The Simple Version
AI tools do better work when you give them the right background first
MCP helps AI tools connect to other tools and context, like a universal adapter. AGENTS.md gives AI coding agents instructions for your project, like a project instruction manual. CLAUDE.md gives Claude-specific notes. Context engineering means preparing the right background, rules, examples, and limits before asking AI to do work.
The goal is simple: fewer mistakes, safer edits, and better outputs.
Who this course is for
This AGENTS.md guide is for people who use AI tools but do not want to become full-time developers just to get safer, clearer results.
Turn your content process, style rules, and examples into instructions an assistant can follow.
Give AI coding agents for beginners a clear picture of your product, audience, and risk areas.
Protect SEO-critical pages, analytics, tracking scripts, and brand voice while still moving faster.
Use plain language to explain your project before asking Codex, Claude Code, Cursor, or Replit to edit files.
Learn the difference between a one-off prompt and reusable AI project instructions.

Course Lessons
10 short lessons for safer AI work
Open each lesson to see a plain-English explanation, why it matters, a beginner example, a copyable prompt, and a simple action step.
Plain-English explanation: AI tools usually know only what is in the current chat, file, or task. If you do not tell them your project rules, they may guess.
Why it matters
Missing context can lead to broken layouts, changed tracking code, removed SEO text, or edits that do not match your brand.
Beginner example
You ask an AI to improve a WordPress page. It changes the design but removes a copy button because it did not know that button was important.
Copy this prompt
Before editing anything, ask me what project context, protected areas, and testing steps you need to know.Mini action step: Write down three things your AI tool should always know about your project.
Plain-English explanation: Prompting is the request you type now. Context engineering is the setup you give the AI before the request, including background, examples, rules, and limits.
Why it matters
A great prompt can still fail if the AI does not understand the project. Context makes your prompt safer and more specific.
Beginner example
Instead of only saying “improve this page,” you also say who the page is for, what sections to keep, and what the AI must test.
Copy this prompt
Use the project instructions before you make changes. If the instructions do not cover this task, ask me before guessing.Mini action step: Pick one recurring AI task and list the background information it needs every time.
Plain-English explanation: MCP means Model Context Protocol. Think of it as a shared connector that can help AI tools access approved context from other tools.
Why it matters
As AI tools become more useful, they often need access to files, docs, tickets, or other systems. MCP is one way to make those connections more consistent.
Beginner example
Instead of copying every detail into a chat, an AI tool may connect to the right source of context when it is allowed to.
Concrete example
Imagine you ask an AI assistant to improve a landing page. Without connected context, you may need to paste the page copy, brand notes, SEO rules, analytics goals, and protected areas into the chat manually. With approved MCP-style connections, an AI tool may be able to access the right files, docs, or tools directly, but only when you have safely granted that access.
More access can mean more usefulness, but it also means permissions matter.
Copy this prompt
Explain which tools or files you can access for this task, and tell me what context you still need from me.Mini action step: Write one sentence describing what outside context would help your AI assistant most.
Safety Checklist
Beginner MCP Safety Rules
MCP is powerful because it can help AI tools connect to outside tools, files, apps, APIs, databases, docs, and workflows. That is useful, but beginners should treat those connections like browser extensions, plugins, or app integrations, not like ordinary prompts.
- Only use MCP servers from trusted sources.
- Review what permissions a server asks for before connecting it.
- Do not expose API keys, passwords, private files, payment data, customer data, analytics credentials, login credentials, or sensitive business information.
- Use least-privilege access: only give the AI the minimum access it needs for the task.
- Keep human review before anything that edits files, sends messages, changes a live website, touches money, accesses private data, changes tracking, changes SEO metadata, changes security settings, or uses external tools.
- Remember that instruction files like AGENTS.md and CLAUDE.md guide AI behavior, but they are not perfect safety systems.
Plain-English explanation: AGENTS.md is a text file that tells AI coding agents how to work in your project. Codex reads AGENTS.md, and other coding agents may use it as a general project instruction file.
Why it matters
It turns repeated instructions into a reusable project manual, so you do not have to explain the same rules every time.
Beginner example
Your AGENTS.md can say: keep CSS scoped, do not edit payment code, test mobile layout, and ask before publishing.
Copy this prompt
Create a beginner-friendly AGENTS.md file for this project. Include project overview, allowed changes, protected areas, testing steps, and approval rules.Mini action step: Create a rough list of what your AI tool can and cannot change.
Plain-English explanation: CLAUDE.md is the file Claude Code uses for persistent project instructions. Claude Code reads CLAUDE.md, not AGENTS.md directly, so CLAUDE.md is the best place for Claude-specific notes.
Why it matters
Different AI tools may look for different instruction files. Keeping general rules and tool-specific notes clear helps avoid confusion.
Beginner example
AGENTS.md can hold your general project rules. CLAUDE.md can import or reference those rules and add Claude-specific notes, such as when to ask before editing sensitive files.
Copy this prompt
Create a CLAUDE.md file that references my general AGENTS.md rules and adds Claude-specific notes, including when to ask before editing sensitive files.Mini action step: If you use Claude Code, write one Claude-specific instruction you want it to remember.
Plain-English explanation: Good project instructions explain the project, audience, tools, important files, allowed changes, protected areas, testing steps, and approval rules.
Why it matters
The AI needs both permission and limits. Clear instructions reduce accidental changes and make review easier.
Beginner example
For a landing page, the AI can edit headline copy and CSS, but it cannot change analytics tags or legal disclaimers.
Copy this prompt
Turn my notes into clear AI project instructions with sections for overview, audience, allowed changes, protected areas, testing, and approvals.Mini action step: Fill in the sentence: “The AI can change ___, but must not change ___.”
Plain-English explanation: Your first file does not need to be perfect. Start with a short, useful version and improve it as you learn what the AI gets wrong.
Why it matters
A simple instruction file is better than no instruction file. It gives the AI a starting point before it touches your work.
Beginner example
Create project-instructions.md with your website name, audience, goal, protected areas, and testing checklist.
Copy this prompt
Ask me simple questions, one at a time, then create my first project-instructions.md file from my answers.Mini action step: Use the generator on this page to create your first draft.
Plain-English explanation: WordPress AI coding instructions should say where the code will be used, what theme or page is involved, and what must remain untouched.
Why it matters
WordPress pages often include theme styles, plugins, analytics, forms, and SEO elements. The AI needs to know what is safe.
Beginner example
If you paste HTML into a Custom HTML block, tell the AI to avoid global CSS like body, h1, or button unless scoped to your wrapper.
Copy this prompt
Create WordPress AI coding instructions for this page. Include the page URL, theme if known, Custom HTML block rules, SEO rules, protected areas, and testing checklist.Mini action step: Write your website URL and the exact page or block the AI is allowed to edit.
Plain-English explanation: Testing instructions tell the AI what to check before it says the work is done. They should cover buttons, mobile layout, links, forms, and visual issues.
Why it matters
AI tools can create changes that look fine in code but fail in the browser. Testing instructions catch more of those problems.
Beginner example
After adding an accordion, the AI should click each item, test keyboard use, and check the mobile view.
Copy this prompt
Before you finish, test every button, link, form field, accordion, copy action, and mobile layout. Tell me what passed and what you could not test.Mini action step: Add three testing steps to your instruction file.
Plain-English explanation: Dangerous changes are edits that could affect money, logins, customer data, legal pages, tracking, security, or live theme files.
Why it matters
AI can move quickly. Clear safety rules slow it down where a human review point is needed.
Beginner example
Your instruction file can say: do not edit checkout, login, database, analytics, or legal pages without permission.
Copy this prompt
Before making this change, identify whether it touches payment, login, database, customer data, legal, analytics, tracking, SEO-critical, or security areas. Ask before editing any risky area.Mini action step: Add a “Protected Areas” section to your instruction file.

