Linter

The linter catches automation-hostile VBA and syntax patterns that can block agents or surface modal dialogs.

Declaration, member-access, error-handling, Excel object, and procedure-scope checks are backed by tree-sitter-vba, so findings can distinguish comments and strings from executable code, module-level declarations from procedure-local declarations, and individual declarators in one Dim statement.

Rules include:

• Missing Option Explicit
• Select and Activate
• Broad On Error Resume Next
• Implicit Variant risks
• Public module fields
• Unqualified Excel object access
• Error-handler fallthrough
• Multiple declarator clarity
• Optional cleanup, shadowing, unused symbol, callback, Range.Find, Resume, and nested With checks
• GUI boundaries such as file pickers, modal dialogs, UserForms, message pumps, and external process launches
• Syntax-safety findings that prevent VBE compile dialogs before push or run
