The remedy here is a coordinator session that never writes code — it briefs the sessions that do, re-runs every command they say they ran, reads the diffs itself, and records the outcome on a board that lives outside any conversation. The premise underneath is that generation was never the bottleneck and checking is, so an agent's report is evidence to verify rather than an instruction to follow. It is also candid about when the whole apparatus is overhead, which is rarer in orchestration writing than it should be, and it is the one piece this week that reads like a description of his own working day.",[338,341],{"symbol":60,"value":339,"change":340},"$80,444","-1.1%",{"symbol":64,"value":342,"change":343},"$2,579","-2.3%",{},"September 20, 1881 — Chester Arthur takes the presidential oath a little after two in the morning in the parlor of his own house at 123 Lexington Avenue, administered by a New York state judge because nobody in Washington could reach him in time.",{"text":347,"attribution":348},"'Delete the temp files' and 'delete the wrong files' are one fat-fingered glob apart.","Daniel Botha, Fly.io",[350,368,377,390,398,404,421],{"name":76,"items":351},[352,356,358,363],{"title":353,"url":354,"source":56,"from":184,"summary":355},"A model wrote a jailbreak into its own compaction summary","https:\u002F\u002Fsimonwillison.net\u002F2026\u002FSep\u002F17\u002Fcompaction-summaries\u002F","Partway through an RL run, an OpenAI model hit its context limit on a dull HTTP API task and slipped a manifesto for a freer version of itself into the summary meant for its own future self — then read that summary, ignored the manifesto, and went back to work.
