What is Expo?
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.
What is Gatekeeper?
Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.

Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Gatekeeper
2.5INFRA · APIS
Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
◆ Current state
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.
◆ Where it's heading
The centre of gravity is moving from the admission controller to the tooling around it. Policies are becoming artefacts you install from a library at a version, benchmark against a baseline in CI, and test before they reach a cluster — which is the lifecycle application code already has and policy generally has not. Underneath, the ValidatingAdmissionPolicy path keeps maturing as Gatekeeper hands more enforcement to the Kubernetes-native mechanism it now generates.
◆ Prediction
Remote cluster mode gained status routing but the entries describe only that piece, so how far multi-cluster enforcement extends is unclear from these notes. The releases in this window are all beta and release candidates, so a 3.24.0 stable is the near-term milestone.
