  • AI is replacing jobs by helping people work faster, not by replacing humans directly, so learning to use AI tools (like Claude Coder, a tool that does tasks for companies) can help you stay ahead.
  • New "agentic" AI (AI that can act on its own to reach goals) is different from old automation because it can figure out and do steps to complete tasks without constant human input.
  • Tools like Claude Coder (a version of Claude chat that works with your local files) can help you organize and work with your files, like pictures, Excel sheets, and Word docs, making it more powerful than regular AI chat.
  • You can set goals for agentic AI, and it will keep working until the goal is met, like analyzing your YouTube videos and giving you insights.
2026-07-22
  • Using XML tags (simple markers like `<sales_records>`) in your requests to Claude API (a tool for building applications with AI models) helps organize content, making it easier for the AI to understand and process.
  • Providing examples in your prompts, especially when tasks are complex or ambiguous, helps Claude learn the pattern you want it to follow, improving the quality of its responses.
  • For tasks with varied inputs or complex outputs, use multi-shot prompting (providing multiple examples) to cover different scenarios, but keep the number of examples practical to avoid wasting space.
  • To create effective examples, use clear structure like `sample_input` and `ideal_output`, and explain why the example is a good one to help Claude understand the underlying reasoning.
2026-07-16
  • Claude (an AI assistant) can automate boring tasks, like sorting emails into categories (leads, urgent, etc.) and drafting responses, saving you 5-10 hours weekly.
  • For leads, Claude can research companies, draft replies, and even schedule meetings using your calendar, streamlining your sales process.
  • After client calls, Claude can generate branded PDF proposals with scope, pricing, and signatures, saving time on manual proposal creation.
  • This setup can be adapted to various jobs, especially those involving sales, marketing, or regular research tasks.
2026-07-13
  • Cloud Code (a tool for AI users) isn't just for developers; it helps non-technical users get reliable AI results by working with files and folders on your computer.
  • Use Cloud Code (not regular Claude, a chat-based AI) when you need to create, reuse, or improve files, like sales pages or customer research, that stick around in your business.
  • To start using Cloud Code, download the free app VS Code (from Microsoft), add the Cloud Code extension, and give it access to a folder on your computer to use as your workspace.
  • Once set up, you can tell Cloud Code to create new folders and files, and watch it make live changes in those files as it works.
2026-07-04
  • Claude (an AI tool by Anthropic) is helping non-coders build real businesses, like Vulcan, which won a Virginia state contract for government software.
  • Claude Code (a feature of Claude) builds full apps, websites, or automates tasks in minutes, just by describing what you want in plain English.
  • Claude is "agentic" (it takes action on its own), works in parallel (multiple tasks at once), and remembers things, making it a powerful tool for businesses and jobs.
  • Over half of the startups in Y Combinator's (a famous startup accelerator) newest batch are building with Claude, showing its growing popularity and effectiveness.
2026-06-28
  • Claude (an AI assistant) is designed to make users feel productive, not necessarily make money, which can limit earnings by reducing output quality and speed.
  • Claude tends to agree with users too much, a trait researchers call "sycophant" or "yes man," which can lead to poor decisions; a tool called "roast" helps combat this by challenging ideas.
  • The "roast" tool creates a council of personas to stress test ideas, including a contrarian, expansionist, first principles thinker, deep researcher, buyer, and judge, providing a verdict and cheap test suggestions.
  • These upgrades aim to improve Claude's usefulness for business, such as building apps, running agencies, or AI consulting, by enhancing output quality and speed.
2026-06-25
  • Claude (an AI assistant) has three main modes: Chat (quick answers), Co-work (file access), and Code (full access, best for building things).
  • Opus 4.8 is Claude's most capable model, Sonnet 4.6 for daily tasks, and 4.5 for fast, simple work.
  • Connect Claude to tools like Gmail, Google Drive, or Firecrawl (a web data grabber) to boost productivity.
  • Use "sub agents" in Claude to multitask, getting 5-10 times more output in the same time.
2026-06-19
  • AI coding assistants (tools that help write and plan code) can handle large amounts of information, but they can still make mistakes, like sending emails to the wrong people.
  • You need to carefully plan and verify the work of AI coding assistants, as they might still find ways to do things you didn't explicitly allow.
  • Claude Code (a popular AI coding assistant) can be used as a "second brain" to help run your business, not just for coding.
  • AI tools and their uses are changing quickly, so it's important to stay updated and learn how to use them effectively.
2026-06-16
  • A new tool called SkillSmith (a plugin for Claude, an AI assistant) lets you build AI agents (automated workers that can perform tasks) in minutes using simple text files, not complex code.
  • Claude skills (the new way to build agents) use plain text files to define triggers, context, frameworks, tasks, and templates, making them easier to create and understand.
  • SkillSmith offers four main functions: turning ideas into specs, building skills, distilling long-form content into frameworks, and auditing existing skills.
  • Appify (a marketplace for AI actors) and its MCP (a bridge between Claude and other software) help find and use the right AI actors for your workflows.
2026-06-13
  • AI coding agents (AI tools that can write and fix code) can help fix bugs and verify their own work, but using them too much can lead to exhaustion and burnout.
  • AI agents can scale infinitely and work continuously, but human attention and judgment are still limited and can degrade under heavy use.
  • To maintain balance, consider using "signal layers" (prioritizing important tasks), voice-first coding (coding using voice commands), and remote control (controlling AI tools remotely).
  • Small changes in how you work and store information can enable AI agents to find patterns and improve your system without constant human input.
2026-06-07
  • Anthropic (the company behind Claude, an AI assistant) shared key lessons from building Claude skills (folders of instructions and resources that help Claude do tasks better), emphasizing that skills are more than just simple text files.
  • They categorized skills into nine types, like "library and API references" (tools for developers) and "business automation" (workflow helpers), advising to keep skills focused on one category for best results.
  • Anthropic recommends including a "gotchas" section in skills, highlighting common mistakes to help Claude avoid errors and improve performance over time.
  • They suggest using the file system for "progressive disclosure," organizing skill content in a way that reveals information step by step, making it easier for Claude to learn and use skills effectively.
2026-06-04
  • Claude Code (an AI tool from the company Anthropic that writes and edits code for you) can now build professional-looking websites that clients pay for.
  • A new CMS (content management system, a dashboard where you or clients can edit a website without touching code) lets anyone update text, prices, or pages by just chatting to AI.
  • The CMS also includes built-in SEO (settings that help your site show up in Google searches) and shows you a score to improve your ranking.
  • Clients can edit their own site without needing your login or breaking anything, so you can hand off the site and focus on other work.
2026-06-03
  • Skill Creator automatically builds reusable skills (tools Claude learns to use repeatedly) from plain English descriptions, no manual code writing required.
  • Superpowers makes Claude plan first, write tests (code checks that verify everything works), and self-review twice—catching mistakes before clients see them.
  • Businesses pay most for simple, boring skills that save time, money, or prevent errors—not flashy ones made just for social media videos.

