#+TITLE: SKILL: Self-Fix Agent (Universal Literate Note)
#+ID: skill-self-fix
#+STARTUP: content
#+FILETAGS: :self-repair:autonomy:debugging:psf:
#+DEPENDS_ON: skill-scientist skill-shell-actuator

* Overview
The **Self-Fix Agent** is the system's "Repair Mechanism." It takes the failure hypotheses from the **Scientist Agent**, applies surgical code modifications in a sandboxed environment, and merges the fix only after rigorous verification by the **TDD Runner**.

* Phase A: Demand (PRD)
:PROPERTIES:
:STATUS: FROZEN
:END:

** 1. Purpose
Enable autonomous, verified code correction without human intervention.

** 2. User Needs
- **Surgical Modification:** Apply targeted changes to specific Lisp functions or Org headlines.
- **Sandboxed Verification:** Test every fix in a controlled environment before merging.
- **Rollback Capability:** Use the **Interactive Steering** snapshots to revert if a fix fails.
- **Audit Logging:** Every fix must be documented in `RCA.org`.

* Phase D: Build (Implementation)
