What is Buildkite?

Buildkite is rebuilding CI as something agents drive, not just humans.

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

What is cocoon?

A statistics-formatting helper in maintenance mode, tracking R-devel one fix at a time

cocoon formats statistical output for manuscripts, converting model and test objects into publication-ready strings. Its surface settled early: format_stats() is a generic that dispatches on object class, introduced in 0.1.0 to supersede the earlier format_corr() and format_ttest(), and extended in 0.2.0 to cover aov, lm, glm and the lme4 and lmerTest mixed-model families. The two releases since have been single-issue compatibility fixes against changes to wilcox.test() in R-devel.

Buildkite is rebuilding CI as something agents drive, not just humans.

◆ Current state

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

◆ Where it's heading

Buildkite is arguing that CI should be forge-independent, and it is now backing that with coverage: GitHub, GitLab, Bitbucket, and as of this week Cursor's Origin, where it shipped as a launch partner on day one. On the agent side the pattern is removing the workarounds automation used to need - a wait tool instead of a polling loop, aggregated test metrics instead of assembling individual runs, an early failure signal instead of waiting for a job to exit. Each release converts a hand-rolled agent behavior into a first-class primitive.

◆ Prediction

The read side of the MCP server is now largely covered, so expect write-side tools next - retrying jobs, unblocking builds, creating or editing pipelines from an agent - following the same pattern the REST expansion just established.

A statistics-formatting helper in maintenance mode, tracking R-devel one fix at a time

◆ Current state

cocoon formats statistical output for manuscripts, converting model and test objects into publication-ready strings. Its surface settled early: format_stats() is a generic that dispatches on object class, introduced in 0.1.0 to supersede the earlier format_corr() and format_ttest(), and extended in 0.2.0 to cover aov, lm, glm and the lme4 and lmerTest mixed-model families. The two releases since have been single-issue compatibility fixes against changes to wilcox.test() in R-devel.

◆ Where it's heading

The package reached feature completeness for its stated job quickly and has been in maintenance since early 2025. Both 0.2.1 and 0.3.1 address the same upstream moving part - how wilcox.test() computes exact versus asymptotic distributions in development versions of R - which is the shape of a package whose own code is stable and whose risk lives entirely in what it wraps. Nothing in the recent entries points at new statistical object types.

◆ Prediction

Further releases are likely to stay reactive, triggered by R-devel or dependency changes rather than by new formatting methods, unless a specific model class is requested.
