Superpowers (Hardened)

A security-hardened fork of obra/superpowers — a complete software development workflow for AI coding agents built on composable skills.

What's Different

This fork applies the following security changes on top of upstream:

• Removed authority-escalation markup patterns from injected context
• Added stricter hook and path validation
• Added scope and data-handling constraints for subagent review prompts
• Excluded brainstorming browser server components and other non-essential attack surface

For details on how Superpowers works (workflow, philosophy, skills library, contributing), see the upstream README.

Installation
