chmod-world

What problem does it solve?

This Skill sets up a world-accessible shared folder on HPC Lustre, ensuring cross-group read/write access and automatic propagation of permissive permissions to new files, addressing common admin restrictions on ACLs and inheritance.

Core Features & Use Cases

• Three-layer permission model: L1 target folder perms, L2 ancestor traversal, L3 new-file inheritance fallback.
• Cross-group sharing on HPC: supports world-writable collaboration while avoiding admin-level changes to ancestors.
• Use Case: Teams needing a shared workspace for large datasets where all members must read and write new content automatically.

Quick Start

Create the shared HPC folder and apply the world-writable permission workflow to ensure future files inherit permissive perms.
