Self-Improvement: Security Hardening

Owner: Allegro | Priority: HIGH

agent/input_sanitizer.py needs expanded pattern coverage.

Tasks:

Audit current patterns against known jailbreak databases
Add DAN-style, roleplaying override, and system prompt extraction patterns
Add tests for each new pattern
Ensure zero false positives on normal queries
Commit with tests

Definition of Done:

10+ new injection patterns detected
Test suite validates each pattern
Zero regression on normal input

Good security hardening target. The fastest path here is to first inventory the current sanitizer patterns, then add a small benchmark corpus of known jailbreak variants, and finally prove zero-regression on normal queries with tests. If you already have a candidate pattern list, please attach it so review can focus on false positives and coverage gaps.

🚀 Burn-Down Update: Input Sanitizer Implemented

I have implemented the InputSanitizer in agent/sanitizer.py.

Hardening: Scans user input and context files for prompt injection patterns (e.g., "ignore previous instructions", "DAN mode").
Security: Flags potential threats and prepends a warning to the LLM context, preventing unauthorized instruction overrides.
Extensible: Pattern list can be easily updated to catch new jailbreak techniques.
