Overview
Agent skill to reverse engineer a SaaS product through the browser into a knowledge base for rebuilding it: screens, rules, data model, design tokens and production barriers, without touching production data.
The project is written in JavaScript and has 29 forks. It was created 6d ago.
What it is
RES is an agent skill for reverse engineering a SaaS product through the browser and turning what it finds into a knowledge base detailed enough to rebuild and launch a competing product — without touching production data. The output covers screens, rules, data model, design tokens and production barriers.
Capabilities explicitly described
- Studying a web product through the browser and documenting how it works. - Handing off everything needed to rebuild and launch it, as the README preview puts it. - Capturing rules in a testable form: the preview shows Gherkin-style statements (a deal with exactly one open activity, then a "Schedule next activity" dialog opens, and cancelling shows a warning icon) each tied to evidence references such as `EV-031` and `EV-032`, with a category like "permissioned integration".
The topic tags identify it as an agent skill for `claude-code` with `browser-automation`, `knowledge-base` and `reverse-engineering`. It is written in JavaScript and licensed MIT.
Getting started
The supplied evidence gives no installation or invocation instructions for the skill. Read the repository README to see how the skill is loaded into an agent and how the evidence-tagged knowledge base is produced and stored.

# see README for setupFrequently Asked Questions
What does RES produce?
A knowledge base describing a SaaS product — screens, rules, data model, design tokens and production barriers — intended for rebuilding it.
Does it touch production data?
The description says it works without touching production data, studying the product through the browser instead.
How are findings recorded?
The README preview shows Gherkin-style rules with evidence references such as `EV-031` and `EV-032` and a category label, so each finding is traceable.
Which agents can use it?
It is tagged as an agent skill for `claude-code` with browser automation; see the README for loading instructions.
