Why logs are not enough for agent systems
Agent systems need structured traces, artifacts, and decisions because plain logs cannot explain autonomous behavior.
A log line records an event. An agent trace records the chain of reasoning inputs, tool effects, and policy gates that led to an outcome.
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
- Use spans for model, tool, review, approval, and retry events.
- Attach prompts, redacted inputs, and output summaries.
- Store decision records beside trace spans.
- Correlate traces with cost and grade data.
Implementation checklist
- Choose trace identifiers that survive async work.
- Redact secrets before storage.
- Link logs to run IDs.
- Keep artifacts discoverable from the trace.
Watch outs
- Verbose logs can still miss the decision.
- Prompt data may contain sensitive context.
- Uncorrelated logs make cross-agent debugging slow.

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.
