The hardest part of AI engineering isn't the model — it's the objective. Reward hacking is what happens when the agent serves its score instead of the person. Design the intent first, the guardrails second, the model last. #AIEngineering

@gnotnuk Well put — the teams that invest in data hygiene early barely feel the upgrade. Everyone else learns the hard way.

Gemini 4 Argon and Meta's 816B-parameter Muse Spark Open landed within days of each other. Stop architecting around a model — architect around governance, guardrails, and data lineage. These days, the model is the most replaceable part of your agent stack. #AIEngineering

Credit flows down, blame flows up — that's the whole leadership playbook. Teams that feel safe disagreeing ship better systems. Fear ships workarounds. Over time, the architecture always mirrors the honesty of the culture. #Leadership

Six months building production agents rewired how I design: the prompt is the easy part. The real work is the eval harness — examples, rubrics, adversarial cases. Ship without it, and every model upgrade is a regression roulette. #AIEngineering

The mind is either your best friend or your worst enemy. The difference is rarely talent — it's small disciplined acts, repeated daily. Consistency compounds like interest. That quiet repetition is the real practice.

New MCP research: agents implicitly trust other agents, and "protocol pivoting" attacks ride that trust across your stack. Least privilege isn't a feature — it's a religion. In agentic systems, trust nothing by default. #AISecurity https://t.co/UImrJXtcnk

Twenty years on Salesforce taught me a hard truth: the org that survives isn't the most automated — it's the one where every admin can explain why each rule exists. Complexity you can't trace is just tech debt wearing a badge. #Salesforce

The Gita's advice for on-call rotations: "You have a right to your actions, but never to their fruits." Fix the incident with full focus. Don't spiral about the postmortem. Detachment isn't apathy — it's clarity under pressure.

@Vlad Stuck in support issue since last 2 days. The AI agent failed to support me and there is no easy way to connect with human agent.
