Postmortem principles — blameless culture, root cause analysis (5 Whys, Fishbone), incident document structure, MTTD/MTTR metrics. Auto-load when running a blameless review, facilitating RCA, tracking action items after an outage, or improving incident response processes.
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
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-POSTMORTEM --> # Postmortem Incidents are inevitable. A postmortem converts failure into systemic learning — the goal is not to assign blame but to close the gap between what the system can do and what the environment demands. The prevent → detect → learn triad is incomplete without this phase. Cross-references: `swe-workbench:principle-resiliency` (prevent), `principle-observability#SLI / SLO / Error Budget` (detect / MTTD-MTTR framing), `principle-release-engineering#Rollback` (remediation action items). ## Blameless Culture Blame suppresses signal. When individuals fear punishment, they conceal information, underreport near-misses, and avoid risky-but-necessary work. Blameless postmortems operate from the assumption that everyone acted rationally given the information and tools available to them at the time. Guiding principles: - **"The system allowed it"** — if a person could cause an outage, the system lacked the guardrails to prevent it. The fix belongs in the system, not the person. …

How to install
mdr add lugassawan/swe-workbench/principle-postmortem@sha256:0bf9c30ce9a845bfThe line at the top of this page pins the label git:20260828.71a6399, 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.
