BACH CodeCommander
This is a code utility belt that gives Claude 17 specialized tools for working with source files. You get AST-based Python analysis that extracts classes and methods with complexity metrics, automatic JSON repair that fixes trailing commas and BOMs, import organization per PEP 8, and encoding fixes for Mojibake across 27 patterns. It also handles format conversion between JSON, CSV, YAML, TOML, XML, and INI, runs unified diffs between files, tests regex patterns with match previews, and exports Markdown to HTML or PDF. Seven tools overlap with the author's FileCommander server for convenience, so you can use either depending on whether you need filesystem operations or code intelligence. All destructive operations support dry run mode and automatic backups.
