What is thai-business-registration?

A decision guide for choosing a Thai business registration type, such as a sole proprietorship, partnership, company, or BOI route.

Use it to compare registration options, consider the 1.8-million-baht VAT threshold and one-employee social-security threshold, and assess BOI-related cases.

It helps match the registration choice to revenue, partners, liability needs, tax and employee thresholds, and accounting obligations.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00073	$0.02198
Opus 5	$0.00036	$0.01099
Sonnet 5	$0.00015	$0.00440
Haiku 4.5	$0.00007	$0.00220

Security

Grade A, and why

thai-business-registration 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 12d 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.

Thai Business Registration — Decision Tree

Mistake ที่ที่ปรึกษามือใหม่ทำบ่อยที่สุด: แนะนำ "จดบริษัทเลย" ทุกเคส. จริงๆ ลูกค้าที่รายได้ปีแรก 800k-1.6M ควรอยู่ ทะเบียนพาณิชย์ (sole proprietorship) — ประหยัดค่าทำบัญชี + ผู้สอบบัญชี 60-80k/ปี.

thai-business-registration ให้ Claude เดิน decision tree ตาม revenue, จำนวนหุ้นส่วน, และความต้องการ limited liability.

เมื่อ Claude เห็นคำขอแบบนี้

จดบริษัทดีไหม รายได้ปีนี้จะแตะ 1.6M ทำคนเดียว

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.
