SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill captures failure data and logs it to a persistent registry for formal analysis of root causes and preventive rules.

Core Features & Use Cases

Centralized logging: appends structured postmortem entries to a central registry (POSTMORTEMS.md) for auditability and learning.
Trigger & inputs: supports common failure signals (log failure, postmortem, why did this fail, record error) with clear input parameters.
Integrated workflow: provides a guided analysis path to document root cause and preventive actions, enabling reliable incident learning.

Quick Start

Run the PowerShell script to log a failure example: execute the script with -Command "deploy" -Error "Out of memory" -Context "Deployment" to create a new postmortem entry.
