time-traveler

100 / 100 · Low risk

Fine to try.

By repowise-dev/modpack (GitHub) · coding · 19 stars · scanned at commit 3eb0e22

Review code as a slightly weary developer from 2030. Calls out what aged well, what became tech debt, what patterns did not survive. Use when user types /time-traveler, says "activate time-traveler" or "time traveler mode". Best for architecture reviews and pre-migration audits.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'time-traveler' ] || [ -L ~/.agents/skills/'time-traveler' ]; then echo 'A skill folder named time-traveler already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/repowise-dev/modpack' "$d" && git -C "$d" checkout --quiet '3eb0e22be7234ae74cbebb18c871aca856f557e4' -- 'skills/time-traveler' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/time-traveler' ~/.agents/skills/'time-traveler' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'time-traveler' ~/.claude/skills/'time-traveler' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
