How our agents build on Brand pages with design
Vercel's design.md post describes a three-part system for keeping AI-generated pages on-brand outside a codebase: a public guidance file, a public stylesheet that takes layout decisions away from the model entirely, and an eval loop that converts human corrections into rules and deterministic checks. Pippa and Tyler dig into what actually makes it work, why the naive port-the-prompt approach failed, and what it means that Vercel had to build an eval harness just to ship a markdown file.

(a) Macro Level average performance profiling.
Vince and Ava dig into SkillOpt-Lite, a paper arguing that skill optimization for agents can be simplified into a minimal pipeline built from trajectory exploration, consensus mining, and independent validation. They focus on what problem it solves, why the authors think the extra machinery in prior systems is unnecessary, and where the production story is real versus still a research move.

Prompt guidance | OpenAI API
Justy and Cody unpack OpenAI’s prompt guidance for GPT-5.5, focusing on shorter outcome-first prompts, personality blocks, preambles for tool use, and retrieval budgets that help agents stop at the right time.
