Chi Wang(@Chi_Wang_):Anthropic says the new cyber safeguards in Fable 5.1 cut false positives 60%, and Claude Code users see about 60% fewer safety interventions per session versus Fable 5. That's a throughput number, not just a safety number. Every false-positive block ends an autonomous coding session and pulls a human back in. Halving the interruption rate is what actually lets you leave an agent running unsupervised for longer, independent of any capability gain.
