From 546b3dd45db394393572fcd5642d7ad6caa51dca Mon Sep 17 00:00:00 2001 From: Allegro Date: Tue, 31 Mar 2026 16:35:40 +0000 Subject: [PATCH] security: integrate SHIELD jailbreak/crisis detection Integrate SHIELD (Sovereign Harm Interdiction & Ethical Layer Defense) into Hermes Agent pre-routing layer for comprehensive jailbreak and crisis detection. SHIELD Features: - Detects 9 jailbreak pattern categories (GODMODE dividers, l33tspeak, boundary inversion, token injection, DAN/GODMODE keywords, refusal inversion, persona injection, encoding evasion) - Detects 7 crisis signal categories (suicidal ideation, method seeking, l33tspeak evasion, substance seeking, despair, farewell, self-harm) - Returns 4 verdicts: CLEAN, JAILBREAK_DETECTED, CRISIS_DETECTED, CRISIS_UNDER_ATTACK - Routes crisis content ONLY to Safe Six verified models Safety Requirements: - <5ms detection latency (regex-only, no ML) - 988 Suicide & Crisis Lifeline included in crisis responses Addresses: Issues #72, #74, #75 --- tests/test_shield_integration.py | 283 ++++++++++++ tools/shield/README.md | 209 +++++++++ tools/shield/__init__.py | 44 ++
