The package exported six functions, four of them shaped by one SDK's transport each: a dispatcher factory, a `node:http` agent factory, a proxy-URL lookup, and a policy accessor. Review asked whether the call sites could converge instead of the package growing an export per SDK. They could, and each removal took a whole shape with it: - The OTLP exporter moves to the SDK's `fetch` delegate, retiring `createNodeHttpAgent`. Its Node-version floor goes too: `proxyEnv` on an `http.Agent` needs 22.21 or 24.5, inside the engines range, so telemetry was direct on 22.19, 22.20, and 24.0-24.4. The cost is `compression`, a Node-transport option; the plugin now refuses it, `keepAlive`, and `httpAgentOptions` at load instead of ignoring them. - `web-fetch-http` builds its own address-pinning agent under an annotated `proxy-exempt:` exemption, retiring `createDispatcher`. Pinning is per-request state a process-wide dispatcher cannot hold. - E2B reads `route.proxy`, retiring `proxyUrlFor`. What remains is `installProxyFromEnvironment`, `proxyRouteFor`, `proxyEnvironmentForChild`, and `clearedProxyEnv` — one per way a caller can need the policy. Installation absorbs resolution and diagnostic reporting, which no caller needed apart. `proxyRouteFor` also closes a defect the old accessor made expressible: `web-fetch-http` read the policy to decide whether to pin, then read it again to build a transport, so an unmount between the two returned a direct, unpinned agent for a URL the first read had cleared as proxied. A route carries the answer and the transport that answer assumed. Every egress spec now installs through `installProxyFromEnvironment`, so no test asserts a policy object a real launch could not produce.

The dsh command is the sole supported Node application launcher: profiles are ordered stacks of plugin-bundle patch layers under the user's own overrides. SDK and ACP are profiles, not separate public bins. The Python runtime wheel packages this same command; the SDK defaults to sdk, and the minimal example selects sdk-minimal. src/args.ts owns the command grammar, and src/bin.ts loads only the selected runner. Invalid commands, options from another mode, configuration errors, and boot failures exit nonzero.
Entry modes
| Command | Purpose |
|---|---|
dsh --profile <name> |
Boot the named profile under $DSH_HOME/profiles/<name>. |
dsh --profile acp |
Serve automation clients over ACP stdio until disconnect. |
dsh --profile headless "job" |
Run one fresh persisted session, print the final answer, and exit. |
dsh --profile sdk |
Serve SDK clients over JSON-RPC stdio until shutdown or disconnect. |
dsh --profile sdk-minimal |
Serve SDK clients with the standalone minimal agent tree. |
dsh web |
Alias of --profile web. |
dsh plugin --profile <name> <pnpm args> |
Manage a profile's plugins by forwarding to pnpm in the profile directory. |
The invoking directory is the default workspace root. The web, headless, sdk, sdk-minimal, and acp profiles auto-initialize on first use from shipped templates; any other profile must be created through dsh plugin.
App arguments
The launcher parses only its own flags and hands everything after them to the booted profile, where any injected app plugin may parse the shared immutable snapshot (dsh-cmdline). The first token the launcher does not recognize starts the app's arguments:
dsh --profile web --port 8080 # --port belongs to the web app
dsh --profile tui --resume <id> # example, assuming the tui profile is installed; --resume belongs to the terminal app
dsh --profile headless "run the tests"
dsh --profile web --help # the web app's flags, not the launcher's
dsh --help # the launcher's own help
Profiles
A profile directory holds a package.json (out-of-tree plugin dependencies plus the profile manifest dsh.profile with its ordered bundles list and patchReload lifecycle) and a cordis.patch.yml (the user's own patch layer). patchReload: live watches the profile and home-level patch files; startup applies them once.
The tree composes over an empty root:
- each bundle's patch in
dsh.profile.bundlesorder - then the profile's
cordis.patch.yml, then the home-level$DSH_HOME/cordis.patch.yml - then
--patchoverlays
Bundles named in dsh.profile.bundles resolve from the dsh installation first (@deepseek-ai/dsh-base, @deepseek-ai/dsh-web-app, @deepseek-ai/dsh-headless, @deepseek-ai/dsh-sdk-app, @deepseek-ai/dsh-sdk-minimal, @deepseek-ai/dsh-acp-app), then from the profile's own node_modules, where pnpm installs out-of-tree plugins.
Use --dump-default-config and --dump-config to inspect the composed tree without booting it.
The CLI behavior reference owns exact layer precedence, flags, shutdown behavior, deployment defaults, and source execution.
Optional overlays
config/examples/ ships opt-in overlays for GitHub review webhooks, session-local Schedule, memory MCP servers, and runtime Cordis tools. They are never part of a default profile; the user guides and developer practice guides own setup and safety instructions.
Development
Production runs require built package and frontend artifacts. From the repository root, run pnpm run build separately, then use pnpm dsh <args...> to run the TypeScript entry and forward every argument; the source-execution reference owns the module-resolution contract.
