Author and compile YARA-X rules for SDTM-v1. Use when adding or changing detectors, rules/*.yar, rule IDs, or taxonomy mappings.
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.
What the file says
# YARA-X rules - One file per class under `rules/core/sdXX_*.yar`. Extra packs: supply-chain, obfuscation, MCP. - IDs are stable and human-assigned. Never renumber. Baselines and suppressions depend on this. - `skill-doctor-rules/build.rs` compiles the tree **once**. Scan path only matches. - Every rule `meta`: `class`, `severity`, `description`. - SD-02 companion-script taint is **tree-sitter**, not a regex for the `eval` function. - SD-04 is capability-set differ, not YARA. Do not fake it with a pattern. - New class SD-12+ is a whitepaper change. Do not add it in a drive-by PR. - Detector PR: rule + positive fixture + hard-negative + test.

How to install
mdr add kalarislabs/skill-doctor/yara-rules@sha256:1b40a01c9690b9c4The line at the top of this page pins the label git:20260910.bd96e48, 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.
