The adapter no longer validates --host/--port or declares the allowed set: LOOPBACK_HOST/ALL_INTERFACES_HOST leave args.ts. --host/--port are now unvalidated pass-through overrides — the adapter only Number-coerces the port string (the dsh-host-webserver schema wants a number). That schema (host a 127.0.0.1/0.0.0.0 literal union, port a natural <= 65535) is the single source of both the default (the shipped cordis.yml webserver row) and validity; AppCLIEntry patches an explicit flag into that row, so a bad host/port fails loud at the schema on boot (verified: `dsh web --host 9.9.9.9` and `--port abc` both exit 1 with the schema's ValidationError). web.ts keeps two display-only literals (the printed loopback URL, the all-interfaces LAN-detection check), commented as mirrors of the schema, not a source of truth. Agent Note + Chinese pair and README updated; the args spec drops the host/port exit-code cases (now the schema's job, covered by the web smoke on boot).
@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), throughdsh-app-boot; - resumes a persisted session with
dsh --resume <session-id>and, when the Node host exposesprocess.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 normalizeddsh --resume <id>; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context underRESUME_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
cordistoolset can read and modify it; - applies the personal overlay from
~/.dsh(see app-boot's Personal config):.envfills environment gaps (ambient > project.env> personal.env),config.yamlpatches the booted tree.
The Web surface treats its invoking directory as the default project, loads applicable AGENTS.md/CLAUDE.md instructions into each agent-loop request prefix with a 65,536-byte render budget, and opts into first-message model titles. The headless surface retains deterministic fallback titles without making the auxiliary title-model request.
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.
