TIA CICD DIFF

Use Siemens TIA Portal Openness API to diff two .zap18 projects and return structured code & hardware changes.

Security Scan

The skill's claims, required capabilities, and instructions are internally consistent for a TIA Portal Openness-based diff tool; it is instruction-only and simply directs the agent to run local Openness scripts and parse their JSON output.

Purpose & Capability

The name/description (diff two .zap18 projects using Siemens Openness) matches the instructions and file README: the workflow requires Siemens TIA Portal Openness, external PowerShell/batch scripts that call SiemensEngineering.dll, and filesystem access to read archives and write diff JSON. There are no unrelated credentials, binaries, or installs requested.

Instruction Scope

SKILL.md explicitly allows calling external scripts and reading/writing the working directory, which is necessary for extracting and comparing .zap18 (ZIP) contents. The instructions are minimal and assume the presence of an external script (e.g. tia_diff.bat / TIA-Openness-Diff.ps1) but do not include or pin that script in the bundle — the agent will run whatever script is present. This is expected for this kind of skill but worth noting: you should verify the actual script before execution.

Install Mechanism

No install spec is present (instruction-only). That is the lowest-risk install model. The skill relies on existing Siemens TIA Portal and Openness being installed on the host; it does not attempt to download or install code itself.

Credentials

No environment variables, credentials, or config paths are requested. The README lists only requirements that are relevant (TIA Portal V18, PowerShell). There are no disproportionate or unrelated secret accesses.

Persistence & Privilege

The skill does not request permanent presence (always: false) and does not modify other skills or system-wide settings. It instructs local script execution and file I/O only, which is appropriate for a project diff utility.

Assessment

This skill is coherent for its stated purpose, but it is instruction-only and depends on external scripts you (or your environment) must provide. Before using it: 1) Confirm you have Siemens TIA Portal V18 + Openness installed. 2) Locate and inspect the actual diff script (TIA-Openness-Diff.ps1 or tia_diff.bat) that the agent will run — do not run untrusted scripts. 3) Run the script in a controlled environment or on copies of projects (it extracts archives and writes temp/output files). 4) Verify the script does not perform unexpected network calls or handle credentials. 5) Ensure appropriate file permissions and backups for projects. If you cannot inspect or trust the external script, do not grant the agent permission to execute it automatically.

You can:

• Call external scripts that use SiemensEngineering.dll (Openness) to extract XML/SCL from .zap18 archives.
• Read and write files in a working directory.
• Return a machine-readable JSON summary of changes and a human-friendly Markdown explanation.

When the agent asks you to diff two .zap18 files:

1. Locate the baseline and new .zap18 paths.
2. Run the external Openness diff script (e.g. tia_diff.bat baseline.zap18 new.zap18).
3. Parse the resulting JSON (FB/DB/hardware/networks changes).
4. Feed that structured data back to the agent for explanation.
