At a glance

Reads and updates the Sandboxed.sh Library, a git-backed store of skills, agents, commands, tools, rules and MCP servers, through its library tools.

  • Works in 5 steps: List existing items → Get current content before editing → Save the full updated content… → …
  • Saving a new skill or agent into the Sandboxed.sh Library
  • SKILL.md covers When to Use, When NOT to Use, Tool Map (file name + export) and Procedure, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

The Sandboxed.sh Library is a git-backed configuration repo that holds reusable skills, agents, commands, tools, rules, MCP server definitions and workspace templates. This skill maps out the library tools that read and write it: list, get, save and delete for each item type, a pair for reading and saving MCP configuration, and git tools for status, sync, commit and push.

The procedure is to list existing items, fetch the current content before editing, save the full updated content with its frontmatter and body, commit with a clear message and push to the library remote. It also describes the file layout for each type: a SKILL.md inside a folder per skill, Markdown files with frontmatter for agents, commands and rules, a TypeScript file for each tool, and a servers JSON file for MCPs.

It is not meant for local file work unrelated to the library, nor for running missions or managing the lifecycle of workspaces; those fall outside what the library tools cover.

When your agent uses it

  • Saving a new skill or agent into the Sandboxed.sh Library
  • Updating an existing command, tool or rule and pushing the change
  • Syncing the library's git state or editing MCP server entries

Example prompts

  • “Save this workflow as a new skill in the Sandboxed.sh library.”
  • “List the agents in the library, then update the reviewer agent's description.”
  • “Commit and push my library changes with a clear message.”

Requirements

  • Access to the Sandboxed.sh Library tools and its git remote

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  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

What it can do on your machine

Read from SKILL.md and the folder at commit 960b656. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml, typescript and json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sandboxed.sh Library Management loads about 931 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~931

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 201 words (~931 tokens).

“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.”
