Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
Expo is at a turning point: the EAS infrastructure layer — build, update, and now observe — is maturing into production-grade tooling, with EAS Observe reaching GA in August and SDK 58 entering beta this week. Simultaneously, Expo shut down its AI Agent experiment after months in closed beta, a signal that building an AI coding assistant directly on the platform didn't reach product-market fit. The MCP server and Claude desktop integration indicate where the AI bet now sits: in connectors, not agents.
FullStory's release feed is empty — no usable signal in the changelog stream.
The only captured entry is navigation chrome ('Follow us') with no release content. This means our scraper isn't finding FullStory's actual changelog or that releases aren't being published in a machine-readable form on the public surface we monitor.

Expo is consolidating around EAS as an observable infrastructure layer, not as an AI product builder. The MCP server and third-party integrations (PostHog, Claude) suggest the strategy is to serve as a data and build substrate that AI tools operate on top of. SDK 58 will push new device capabilities through the standard pipeline; EAS Observe data becoming a programmable surface for AI tools is the natural next extension of this approach.
The next move is a stable SDK 58 release and deeper AI-tool integrations via MCP — Expo is betting its AI story on being the substrate that coding assistants operate on, not on shipping its own. Expect more one-command observability integrations to follow PostHog.

Trajectory cannot be assessed from the available data. The scraper either needs a different source URL or FullStory has shifted release communication elsewhere (in-product, customer portal, or blog-only).
Until a new source is wired in, no prediction is possible. Worth flagging this product for source-discovery work rather than commentary.
