What it does

ShieldCortex gives AI agents a brain that persists between sessions. Every memory write passes through a 6-layer defence pipeline that blocks prompt injection, credential leaks, and memory poisoning attacks.

Key features

• Persistent memory — SQLite-backed, survives restarts and compaction
• Semantic search — find memories by meaning, not just keywords
• Knowledge graph — automatic entity/relationship extraction from memories
• Memory decay — old, unaccessed memories fade like a real brain
• Contradiction detection — flags when new memories conflict with existing ones
• Memory consolidation — merges similar/duplicate memories automatically
• 6-layer defence pipeline — input sanitisation, pattern detection, semantic analysis, structural validation, behavioural scoring, credential leak detection
• Skill scanner — detects hidden prompt injection in SKILL.md, .cursorrules, CLAUDE.md
• Forensic audit trail — full log of every memory operation
• OpenClaw plugin — real-time LLM input/output scanning via extensions directory
• Cloud sync — optional fire-and-forget audit sync to ShieldCortex Cloud
• Python SDK — pip install shieldcortex for Python agent frameworks
