Standalone skill for multi-perspective PLC code security and quality analysis. Triggers on: "review", "audit", "analyze", "security check", "vulnerability scan", "code review", "check this code", "is this safe", "find issues" when combined with PLC, SCL, ST, LAD, FBD, Structured Text, or block context. Also triggers when the user pastes PLC code and asks for feedback, or uploads exported SimaticML XML files. This skill is independent of tia-openness-roadmap — it does not perform engineering…
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
# plc-code-analysis ## Goal Perform structured, multi-perspective security and quality analysis of PLC code, producing a severity-ranked findings report. Acts as an automated "second pair of eyes" for automation engineers. ## Independence from tia-openness-roadmap This skill is NOT routed by `tia-openness-roadmap`. It has its own trigger patterns and operates independently. The Openness roadmap handles engineering automation (create, modify, import/export via API). This skill handles analysis and review of existing code. The skill consumes code exported through Openness/VCI or pasted by the user, but it does not depend on a particular wrapper. ## Input recognition PLC code commonly arrives in one of three ways. Identify the exact format and provenance before analysis. ### Format 1 — Raw SCL / Structured Text The user pastes or uploads `.scl`, `.st`, or plain-text PLC code. This is the simplest case. Parse directly as text. Look for FUNCTION_BLOCK, FUNCTION, ORGANIZATION_BLOCK, DATA_BLOCK headers to identify block boundaries. ### Format 2 — SIMATIC SD source documents (V21) TIA Portal V21 can export S7-1200/S7-1500 SCL, LAD, FBD, DB, F-DB, UDT, and …

How to install
mdr add czarnak/totally-integrated-claude/plc-code-analysis@sha256:4f4c9fe39aea176aThe line at the top of this page pins the label git:20261003.5127062, 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.
