Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs OARS Agent Readiness

Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want: frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers. Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem, and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php and praying. I wanted a place where small bits of code are organized, safe, AI-assisted, and reusable everywhere. Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places: AI Engine: your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer. Workflow Engine: your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code. REST / External tools: give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 Snippets Manager Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets, all in one clean dashboard with tags, search, scope filters, and priorities. 🪄 AI-Assisted Coding Describe what you want in plain English and let AI Engine write the snippet: code, name, arguments, and scope included. Refine existing code or implement it straight from your comments. 🤖 Functions as AI Tools Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk. 🔀 Functions as Workflow Steps Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas. 🌐 External Access (REST) Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs. 🛡️ Safe Mode A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence. ⏰ Scheduling Run a snippet daily at a chosen time via WP-Cron (reports, cleanups, syncs) without touching the server crontab. 🧱 Code Blocks & Shortcodes (Pro) Drop PHP or JS straight into a post or page with a Gutenberg block or the [code-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults. Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard. ✨ The big idea: write once, use everywhere This is what makes Code Engine different. A Function snippet is not just code you call from other code. It’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once: 1. As an AI tool, for chatbots and AI agents With AI Engine active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents (Claude, Claude Code, ChatGPT, OpenClaw) can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill. 2. As a workflow step, for automation With Workflow Engine, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps: an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration. 3. As a REST endpoint, for the outside world Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed.

AI agents and AI crawlers are increasingly the ones visiting your site — ChatGPT, Claude, Perplexity, Gemini and their bots (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, anthropic-ai, GoogleBot-Extended) research, recommend, and act on behalf of users. Traditional SEO doesn’t cover this. OARS is AI readiness (sometimes called AI SEO, Generative Engine Optimization / GEO, or Answer Engine Optimization / AEO): it publishes the machine-readable signals AI systems need to find, read, and correctly represent you. The Open Agent Readiness Standard (OARS) by Knov.ai defines what makes a site machine-operable. This plugin handles the low-hanging fruit automatically and scores the rest. Free oars.json — a machine-readable knowledge declaration served at your domain root, auto-populated from your site title, tagline, categories, and pages. llms.txt — a clean Markdown summary for LLMs (guaranteed to meet the 200-word minimum). AI bot directives — adds rules for GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, anthropic-ai and GoogleBot-Extended to robots.txt. Schema.org identity — injects Organization JSON-LD on your homepage. Content-Signal headers — declares your AI usage preferences (search / input / training). Live readiness score — the scorecard self-fetches your real URLs and headers, so it reflects what agents actually see; every gap is flagged with a fix and a proof link. Level 0 baseline — security headers, optional report-only CSP, Link headers, and CORS on your agent files. /llms-full.txt, /.well-known/oars.json, sitemap fallback and a guided first-run setup wizard. Bring-your-own LLM (optional) — connect OpenAI, Anthropic, or Google to enrich your identity fields and llms.txt narrative. Pro (separate add-on) OARS Pro is a separate plugin you install alongside this one (available from tylerewillis.com). It adds: Agent API (Level 3) — read-only REST endpoints, OpenAPI 3.1 contract, and an A2A agent card. Web Bot Auth signing-key directory and Agent Skills discovery (.well-known). Level 4a machine-readable product catalog from WooCommerce. Full Level 1–2 scoring with per-check remediation. Weekly monitoring with an email alert if your score drops. Advanced Schema.org — Service, Product, and FAQPage auto-generated from your pages and WooCommerce catalog. Markdown content negotiation (Accept: text/markdown) for agents. Scheduled regeneration as your content changes. WP Multisite / network management. One-click submission to the Knov.ai directory + verification ID. OARS compliance badge shortcode. Pro is licensed per site or per agency. Learn more at tylerewillis.com/tools/oars-for-wordpress. External services The OARS Agent Readiness plugin works fully without contacting any third party. Some optional features connect to external services only when you enable them: AI enrichment (optional). If you add an API key for OpenAI, Anthropic, or Google, the plugin sends the text content you ask it to process (e.g. your page titles and excerpts) to that provider to generate llms.txt narrative, identity suggestions, or FAQ content. Data is sent only when you click a generate button. Review each provider’s terms and privacy policy: OpenAI (https://openai.com/policies/), Anthropic (https://www.anthropic.com/legal/privacy), Google (https://policies.google.com/privacy). Readiness self-check. The dashboard score fetches your own site’s public URLs (e.g. /llms.txt, /oars.json, your homepage) to verify what agents actually receive. These requests go to your own domain, not a third party. (The optional OARS Pro add-on validates a license key with tylerewillis.com; that disclosure ships with the Pro plugin, not this free plugin.) The “Scan headers”, “PageSpeed”, and “Validate schema” buttons simply open external tools in a new browser tab; OARS does not send your data to them from the server.
