Generation got cheap; coherence, tool prose, and operational limits got expensive
- Cheap Prototypes and Incoherent Products: The Winchester Mystery House ProblemThe Winchester Mystery House is usually told as a ghost story. Sarah Winchester, heiress to the rifle fortune, building endlessly to appease the spirits of the people her family's product killed — staircases that climb i…
- Design Systems Become Auditable Agent Contracts, Not Figma LibrariesIn the Expo design-system package inside OpenDesign's repository, the token `--bg` is not recorded as `#ffffff`. It's recorded as `#ffffff` — with a source: `tokens.css:8`.
- WebMCP in the Wild: Tool Descriptions Become the Craft SurfaceWatch the confidence numbers while you type "gluten free" into a Chrome side panel. They move mid-word.
- The Hidden Tax: Quotas, Context Re-reads, and Unbounded Agent RunsThe conventional wisdom says to fetch a lightweight outline of a Figma file first, then pull styling only for the components you actually need. It sounds efficient. It's the kind of advice a senior engineer nods along to…
- Orchestration Is the Product as the Model Layer CommoditizesThe most-adopted AI design agent in the Figma plugin market does not have a model. Lovart publishes no parameter counts, no training-data volumes, no inference-latency benchmarks, and its repository contains no PyTorch t…
Threads we are following
- Whether teams will adopt shared object models and interaction patterns before AI-generated features outpace their design systems.
- How teams will maintain source-backed token contracts when stylesheets, agents, and design tools change independently.
- Whether the WebMCP working group will formalize a precise 'consequential' threshold for human confirmation.
- How Figma's per-user, per-plan quota model will adapt to shared OAuth and personal access tokens in multi-agent design workflows.
- Whether orchestration-layer advantages remain defensible as frontier labs bundle routing and agentic coordination into their own platforms.
