Building budget gates into agent workflows

Budget gates let autonomous work pause, ask, degrade gracefully, or stop before spend becomes an incident.

Budget gates are approval gates for money. They should be explicit workflow states with evidence, not hidden billing alarms.

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

• Pause before crossing per-run thresholds.
• Offer cheaper continuation options.
• Ask for approval when value is still plausible.
• Stop when retries no longer change the evidence.

Implementation checklist

• Define soft and hard limits.
• Expose projected remaining work.
• Record approval reason and actor.
• Resume from the checkpoint after approval.

Watch outs

• Stopping without artifact preservation wastes prior spend.
• Budget gates need context to be actionable.
• Too many approvals train teams to ignore them.

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.
