Drop the bare `dsh <config>` positional in favor of a `--config <path>` flag. Without a root positional, `web` can be a real Commander subcommand in one program instead of the reserved-first-token dispatch to a second parser, so `dsh --help` lists every mode natively (no hand-pasted command text) and the second parser + reserved-token machinery are gone. Grammar: dsh TUI (shipped tree + ~/.dsh overlay) dsh --config <path> TUI, alternate tree (demos/tests only) dsh --resume <id> TUI, resume a session dsh -p "task" headless one-shot dsh web [--host --port --dev] `dsh` is the product front door with no positional; `--config` exists only so demo:cordis, demo:code-mode, and the keyless PTY smokes can point the shipped bin at an example tree. Those three sites and the /resume re-exec argv move to `--config <path>`. The `-p` + `--config`/`--resume` mode-mixing guard and the cordis.yml-owns-host/port-default fix are preserved. Agent Note + Chinese pair, README, tui.ts docs updated. All 13 PTY smokes (including code-mode via --config and the exec-replace resume handoff) green.

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 an invalid --host/--port/--resume value fails loud (stderr, exit 1) instead of misrouting.
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.
