What the Buildkite integration adds

Buildkite supplies detailed build output while Unblocked supplies the surrounding code and pull-request history. The CI Failure Agent combines those inputs to turn a failed build into a concise, confidence-gated explanation at the point where the change is being reviewed.

Because Unblocked already understands your codebase, pull requests, and team discussions, its analysis is grounded in that context — it explains what broke and suggests a fix, with links back to the relevant code and history.

Buildkite connects with a read-only API token plus a build-finished webhook, so Unblocked is notified the moment a build fails. Reports post as a comment on the pull request and are gated by confidence.

What you get

• Build-log failure analysis — The CI Failure Agent reads your Buildkite build logs and analyzes failures across pipelines to find the root cause.
• Root-cause reports on the PR — When confident, Unblocked posts a comment on the pull request explaining the failure and suggesting a fix.
• Grounded in your codebase — Analysis draws on your indexed code, pull requests, and discussions, so suggestions fit how your project actually works.
• Confidence-gated, per-developer control — Reports post only when Unblocked is highly confident, and each developer can toggle them for their own PRs in Personal Settings → Preferences.
