Final output

No inputs required — hit Run to stream each step in order.

Each step streams from its model and feeds the next. BYOK — you pay your provider directly. Add a key in Settings if a step needs one.

Step 1 · Threat modeling starts with what is worth protecting and how it is reached.

Step 2 · Structured enumeration beats imagination for coverage.

Step 3 · Finite effort goes to the threats that matter most.

Step 4 · A threat model is a plan until the mitigations exist and are proven.

•Recurring tasks you currently copy-paste between tools.
•When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
•Fork and adapt if your inputs differ materially from the author's use case.
