scar-safety

A safety system that grows stronger with every incident. Combines static threat detection (regex/heuristic) with a scar-based reflex arc that learns from real security incidents.

How it works

1. Static detection -- Built-in regex patterns catch common threats: secret exposure, dangerous commands, injection patterns, data exfiltration, privilege escalation.
2. Scar memory -- When a real incident occurs, it is recorded as an immutable scar in safety_scars.jsonl.
3. Reflex arc -- Before any action, pattern-match against all scars. Blocks repeat threats instantly with zero LLM calls.
4. Severity levels -- CRITICAL (auto-block), HIGH (warn+confirm), MEDIUM (warn), LOW (log).

Unlike static rule lists, scar-safety adapts: every recorded incident makes the system smarter.

Usage

# Check if an action is safe
