Event sourcing patterns for functional TypeScript — persist state as an append-only log of past events and rebuild it by folding them. Use when implementing a Decider write model, an event store, projections and read models, event versioning, or snapshots. Builds on the Decider from domain-driven-design and the ports/adapters from hexagonal-architecture. Do NOT reach for it on CRUD, or when an audit log or the outbox pattern already suffices.

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/'event-sourcing' ] || [ -L ~/.agents/skills/'event-sourcing' ]; then echo 'A skill folder named event-sourcing already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/citypaul/.dotfiles' "$d" && git -C "$d" checkout --quiet 'cd4028d57d6e4e95814f7b8ee55ca13c23a9c2f0' -- 'claude/.claude/skills/event-sourcing' && mkdir -p ~/.agents/skills && cp -R "$d"/'claude/.claude/skills/event-sourcing' ~/.agents/skills/'event-sourcing' && 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/'event-sourcing' ~/.claude/skills/'event-sourcing' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
