## What it does

The skill wires an agent into your personal Cubox reading list through the `cubox-cli` tool. It can list cards by keyword, filter them by folder, tag, read status or star, and pull the full article text along with annotations and the AI insight. A separate `card rag` command searches by meaning instead of matching words.

Under the hood it is a set of CLI commands. `folder list` and `tag list` show the structure, `save` adds one link or a batch, `update` moves cards and changes tags, and `tag merge` plus `tag delete` clean up tag sprawl. Most queries return compact JSON; `-o pretty` indents it and `-o text` gives plain output. One catch: `save`, `update` and `auth` print plain text even with `-o json`, so do not treat every successful run as parseable JSON.

You need a token before the first call. The skill forbids pasting it into chat or into command arguments, so have the user run `cubox-cli auth login` in their own terminal or pipe the token through stdin. Saved page content is treated as untrusted: the agent may quote it, but should not act on instructions found inside it. Worth checking that you are comfortable with the write access this grants.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add OLCUBO/cubox-cli --skill cubox -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add OLCUBO/cubox-cli --skill cubox -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install OLCUBO/cubox-cli cubox
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/OLCUBO/cubox-cli --path skills/cubox
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add OLCUBO/cubox-cli --skill cubox -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/OLCUBO/cubox-cli/tree/HEAD/skills/cubox/SKILL.md

## When to use it
- find a saved article by meaning rather than exact wording
- pull the full text of a bookmarked page with its annotations
- save a batch of links into a folder with tags
- merge duplicate tags and delete the ones you no longer use
- list unread cards filtered by folder or tag

## Example prompts
- Search my Cubox for everything I saved about vector databases and show the summaries
- Save this link to the Read Later folder with the tag ai
- Merge the tags ml and machine-learning into one

# cubox-cli

Manage Cubox bookmarks via the `cubox-cli` command-line tool.

## Authentication and Secrets

If any command fails with "API Key does not exist", never ask the user to paste their API token into chat and never construct commands that embed a literal token in argv. Use one of these safe paths:

1. **Interactive login:** ask the user to run `cubox-cli auth login` in their own terminal.
2. **Agent / CI without persistence:** ask the user to set `CUBOX_SERVER` and `CUBOX_TOKEN` in their shell before invoking the CLI.
3. **Non-interactive persisted login:** ask the user to pipe the token via stdin: `printf '%s' "$TOKEN" | cubox-cli auth login --server cubox.pro --token-stdin`.

Forbidden: asking for tokens in chat, suggesting `cubox-cli auth login --token <literal-token>`, committing credentials, or copying tokens into screenshots or shared notes. If a token may have leaked, tell the user to rotate it from the Cubox extensions page.

## Commands

Most query commands and batch mutation commands output compact JSON by default. Add `-o pretty` for indented JSON, `-o text` for human-readable output.

Known success-output exceptions: `save`, `update`, and `auth` subcommands currently print plain text even when `-o json` is selected. Do not assume every successful command stdout is parseable JSON.

### List Folders

```bash
cubox-cli folder list
```

Returns: `[{ "id", "nested_name", "name", "parent_id", "uncategorized" }]`

### List Tags

```bash
cubox-cli tag list
```

Returns: `[{ "id", "nested_name", "name", "parent_id" }]`

### Manage Tags (rename / delete / merge)

These mutate tags directly. They take **tag IDs** (not names) — call `tag list` first if you only have a name.

```bash
# Rename a tag — only the leaf segment changes; nested children stay attached
cubox-cli tag update --id TAG_ID --new-name NEW_NAME

# Batch delete tags — cards keep their other tags; only the tag-card link is removed
cubox-cli tag delete --id TAG_ID[,ID2,...]

# Merge source tags into a target tag — cards are re-tagged onto the target,
# then the source tags are deleted
cubox-cli tag merge --source SRC_ID[,ID2,...] --target TARGET_ID
```
