+name: ci-fails-buildkite
+description: Fetch and diagnose vLLM Buildkite CI failure logs. Use when investigating failing CI jobs on a PR or build, when the user pastes a buildkite.com URL, or asks to fetch/diagnose CI logs.
+---
+
+# Diagnosing vLLM Buildkite CI Failures
+
+Buildkite logs are public; no login needed.
+
+`.buildkite/scripts/ci-fetch-log.sh` saves each log as `ci-<build>-<job-name>.log`, stripped of timestamps and ANSI codes. Existing files are kept; set `CI_FETCH_LOG_FORCE=1` to refetch.
+
+## Fetching logs
+
+```bash
+# All failed jobs in a PR's latest build (current branch's PR if omitted):
+.buildkite/scripts/ci-fetch-log.sh --pr <PR>
+
+# All failed jobs in a build (--soft also includes soft-failed jobs;
+# --all fetches every finished job):
+.buildkite/scripts/ci-fetch-log.sh "https://buildkite.com/vllm/ci/builds/<N>"
+
+# One job — `gh pr checks` URLs (#<job_uuid>) and web UI URLs (?sid=) both
+# work; pass "-" as a second argument to stream to stdout:
+.buildkite/scripts/ci-fetch-log.sh "https://buildkite.com/vllm/ci/builds/<N>#<job_uuid>"
+```
+
+To clean an already-downloaded log with `.buildkite/scripts/ci-clean-log.sh`:
+
+```bash
+./ci-clean-log.sh ci.log
+```
+
+## Reference
+
+See [docs/contributing/ci/failures.md](../../../docs/contributing/ci/failures.md) for the full guide: filing CI failure issues, investigating/bisecting, reproducing flaky tests, and daily triage.
