# cleanup-claude-dirs.sh — Remove .claude/ directories from all repos
#
# .claude/ is local workspace config (MCP settings, worktrees) and should
# never be committed. This script:
#   1. Checks if .claude/ exists in the repo via Gitea API
#   2. Deletes all files in .claude/ via API
#   3. Ensures .claude/ is in .gitignore
#
# Usage:
#   cleanup-claude-dirs.sh              # all repos
#   cleanup-claude-dirs.sh MokoOnyx     # one repo
