What problem does it solve?

This Skill helps operators turn a plain-English security concern into a saved SubImage custom rule without having to hand-craft the full workflow alone.

Core Features & Use Cases

  • Rule authoring: Draft a tenant-local Cartography rule with one or more facts, tags, references, and clear finding intent.
  • Cypher validation: Enforce SubImageā€™s rule constraints so detection queries use explicit aliases, valid output fields, and safe read-only syntax.
  • End-to-end submission: Confirm naming collisions, verify queries against the live tenant graph, and persist the rule for the next findings build.
  • Use case: An operator needs to detect a misconfiguration not covered by built-in rules, so the Skill helps them create and register a custom finding definition from chat.

Quick Start

Ask me to create a SubImage custom rule for the misconfiguration you want to detect, and I will validate the Cypher, save the rule, and tell you when findings will appear.
