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.

Security

Grade A, and why

dym-arex-skill-cai-thu-vien-skill scanned grade A with 0 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: dym-arex-skill-cai-thu-vien-skill — Cài & bảo trì thư viện AREX-Skill

Vì sao dùng: disco cài xong vẫn chưa có kiến thức vận hành nào. Bước này mới nạp 1.000 repo skill + router vào agent dir. Sinh ra cái gì: ~/.disco/agent/skills/repositories/{repo-skills,repo-skills-router}/, kèm bản ghi commit nguồn để về sau đối chiếu drift.


1. Cài

disco repo-skills install

Lệnh này clone shallow (--depth 1 --filter=blob:none) repo chính thức, chỉ copy phần runtime collection, rồi ghi lại commit nguồn. Git phải có sẵn trên máy.

Output mẫu (in ra bởi printInstallResult):

Installed repository skills from commit <sha>.
Official skills: <n>
Local skills preserved: <n>
Total repo skills: <n>
Routed repositories: 1000
Area-family assignments: 2209
Router taxonomy: 20 areas, 178 families
Router: enabled
Start a new Researcher session to load the updated repository skill index.

Chạy lại khi đã cài rồi thì nó không cài lại, chỉ in: Repository skills are already managed. Run 'disco repo-skills update' to check for updates.

2. Soi trạng thái — và đây là lệnh dùng làm cổng CI

disco repo-skills status

status hoàn toàn local: kiểm digest của skill được quản lý, sự hiện diện của router, độ phủ routing. Nó không gọi GitHub. In:

Installed: yes
Managed by DisCo: yes
Source: <repo url>
Commit: <sha> (<12 ký tự đầu>)
Official skills / Local skills / Total repo skills
Routed repositories / Area-family assignments / Router taxonomy
Files: <n>
Router: enabled | disabled | not installed
Drift: none          ← hoặc "Drift/issues:" kèm danh sách

Exit code (kiểm bằng mã, không phải bằng README):

Tình huống Exit
Sạch, không drift 0
Có bất kỳ mục nào trong status.issues (drift / thiếu router / hỏng) 1
Sai cú pháp lệnh (--force cho status, subcommand lạ, router foo) 2

Cụ thể: repo-skills.ts set process.exitCode = 1 khi status.issues.length > 0; mọi lỗi parse ném RepoSkillsLibraryError(..., 2). Đừng viết script kiểu || true — 1 và 2 mang nghĩa khác nhau.

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.
