Problem Statement

A skill for directly editing Apple Keynote files, similar to the existing PPTX skill, would be very useful for Mac users.

Currently, working with Keynote presentations requires converting to PPTX first, which loses Keynote-specific formatting and features. Native .key file support would enable direct slide manipulation without format conversion.

The main challenge is that Keynote uses IWA (iWork Archive) with binary protobuf encoding rather than the XML-based ZIP structure of PPTX, but the value for Mac-centric workflows would be significant.

Use case: Commercial presentations and academic lecture slides increasingly rely on Keynote — editing content, restyling elements, and extracting formulas directly without round-tripping through PowerPoint format would be a major productivity gain.

Proposed Solution

direct editing of keynote just as for pptx
