Sandboxed.sh Library Management
The Sandboxed.sh Library is a Git-backed configuration repo that stores reusable skills, agents,
commands, tools, rules, MCP servers, and workspace templates. Use the library-* tools to
read and update that repo.
When to Use
Creating or updating skills, agents, commands, tools, rules, or MCPs
Syncing library git state (status/sync/commit/push)
Updating workspace templates or plugins in the library
When NOT to Use
Local file operations unrelated to the library
Running missions or managing workspace lifecycle
Tool Map (file name + export)
Tool names follow the pattern <filename>_<export>.
