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 phyloatlas?

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

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.

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

◆ Current state

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Where it's heading

The project's defining decision is that it archives the recipe rather than the corpus. Since 1.0.3 the Zenodo deposit holds metadata, provenance, and standardization code while the tree files live at their original sources, and the same principle was applied again when the TimeTree-of-Life was removed at the TimeTree project's request and reduced to a citation. What makes the correction log unusual is its direction: partitions keep getting reclassified from dated to undated as verification confirms the source papers described chronograms they never deposited. The atlas is being built to be honest about archival uncertainty rather than to maximize coverage.

◆ Prediction

The release cadence is driven by the manuscript review cycle, so expect corrections to continue until MEE acceptance and then slow sharply; the open thread most likely to produce the next one is the remaining recoverable archival uncertainty flagged across non-Condamine dated source trees.
