semgrep-rule-creator skillA

semgrep-rule-creator is agent-read markdown (skill) from dannykkh/skill-olympus: Creates custom Semgrep rules for detecting security vulnerabilities, bug patterns, and code patterns. Use when writing Semgrep rules or building custom static analysis detections..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dannykkh/skill-olympus/semgrep-rule-creator@git:20260901.8bc747e
Exact content
mdr add dannykkh/skill-olympus/semgrep-rule-creator@sha256:6879173cb00f368d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
