What is MotherDuck?

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

What is tern.rbmi?

Reference-based multiple imputation tables, shipping only what CRAN checks demand.

tern.rbmi renders the output of {rbmi} reference-based multiple imputation analyses into tern tables for clinical reporting. Its three most recent releases exist to satisfy CRAN: restricting vignette builds to gcc, adding V8 to Suggests, and a plain resubmission. No user-facing functionality has changed in the visible window, and the three older entries now backfilled are version-bump automation.

MotherDuck vs tern.rbmi: editorial side-by-side

6.3

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

◆ Current state

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

◆ Where it's heading

The pattern is consistent: ship an agent-facing capability, then spend the following weeks making it governable and reachable. Iceberg interoperability keeps widening — Databricks-managed tables, Cloudflare R2 as a persisted catalog, server-side attach — which positions MotherDuck as a compute engine over catalogs it does not own. The CLI extends the same logic to automation: anything the UI can do should be drivable from a script or a CI job.

◆ Prediction

Expect the CLI to leave preview with Flights and Dives management as its centre of gravity, and Guides to follow the same governance path Flights took — org-level controls, roles, and visibility rules layered on after the capability lands.

0.0

Reference-based multiple imputation tables, shipping only what CRAN checks demand.

◆ Current state

tern.rbmi renders the output of {rbmi} reference-based multiple imputation analyses into tern tables for clinical reporting. Its three most recent releases exist to satisfy CRAN: restricting vignette builds to gcc, adding V8 to Suggests, and a plain resubmission. No user-facing functionality has changed in the visible window, and the three older entries now backfilled are version-bump automation.

◆ Where it's heading

This is a thin adapter package and behaves like one — it moves when CRAN or an upstream dependency forces it to. Between 2022 and 2024 the feed shows only version bumps, and the 2025 releases are packaging concerns rather than analysis changes. The newly surfaced 2022 entries reinforce rather than change that reading.

◆ Prediction

Expect the next release to be triggered by a CRAN check failure or an {rbmi} update rather than by new tabulation features.
