Guidance for AI coding agents (Claude Code, etc.) working in this repo.

This is the Magento AI Starter — Daffodil: a Magento Open Source backend (at magento/) paired with a Daffodil Angular storefront (at daffodil/), pre-wired for GitHub Codespaces. It is a learning / prototyping baseline, not a production store.

Users drive the project by typing natural-language requests at the claude prompt. The sections below map the requests in README.md to the exact commands you should run.

Environment

• Working directory: /workspace (the repo root, containing magento/ + daffodil/)
• Runtime: VS Code devcontainer (.devcontainer/) backed by the magento2-devcontainer submodule. Brings up MariaDB, Redis, OpenSearch, RabbitMQ, Mailpit, php-fpm, and nginx as sibling Docker services.
• Magento root is /workspace/magento/. Run bin/magento from there (or use cd magento && bin/magento ...).
• Daffodil workspace is /workspace/daffodil/. Run Angular commands from there.
• Dependencies install automatically on first devcontainer up — updateContentCommand runs composer install in magento/ and npm ci in daffodil/ in parallel. Both directories are gitignored, so a fresh Codespace clone is missing them until this step runs.
• Magento is installed automatically right after deps — postCreateCommand pipes magento2-devcontainer/bin/setup-install.sh to bash. The upstream script waits for sibling services (db/rabbitmq/opensearch) to accept TCP connections, auto-detects the monorepo layout (Magento at magento/), and picks up $CODESPACE_NAME to set a working --base-url in Codespaces.
• Backend (Magento) is exposed on the forwarded nginx:8000 port.
• Storefront (Daffodil ng serve) is exposed on port 4200.
• The Angular dev server's proxy.conf.json forwards /graphql to http://nginx:8000 over the docker network. The storefront calls /graphql (relative), so the browser sees a single origin and no CORS configuration is needed.

Common user requests

"Start the Daffodil dev server" / "Show me the storefront"

cd daffodil
npx ng serve --host 0.0.0.0 --port 4200

This is a long-running command — leave it open. Codespaces forwards 4200 automatically. The first compile takes ~30 seconds; subsequent edits hot-reload.

"Install Magento" / "Reinstall Magento"

Magento is already installed on first launch. If the user explicitly asks to reinstall (or setup:install was interrupted), wipe the partial state and re-run the upstream installer:

rm -f magento/app/etc/env.php magento/app/etc/config.php
.devcontainer/magento2-devcontainer/bin/setup-install.sh | bash

The upstream script prints the bin/magento setup:install command with the devcontainer's default service hostnames, prepends a cd "./magento" for the monorepo layout, and (in Codespaces) sets --base-url to the forwarded :8000 URL.

"Add a banner to the homepage" / Frontend changes

Edit Angular components in daffodil/src/app/. The Daffodil schematic laid out:

• daffodil/src/app/daff/pages/home/home.component.ts — homepage
• daffodil/src/app/daff/pages/not-found/not-found.component.ts — 404
• daffodil/src/app/daff/product/components/product-list/ — listing
• daffodil/src/app/daff/product/components/product-page/ — PDP
• daffodil/src/app/daff/navigation/components/navigation.component.ts — nav

The dev server hot-reloads on save — no command needed after editing.

For new components, use the Angular CLI:

cd daffodil
npx ng generate component features/<name>

Backend (Magento) changes

• Run bin/magento from /workspace/magento/.
• After changes to app/etc/config.php or DI: bin/magento setup:upgrade && bin/magento cache:clean.
• After module changes: bin/magento setup:upgrade && bin/magento cache:flush.
• GraphQL schema lives under magento/vendor/magento/module-*-graph-ql/etc/schema.graphqls. Schema changes need bin/magento cache:clean.

"Save a checkpoint" / "Save this"

Commit everything with a Conventional Commits prefix. Pick the label from the nature of the change:

• chore: — setup, config, no user-visible change (no release bump)
• docs: — documentation only (no release bump)
• fix: — bug fix (patch bump)
• feat: — new user-visible feature (minor bump)

git add -A
git commit -m "<type>: <short description>"

release-please reads these labels and proposes versioned releases on push.

"Save this and push it to GitHub"

Commit (as above) and then:

git push

Conventions

• Magento admin credentials are dev defaults set by upstream setup-install.sh: admin / admin123. These are for the devcontainer only — never ship them.
• Daffodil ↔ Magento wiring lives in daffodil/src/app/app.config.ts. The provideMagentoDriver({ uri: "/graphql" }) URI is intentionally relative — the proxy in daffodil/proxy.conf.json handles routing to the Magento backend. Don't switch this to an absolute URL.
• CI: .github/workflows/check-store.yml runs PHPUnit, the Magento coding standard, and a smoke test against magento/ on every push and PR. Don't push backend changes that you haven't at least tried to build locally.
• Dep refresh — composer.json or package.json edits don't auto- re-install. After changes, run composer install in magento/ or npm install in daffodil/ manually. (Rebuilding the container also re-runs updateContentCommand.)

Out of scope

This starter is explicitly not production-ready:

• Default admin password (admin123) is a known dev default.
• Magento ships with Magento_TwoFactorAuth enabled. Set up TOTP via the Mailpit-caught activation email on first admin login (see README step 6) — or bin/magento module:disable Magento_TwoFactorAuth Magento_AdminAdobeImsTwoFactorAuth if a user explicitly wants 2FA off for dev.
• Magento is in default mode out of the install (no DI compile, no static-content deploy). bin/magento deploy:mode:set developer if the user wants live template reloads / friendlier errors.
• No HTTPS — the storefront and admin both run over plain HTTP inside the devcontainer.
• The Angular dev server is ng serve, not a production build. The proxy approach for /graphql only works behind ng serve; for production, the storefront would be served as static files behind a reverse proxy (or with graycore/magento2-cors configured to allow the storefront's origin).

If the user asks about taking this to production, flag the gap honestly rather than papering over it.
