conversely, i think most teams probably shouldn’t be building their own harness. it is unlikely you will have novel ideas around sub-agent orchestration, compaction, progressive disclosure etc that are worth owning the entire harness spend your time investing in the pieces around the harness: - execution infrastructure - custom tools, MCPs and skills - self improvement on trajectories



What’s the best way for non developers to 1. share skills with their team 2. automatically enforce that it’s always updated for everyone if changes are made 3 allow others to update it centrally Github is not the best solution as it’s too clunky and doesn’t solve #2 Notion is a little better but can’t put code there I’m tempted to create my own tools but someone surely has created this already??

NEW: Amazon researchers are reportedly behind the jailbreak report that led to the U.S. crackdown on Anthropic’s top models.








NEW: Anthropic is walking back Claude Fable 5's policy to covertly degrade performance for competing AI researchers, after facing fierce backlash. “We’re changing Fable 5’s safeguards for frontier LLM development to make them visible,” Anthropic tells WIRED. “We made the wrong tradeoff and we apologize for not getting the balance right.”

Increasingly, I believe companies may need to be rebuilt from the ground up, where you have a single timeline of all observability + product metrics + file changes laid out in a retrievable system, like Datadog + Posthog + Google Drive + Slack (really unified filesystem of Claude Code chats + Codex chats). This might be the new data foundation for any and all companies to maximize AI. Needs to be rebuilt because keeping track of diffs on existing system basically impossible to produce longitudinal information on decisions and rollbacks, something coding agent storage companies are actively trying to figure out, but this should extend to businesses as a whole. Highly skeptical existing businesses will adopt this though because it means overhauling everything about their instrumentation and business data, but I think businesses built on this foundation probably can execute 100x better and faster
