AGENTS.md

claude-thai-business-skills AGENTS.md is an instructions file for Codex, OpenCode from Boom-Vitt/claude-thai-business-skills. It costs 949 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents working on a set of Claude Code skills for Thai small and medium-sized businesses. They describe the required context, file structure, language, financial units, Thai laws and markets, and development checks.

In plain words
What is it for?
Use them when creating or changing skills for Thai business owners, advisers, or analysts, especially work involving Thai taxes, privacy law, marketplaces, financial calculations, or helper code.
Why use it?
They prevent an agent from applying unsuitable foreign assumptions, using the wrong language or currency, or skipping the repository’s validation and testing rules.

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

claude-thai-business-skills AGENTS.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 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.

AGENTS.md — คู่มือ AI agents

ไฟล์นี้สำหรับ AI agent (Claude Code, Cursor, Codex, Gemini CLI, …) ที่จะมาทำงานในรีโปนี้.

บริบท / Context

รีโปนี้เป็นชุด Claude Code skills สำหรับงานที่ปรึกษา SME ไทย. แต่ละ skill อยู่ใน skills/<name>/ พร้อม SKILL.md (frontmatter + คำแนะนำ) และ optional helper code.

ผู้ใช้ปลายทาง: founder/CEO ของ SME ไทย, ที่ปรึกษาที่ดูแล SME, นักวิเคราะห์ที่ทำงานในบริบทไทย. ไม่ใช่ดีเวลอปเปอร์ฝรั่ง. ทุก output ต้อง:

  • ภาษาไทยเป็นหลัก (พร้อมศัพท์ภาษาอังกฤษเมื่อมาตรฐานต้องการ เช่น VAT, WHT, P&L, CAC, LTV)
  • ตัวเลขเป็น THB เว้นแต่จะระบุ
  • กฎหมาย/ภาษีอ้างอิงไทย (ประมวลรัษฎากร, PDPA, BOI, DBD) ไม่ใช่ US/EU
  • ตลาดอ้างอิงไทย (Shopee TH, Lazada TH, TikTok Shop TH, LINE Shopping, FB Shop TH)

วิธีทำงานในรีโปนี้ / How to work here

  1. อ่าน template/SKILL.md ก่อนสร้าง skill ใหม่
  2. รัน ./scripts/validate-skills.py หลังแก้ frontmatter เพื่อเช็คโครงสร้าง
  3. รัน ./scripts/test-all.sh ก่อน commit
  4. ทุก skill ต้องมี self-test ถ้ามี helper code (.py / .ts)
  5. ใช้ Decimal ไม่ใช่ float ในทุกการคำนวนเงิน — เคยมีบั๊กตอน VAT 7% บน 33.33฿
  6. อย่าเดา marketplace fee — copy benchmark จาก skills/<name>/benchmarks.md แล้วระบุ "อ้างอิงปี 2026"

โครงสร้าง SKILL.md

ทุก SKILL.md เริ่มด้วย frontmatter YAML:

---
name: thai-something
description: หนึ่งบรรทัด ตอบคำถาม "skill นี้ใช้ทำอะไร" — Claude เอาไปจับ intent
when_to_use:
  - เคสที่ skill นี้ตอบโจทย์ (1)
  - เคสที่ skill นี้ตอบโจทย์ (2)
when_not_to_use:
  - เคสที่ skill นี้ไม่เหมาะ
version: 0.1.0
last_verified: 2026-05-19
tier: validator | reference | prose
---

จากนั้นเป็น Markdown body — แนะนำ Claude ทีละขั้น. ดูตัวอย่างใน skills/thai-pricing-strategy/SKILL.md.

ทุกครั้งที่กฎหมายเปลี่ยน อัปเดต last_verified: ใน frontmatter และเพิ่ม entry ใน CHANGELOG.md.

  • Corporate income tax (SME) — 2026: <300k = 0%, 300k-3M = 15%, >3M = 20% (ทุนชำระ ≤5M, รายได้ ≤30M)
  • VAT threshold — 2026: 1.8M฿/ปี (ตามมาตรา 81/1)
  • WHT talent fee — 2026: 3% (ไทย), 5% (ต่างชาติ resident), 15% (non-resident)
  • SSO contribution — 2026: 5% นายจ้าง + 5% ลูกจ้าง, cap ที่ฐาน 15,000฿/เดือน
  • Marketplace fees — Shopee Mall 5-8%, Lazada Mall 5-7%, TikTok Shop 1-8%, LINE Shopping 3-5% (ปี 2026)

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.
