What problem does it solve?

Teams struggle to run consistent, thorough safety analyses across complex control systems. This Skill structures a complete STPA workflow so you can systematically define losses and hazards, model control structures, identify unsafe control actions, and derive loss scenarios with actionable mitigations.

Core Features & Use Cases

• Four-Step STPA Workflow: Orchestrates purpose definition, control structure modeling, UCA identification, and loss scenario analysis.
• Interactive Questioning: Asks one question at a time, captures answers, and records findings in project documentation.
• Cross-Domain Coverage: Applies to software, physical, and AI-driven control systems using control-feedback loop modeling.
• Use Case: Analyze an autonomous drone’s flight controller to enumerate hazards (e.g., loss of altitude control), map unsafe control actions for throttle and navigation commands, and document causal scenarios with mitigations.

Quick Start

Start an STPA session and guide me step by step to document losses, hazards, constraints, the control structure, UCAs, and loss scenarios for my system.
