What is laravel-spatie-event-sourcing?

A guide for building Laravel applications with event sourcing using Spatie’s event-sourcing package. Event sourcing records changes as events so an application can reconstruct an entity’s history.

Use it when setting up or debugging Spatie event sourcing, designing aggregates and events, creating projectors or reactors, and generating tested domain code.

It gives you a structured design-and-test process for event-sourced Laravel features and helps avoid unclear event, aggregate, and projection designs.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add albertoarena/claude-laravel-event-sourcing --skill laravel-spatie-event-sourcing

Clone the repo

git clone --depth 1 https://github.com/albertoarena/claude-laravel-event-sourcing

Made for: Claude Code.

Or install laravel-spatie-event-sourcing, the plugin that ships this one along with the rest of its 1 skill.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00150	$0.01560
Opus 5	$0.00075	$0.00780
Sonnet 5	$0.00030	$0.00312
Haiku 4.5	$0.00015	$0.00156

Security

Grade A, and why

laravel-spatie-event-sourcing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify-setup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Laravel Spatie Event Sourcing — Skill

Generate event-sourced domain code for Laravel using spatie/laravel-event-sourcing, following a two-gate workflow: Design first, then implement with tests.

Quick reference

references/design-heuristics.md — Event naming, aggregate boundaries, projector/reactor rules, anti-patterns
references/adr-template.md — ADR template for Gate 1
references/tdd-patterns.md — Pest and PHPUnit test patterns
references/commands-pattern.md — Command + handler patterns (plain and bus-dispatched)
references/spatie-api-cheatsheet.md — Key Spatie ES classes and methods
assets/templates/*.stub — Code generation stubs

Project bootstrap (one-time, automatic)

On first invocation in a project, run scripts/verify-setup.sh from this skill's directory. It checks:

PHP 8.2+ is installed (required by spatie/laravel-event-sourcing v7)
spatie/laravel-event-sourcing is in composer.json
The stored_events and snapshots tables exist (migrations have run)
config/event-sourcing.php has been published
A test framework is installed (Pest preferred, PHPUnit fallback)

If anything is missing, print the single command that fixes it and stop. Do not auto-install packages or run migrations on behalf of the user — they need to confirm first.

If everything passes, check for .claude/event-sourcing.md in the project root. If it doesn't exist, ask the user one configuration question:

"I'll create a project config at .claude/event-sourcing.md. Two quick choices:

Command dispatch style: plain handler classes invoked directly, or Laravel's command bus (Bus::dispatch)?

Test framework: Pest or PHPUnit?"

Write their answers to that file. On future invocations, read it silently and proceed.

The two-gate workflow

This skill operates in two gates with a hard stop between them. The user must approve the design before any code gets written.

Gate 1 — Design (ADR)

Start with domain analysis. Ask 3–5 focused questions (skip any the user already answered):

What ships with it

21 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
