WHAT IT DOES

What kicad.export_pdf does on Eda

AI agents use kicad.export_pdf to create or update resources in Eda — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Eda environment.

WHY IT NEEDS A POLICY

Why kicad.export_pdf needs a policy

The tool appears to export design data to PDF format, which creates a new file artifact. This is a write operation that generates output files from existing KiCad designs. Without a detailed description, the severity is assessed as low because PDF export is typically a read-based query of existing design data (not modifying the KiCad project itself), though it does create new artifacts.

From the tool's definition Tool name 'export_pdf' indicates file output generation. No description provided to determine exact behavior.
