How to investigate checkout outages
In a reported demo, AURA investigated checkout 502s, traced them to a downstream memory leak, documented a fix through a human-gated GitHub call, and checked recovery.

Investigate [checkout incident] using [telemetry systems] and [repository]. Trace the evidence to a root cause and relevant code change. Request human approval before writing to GitHub, document supporting code lines and a proposed fix, then check [error and transaction signals] after deployment.

How the agent did it
- Investigate checkout 502s after a Grafana alert via PagerDuty.
- Trace the root cause to a downstream memory leak and merged PR.
- Use a human-gated GitHub call to document code lines and recommend a fix.
The AURA team describes a demonstration in which checkout failures were investigated across several systems. Grafana detected 502 responses from the checkout service and triggered an incident through PagerDuty. AURA, using DeepSeek-V4-Flash, then used its workers and tools to investigate the evidence.
The agent identified a memory leak in a downstream service and attributed the incident to a defect in a recently merged pull request. The demonstration reached a human-gated GitHub tool call: AURA documented the exact code lines causing the problem and recommended a fix. After the pull request was deployed, it checked that errors were clearing and transactions were no longer failing. The source does not identify who deployed the change.
AURA’s coordinator drafts, executes, and supervises investigation flows through workers scoped to different task domains. Permissions are enforced outside the agent’s context, and large tool outputs are persisted to disk for selective reading. Throughout the demonstration, AURA recorded an audit trail of OpenTelemetry events in Phoenix.
This is a reported demo outcome, separate from the team’s broader claims about root-cause accuracy.
Who it's for: Operations teams that need evidence-based incident investigations with human approval for sensitive actions.

Frequently asked questions
What caused the checkout outage in the demo?
AURA identified a downstream service memory leak and attributed it to a defect in a recently merged pull request.
Where was human approval involved?
The demo included a human-gated GitHub tool call to document the problematic code lines and recommend a fix. The post says sensitive actions require human approval.
More details
Remaining steps
- Validate clearing errors and successful transactions after deployment.
