SKILL: Self-Edit Agent
Overview
The Self-Edit Agent enables the agent to modify its own code and files with safety guarantees. It handles:
- Syntax errors - auto-balance parens, then LLM fix
- File modifications - surgical edits with memory rollback on failure
- Skill hot-reload - swap compiled skills without breaking the system
