Could you build this?
Partial The pipeline wrapper and graph output are buildable with an LLM and vision tools, but reliably reading scanned P&ID symbols and control loops needs domain-specific accuracy that vibe coding alone won't guarantee.
What it would actually take: The workflow can be built as a Claude skill that runs OCR or vision extraction and emits a graph schema. Accuracy on scanned diagrams depends on tuned symbol detection and line tracing, which needs computer vision work and labeled P&ID data. Correct instrument and control loop interpretation requires process engineering expertise to validate the output.
