Practical overview
When it fits
Use it when an A2A task needs a routing decision after execution has begun and the decision should account for progress, remaining work, capability and constraints.
Who it is for
- Developers building A2A agent orchestration systems
- Researchers studying task routing and checkpoint-aware reconfiguration in multi-agent systems
Documented uses
- Choose whether an in-flight task should stay with its incumbent agent, add collaborators or transfer to a peer.
- Account for completed requirements and artifact portability when evaluating a change of agent ownership.
- Compare candidate assignments and schedules against permissions, budget and deadline constraints.
- Record execution outcomes and export the router's learned state.
Requirements & limits
The repository is public and open source under the MIT license. The README specifies Python 3.10 or later and no runtime dependencies, and labels the project a research preview.
- The three modes preserve different ownership arrangements: SELF retains the incumbent, COLLABORATE keeps incumbent ownership, and HANDOFF transfers full ownership.
- The router considers completed work, artifact portability and observed partial quality when estimating what remains after rerouting.
- The README describes permission-first eligibility filtering and budget- and deadline-constrained route evaluation.
- The reference implementation is documented as having no runtime dependencies beyond Python 3.10 or later.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
