py

User preferences live in ~/Clawic/data/py/config.yaml (see Configuration); nothing else is stored on the user's machine. If you have data at an old location (~/py/ or ~/clawic/py/), move it to ~/Clawic/data/py/.

When To Use

• Writing or reviewing Python — scan Core Rules and Output Gates before committing
• Debugging wrong results without exceptions: state leaking across calls, aliased mutations, silent coercion
• Any traceback whose cause is not obvious in ten seconds, plus hangs, memory growth, and segfaults
• Environment and dependency work: venvs, lockfiles, editable installs, publishing, version upgrades
• Choosing a concurrency model, a data model, or a typing strategy, and living with the consequences
• Hardening a script into a tool: arguments, exit codes, logging, timeouts, retries, untrusted input
• Not for library-specific issues — pandas, numpy, django, fastapi, flask have their own skills
