Tianyi Cui 0d6bfd8856 refactor(process): split the process manager out of the bash executor
New process/ capability family: @deepseek-ai/dsh-process owns ctx.processes —
abstract ProcessManager.spawn(spec) over a fully-explicit ProcessSpawnSpec —
plus the shared DSH_* managed-environment and CollectedOutput vocabulary;
@deepseek-ai/dsh-process-local carries the former bash-local run.ts plumbing
(detached groups, tail-keep spill-backed output, credential scrub, kill
escalation, kill-and-join disposal) with no config of its own.

dsh-bash-local becomes a consumer: it keeps command defaulting, the fused
deadline timedOut/aborted classification, the model-friendly terminal env
(now merged through the ordinary env channel), and the [stderr]-marked
background read merge, and spawns through ctx.processes. Background-process
lifetime moves to the manager, so an executor reload no longer kills live
background work; a background spawn failure is injected once into the read
path instead of being buffered as fake stderr. dsh-bash re-exports the moved
vocabulary so bash consumers keep one import root; dsh-bash-sandbox only
redeclares the inherited inject.

Every composition loading a bash executor now loads dsh-process-local (CLI,
examples, python bundled runtime, create-sdk bash feature, inline test
configs).

@deepseek-ai/dsh

The dsh command-line entry follows the apps/ assembly tier: apps/* are product assemblies over packages/* libraries. Plain dsh boots the interactive TUI coding agent, dsh -p "task" runs one headless turn, and dsh web serves the browser UI.

Argv is parsed once through a Commander adapter (src/args.ts): one program whose default (no subcommand) is the TUI/headless surface (--config, -p/--prompt, --resume) and whose web subcommand is the browser UI. src/bin.ts switches on the resolved mode and dynamic-imports only that mode's module. dsh --help lists every mode and dsh web --help renders the web usage, dsh --version prints this app's version, and an unknown option or a mistyped --resume fails loud (stderr, exit 1) instead of misrouting. dsh web's --host/--port are unvalidated pass-through overrides: the dsh-host-webserver schema is the single source of both the default (the shipped cordis.yml value when a flag is absent) and validity, and rejects a bad value at boot.

The TUI surface:

  • boots the shipped default config (examples/tui-agent/cordis.yml), or the tree named by --config <path> (the demo/test escape for booting an alternate example tree), through dsh-app-boot;
  • resumes a persisted session with dsh --resume <session-id> and, when the Node host exposes process.execve, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalized dsh --resume <id>; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context under RESUME_SESSION_ID_KEY (no environment variable), which the shipped config reads through !!js, and a missing or unreadable id fails loud instead of creating a fresh session;
  • treats the invoking directory as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
  • tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential cordis toolset can read and modify it;
  • applies the personal overlay from ~/.dsh (see app-boot's Personal config): .env fills environment gaps (ambient > project .env > personal .env), config.yaml patches the booted tree.

The Web and headless surfaces boot one shared composition (cordis.yml): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless --workspace-root <path> overrides it, load applicable AGENTS.md/CLAUDE.md instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel dsh -p runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (pnpm run build && pnpm run build:web).

Install (developer machine)

Symlink the source-running launcher onto your PATH; it resolves the checkout through its own real path, so code changes apply on the next launch with no build step:

ln -sf "$(pwd)/bin/dsh" ~/.local/bin/dsh

pnpm run dsh runs the same entry from the repo root and forwards arguments directly, for example pnpm run dsh -p "task". The built form (lib/bin.js, via pnpm run build) boots the same config under plain Node.
