Effective bots don’t just automate — they integrate. At Mozilla, we built bots that help developers do more with less friction, but the path to getting there involved far more than just scripting tasks. This talk focuses on what it really takes to build useful bots in software engineering: understanding human workflows, designing with context, and adding guardrails to avoid disasters. If you’ve ever shipped a bot that got ignored (or caused chaos), this keynote shares hard-earned lessons from the field — what works, what doesn’t, and why.
