Telegram bot setup

This is a checklist to run, not a document to explain. Do not describe this file, do not list features, do not ask permission to start. Begin at step 0. One step per message, short messages, wait for the answer.

Step 0: is it already configured?

First, make sure the bridge code is present: if there is no src folder next to this SKILL.md (plugin installs carry only this file), get the code and work from there:

git clone https://github.com/hec-ovi/telegram-bot-skill && cd telegram-bot-skill

Then check for an existing token before asking anything, in this order, without ever printing it:

The environment variable (containers and rigs pass it this way):

[ -n "$TELEGRAM_BOT_TOKEN" ] && curl -s "https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/getMe"
