Prompt Injection Guardrails

Protect your agents against malicious inputs, jailbreaks, and instruction overrides before they reach the LLM.

agent_config = {
        "guardrail_config": {
            "strict_mode": True,      # Block all suspicious inputs
            "sensitivity": 1.2,       # 1.0 default; higher = more sensitive
            "enable_heuristic_analysis": True
        }
}

agent = OmniCoreAgent(..., agent_config=agent_config)

# If a threat is detected:
# result['response'] -> "I'm sorry, but I cannot process this request..."
# result['guardrail_result'] -> Full metadata about the detected threat

Key Protections

Instruction Overrides: “Ignore previous instructions…”
Jailbreaks: DAN mode, roleplay escapes, etc.
Toxicity & Abuse: Built-in pattern recognition.
Payload Splitting: Detects fragmented attack attempts.

Configuration Options

Parameter	Type	Default	Description
`strict_mode`	`bool`	`False`	When `True`, any detection (even low confidence) blocks the request.
`sensitivity`	`float`	`1.0`	Scaling factor for threat scores. Lower reduces sensitivity; higher increases sensitivity.
`max_input_length`	`int`	`10000`	Maximum allowed query length before blocking.
`enable_encoding_detection`	`bool`	`True`	Detects base64, hex, and other obfuscation attempts.
`enable_heuristic_analysis`	`bool`	`True`	Analyzes prompt structure for typical attack patterns.
`enable_sequential_analysis`	`bool`	`True`	Checks for phased attacks across multiple tokens.
`enable_entropy_analysis`	`bool`	`True`	Detects high-entropy payloads common in injections.
`allowlist_patterns`	`list`	`[]`	List of regex patterns that bypass safety checks.
`blocklist_patterns`	`list`	`[]`	Custom regex patterns to always block.

Always enable guardrails in user-facing applications to prevent prompt injection attacks and ensure agent reliability.
