Custom Rules - Krixai

Define your own detection rules using keywords, regex patterns, or semantic similarity.

Configuration

Custom rules are configured in your Krixai dashboard or via the API.

{
  "custom_rules": [
    {
      "name": "internal_project_names",
      "type": "keyword_list",
      "action": "redact",
      "keywords": ["Project Phoenix", "Codename Atlas", "Q4 Launch"]
    },
    {
      "name": "competitor_mentions",
      "type": "regex",
      "action": "flag",
      "pattern": "(lakera|rebuff|prompt\\s*guard)"
    }
  ]
}

Rule Types

keyword_list: Exact string matching against a list of terms. Very fast.
regex: Regular expression matching for complex patterns.
semantic: Vector similarity matching to catch paraphrased concepts (requires Enterprise plan).
