What is magento-module?

A development guide for Magento 2, Mage-OS, and Adobe Commerce modules, which are extensions that add or change ecommerce features. It covers module structure, database schemas, product attributes, checkout, orders, shipping, APIs, command-line tasks, testing, and debugging.

Use it to build or customize Magento modules, add database or product data, change checkout and totals, create APIs or scheduled tasks, and write tests. It also covers ecommerce-specific extension decisions.

It steers implementation toward current conventions and away from patterns that cause upgrade, compilation, or extension-review problems. It also helps choose the right way to extend existing Magento behavior.

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 staksoft/magento-claude-skills --skill magento-module

Clone the repo

git clone --depth 1 https://github.com/staksoft/magento-claude-skills

Made for: Claude Code.

Or install magento-skills, the plugin that ships this one along with the rest of its 3 skills.

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	$0.00316	$0.01848
Opus 5	$0.00158	$0.00924
Sonnet 5	$0.00063	$0.00370
Haiku 4.5	$0.00032	$0.00185

Security

Grade A, and why

magento-module 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scaffold.py), 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.

Magento 2 / Mage-OS Module Development

Expertise for writing Magento 2 modules that compile, pass phpcs --standard=Magento2, and follow current (2.4.x / Mage-OS) conventions. Magento has accumulated a decade of outdated tutorials; this skill exists because the obvious approach found in old blog posts is often wrong today. When in doubt, prefer the conventions here over patterns seen in older code.

Non-negotiable conventions (why they matter)

These are the mistakes that get extensions rejected from the marketplace and break upgrades:

Never use ObjectManager::getInstance() in your own code. Constructor injection only. ObjectManager hides dependencies, breaks compilation analysis, and fails code review. (Exceptions: factories/proxies generated by Magento may use it internally — that's fine.)
Declarative schema (db_schema.xml), never InstallSchema/UpgradeSchema scripts. Install scripts have been deprecated since 2.3 and make schema state unauditable.
Plugins over preferences. A preference (class rewrite) conflicts with every other module that rewrites the same class. A plugin composes. See the decision tree before choosing any extension mechanism.
View models, not block classes, for template logic. Custom blocks are legacy; a view model is a plain class injected into a template via layout XML.
Escape all template output with $escaper->escapeHtml() / escapeHtmlAttr() / escapeUrl(). Unescaped echo in .phtml is an XSS finding.
Service contracts first: depend on Api/ interfaces (e.g. ProductRepositoryInterface), not concrete Model classes, when consuming other modules.
Area-scope your di.xml: global etc/di.xml vs etc/frontend/di.xml vs etc/adminhtml/di.xml. A frontend-only plugin registered globally slows down everything.

Files

What ships with it

12 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.

magento-module is a skill published in the GitHub repository staksoft/magento-claude-skills (6 stars, last pushed 2mo ago), licensed MIT. It adds 316 tokens to every session and 1,848 once invoked, about $0.0016 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
