The repo-hash is computed in Python (not shasum) so this is identical across macOS, Linux, and Windows — no BSD/GNU coreutils dependency.

REPO_HASH=$(python3 -c "import hashlib,subprocess;t=subprocess.run(['git','rev-parse','--show-toplevel'],capture_output=True,text=True).stdout.strip();print(hashlib.sha1(t.encode()).hexdigest()[:12] if t else '')")

# Hooks and skills share one deterministic cache base. Override with
