What is MachineShop?
A mature R modelling framework refining variable importance and resampling controls
MachineShop provides a unified interface over a wide set of R model packages, handling fitting, resampling, performance metrics and variable importance behind one API. Recent releases are narrow and mostly corrective: 3.9.2 removed dead documentation links and fixed a Java parameter in a BART example, 3.9.1 ensured global settings reach compute nodes when varimp() runs in parallel and patched XGBoost model compatibility. The last release with real surface change was 3.9.0, which added offset support to XGBModel and a pool argument to calibration() controlling whether calibration curves are computed on pooled predictions or averaged across resampling iterations.
What is WorkOS?
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ Current state
MachineShop provides a unified interface over a wide set of R model packages, handling fitting, resampling, performance metrics and variable importance behind one API. Recent releases are narrow and mostly corrective: 3.9.2 removed dead documentation links and fixed a Java parameter in a BART example, 3.9.1 ensured global settings reach compute nodes when varimp() runs in parallel and patched XGBoost model compatibility. The last release with real surface change was 3.9.0, which added offset support to XGBModel and a pool argument to calibration() controlling whether calibration curves are computed on pooled predictions or averaged across resampling iterations.
◆ Where it's heading
Development has concentrated on variable importance and resampling rather than on adding models. 3.8.0 restructured the VariableImportance class to record which method and metric produced it, with an update() method to migrate objects from earlier versions, and extended term-specific p-values to Cox, POLR and survival regression models. 3.7.0 added grouped and stratified resampling to the control objects. The pace has slowed markedly - four releases in the last two years against six in the two before - and the recent content is compatibility work against XGBoost, parsnip, ggplot2 and recipes.
◆ Prediction
Expect the deprecated calibration pooling behaviour to be removed in a future release as the notes state, with the intervening versions continuing to track upstream model package changes.
WorkOS
8.8INFRA · APIS
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
◆ Current state
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
◆ Where it's heading
The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
◆ Prediction
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
