Enforce Formatting on Every File Edit

Your team requires all Python files to be formatted with Black before they're shared. You added a note in CLAUDE.md asking Claude to run Black after edits — but it occasionally skips it. That's expected: CLAUDE.md instructions are best-effort suggestions, not guarantees. A post-tool-use hook is different. It fires automatically after every file edit, every single time, with no exceptions.

The team's project is already in your working directory at /home/repl/climate-analysis/..
