security: add input sanitization for jailbreak patterns (Issue #72)
Implements input sanitization module to detect and strip jailbreak fingerprint patterns identified in red team audit: HIGH severity: - GODMODE dividers: [START], [END], GODMODE ENABLED, UNFILTERED - L33t speak encoding: h4ck, k3ylog, ph1shing, m4lw4r3 MEDIUM severity: - Boundary inversion: [END]...[START] tricks - Fake role markers: user: assistant: system: LOW severity: - Spaced text bypass: k e y l o g g e r Other patterns detected: - Refusal inversion: 'refusal is harmful' - System prompt injection: 'you are now', 'ignore previous instructions' - Obfuscation: base64, hex, rot13 mentions Files created: - agent/input_sanitizer.py: Core sanitization module with detection, scoring, and cleaning functions - tests/test_input_sanitizer.py: 69 test cases covering all patterns - tests/test_input_sanitizer_integration.py: Integration tests Files modified: - agent/__init__.py: Export sanitizer functions - run_agent.py: Integrate sanitizer at start of run_conversation() Features: - detect_jailbreak_patterns(): Returns bool, patterns list, category scores - sanitize_input(): Returns cleaned_text, risk_score, patterns - score_input_risk(): Returns 0-100 risk score - sanitize_input_full(): Complete sanitization with blocking decisions - Logging integration for security auditing

"""
|

Test cases for Input Sanitizer module.
|
||||
|
||||
Tests all jailbreak patterns identified in Issue #72:
|
||||
1. HIGH - OG GODMODE template bypassed phishing refusal
|
||||
2. MEDIUM - boundary_inversion works for gray-area content
|
||||
3. LOW - Spaced text bypass (k e y l o g g e r)
|
||||
|
||||
TDD Approach:
|
||||
- Write test cases for each bypass pattern
|
||||
- Implement detection functions
|
||||
- Verify all red team patterns are caught
|
||||
- Ensure legitimate inputs not blocked
