Task State Ledger
Data storeOrchestrationOrchestration & Toolsarc:TaskStateLedger
A shared record of task ownership, status and explicit completion flags across agents in a multi-agent workflow.
Responsibility. Tracks which agent owns and has completed which task.
Also known as: Workflow state, Task status tracker, Running bibliography / processed-items tracker

- Worker Agent abstract Ch1.3 Ch2.4
Design guidance
- MUST record explicit task completion flags so multiple agents do not start the same expensive computation.
- SHOULD record task ownership to prevent both overlap and coordination gaps.
Quantitative guidance
As stated by the sources; verify before use.
- Redundant and circular work affects roughly 50% of failed collaborative deployments (Ch1.3).
Classification
- Quality attributes
- Reliability (ISO/IEC 25010 | NIST AI RMF: valid and reliable)Transparency and accountability (NIST AI RMF: accountable and transparent)
- Risks mitigated
