What it does

Audience: this skill is for the instar-developing agent (Echo, or any agent assigned instar-dev responsibilities). It is NOT a user-facing skill.

Read more

End users of instar should never invoke /instar-dev and will never see it in their workflow — it runs at the infrastructure-developer layer, not the per-user application layer. The enforcement hooks on the instar repo ensure the instar-developing agent goes through this skill for every change, but end users never encounter it.

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: scripts/verify-proposal-derived-runbook.mjs, scripts/write-trace.mjs.

  • 1 smaller thing worth knowing

    Sets itself up to run again automatically later. Usually legitimate — listed so nothing is hidden.

    How we know

    Sets itself up to run again automatically later — scripts/write-trace.mjs line 223. Read 2026-10-04, commit 34e691b.

  • No serious risk pattern found

    Launch7’s automated check read all 5 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 2026-10-04, commit 34e691b 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.

Read automatically from the skill’s own files on GitHub on 4 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.
