What is magento-eav-attributes?

A guide to Magento 2's EAV attribute system. EAV, or Entity-Attribute-Value, stores flexible fields separately so products, categories, customers, and addresses can gain attributes without adding a database column each time.

Use it to add product, category, customer, or address attributes, create attribute sets, and work with Magento EAV data.

It helps you work with Magento's unusual attribute storage instead of treating it like a simple table. It explains the entities, typed value tables, and attribute sets involved.

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	$0.00057	$0.00930
Opus 5.5	$0.00023	$0.00372
Sonnet 5.5	$0.00011	$0.00186
Haiku 4.5	$0.00006	$0.00093

Security

Grade A, and why

magento-eav-attributes 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 1mo ago.

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.

Conceptual Architecture

What EAV Is

Entity-Attribute-Value is Magento's flexible storage pattern. Instead of one column per attribute, values are stored in separate typed tables. This allows merchants to add unlimited attributes without schema changes.

EAV Entities

Four entity types use EAV:

Products (catalog_product_entity)
Categories (catalog_category_entity)
Customers (customer_entity)
Customer Addresses (customer_address_entity)

EAV Table Structure

Each entity has typed value tables:

*_entity — base entity table (entity_id, sku, type_id, etc.)
*_entity_varchar — short text values
*_entity_int — integer values (including boolean, select)
*_entity_decimal — decimal/price values
*_entity_datetime — date/time values
*_entity_text — long text values

Attribute Properties

Key properties when creating attributes:

type — backend storage type (varchar, int, decimal, datetime, text, static)
input — frontend input type (text, textarea, select, multiselect, boolean, date, price, media_image, etc.)
label — human-readable name
required — is this attribute mandatory?
source — source model for select/multiselect options
backend — backend model for validation/processing
frontend — frontend model for display formatting
global — scope: store view, website, or global
visible — shown in admin forms
searchable — indexed for catalog search
filterable — available as layered navigation filter
comparable — shown in product comparison
used_in_product_listing — available in category listing pages

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.
