What is dym-arex-skill-cai-dat-disco?

An installation guide for the disco command-line tool, which the AREX-Skill system uses to install and run its skill libraries and creator tools. It covers required Node.js and Git versions, setup files, and supported installation methods.

Use it to install disco on macOS, Linux, WSL, Git Bash, or Windows PowerShell and prepare a model provider for the tool.

It removes the need to work out the required runtime, configuration, and installation steps yourself. Without disco, the described AREX-Skill libraries and tools cannot be used.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.01436
Opus 5.5	$0.00023	$0.00574
Sonnet 5.5	$0.00011	$0.00287
Haiku 4.5	$0.00006	$0.00144

Security

Grade C, and why

dym-arex-skill-cai-dat-disco scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`engines.node` trong `cli/package.json` là `">=22.19.0"`. Node 22.17.x **không đạt** — bản cài qua npm sẽ cảnh báo/chặn engine, còn bản cài qua installer curl thì tự chuẩn bị runtime Node riêng ở mức user.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: dym-arex-skill-cai-dat-disco — Cài `disco` CLI

Vì sao dùng: Không có disco thì không dùng được gì trong AREX-Skill — cả thư viện 1.000 repo skill lẫn 15 meta skill Creator đều chạy qua CLI này. Sinh ra cái gì: Một lệnh disco global, thư mục cấu hình ~/.disco/agent/, và ít nhất một provider model đã cấu hình.

0. Điều kiện tiên quyết (kiểm trước, đừng đoán)

node --version    # PHẢI >= 22.19.0
git --version     # cần cho `disco repo-skills install` (nó clone shallow)

engines.node trong cli/package.json là ">=22.19.0". Node 22.17.x không đạt — bản cài qua npm sẽ cảnh báo/chặn engine, còn bản cài qua installer curl thì tự chuẩn bị runtime Node riêng ở mức user.

1. Cách khuyến nghị — managed installer (macOS / Linux / WSL / Git Bash)

curl -fsSL https://github.com/VectorSpaceLab/AREX-Skill/releases/latest/download/install-disco.sh | sh

Windows PowerShell:

powershell -NoProfile -ExecutionPolicy Bypass -Command "& { irm https://github.com/VectorSpaceLab/AREX-Skill/releases/latest/download/install-disco.ps1 | iex }"

Installer đặt state release dưới ~/.disco/agent/install/, không đè lệnh disco lạ đã có, không xoá settings/credentials/sessions/skills của bạn. Nếu nó bảo refresh PATH thì mở shell mới.

Kiểm chứng:

disco --version     # in số version rồi thoát 0
disco --help        # in bảng Commands/Options/Examples

Gỡ riêng phần installer quản lý:

~/.disco/agent/install/install-disco.sh --uninstall

2. Cách thay thế — package manager

npm  install -g --ignore-scripts @arex-skill/disco
pnpm add     -g --ignore-scripts @arex-skill/disco
bun  add     -g --ignore-scripts @arex-skill/disco

Cập nhật / gỡ đúng bằng manager đã cài:

npm update -g @arex-skill/disco   ;  npm uninstall -g @arex-skill/disco
pnpm update -g @arex-skill/disco  ;  pnpm remove -g @arex-skill/disco
bun update -g @arex-skill/disco   ;  bun uninstall -g @arex-skill/disco

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
