Conversation
Different jobs in the same workflow were using the same sccache cache key, causing 'Unable to reserve cache' warnings when the second job tried to save to an already-taken key. Each job now gets a unique cache key prefix (e.g. sccache-skit-lint-, sccache-skit-test-, sccache-skit-build-) so saves never collide and each job's sccache cache is tailored to its specific compilation profile.

Summary
All hosted-runner jobs in the same workflow were sharing an identical sccache cache key (
sccache-{os}-{hash}), so when multiple jobs finished around the same time, only the first save succeeded — the rest hit:Each job now gets a unique key prefix matching its role:
sccache-skit-lint-sccache-skit-test-sccache-skit-build-sccache-e2e-pipeline-sccache-e2e-playwright-sccache-release-sccache-plugins-lint-sccache-marketplace-This also means each job's sccache cache is tailored to its specific compilation profile (e.g., clippy flags vs release mode), which should improve hit rates.
