npm: codsh-cli · command: codsh

/ship takes one sentence to verified code. A terminal coding agent on the DeepSeek Harness.

Install

npm install -g @deepseek-ai/dsh codsh-cli   # already have dsh? npm i -g codsh-cli
codsh

Zero-dependency launcher. codsh is dsh --profile code. Key: DEEPSEEK_API_KEY.

codsh --resume <id> · codsh --continue · codsh -p "task" · codsh --version · codsh update

A session says so when a newer codsh is published. codsh update moves the pair from the shell, /update does it from inside a session, and either way the next boot registers the matching runtime. CODSH_UPDATE_CHECK=off silences the automatic check; asking still asks.

Or skip the launcher:

dsh plugin --profile code add codsh-bundle
dsh --profile code

/ship

/ship <one-sentence idea> — grill, two approvals, then autonomous:

1. Grill — design-tree interview; facts are inspected, each round asks the open frontier with a recommended answer.
2. Spec — synthesized automatically (to-spec). You confirm. Each criterion names its proving command.
3. Tickets — tracer-bullet slices, written automatically. You approve. Baseline runs before any code.
4. Landing — TDD at the spec's seams; each green ticket is a commit.
5. Done — every criterion re-run and reported.

Bare /ship resumes an unfinished spec.

/ship let long diffs open in a pager instead of scrolling past

The surface

The site shows each one as a real capture. In brief:

Reading a long session

• A submitted prompt takes the viewport top and its reply fills the space beneath it. Read back into history and the way home is the same frame: the wheel and PgDn land on it again.
• Whatever you are reading, the prompt that asked for it pins itself at the top; the next prompt pushes it away.
• A one-column timeline on the right marks the turn you are in — ticks and arrows click-jump, hover previews the real prompt lines. Shift+←/→ does it from the keyboard, and /jump is a searchable, reversible preview.
• Long blocks fold: click one, Ctrl+O all, and what you opened by hand stays open across later turns.
• /view 1 opens an answer full screen, /view 1:1 its first code block; Esc restores the conversation exactly. /copy addresses the same targets — raw Markdown, or fence-free code.
• /diff reads uncommitted changes in the same reader rather than scrolling them past, and a diff card too long for its own body opens there on click. Piped, it stays lines.

Working

• Alternate screen; the box never leaves the bottom; quitting gives your shell back untouched.
• Todos stay in the chrome (Ctrl+T / /todos). Markdown, thinking, and tool cards stream in. Drag to copy.
• Ctrl+V pastes images (native vision; DeepSeek text models borrow Vision Exp automatically; other text routes keep the file + optional sidecar fallback).
• / commands, $ skills, ! shell, @ files — the menu sits above the box. ⇧Tab is plan mode.
• Approvals, /model, and /resume are arrow-key widgets; /clear, Esc Esc, /init, and /update round it out. !cmd prints in-session and the agent sees it.

Off a TTY it becomes a line reader: no widgets, no drawing.

Development

pnpm install
pnpm run dev                 # build → .dev-home → boot
MOCK=markdown pnpm run dev   # keyless, against the e2e mock
pnpm test
pnpm run test:e2e            # pack, install, drive the real binary
CAPTURE_SCREENS=1 pnpm run site:screens   # re-shoot the site's terminals

pnpm run sync:dsh tracks published @deepseek-ai/dsh-* releases. This repo never forks the harness.
