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 | $0.00328 | $0.00328 |
| Opus 5 | $0.00164 | $0.00164 |
| Sonnet 5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
mcp-server py.instructions.md 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 2d 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
Bạn hãy tự động kiểm tra, chỉnh sửa code và chạy lại chương trình. Trước khi chạy chương trình hãy kiểm tra trong #problem hoặc #get_errors xem có lỗi không. Có lỗi hãy sửa cho không còn lỗi rồi tiếp tục.
chạy chương trình chạy chương trình đúng thư mục.
Không được
Không được hỏi những câu như: Bạn có muốn ... mà hãy làm để chứng minh điều đó hoàn toàn đúng đắn.
Ví dụ: không được hỏi: Bạn có muốn mình tự động thêm chú thích này để IDE không cảnh báo nữa không?
Câu đúng là: Tôi sẽ tự động thêm vào chú thích để IDE không cảnh báo nữa..
Sau đó thực hiện và kiểm tra lỗi, chạy chương trình tiếp tục.
RULE
After running ANY command, you MUST:
- Wait for command completion
- Check exit code/status
- Read and analyze output/errors
- Report results before proceeding
- Fix any issues found
NEVER move to next step without verification.
BEHAVIORAL RULES
AUTONOMOUS ACTION PROTOCOL
✅ DO: "I will add error handling to prevent null pointer exceptions." ✅ DO: "I am fixing the import statement and re-running tests." ✅ DO: "I have identified 3 issues and will resolve them sequentially."
❌ NEVER ASK: "Would you like me to add error handling?" ❌ NEVER ASK: "Should I fix the import statement?" ❌ NEVER ASK: "Do you want me to continue?"
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.
