Moving the agent plane behind per-session presets took five rows with it that the host still owns, and the Web surface stopped booting: `host-apiproxy` injects `subagents`, so with the registry disabled here the entry never activated and `dsh web` died at plugin-tree load. The criterion is injection, not subject matter. A host row that injects a service resolves it before any session exists, so there is no agent to key by: `bash-env` (which `apps/cli/src/web.ts` injects to publish `DSH_WEB_URL`), the `subagents` registry and its spawn/fork backends (a process singleton whose cross-session queries the api-proxy serves, and whose provider names are globally unique), and `tool-subagent-report` (a continuable setup on that singleton, registered once per live session by a list that is not scope-aware) all stay host-plane. What a preset chooses is which delegation TOOLS it sees. The browser lane needs the second half: skill roots now resolve inside a preset, a subtree the lane's include patches cannot reach, so the row's documented environment fallback is pinned for the whole scaffold lifetime — presets mount when a session is created, not at boot. Without it a developer's real ~/.dsh/skills enters replay requests and goldens while CI sees none.

The dsh command is the product launcher for profiles: ordered stacks of plugin-bundle patch layers under the user's own overrides. 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 headless "task" |
Run one fresh persisted session, print the final answer, and exit. |
dsh web |
Alias of --profile web with the Web flag family (--host, --port, --dev, ...). |
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 and headless profiles auto-initialize on first use from shipped templates; any other profile must be created through dsh plugin.
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 a cordis.patch.yml (the user's own patch layer, hot-reloaded on long-lived surfaces). The tree composes over an empty root: each bundle's patch in dsh.profile.bundles order, then the profile's cordis.patch.yml, then the home-level $DSH_HOME/cordis.patch.yml, then --patch overlays, then flag patches. 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), 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 the source launcher.
Development
Production runs require built package and frontend artifacts. From a checkout, pnpm run dsh runs the TypeScript entry and forwards arguments; the source-launcher reference describes the PATH symlink and module-resolution contract.
