## What it does

Univer CLI is a terminal tool for authoring `.univer` files. A single file can hold several Units — Sheet, Doc, Slide, Base, Board — each addressed by `unitId`. The skill loads the right instructions for the task at hand so commands and Facade APIs match the CLI version you have installed.

Runtime skills ship with the CLI: `core` covers the shared model and workflow, then one skill per Unit type, plus `embed` for nesting one Unit inside another and `cross-unit-formula` for formulas that read a neighbouring Unit. Edits land in an isolated worktree rather than the reviewed `trunk`, so nothing reaches the file until you merge. A command returning success is not proof the model is correct, so the skill asks you to read the target back and check rendered output when appearance matters.

You need the CLI itself first: `npm install -g univer-cli`, then `univer doctor` to check the runtime. If `doctor` reports a blocking runtime failure, the skill says to stop and report the diagnostic instead of reaching for other tools. Editing `.univer` storage directly, or swapping in an unrelated file writer, is off the table.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dream-num/skills --skill univer-cli -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/univer-cli/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/univer-cli/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dream-num/skills --skill univer-cli -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/univer-cli/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dream-num/skills --skill univer-cli -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/univer-cli/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dream-num/skills univer-cli
```

2. **Manually: put the files in place**
- File: `.github/skills/univer-cli/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dream-num/skills --skill univer-cli -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dream-num/skills --path skills/univer-cli
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/univer-cli/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dream-num/skills --skill univer-cli -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- build a spreadsheet with formulas and charts inside a `.univer` file
- nest one Unit inside another Unit
- read a Sheet range from a cell in a different Unit
- confirm the stored model matches what you asked for
- export slides or a document to another format

## Example prompts
- Load the univer-cli skill and list the Units inside `report.univer`
- Create a new Sheet with a sales table in a worktree and verify it with a readback
- Take a screenshot of a slide page in `deck.univer` so I can see how it renders

# Univer CLI

Terminal-native authoring and inspection for multi-Unit `.univer` files. The CLI provides isolated
worktrees, version-matched Facade guidance, model readback, and browser review.

Install:

```bash
npm install -g univer-cli
univer doctor
```

## Keep the CLI current

Use these commands to compare the installed CLI with the latest public release:

```bash
univer --version
npm view univer-cli@latest version --registry=https://registry.npmjs.org/
```

When a newer version is available, complete the current Univer task before updating:

```bash
univer update
univer doctor --json
univer skills get core
```

If `univer update` reports that the shared daemon must stop, rerun it with `--force` after confirming
that stopping the daemon is safe. Reload core and the target Unit Skill after every update.

## Start here

This file is the discovery entry, not the operational guide. Before using Univer commands for a
task, load the complete core Skill from the installed CLI:

```bash
univer skills get core          # shared model, workflow, evidence, and handoff
univer skills get core --full   # include direct references and templates
```

Runtime Skills ship with the CLI so their commands and Facade APIs match the installed version.

## Core Model

- A `.univer` path is the authoritative multi-Unit target. Always address the file explicitly.
- A Unit is a top-level Sheet, Doc, Slide, Base, or Board identified by `unitId`; sheet names, pages,
  tables, ranges, shapes, and records live inside that Unit.
- `trunk` is the reviewed main line. A worktree is an isolated scope for agent changes; there is no
  implicit current worktree.
- Command success is not correctness evidence. Read back the target model, verify task-specific
  assertions, and inspect rendered output when appearance matters.

Use public CLI and Facade surfaces. The worktree commit path is the durable write boundary, and
merge remains an explicit review decision.

## Unit Skills

After core, load the Skill matching the target top-level Unit before authoring:

```bash
univer skills get sheet
univer skills get doc
univer skills get slide
univer skills get base
univer skills get board
```

Use `univer skills list` to discover the installed set. Each Unit Skill owns its creation recipe,
Facade entrypoints, readback guidance, and visual verification requirements.
