Based on SOC occupation classification
A QA gate that validates potentially destructive or irreversible actions before execution.
Detect and prevent state-visibility violations across execution contexts within a single transaction.
Convert mixed terminal output and instructions into safe, paste-ready command blocks.
Prepares isolated sub-workspaces for parallel agent execution. Copies context and generates specific mission instructions for "Worker" agents.
Detects when the agent is stuck in a reasoning loop or unproductive state by analyzing tool usage and sentiment patterns.
Generates a 'Red Team' critique of recent code or plans to identify weak assumptions and edge cases.

Systematically captures failure data. When a tool fails or a plan is abandoned, this skill logs the event to a persistent registry (POSTMORTEMS.md), forcing an synchronous analysis of why it happened (Root Cause) and how to prevent it (Preventive Rule).

**Context:** Deployment
**Command:** `npm build`
**Error:** `Heap out of memory`
### 🕵️ Analysis
1. **Root Cause:** Node processes default to 512MB RAM.
2. **Preventive Rule:** Always set NODE_OPTIONS="--max-old-space-size=4096" for builds.
