What is asar?
A NOAA report-template generator being debugged by the workshops that teach it.
asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.
What is Expo?
Expo shut down its own agent and is wiring itself into the ones developers already use.
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.

◆ Current state
asar generates standardized stock assessment report skeletons, with create_template() as the function everything else orbits. The visible release history is short and entirely reactive: two rounds of fixes to template customization and rerendering, then a documentation release moving the project's authoring guidelines onto the package website as living articles. Nothing in the window adds capability.
◆ Where it's heading
The releases are paced by training events rather than a roadmap. The 2.0.0 rerender bugs — blank author sections, parameters not propagating into both the YAML and the params chunk, custom sections mislabelled — are the kind found by people actually filling in a template, and the follow-up hotfix names a workshop explicitly as where the problems surfaced. Moving the guidelines into versioned site articles, revised after workshop feedback, continues that: the standard is being treated as part of the software rather than a document beside it.
◆ Prediction
With a workshop series named as upcoming in the entries, the next release is most likely another round of template fixes reported from a live session rather than new report types.
Expo
6.3INFRA · APIS
Expo shut down its own agent and is wiring itself into the ones developers already use.
◆ Current state
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.
◆ Where it's heading
The pattern is conceding the assistant layer and defending the build, test, and deploy pipeline underneath it. Instead of competing for the agent surface, Expo is making project data reachable from whichever assistant a developer already runs — the free MCP server first, now a Claude desktop connection. EAS meanwhile keeps absorbing more of the release pipeline: observability heading to GA, end-to-end test insights, device provisioning automated.
◆ Prediction
More connector and MCP surface for other assistant hosts is the likely next step, alongside EAS work around what is already in flight — particularly Observe once it reaches GA on August 20. The entries give no indication of whether the SDK release cadence changes as a result.
