It is especially valuable in agentic pipelines where agents may crash and you cannot afford a permanently blocked workflow — the automatic lease expiry on locks makes it safer than home-rolled locking. Prefer this over ad-hoc polling patterns or external Redis/database locks when you want a lightweight, pay-per-use coordination primitive with webhook delivery.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-29T07:01:27.147Z","isFirstParty":false,"canonicalSlug":"datasieve-coordination-workspace-986b6f76"}
