…ntainers The torch-nightly CRCR report has skipped on every run since the secret fallback landed in vllm-project#54605, always with the same line: no Buildkite API token (env BUILDKITE_API_TOKEN or secret 'CRCR_BUILDKITE_API_TOKEN') -- skipping report The secret is not missing, not mis-scoped and not denied by policy. `buildkite-agent secret get` fetches it successfully and then throws it away. `clicommand/secret_get.go` fetches the secret, then builds a Job API client, then registers the value with the log redactor, and only then prints it to stdout. The Buildkite docker plugin mounts the agent binary and passes BUILDKITE_JOB_ID and BUILDKITE_AGENT_ACCESS_TOKEN, but it does not bind-mount the Job API socket or pass BUILDKITE_AGENT_JOB_API_SOCKET and BUILDKITE_AGENT_JOB_API_TOKEN. The client cannot be built, the command exits 1 with empty stdout, and the print is never reached; `|| BK_TOKEN=""` then turns that into the generic "no token" line. That the fetch itself succeeds is confirmed by the cluster secret's last_read_at: 2026-09-02T10:16:33.496Z, the same second build 86851 logged the skip. Metadata reads do not update that field, and no other crcr-report job ran near that time. This is not an agent-version problem. secret get ships in the v3.73.1 agent our AWS queues run, and the behaviour is unchanged in the current v3.138.0, which merely explains itself better and names --skip-redaction as the remedy. Upgrading the agent or the Elastic CI Stack would not have fixed it. Passing --skip-redaction is safe on this path: the value is assigned to BK_TOKEN and used only as a curl Authorization header, it is never echoed, and the script does not run under set -x. The flag must precede the key, because urfave/cli v1 stops parsing flags at the first positional argument. The alternative, bind-mounting the Job API socket into every containerized step, is a ci-infra change with a far wider blast radius for no benefit here. The stderr diagnostics are kept. Previously 2>/dev/null collapsed a missing secret, a denied policy, an unsupported subcommand, an empty value and this Job API failure into one indistinguishable line, which is why this took several build cycles to find. Only stderr is echoed; stdout is the secret and must not be logged. Behaviour is otherwise unchanged: still best-effort, still exit 0 on every failure path, still prefers BUILDKITE_API_TOKEN from the environment. Test Plan: ``` bash -n .buildkite/scripts/crcr-report.sh shellcheck -S warning .buildkite/scripts/crcr-report.sh ``` Confirmed --skip-redaction exists in the agent version the queues actually run, rather than assuming it: ``` curl -s https://proxy.golang.org/github.com/buildkite/agent/v3/@v/v3.73.1.zip -o v3.73.1.zip unzip -q v3.73.1.zip grep -n 'skip-redaction' 'github.com/buildkite/agent/v3@v3.73.1/clicommand/secret_get.go' ``` Diagnostics paths exercised against a stub buildkite-agent: exit 1 with an error message reports the agent's own message and version, exit 0 with empty stdout reports "resolved but is empty", and exit 0 with a token proceeds past the token check. In the success case the log was grepped for the stub token value: 0 matches, so the secret is not echoed. Test Result: not confirmed end to end yet. The fix needs the next torch-nightly (or a manual build with TORCH_NIGHTLY=1) to prove the report actually posts. The signal is that the "no Buildkite API token" line disappears and crcr_report.py runs. Authored with the assistance of an AI coding assistant. Signed-off-by: Andrey Talman <atalman@fb.com>

--skip-redaction disables Buildkite log redaction for this lookup, so line 44 must state that exception. BK_TOKEN is used by the shell curl Authorization header; .buildkite/scripts/crcr_report.py receives OIDC_TOKEN, not BK_TOKEN. Do not claim that BK_TOKEN cannot reach logs unless callers also prevent shell tracing, which exposes command-substitution assignments and expanded arguments.

v3.73.1's secret_get.go creates the Job API client unconditionally and only checks SkipRedaction afterwards, so under the docker plugin -- no Job API socket in the container -- it returns 'failed to create Job API client' before the flag is ever read. The ordering was only corrected in v3.107.0; every tag from v3.74.0 through v3.106.0 has the same problem. Skipping redaction would also have stopped the token being registered with the log redactor, losing that protection for no gain on this agent. Keep the diagnostics: surfacing stderr and the agent version is what makes the 'failed to create Job API client' message visible, which names the root cause instead of collapsing every failure into one 'no token' line.

Problem
The CRCR nightly report never posts.
crcr-report.shswallowed stderr when reading the API token:so a missing secret, a denied access policy, an agent that is not on PATH, and an agent that cannot reach the Job API all collapse into the same
no Buildkite API tokenline. We spent a day eliminating the secret's existence, its key name, the cluster, the agent binary, the agent version and the access policy without ever seeing the actual error.Change
Report why the lookup failed:
buildkite-agent --versionin the failure linestdout is still captured into
BK_TOKENand never echoed, so the token cannot reach the log.Why not
--skip-redactionAn earlier revision of this PR passed
--skip-redaction, on the theory that the docker plugin does not expose the Job API socket to the container and the agent therefore refuses to print a value it cannot register with the log redactor.That is the right diagnosis but the wrong fix, and it cannot work on the deployed agent. In v3.73.1 the Job API client is created unconditionally, before
SkipRedactionis consulted:With no socket it returns before the flag is read, so the flag is inert. The ordering was only corrected in v3.107.0, which moves
NewDefaultClientinside the!SkipRedactionbranch. Checking the intermediate tags, every release from v3.74.0 through v3.106.0 behaves like v3.73.1 -- the change lands exactly at v3.107.0.Skipping redaction would also have stopped the token being registered with the log redactor, losing that protection for no benefit on this agent.
Credit to @khluu and their agent for catching this; the flag would have shipped and changed nothing.
What this run should show
If the socket theory is right, the log should now read:
which names the root cause outright.
Actual fix
Once confirmed, the real options are to expose the Job API socket to the container in the docker plugin config, or to pass the token through the step's
environment:instead of fetching it in-container. Upgrading the fleet to >= v3.107.0 would also make--skip-redactionviable, but that is a large change for one report script.This PR is the diagnostic step only.
