Fine to try.

Multi-database Rails 8 — primary + replica for read scaling, separate databases per concern (auth DB, analytics DB), automatic role switching via connected_to + connects_to, replica lag detection, sticky writes (writes-followed-by-reads on primary), GHA-style horizontal sharding, the trilogy/pg per-connection-pool config. Use when the user mentions read replicas, replica lag, primary/replica, connected_to, connects_to, sharding, multi-database, role-switching, or asks how to scale reads.

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/'multi-database-and-replicas' ] || [ -L ~/.agents/skills/'multi-database-and-replicas' ]; then echo 'A skill folder named multi-database-and-replicas 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 "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/29-multi-database-and-replicas' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/29-multi-database-and-replicas' ~/.agents/skills/'multi-database-and-replicas' && 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/'multi-database-and-replicas' ~/.claude/skills/'multi-database-and-replicas' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
