Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00075 | $0.03809 |
| Opus 5 | $0.00037 | $0.01904 |
| Sonnet 5 | $0.00015 | $0.00762 |
| Haiku 4.5 | $0.00007 | $0.00381 |
Grade A, and why
vbs-scan-security 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 5d ago.
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 — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vbsec — Security Scanner cho Vibe Coders (Antigravity variant)
Quét lỗ hổng bảo mật cho code do AI sinh ra (vibe code). Bộ skill này check 21 lỗi bảo mật phổ biến nhất của vibe code, kế thừa kiến trúc SMALL/LARGE mode, tổng quát hóa cross-language + chuyên sâu cho Go/PHP/Python/TypeScript/.NET.
Public repo: https://github.com/tanviet12/vbsec License: MIT Platform: Google Antigravity. Phiên bản Claude Code spawn parallel sub-agents; phiên bản này dùng sequential chunking để giữ portability — chậm hơn ~3× nhưng output identical.
Invocation
Trong Antigravity Agent Manager chat box:
- Auto-trigger: nói tự nhiên — "scan security cho repo này", "kiểm tra bảo mật", "audit security". Antigravity tự match description và load skill.
- Explicit slash command: nếu workspace có file
.agent/workflows/vbs-scan-security.md(xem README để biết cách tạo), gõ/vbs-scan-securityđể invoke.
| Argument | Scope | Mô tả |
|---|---|---|
| (không args) | Toàn repo | Mặc định — quét toàn bộ repo |
all |
Toàn repo | Alias explicit |
uncommitted / diff |
Uncommitted changes | Staged + unstaged |
staged |
Staged files only | Pre-commit scan |
commit within Xdays |
Recent commits | Quét commit X ngày gần đây |
commit id <sha> |
Specific commit | Quét 1 commit |
pr id <number> |
Pull request | Quét PR diff (cần gh CLI) |
Lựa chọn ngôn ngữ output: lang=vi / --vi (mặc định) hoặc lang=en / --en.
Ví dụ:
scan security uncommitted lang=en
/vbs-scan-security pr id 42
audit security commit within 7days
CRITICAL: Cách dùng skill này (cho LLM agent)
Các pattern bash/grep trong rule files là VÍ DỤ minh họa, KHÔNG phải lệnh chạy literal.
Nguyên tắc
- Lý luận, không pattern-match thuần — Hiểu intent bảo mật đằng sau mỗi check, không chỉ tìm chuỗi
- Dùng tool phù hợp — Antigravity built-in file/grep tools (read, grep, bash/shell), không gọi grep/find shell thô khi tool native có sẵn
- Đọc context đầy đủ — Khi gặp pattern, đọc hàm xung quanh để hiểu đây có thực sự là lỗ hổng không
- Phân loại trust level — Một query có format chuỗi chỉ nguy hiểm nếu data ghép vào là L1 (untrusted)
What ships with it

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.
- 5d ago First seen · 337 lines · 75 tokens per session scan A e0c9cba9a96b
vbs-scan-security is a skill published in the GitHub repository tanviet12/vbsec (265 stars, last pushed 3mo ago), licensed MIT. It adds 75 tokens to every session and 3,809 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
