What problem does it solve? Moving large research data trees between HPC clusters (UChicago Midway, UMich Great Lakes) fails in non-obvious ways: missing consents, unlinked identities, hidden dotfiles, and transfers that silently retry until they expire. This Skill encodes the exact globus-cli setup, collection IDs, consent commands, and failure-mode diagnostics needed to complete cross-site transfers reliably. ## Core Features & Use Cases - Environment and account setup: Install globus-cli via mamba, link institutional identities, and grant data-access consents for every collection in one browser round-trip. - Batch-based transfers: Exclude large subdirectories precisely with batch files instead of error-prone --exclude filter rules, and submit resumable transfers with --sync-level mtime and --preserve-mtime. - Failure diagnosis: Interpret EXPIRED deadlines, LOGIN_DENIED, EndpointPermissionDenied, and zero-byte transfers using globus task event-list. - Use Case: You need to mirror a Midway3 project directory (including .git and .snakemake) to a UMich Turbo volume while skipping a huge Alignments folder; this Skill gives you the batch file, validation loop, and submission command. ## Quick Start Ask the AI to transfer a project directory from Midway3 to Great Lakes using globus-cli, excluding a specified large subdirectory.
