Developer Docs#

Under-the-hood documentation for developers extending drawing_tools.

These documents provide low-level details about internal systems and extension mechanisms. They are intended for contributors and developers building on top of the library.

The repository also ships Agent Skills for AI coding assistants under src/drawing_tools/claude_skills/ — see the INSTALLING_SKILLS.md file there.

Note

This section assumes familiarity with the user-facing documentation. Start with the Features Guides if you’re new to the library.
