    Figma opens code layers to all users in open beta with agent-driven prototyping workflow

    Figma's code layers feature is now in open beta for 100% of users, letting teams build and compare code-backed prototypes directly on the Figma canvas. The walkthrough shows a designer cloning a GitHub repository into a code layer, prompting the Figma agent to generate three delivery-address variations side by side, and refining one in the full-screen code editor. Extract designs turns screens or recorded flows into editable design layers that can be sent back to the prototype with Update code layer, and the agent can merge two teammates' code layers into one combined experience.

    Meta details production deployment of Catching JiTTests with human-on-the-loop review

    Meta has moved Catching JiTTests, its LLM-based just-in-time test generation approach, from research prototype into production infrastructure, and published the results in the FSE 2026 paper "Just-in-Time Catching Test Generation at Meta." The system runs overnight on spare capacity, targets risky diffs, generates tests through dodgy-diff and intent-aware workflows, and filters false positives with an LLM-as-Judge ensemble plus a rule-based RubFake assessor before reaching engineers. As of writing, 589 engineers (64% of outreach) engaged with the results, which showed a 60% true-positive rate, and in the first half of 2026 the system caught 74 serious privacy bugs at the diff stage and lowered privacy SEVs by 20%.

    Ethan Mollick's opinionated guide to which AI to use for real work

    Ethan Mollick published an opinionated guide arguing that using AI now means running agentic systems that combine a model with tools, not just chatting with a chatbot. He recommends ChatGPT (Work and Codex modes) or Claude (Cowork and Code modes) at $20/month for real work, starting with GPT-5.6 Sol or Fable/Opus at High thinking levels, and keeping approval prompts on to guard against prompt injection. He also says Google currently has no leading frontier model or Codex/Code equivalent, though Gemini Notebook and Gemini Omni remain useful for research and video editing.

    How I Polish Software That Agents Built

    Kieran Klaassen describes "polish," the final step of his compound engineering workflow, where he runs the app himself and tells the agent what feels off until it doesn't. Using the /ce-polish command from the compound engineering plugin, he checks out a branch, starts the dev server, and opens the running app beside the agent in his editor. He cites a Cora email card animation that passed all automated checks and review agents but still slid in from the top of the screen instead of opening from the click point.
