Agent Canvas Draw adds real-time whiteboarding

A developer pattern for the Vercel AI SDK that integrates Excalidraw into chat interfaces, allowing AI agents to generate, stream, and manipulate visual diagrams in real-time. It transforms AI chat from a text-only exchange into a collaborative visual workspace.

// ANALYSIS

This pattern marks a critical shift from text-only reasoning to spatial collaboration in AI agent interfaces.

–Excalidraw integration provides a polished, hand-drawn aesthetic that's perfect for system architecture, user flows, and org charts.
–Real-time delta streaming allows users to watch the agent "draw" its thoughts, creating a more interactive and transparent UX than static image generation.
–Standardizes visual "Canvas-mode" for Next.js developers using the Vercel AI SDK and shadcn/ui.
–Support for SVG, PNG, and raw Excalidraw exports makes it a functional tool for professional design and research agents.
–Demonstrates the growing trend of "artifact-driven" AI UX, where the chat is just one part of a larger, persistent workspace.

UserHarness reframes Theory of Mind as user-mind reconstruction

UserHarness is an inference-time framework for Theory-of-Mind tasks that models a user’s partial observations, evolving beliefs, intentions, and actions instead of inferring mental state indirectly. In the paper, the approach is evaluated across five benchmarks and reaches up to 95.94% macro accuracy, with reported gains of more than 15% relative over existing inference methods and about 20% relative over the strongest prompt-only harness.

Claude Code adds dynamic workflows with Ultracode mode

Anthropic’s latest Claude Code update adds dynamic workflows that let Claude plan work, fan tasks out across parallel subagents, verify results, and return a single coordinated answer. The new `ultracode` setting raises effort automatically and lets Claude decide when to use the workflow mode, targeting large debugging, codebase migrations, security audits, and other long-running engineering jobs.

Loblaw says Codex cuts build times

Loblaw’s Chief Digital Officer says Codex is shrinking engineering work that used to take teams weeks into minutes or hours, while also speeding e-commerce content creation. The video is a fresh enterprise case study for OpenAI’s coding agent, not a launch announcement.