Source and Accuracy Note
MCP, AGENTS.md, Claude Code, Codex, and AI coding agents can change over time. This course teaches durable beginner concepts, not every advanced implementation detail, so check official documentation before using these tools in production, sensitive workflows, client work, or risky website changes.
Who should use which file?
You do not need every file on day one. Choose the simplest option that matches your tool.
When you use Codex or another AI coding agent and want general project instructions.
When you use Claude Code and want persistent Claude-specific project notes. It can import or reference AGENTS.md when you already keep general rules there.
When you want a plain-language instruction file that works even if your tool does not look for a special filename.

FAQ
Questions beginners ask about MCP, AGENTS.md, and context engineering
What is MCP in simple terms?
MCP is a standard way for AI tools to connect to approved tools and context. A simple analogy is a universal adapter.
Do I need to know code to understand MCP?
No. You only need the basic idea: MCP helps AI tools connect to useful context instead of relying only on what you type.
What is AGENTS.md?
AGENTS.md is a project instruction file for AI coding agents. It tells the AI how to work, what it can change, what it must protect, and how to test.
Is AGENTS.md only for developers?
No. Non-technical builders can use AGENTS.md to explain goals, rules, protected areas, and review steps in plain language.
Is AGENTS.md the same as a prompt?
No. A prompt is usually one request you type in the moment. AGENTS.md is reusable project context that an AI coding agent can read before working.
Where do I put an AGENTS.md file?
For coding projects, AGENTS.md usually belongs near the root of the project so the AI agent can find the general instructions. Non-technical users can keep the same information in project-instructions.md.
What is CLAUDE.md?
CLAUDE.md is a Claude-specific instruction file often used with Claude Code. It can hold notes that are meant for Claude in particular.
What is the difference between AGENTS.md and CLAUDE.md?
AGENTS.md is useful for general AI coding agent instructions. Claude Code reads CLAUDE.md for persistent project instructions and Claude-specific notes.
Should I use both AGENTS.md and CLAUDE.md?
Use AGENTS.md for general AI coding agent instructions. Use CLAUDE.md when you use Claude Code and want Claude-specific notes. Some projects use both.
What is context engineering?
Context engineering means giving AI the right background, rules, examples, and limits before asking it to do work.
Is MCP safe for beginners?
MCP can be useful, but beginners should be careful. Only connect trusted servers, review permissions, avoid sensitive data, and keep human approval for risky actions.
Can I use this with WordPress?
Yes. You can document WordPress pages, Custom HTML blocks, theme limits, SEO rules, and testing steps before asking AI to edit anything.
Can I use project instructions even if I do not code?
Yes. Project instructions can explain the goal, audience, protected areas, allowed changes, and review steps for WordPress pages, content workflows, calculators, and small website tools.
What should I put in an AGENTS.md file?
Include project overview, audience, allowed changes, protected areas, testing steps, style rules, and approval rules.
Does Claude Code read AGENTS.md?
Claude Code reads CLAUDE.md. If your project already uses AGENTS.md, you can create a CLAUDE.md file that imports or references AGENTS.md and then adds Claude-specific notes.
Can I use this with Codex?
Yes. Codex can use project instructions to understand what you want changed, what should stay protected, and how to verify the work.
Can I use this with Claude Code or Cursor?
Yes. The same ideas work across Claude Code, Cursor, Replit, and other AI coding tools, though each tool may handle instruction files differently.
Can AI tools break my website?
Yes, especially if they edit risky areas without review. That is why protected areas, testing steps, and approval rules matter.
What should I do before letting AI edit code?
Tell the AI the goal, allowed changes, protected areas, testing steps, and review rules. If possible, keep a backup or previous version.
