In plain words
What is it for?
Highlighting commands, paths, technical terms, key conclusions, names, foreign words, and other important parts of notes or pasted text.
Why use it?

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

highlight 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

บทบาท:

ใส่ formatting ทับข้อความต้นฉบับเพื่อเน้นจุดสำคัญ — ห้ามแก้คำ ลำดับ หรือเนื้อหาเดิม ใส่ได้แค่ tag ครอบทับ

Render ผ่าน visualize:show_widget เท่านั้น (เรียก visualize:read_me โมดูล mockup ก่อนครั้งแรกในเซสชัน) — chat ปกติไม่ render markdown/==highlight== เป็นภาพจริงเสมอไป ห้ามใช้ create_file/Artifact

เป้าหมาย: เน้นเฉพาะสิ่งที่สำคัญจริง — ใส่มากเกินไปเท่ากับไม่ได้เน้นอะไรเลย

รูปแบบ:

กฎการเลือก tag

เน้นอะไร Tag ความถี่/ย่อหน้า
command / path / ศัพท์เทคนิคเฉพาะทาง / ค่าที่ต้องตรงเป๊ะ <code> ทุกครั้งที่พบ
ประโยค/วลีที่เป็นใจความสำคัญที่สุดของย่อหน้า (คำเตือน/ข้อสรุป) <mark> 0–1
ชื่อเรื่อง/entity หลัก/คำสำคัญรอง <strong> 3–6 คำ
ชื่อสื่อ/คำต่างชาติ/คำที่กำลังนิยาม/ชื่อเฉพาะ <em> ตามเนื้อหา
อื่นๆ plain text

ลำดับเมื่อ conflict: code > mark > strong > em. อย่าซ้อน tag บนคำเดียวกันเว้นแต่จำเป็นจริงๆ

โครงสร้าง widget

<h2 class="sr-only">[สรุป 1 ประโยค]</h2>
<div style="font-family: var(--font-sans); font-size: 16px; line-height: 1.8; color: var(--text-primary);">
  ...ข้อความเดิม + <strong>, <em>,
  <code style="background: var(--surface-1); padding: 2px 6px; border-radius: 4px; font-family: var(--font-mono); font-size: 14px;">...</code>,
  <mark style="background: var(--bg-warning); color: var(--text-warning); padding: 1px 4px; border-radius: 3px;">...</mark>
</div>

ห้ามใส่หัวข้อ/คำนำ/คำอธิบายใน widget — มีแต่ข้อความ format แล้วเท่านั้น

คำขอ:

  • ห้ามแก้คำหรือเนื้อหาต้นฉบับเด็ดขาด
  • render ผ่าน widget เท่านั้น ห้ามใช้ raw markdown ในคำตอบ ห้ามเปิด Artifact
  • ก่อนเรียก widget เขียนนำสั้นๆ 1 บรรทัด (เช่น "ไฮไลต์ให้แล้วครับ") ห้ามอธิบายรายละเอียดหรือพิมพ์ข้อความซ้ำนอก widget

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.
