## What it does

DeepSpace is one package for real-time collaborative apps on Cloudflare Workers. It covers auth, RBAC, synchronized records, messaging, integrations, payments and deploys to `<name>.app.space`. The skill sets the working order: how to start, how to operate, how to consult the docs.

The docs at docs.deep.space are treated as the authority. The skill tells you to fetch the `llms.txt` index first, pull one or two pages as Markdown, and grep `llms-full.txt` when you need to prove a topic exists at all. For exact type signatures, read the installed package: `ls node_modules/deepspace/dist/*.d.ts`.

App commands need auth first: `npx deepspace auth whoami --json`, and `npx deepspace auth login` when signed out. Login opens browser OAuth and polls for up to ten minutes, so a container or CI shell has no browser — there you use the env credentials named by `auth login --help`. Scaffolding needs npm 11.6+: npm 10's peer resolver can crash on the template's Vitest dependency even on a supported Node version. Check `node --version` and `npm --version` before you start.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add deepdotspace/deepspace-skill --skill deepspace -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add deepdotspace/deepspace-skill --skill deepspace -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add deepdotspace/deepspace-skill --skill deepspace -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install deepdotspace/deepspace-skill deepspace
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add deepdotspace/deepspace-skill --skill deepspace -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/deepdotspace/deepspace-skill --path skills/deepspace
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add deepdotspace/deepspace-skill --skill deepspace -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/deepdotspace/deepspace-skill/tree/HEAD/skills/deepspace/SKILL.md

## When to use it
- scaffold a real-time app on Cloudflare Workers
- add record sync and presence to an existing project
- wire up RBAC and payments through the DeepSpace SDK
- deploy an app to app.space
- create or migrate docs with documentation.json

## Example prompts
- scaffold a new DeepSpace app and start the dev server
- add synchronized records and presence to this project
- list the available integrations with npx deepspace integrations list

# DeepSpace

DeepSpace is one package for real-time collaborative apps on Cloudflare
Workers. It provides auth, RBAC, synchronized records, messaging, integrations,
payments, and deploys to `<name>.app.space`.

This skill is the bootstrap: how to start, how to operate, and how to consult
the documentation. The documentation at <https://docs.deep.space> is the
authority for everything else — it is written to be opinionated, so when it
recommends an approach, take that as the default rather than one option among
many.

## One source authority

Every app has exactly one Git authority — DeepSpace source (packaged,
commit-first) or GitHub source (manual; deploys ship the local working tree,
dirty bytes included). A new app starts unclaimed, then its first
source-producing action latches one authority **once, permanently**: a deploy
from a checkout with a selected GitHub remote claims that repository, while
the first `deepspace push` or a deploy without a GitHub remote claims
DeepSpace. There is no manual declaration or later transfer. Never run
`deepspace push` before the first GitHub deploy unless the user has chosen
DeepSpace source; after a GitHub claim, all DeepSpace source verbs refuse with
`source_managed_by_github`. `deepspace app source` is read-only (the old
setter refuses `source_inferred`). Never maintain two sources of truth, and
read the source-control and workspaces docs before any source, push, pull, or
clone operation — the docs, not this skill, state what each verb does under
each authority.

## Sharing and handing over an app

Collaborators and ownership transfer (`deepspace app collaborators …`,
`deepspace app transfer …`) change who can deploy, read secrets, and own the
app. Read the app-identity guide before either — it states exactly what each
grant confers and what a transfer takes away — and treat both as decisions to
surface to the user, not steps to run in passing.

## How to read the documentation

Consult the docs BEFORE building in an area, not after something breaks. The
reading procedure:

1. **Fetch the index once per task area:** <https://docs.deep.space/llms.txt>
```
