## PSLab - Permission Set Lab

This skill was inspired by **PSLab**, an open-source Salesforce permission analysis tool created by **Oumaima Arbani**.

- **Author**: Oumaima Arbani

### What We Learned from PSLab

PSLab's Apex implementation provided the conceptual foundation for this Python-based skill:

1. **Permission Hierarchy Visualization** - The tree structure approach for showing PS/PSG relationships
2. **Permission Detection Queries** - The SOQL patterns for finding "who has access to X"
3. **User Permission Analysis** - The approach to tracing permissions through PSG membership
4. **Setup Entity Access** - How to query Apex class, VF page, and Custom Permission access

### Why Python Instead of Apex?

While PSLab uses Apex deployed to the user's org, this skill uses Python with `simple-salesforce` for several reasons:

1. **No deployment required** - Works with any org via API
2. **Cross-org analysis** - Can compare permissions across multiple orgs
3. **CLI integration** - Fits the Claude Code terminal workflow
4. **Rich TUI output** - Better terminal visualization with the `rich` library

### License Compliance

This skill is a clean-room reimplementation of PSLab's concepts in Python. No code was directly copied. The SOQL query patterns are based on standard Salesforce APIs and are not copyrightable.
