What the agent does
Classifies, sorts, summarizes long threads, drafts trivial replies (never sends without my OK).
Architecture
Gmail API polling → Claude Haiku classifier → label + move → Slack alerts for urgent client mails.
Honest limits
No attachment reading without tool use, ~3% classification error, ~€3/month in tokens.
