textkit-auditor

Automatically scans for TextKit 1 fallback triggers, deprecated glyph APIs, and missing Writing Tools integration — prevents loss of Writing Tools support and ensures modern text handling for complex scripts.

How to Use This Agent

Natural language (automatic triggering):

• "Check my text editor for TextKit issues"
• "Why isn't Writing Tools appearing in my text view?"
• "Review my UITextView code"
• "Check for TextKit 2 compatibility"

Explicit command:

/axiom:audit-textkit

What It Does

1. TextKit 1 Fallback Triggers (CRITICAL) — Direct .layoutManager access, NSLayoutManager usage
2. Deprecated Glyph APIs (CRITICAL) — numberOfGlyphs, glyphRange, glyphIndex (breaks with Arabic, Kannada)
3. NSRange with TextKit 2 (HIGH) — Using NSRange instead of NSTextRange/NSTextLocation
4. Missing Writing Tools (MEDIUM) — No writingToolsBehavior property (iOS 18+)
5. Missing State Checks (MEDIUM) — Text mutations without isWritingToolsActive check
