When your AI uses it

Use when someone want

You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.

What it can touch

  • No script files in its folder

    Its folder holds text, not programs. It changes how your AI works; it does not bring code of its own.

    How we know

    Listed the 2 files in the skill’s folder on GitHub; none is a script or program.

  • Lets your AI use some powerful tools without asking, while the skill is in use

    While the skill is working, Claude Code will not ask before using these tools.

    How we know

    SKILL.md line 1: “allowed-tools: Read, Glob, Grep, Agent, Bash(git *), Bash(gh *), Bash(find *), Bash(bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh")”. Read 2026-10-05, commit abba73a.

    SKILL.md, line 1 ↗
  • Runs a command by itself, without asking, as soon as the skill loads

    Claude Code runs a command written into the skill the moment the skill is opened, before your AI reads it — no approval is asked unless you have a rule blocking it.

    How we know

    SKILL.md line 23 (and 8 more in that file): “which git 2>/dev/null || echo "not installed"”. Read 2026-10-05, commit abba73a.

    SKILL.md, line 23 ↗
  • No serious risk pattern found

    Launch7’s automated check read all 2 text files in this skill and matched none of its serious risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.

    How we know

    Read 2026-10-05, commit abba73a by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.

  • Recently maintained

    Its repository has had changes recently.

    How we know

    Last push to testdouble/han: 2026-10-01 (4 days before the scan).

Read automatically from the skill’s own files on GitHub on 5 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check

Add it to your AI

Supported. Upload it once in Claude’s settings. Works on every plan, including Free.

  1. Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.

  2. In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.

  3. Make sure code execution is switched on (Settings → Capabilities). Skills need it.

  4. Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.

How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end
