I just migrated a production Python codebase to Go using Claude Code as the primary coding agent. The project was Kodit, an MCP server for indexing code repositories. The code compiled, the tests passed, but it didn’t work. No surprise there right? It took a total of about 2 weeks to get right. The real value of this experience was learning what goes wrong when you let an AI do a cross-language migration. Dead code accumulation, phantom features rebuilt from deprecated references, missing integration tests, context window limits causing half-finished refactors. Claude is a powerful but literal executor. The gaps in your design become the bugs in your system. I wrote up the full methodology, the automation script, and everything that went wrong so you can learn from my mistakes. https://winder.ai/python-to-go-migration-with-claude-code/ submitted by /u/philwinder
