Author Cortex XSIAM Data Model Rules in Cortex Query Language (XQL). Turns a raw vendor log sample into a production-ready rule with a MAPPED-header comment block.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# cortex-platform-xdm-author

Author Cortex XSIAM data model rules in Cortex Query Language (XQL) from raw vendor log samples.

The current version is 2.15.0; the per-version change history lives in [CHANGELOG.md](CHANGELOG.md).

On top of base rule authoring, the skill auto-detects the source kind and applies the matching mapping set, each backed by a linter check. The table is the index; the detail lives in the reference, which is where to read before mapping that kind. Anything in the Hard rules or the Mapping decision checklist below applies whether or not you load a reference.

| Capability | Applies to | Lint codes | Reference |
| --- | --- | --- | --- |
| Record classification and catch-all | every rule -- `xdm.event.type` / `xdm.event.tags` decided per record; six markers are closed `EVENT_TAG` constants and virtualization is the bare string `"VIRTUALIZATION"`, unclassified records kept via the `GOCORTEX_UNMODELLED` sentinel so datamodel rows equal raw rows | WARN-045, WARN-046 | [record-classification.md](references/record-classification.md) |

How to install

The exact contents, by fingerprint
mdr add gocortexio/skills/cortex-platform-xdm-author@sha256:16a9556352928794

The line at the top of this page pins the label v2.15.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
