Theo’s reusable coding-agent skills distinguish delegation through merge from stopping at a review-ready pull request. His practitioner account highlights explicit permissions, bounded review, and verification, but does not establish general reliability gains.
Eon’s Era benchmark shows a sharp gap between simple record filtering and multi-hop enterprise tasks. Its coherent simulated companies make failures checkable, though the developer-reported comparison covers only one company and 33 questions.

Moonshot’s cybersecurity disclosure shows why stronger general coding ability complicates attempts to limit offensive capability before opening access.

Its central test is whether proactive assistance saves more attention than supervision consumes, within shared usage limits.
https://techcrunch.com/2026/10/22/claude-duet-app-is-anthropics-bet-on-agents/ Simon Willison’s Battle Drones and its next-day French steampunk fork show how AI-assisted games can become material for others to reshape. The development history also shows why playtesting and human judgment still matter, even when little code is reviewed.

https://biohub.org/news/virtual-biology-initiative-expansion/?ref=cognitiverevolution.ai Theo argues that some feature requests are better handled as one-off agent tasks, while engineering effort goes into reusable data access, tools, and controls. His T3 Code examples illustrate a product-design approach, not proof that conversational workflows are universally better.
