A drop-in Chinese-tea skill.

Give Claude or a Custom GPT authoritative knowledge of Chinese tea across 72 languages — brewing, terroir, chemistry, tasting, history, verified geographical indications and a multilingual glossary — and the b2btea.com directory of tea companies, so it answers from real data instead of guessing. Live counts are in llms.txt.

Claude (Desktop / Cowork)

Download chinese-tea-knowledge.skill.
Install it — open the .skill file (or drop it into your skills folder). It triggers on tea questions automatically.
The skill calls the public API (free, English). For 7 / 72 languages, it can send a paid key (Authorization: Bearer tt_…) — get one on the pricing page.

Prefer no install? The same thing is also a live MCP server.

Custom GPT / GPT Action (OpenAI)

Create a GPT → Configure → Actions → Import from URL: https://api.thetea.app/openapi.yaml
Paste the instructions from SKILL.md into the GPT's system prompt.
No auth needed for the free tier; add a Bearer key in the Action's auth for paid languages.
