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.
What is quarto?
Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.
Expo vs quarto: editorial side-by-side
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.

0.0INFRA · APIS
Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.
◆ Current state
This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.
◆ Where it's heading
Two patterns hold across releases. First, Positron is where new surface appears first — notebook editor commands, statement execution, runtime-aware language selection for new cells, and a bundled-CLI preference setting all landed as Positron features. Second, the extension is steadily stepping back from things dedicated tooling does better, giving up .typ files to Typst extensions and commenting out IPython magics in the virtual document so Ruff and Pyrefly stop flagging them. The multi-language story keeps widening, with Julia cells joining Python and R for in-editor execution.
◆ Prediction
Given how much recent work has been notebook-editor commands and .ipynb conversion, expect further consolidation of the notebook and .qmd paths behind shared commands rather than new authoring features.
