File uploads in Ruby on Rails 8 with Active Storage — direct uploads to S3/GCS (skip the Rails server for the byte payload), variant configuration with image_processing + libvips, content-type and size validation, pre-signed URL safety (short TTLs, no public buckets by default), analyzer / previewer hooks, processing variants in background jobs (not the request thread), the service config for dev/test/prod.

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/'activestorage-uploads' ] || [ -L ~/.agents/skills/'activestorage-uploads' ]; then echo 'A skill folder named activestorage-uploads already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/13-activestorage-uploads' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/13-activestorage-uploads' ~/.agents/skills/'activestorage-uploads' && 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/'activestorage-uploads' ~/.claude/skills/'activestorage-uploads' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
