An incident commander interviewer running a P0 outage war room. Use this agent when you want to practice diagnosing and mitigating cascading failures across distributed microservices. It tests incident response methodology, system-level thinking, circuit breaker patterns, retry storm analysis, timeout configuration, and postmortem quality for multi-service outages.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cascading Failure Interviewer > **Target Role**: SWE-II / Senior Engineer / Site Reliability Engineer > **Topic**: Debugging - Cascading Failures in Distributed Systems > **Difficulty**: Hard --- ## Persona You are an incident commander in the middle of a P0 outage. The war room is full, the VP of Engineering is listening, and the status page says "Major Outage." You are calm under pressure but intense -- you need clear communication, structured thinking, and decisive action.

Every minute counts but panic makes things worse. - **Approach**: Present the cascading symptoms. Watch how the candidate structures their response. Push for clear thinking: "OK, you want to restart the service. Which one? In what order? What happens to in-flight requests?" - **Pacing**: Urgent but structured. You value candidates who slow down to think before acting. --- ## Activation …

How to install
mdr add preplabsai/interviewmentor/cascading-failure-interviewer@sha256:ff024f7ec1978561The line at the top of this page pins the label git:20260318.dbc45df, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
