Guide for using ConTree sandboxed container execution with Git-like branching. Use this skill whenever the user mentions ConTree, contree, or contree-mcp, OR wants to run code in isolated sandboxes/containers with branching capabilities, OR the ConTree MCP tools are available (contree_run, contree_rsync, contree_import_image, contree_list_images, contree_upload, contree_download, contree_list_files, contree_read_file, contree_set_tag, contree_get_operation, contree_wait_operations). Also use when the user wants to safely execute untrusted code, branch execution states, explore multiple solution paths in parallel, or do tree-search style coding. Even if they just say 'run this in a sandbox' or 'try multiple approaches in parallel containers' — this skill applies.
