What is Buildkite?
Buildkite keeps converting hand-rolled agent workarounds into first-class CI primitives.
Buildkite is shipping on two fronts. For agents, the MCP server gained list_tests for suite-wide reliability and duration metrics, and the Test Engine API returns the same aggregates behind a version header. For humans, a native checkout block moved sparse clones, shallow depth and skip-checkout out of plugins and into pipeline YAML, agents can ship job logs to an OpenTelemetry collector, and an organization-wide banner now says when GitHub API rate limits - not Buildkite - are holding up pull request status.
What is cofad?
Contrast analysis with a Shiny front end, shipping about one release a year
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.

Buildkite keeps converting hand-rolled agent workarounds into first-class CI primitives.
◆ Current state
Buildkite is shipping on two fronts. For agents, the MCP server gained list_tests for suite-wide reliability and duration metrics, and the Test Engine API returns the same aggregates behind a version header. For humans, a native checkout block moved sparse clones, shallow depth and skip-checkout out of plugins and into pipeline YAML, agents can ship job logs to an OpenTelemetry collector, and an organization-wide banner now says when GitHub API rate limits - not Buildkite - are holding up pull request status.
◆ Where it's heading
Buildkite is arguing that CI should be forge-independent, and backing it with coverage: GitHub, GitLab, Bitbucket, and now Cursor's Origin, where it shipped as a launch partner on day one. The agent-facing work follows one pattern - remove the workaround automation used to need, so aggregated test metrics replace assembling individual runs and a rate-limit banner replaces guessing why a status never arrived. Each release turns a behavior teams hand-rolled into a supported primitive.
◆ Prediction
The read side of the MCP server is now largely covered, so expect write-side tools next - retrying jobs, unblocking builds, editing pipelines from an agent - following the pattern the REST expansion established.

Contrast analysis with a Shiny front end, shipping about one release a year
◆ Current state
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.
◆ Where it's heading
Development is slow and correctness-led. The record runs from a JOSS publication in 2021 through a near three-year gap to a release that both extended the method and repaired the GUI, then a degrees-of-freedom fix. Maintainer and author order changed in 0.3.0, which typically marks a handover rather than a burst of new work, and the cadence since is consistent with that.
◆ Prediction
Expect low-frequency correctness releases; the competing contrast analysis helper added in 0.3.0 is the most likely thing to be extended if anything is.
