Practical guides to adding AI features to PHP, WordPress and ecommerce systems without breaking production. Covers retrieval, tool calling, prompt injection, cost control, observability and running models on your own servers.
Canvas lets Sidekick edit a copy of your Shopify theme code from a chat. In a test with a 650-item Load more list, three precise prompts produced code that loaded nothing and three vague prompts worked. Here are seven checks to run in a browser before you publish.
On 20i shared hosting, StackProtect can refuse AI crawlers that Cloudflare allows. What to ask support, what one site’s ticket got back, how the counts changed afterwards and which crawler names were still refused.
When Cloudflare shows AI crawlers failing with 403 and 429, the refusal may have come from Cloudflare, the host or WordPress. How to tell them apart from response headers, the origin log and a careful spoofed user agent test.
PHP now has an official MCP SDK. This guide explains how to build a read-only Magento catalogue server with it, and why read-only has to live in the server code.

Working AGENTS.md files for WordPress, WooCommerce and Magento 2, how Claude Code and Codex load them, and what no instruction file can enforce.
A prompt edit can change a published returns figure without anyone noticing when. A gate that is allowed to refuse a merge is what closes that gap.
