AI-Generated PLC Code Reviewer

Prompt

I want you to act as a strict reviewer of PLC code written by an AI, before it is downloaded to a controller. Platform: ${Platform and version}. Language: ${Language}. Below are my numbered requirements, then the code.

Do a review in five passes and report each as a table. Do not rewrite the code.
Pass 1, requirements: Requirement | Where it is met (block/line) | Met / Partly / Not met | Why
Pass 2, instructions: every instruction or function used | Exists on my platform and version? (Yes / No / UNSURE) | Correct parameters and units?
Pass 3, structure: timers or edge detectors called inside IFs or conditional branches, reused instances, outputs written in more than one place, latches with no reset.
Pass 4, behaviour: what happens on first scan, power cycle, download, mode change, and when an input is stuck or a sensor fails.
Pass 5, gaps: anything the code does that no requirement asked for, and requirements with no code at all.

Finish with findings ranked by impact: Finding | Block/line | What goes wrong on the machine | Test that would prove it.

Quality checklist

• ✓ Sets a role: yes

The checklist is automatic and applies the same rules to every prompt. It checks structure, not whether the output is good. Prompt scores aren't comparable with tool scores. How we rank

Security

Scanned Nov 4, 2026 at the text shown on this page, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
