txt

pnpm --filter @onenightcarnival/dsh-rdb run build      # one package
pnpm --filter dsh-browser-extension run build:firefox

Build contract

Item	Contract
Host dependencies	dsh provides @deepseek-ai/*; package build configurations select other dependencies for inlining
Subscription authentication	@cortexkit/antigravity-auth-core is a runtime dependency of subscriptions and toolkit
Integrated package	Bundles the seven packages' sources directly; typechecking covers the same sources
Runtime versions	Pinned through pnpm-workspace.yaml overrides

Installation validation

1. Set DSH_HOME to a temporary directory and run dsh plugin --profile web add file:<tgz>.
2. Start dsh web --no-open --port 0 and exchange the ready log's token URL for a cookie. Each token permits one exchange.
3. Use the cookie to check /api/dsh-toolkit/modules, /api/dsh-rdb/profiles, /api/dsh-s3/profiles, /api/dsh-config-center/mcp and /ext/bridge-config.

Same-version file: packages install from the pnpm store cache; repeat validation requires plugin remove before reinstallation.

Release

The release version comes from the v<version> tag:

git tag v<version>
git push origin v<version>

Stage	Result
Install	Dependencies installed from the lockfile
Version synchronization	scripts/version.mjs set writes the tag version into packages, extension manifests and OTel PLUGIN_VERSION
Validation and build	Typecheck → build → test → package
Release	All files in dist/ attached to the matching GitHub Release

Workflow: release.yml. Artifact versions follow the tag; pnpm version:set <version> synchronizes repository versions. Tags with prerelease suffixes create prereleases; browser manifests retain only the numeric version.
