What it does

Find out why something behaves the way it does, then — when a change is implied — fix the cause and verify it. Investigation and remediation are one method, not two skills: splitting them meant writing a plan to disk so the other half could read it back, and a plan that survives a handoff is a plan that went stale.

When your AI uses it

Use for any failure

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

  • Includes 2 scripts

    Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.

    How we know

    Found in the skill’s folder: references/condition-based-waiting-example.ts, references/find-polluter.sh.

  • No known risk pattern found

    Launch7’s automated check read all 7 text files in this skill and matched none of its 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 cf30fd8 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 rodolfochicone/rc-project: 2026-08-06 (60 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

Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.

  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.

This skill ships 2 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.

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
