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>.

Skills (library-skills.ts)

• library-skills_list_skills
• library-skills_get_skill
• library-skills_save_skill
• library-skills_delete_skill

Agents (library-agents.ts)

• library-agents_list_agents
• library-agents_get_agent
• library-agents_save_agent
• library-agents_delete_agent

Commands / Tools / Rules (library-commands.ts)

• Commands: library-commands_list_commands, library-commands_get_command, library-commands_save_command, library-commands_delete_command
• Tools: library-commands_list_tools, library-commands_get_tool, library-commands_save_tool, library-commands_delete_tool
• Rules: library-commands_list_rules, library-commands_get_rule, library-commands_save_rule, library-commands_delete_rule

MCPs + Git (library-git.ts)

• MCPs: library-git_get_mcps, library-git_save_mcps
• Git: library-git_status, library-git_sync, library-git_commit, library-git_push

Procedure

1. List existing items
2. Get current content before editing
3. Save the full updated content (frontmatter + body)
4. Commit with a clear message
5. Push to sync the library remote

• Keep names lowercase (hyphens allowed) and within 1-64 chars
• Use descriptive commit messages
• Check library-git_status before pushing
