17 minutesDefending LLM - Prompt Injection
Review prompt-injection defenses such as taint analysis, output-shape restrictions, user isolation, deterministic settings and redundant checks for critical paths.
Watch nextFireship. The clearest short explanation on YouTube of the screenshot–action–screenshot loop, including the honest failure modes (Claude wandering off to look at Yellowstone, token burn, latency per step). Fireship is light on production detail by design — read the article for that — but it leaves you with the right intuition for why these systems are expensive and brittle before you commit one to your stack.
Keep this as intuition-building, not production guidance. The video intentionally compresses the topic; production systems need sandboxing, secrets isolation, audit logs, rate limits and rollback paths.
Understand why screenshot-based computer use is powerful, slow, expensive and brittle compared with API-native automation.
Know the difference between an LLM calling an API tool and an LLM controlling a browser or desktop.
