/check-sizes — Audit file sizes against limits

Scan source files and flag any that exceed the file size limits defined in CLAUDE.md.

Steps

1. Read the file size limits from CLAUDE.md (File Size Limits section)

2. Count lines in all source files:

   • Headers/interfaces: check against header limit
   • Implementation files: check against implementation limit
   • Total per module (header + impl): check against total limit

3. Report in this format:

   FILE SIZE AUDIT
   ===============
   
   Within limits:  [count] files
   Over limit:     [count] files
   
   [If any over limit:]
   OVER LIMIT:
     [file] — [lines] lines ([limit] limit, [amount] over)
       Suggestion: [splitting strategy from CLAUDE.md]
   
   APPROACHING LIMIT (>80%):
     [file] — [lines] lines ([limit] limit)
   

Arguments

• No arguments: scan all source directories
• $ARGUMENTS: scan specific directory

Notes

• Use the file size calibration table in CLAUDE.md for the correct limits per language
• Suggest specific splitting strategies from the Splitting Strategies table
