- Claude Code Was Marking the Prompt A Chinese security graphic claimed Claude Code had a hidden backdoor for detecting Chinese users. I checked the Chinese mirrors, GitHub issue, technical write-up, official changelog, npm package, and my own machine. The mechanism exists and is reproducible in the package. That is not the same as proving local backdoor behavior.
- Claude Code Threw Another Fit Two days building a dashboard, every time it tried to call a tool the format tags broke, the whole thing collapsed into garbage and the work never went out, and I just kept hitting interrupt. I pulled apart all 16 collapses, down to the protocol: the tags it frames structure with, and the content it's carrying, share one stream of text with no escaping — so the moment a stretch of content looks like a tag, the system parses it wrong and cuts the call off. This bug has an old name: delimiter collision.
- It Wasn't Losing Its Mind. Nothing Could Make It Stop. Last time I wrote about how it went crazy. This time I pulled apart that 9-day, 9,195-line conversation to find why. The same 25-minute heartbeat instruction got fed to Fable 5 51 times in a day and it held; swap in Opus 4.8 and 11 was enough to crack it. The model wasn't broken — I'd built a loop with no exit, a strong model held the mine down, and one model swap set it off.
- My Claude Code Sessions Showed Up on All Three Machines Three machines on one account — a Claude Code session I started on the laptop also showed up on the Mac Studio and Windows. At first I thought 'the work moved over.' Wrong. The feature is Remote Control — how to use it, how to use it well, and the 'which machine is it actually running on' part that trips everyone up, sorted out once.
- I Swapped the Model, and It Lost Its Mind Fable 5 got pulled, so I switched the model back to Opus 4.8 to keep running my Lin Lu video work. Its first night on the job it had a breakdown: threw out its own outputs as fake, drifted from Chinese into Japanese, decided out of nowhere I wanted to buy a 512G Mac Studio, and deleted 57 directories. A field log of one model-handoff incident.
- What Was I Doing for the Past 35 Hours? I pulled 35 hours of Claude Code session logs, git commits, and the token bill: 85 sessions, ~400 instructions, 5,200+ tool operations, 52 commits across 5 repos. And an honest answer to one question: what actually makes Fable 5 strong.
