/debug

Debug Move Code

Parse compiler errors from stderr and suggest fixes.

Usage: /move:debug

Instructions

1. Check for recent compiler output:

   • Look for error messages in the terminal/output
   • Parse the error location (file:line:column)
   • Identify the error type

2. Common error patterns and fixes:

   Ability Errors:

   • "does not have the 'key' ability" → Add has key to struct
   • "does not have the 'store' ability" → Add has store to struct
   • "cannot copy" → Add has copy or use & reference

   Borrow Errors:

   • "cannot borrow" → Check mutability, use borrow_global_mut
   • "still borrowed" → Ensure reference is dropped before re-borrow

   Type Errors:

   • "expected X, found Y" → Check function signatures
   • "mismatched types" → Verify generic parameters

   Move Errors:

   • "cannot move out" → Use move_from or copy the value
   • "resource already exists" → Check exists<T>(addr) first

   Access Errors:

   • "function is not public" → Add public or public(friend)
   • "module not found" → Check Move.toml dependencies

3. Read the relevant source file at the error location

4. Use search_framework if the error involves framework types

5. Provide:

   • What the error means
   • The specific fix with code
   • Why this fixes the issue

Run Compiler

To get fresh errors, suggest running:
