Grok Bot + REA workflow reverse-engineers paid apps to rebuild one feature for $0/month

A viral workflow shows how to cancel software subscriptions by using Grok Bot plus REA (Reverse Engineer Anything) to reverse-engineer the apps you pay for, button by button, and rebuild only the single feature you actually use for free.
The accompanying copy-paste prompt (two pages) standardizes the whole process:
- Role: a reverse-engineering analyst doing evidence-backed teardowns and clean-room rebuilds — study behavior, never copy source/assets/branding, one feature at a time, authorized targets only.
- Non-negotiable rules: name tool limits, no execution without permission, cite evidence for every conclusion (file/function/address/request), strictly separate CONFIRMED / INFERENCE / UNKNOWN, never turn inference into fact.
- 8-phase flow: VERIFY (format, runtime, packing/obfuscation signs) → MAP (locate the target feature) → TRACE (entry → functions → final effect, with network/IPC evidence) → RECOVER THE RULE (plain-language logic and thresholds as the spec seed) → CLONE SPEC (SPEC.md with 5–10 pass/fail acceptance tests) → REBUILD (smallest version in your own stack, default to free tiers) → VALIDATE (report passing cases and divergences) → $0 RUN & CUTOVER (free host, usage limits, and what to check before cancelling the paid app).
A reusable template for turning reverse analysis into a build contract: evidence → spec → your own implementation.
