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 daedalus?

An epidemic-economic model teaching its interventions to react to the outbreak itself.

daedalus couples an infectious-disease model to sector-level economic costs, letting users test non-pharmaceutical interventions against both epidemic and fiscal outcomes. Over autumn 2025 the intervention layer went from a single fixed closure to sequential timed NPIs and then to closures that lift in response to the model's own instantaneous reproduction number. Alongside that, the cost functions were reworked so illness states map more carefully onto lost productivity.

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.

An epidemic-economic model teaching its interventions to react to the outbreak itself.

◆ Current state

daedalus couples an infectious-disease model to sector-level economic costs, letting users test non-pharmaceutical interventions against both epidemic and fiscal outcomes. Over autumn 2025 the intervention layer went from a single fixed closure to sequential timed NPIs and then to closures that lift in response to the model's own instantaneous reproduction number. Alongside that, the cost functions were reworked so illness states map more carefully onto lost productivity.

◆ Where it's heading

The arc is toward a model that behaves like a policy simulator rather than a scenario calculator: interventions now have their own state machine, R_t is computed inside the ODE system, and event handling has been pulled out of the output object. Correction releases sit between the feature ones, including an indexing fix the maintainers flag as required for accurate projections. The versioning is patch-level but the changes are structural.

◆ Prediction

With R_t and the next-generation matrix now available in-model, the likely next step is richer response rules keyed to those quantities; the entries give no signal on when a stable 1.0 arrives.
