EXP-04 · AI automation
A bot that survives its sources
A Telegram bot that gathers cultural events from websites and Instagram, understands text and voice messages, and recommends plans through an AI agent with a local Córdoba tone.
Question
Can a Telegram bot keep recommending events when the websites it scrapes break?
Problem
Córdoba's cultural agenda is scattered across many websites and Instagram accounts, so finding something to do takes time.
Data
Real sources: 4 websites (Córdoba Tourism, the provincial and municipal culture agendas, and La Voz newspaper) and 13 Instagram accounts of theaters, museums and venues. No events are made up: when data is incomplete, the bot says so.
Method
A 41-node workflow with multi-source scraping (HTTP and Apify), audio transcription with Groq, a Gemini agent with memory, intent detection, LLM output validation with fallback, source schema versioning, and a separate error workflow with Google Sheets logs, admin alerts and a /metrics command.
Result
A production bot that keeps working when a source goes down; format changes are logged as SCHEMA_DRIFT and alert the admin.
What I learned
Design for degradation: fall back, log every failure, alert a human.
