Claude Code's new Mods system lets developers rewrite the AI coding tool from the inside
Anthropic is adding a "Mods" system to Claude Code, essentially middleware that runs directly inside the tool. Developers can use JavaScript or TypeScript to reshape the interface and behavior, adding custom panels, intercepting tool calls, or wiring up new commands.
AI agents build 3D scenes from photos but have no idea if they got it right
A new approach called LEGO-Anything turns single photos into editable Blender code for 3D scenes. GPT-6 Astra leads the accompanying benchmark with up to 53 percent reconstruction accuracy. The biggest weakness across all tested agents is that they can't judge their own geometric accuracy any better than a coin flip.

Quoting voxium
An engineer half a month into a new role at a big company says the team's specs, code, tests, PRDs, tickets and their resolution, reports and more are all generated by Claude Code. Nobody on the team likes it, but they are being forced to ship as much as they can. He says he has heard multiple times from higher management that pushing code is not a bottleneck, and that people work 12 to 13 hours a day just to press enter, with everyone from L1 to L7 engineers doing the same thing and nobody reading anything.
