javis-os: Skill for Claude Code

.claude/skills/query-wiki/SKILL.md

Query Wiki is a skill for Claude Code from blogminhquy/javis-os. It costs 33 tokens per session (431 once invoked), scanned A, original, MIT.

A workflow for finding and using knowledge stored in a personal wiki or “second brain,” a collection of saved notes and sources. It combines information, compares ideas, forms hypotheses, and includes citations.

In plain words
What is it for?
Use it to summarize a topic, compare frameworks, list relevant notes, build a visual explanation, translate material, or record reusable findings and unanswered questions.
Why use it?
It helps answer questions from existing notes without guessing or losing track of where specific claims came from. It also identifies gaps when the stored material does not cover the question.

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

Query Wiki 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 11d 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.

What it actually says

QUERY - trả lời từ wiki (có citation, compounding)

Khi nào dùng

Kích hoạt khi người dùng hỏi/khai thác tri thức trong Second Brain, vd "tổng hợp các framework về X", "so sánh A vs B vs C", "wiki có gì về Y".

Năm kiểu khai thác: tổng hợp, so sánh, giả thuyết, liệt kê, trực quan hoá. Luôn trả lời có trích dẫn và lưu lại kết quả giá trị.

  1. Đọc wiki/index.md TRƯỚC để biết có trang nào.
  2. Đọc các trang wiki liên quan (theo nhóm/tên); đọc trang được [[link]] tới nếu cần đủ context.
  3. Thiếu -> đọc sources/ tương ứng. Vẫn thiếu -> append 1 dòng vào wiki/_open-questions.md.
  4. Trả lời có [[citation]] cho mọi khẳng định cụ thể. Nói rõ chỗ nào wiki chưa cover thay vì bịa.
  5. Nếu câu trả lời có GIÁ TRỊ TÁI DÙNG (so sánh, phân tích, mapping mới) -> đề xuất lưu thành 1 trang wiki mới (compounding: khám phá cũng tích luỹ vào bộ não, không tan vào lịch sử chat).

7 dạng câu hỏi chất lượng cao: Tổng hợp (bảng so sánh) · So sánh 3+ (ma trận) · Giả thuyết (phân tích ảnh hưởng) · Gán nhãn/liệt kê · Trực quan hoá (canvas/sơ đồ) · Dịch/chuyển ngữ · Tự kiểm gap (append open-questions).

Changes

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.
