@deepseek-ai/dsh

The dsh command-line entry, following the apps/ assembly tier proposed by the dsh web PR (#443): apps/* are product assemblies over packages/* libraries. This branch ships one surface — plain dsh [config.yml] boots the interactive TUI coding agent — and reserves the web and -p/--prompt subcommands for that PR so the dispatch merges as a union.

The TUI surface:

• boots the shipped default config (examples/tui-agent/cordis.yml) or an explicit config argument, through dsh-app-boot;
• resumes a persisted session with dsh --resume <session-id> — the form the TUI prints on exit and lists under /resume; the flag sets RESUME_SESSION_ID before boot so the shipped config rehydrates that session, and a missing or unreadable id fails loud and exits nonzero;
• 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.

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 demo:tui runs the same entry from the repo root. The built form (lib/bin.js, via pnpm run build) needs node --expose-internals for the shipped config's HMR entry, exactly like the demo bins.
