What this skill does

IRQL -- Incident Response Query Language Compose IRQL function pipelines from selector, extractor, and enricher building blocks. IRQL wraps raw KQL security tables behind intent-revealing, composable functions so analysts (and LLMs) can express hunts without memorizing schemas, cluster locations, or join keys. Activation Triggers Use this skill when the user: Explicitly mentions IRQL, Get, Extract, or Enrich functions Says "use IRQL" or "write an IRQL query" Requests a composable hunting pipeline using known IRQL selectors Do not activate for generic security queries (e.g. "find failed logins") unless the user explicitly asks for IRQL. Route those to azure-kusto instead. Not a natural-language-to-IRQL converter. This skill composes IRQL function pipelines and may handle basic natural-language requests that map directly to known selectors and simple filters. For general NL-to-KQL or NL-to-IRQL conversion, use a dedicated query-generation skill (available separately). IRQL Function Preflight Before generating a pipeline, verify IRQL is available on the target database: If no IRQL functions are found, inform the user that IRQL is not deployed on the target database and suggest using azure-kusto for raw KQL queries instead. IRQL functions are a prerequisite -- this skill does not deploy base IRQL selectors. What IRQL Is IRQL is a function-based dialect on top of KQL. It provides: 1. Unified schema -- disparate security tables project into consistent column names regardless of the underlying data source 2. Composability -- small functions chain via invoke to build complex hunts from simple steps 3. Portability -- the same IRQL pipeline works across different clusters/databases; only the Get primitives need re-pointing IRQL is not a separate language. It's KQL functions you invoke. Any valid KQL works alongside IRQL functions. Deploying IRQL IRQL functions are stored KQL functions (.create-or-alter function). …
