Skill Installer

What it does

When your agent uses it

• Tasks that involve Skill management

Example prompts

• “安装skill”
• “帮我安装xxx”
• “我下载了skill，路径是xxx”
• “/skill-installer”

Requirements

• Pre-approved tools (allowed-tools): Bash(git *), Bash(curl *), Bash(wget *), Bash(mv *), Bash(cp *), Bash(mkdir *), Bash(ls *), Bash(unzip *), Read, Grep, Glob

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1自动Git安装
2. 2代理自动选择
3. 3路径标准化

What it can do on your machine

Read from SKILL.md and the folder at commit 24bde40. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(git *)
  • Bash(curl *)
  • Bash(wget *)
  • Bash(mv *)
  • Bash(cp *)
  • Bash(mkdir *)
  • Bash(ls *)
  • Bash(unzip *)
  • Read
  • Grep

  …and 1 more on the same allowed-tools line.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • apt
  • git
  • yum
  • brew
  • choco
  • winget
  • dnf
  • curl
  • wget

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • github.com
  • gh-proxy.com
  • brew.sh
  • mirror.ghproxy.com
  • gitclone.com
  • bgithub.xyz

  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

Skill Installer loads about 3.4k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 74 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~30

When it runs · the whole SKILL.md, loaded when a task matches

~3.4k

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

• NoteRuns commands with sudoSKILL.md:65

  sudo apt update && sudo apt install -y git

• NoteRuns commands with sudoSKILL.md:67

  sudo yum install -y git

• NoteRuns commands with sudoSKILL.md:69

  sudo dnf install -y git

• NoteRuns commands with sudoSKILL.md:71

  sudo pacman -Sy git

• NoteRuns commands with sudoSKILL.md:414

  # sudo apt update && sudo apt install -y git

• NoteRuns commands with sudoSKILL.md:456

  sudo apt update && sudo apt install -y git

• NoteRuns commands with sudoSKILL.md:458

  sudo yum install -y git

• NoteRuns commands with sudoSKILL.md:551

  echo "  1. 使用sudo: sudo install-skill"

• NoteRuns commands with sudoSKILL.md:575

  echo "  1. 安装Git: sudo apt install git"

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 74 words (~3,442 tokens).
