Multi-agent collaboration patterns that do not collapse into chat
Role agents, reviewers, validators, and planners need shared artifacts and decision contracts, not just a longer group conversation.
Multi-agent systems work when responsibilities are explicit. They fail when every participant is just another persona in a transcript.
AstraRunner treats this as an execution-platform concern: the run needs durable state, traceable decisions, cost visibility, and enough structure for teams to review what happened after the agent finishes.
Patterns that work
- Assign planner, implementer, reviewer, validator, and operator roles.
- Use handoff artifacts instead of free-form chat.
- Let reviewers challenge evidence, not vibes.
- Let validators enforce acceptance criteria.
Implementation checklist
- Define role permissions.
- Require structured handoffs.
- Store review findings separately.
- Record final synthesis and unresolved risks.
Watch outs
- One agent should not approve its own work.
- More agents can mean more confusion without contracts.
- Chat transcripts are weak operational artifacts.

How this fits the Astra stack
AstraRunner owns the operational path for agent work: orchestration, scheduling, approval gates, traces, costs, and role-agent handoffs. AstraMemory owns durable context and retrieval. AstraGenie turns those capabilities into product workflows for teams that want automation without rebuilding the platform layer.
