Investigate system crashes, OOM kills, and unresponsive episodes. Analyzes previous boot logs, identifies memory hogs, tallies per-process-group consumption, checks agent and workspace state, and produces a recovery summary. Use after a hard reset, freeze, or reboot caused by resource exhaustion.
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
# Crash Investigation Post-crash forensic analysis for developer workstations running AI agents, containers, and k8s workloads. ## When to Use - System was unresponsive and required a hard reset - OOM killer was active (processes were killed unexpectedly) - CPU was pegged at 100% for an extended period - System rebooted unexpectedly - Agents were running overnight and the machine froze ## Investigation Workflow Work through each phase in order. Collect all evidence before drawing conclusions. --- ### Phase 1: Establish Timeline Determine when the crash happened and how long the previous session ran. ```bash # List recent boots — the previous boot (-1) is the crashed session journalctl --list-boots | tail -5 # Check reboot history last -x reboot shutdown | head -10 ``` Record: - **Previous boot start**: when the session began - **Previous boot end**: when the crash/reset occurred - **Duration**: how long it ran before crashing --- ### Phase 2: Check for OOM Kills OOM (Out of Memory) kills are the most common cause of system freezes on dev machines. ```bash # All OOM events from the crashed boot …

How to install
mdr add eltmon/overdeck/crash-investigation@sha256:478259b99bb02041The line at the top of this page pins the label git:20260618.e501626, 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.