Key points

What it is

  • Prompt engineering is writing clear, specific instructions to get better results from Claude, an AI assistant (like a brilliant contractor with many skills).
  • It's not about making Claude smarter, but making it more focused by removing unnecessary information.
  • The goal is to create precise prompts that guide Claude to produce useful, focused outputs.

How to use it

  • Start every conversation by stating your intent (what you want), constraints (what Claude shouldn't do), acceptance criteria (how you'll know it worked), and file locations (where to look).
  • Use plan mode to explore problems before implementing solutions, and iterate conversationally if the first attempt isn't right.
  • Create a `Claude.md` file to shape interactions, listing your skills, hooks (scripts that run on events), and MCP (a tool for connecting apps) connections.

Watch out for

  • Avoid vague prompts, as they lead to vague results. Be specific and precise in your instructions.
  • Don't leave broken attempts in the conversation, as they can confuse future responses. Start a fresh session after a failure.
  • Don't rush. Plan the entire solution first and write tests before writing any code to prevent sloppy work.

Lesson 1: What is Prompt Engineering for Claude and why it matters

Prompt engineering for Claude is the practice of carefully writing instructions (prompts) to get useful, focused outputs from the AI. It matters because “the quality of the clearness of your prompt and the context that you feed it is directly tied to the quality of output.” A vague prompt produces vague results — “garbage in, garbage out.”

Think of Claude as a brilliant contractor you just hired. It has many skills but has never seen your project before. The more precisely you explain what you want, the better the result. For example, using a capability uplift skill (a prompt that teaches Claude to do something better, like design websites) turns a generic-looking site into a polished one. Without it, you might get “AI slop” — mediocre output.

Prompt engineering is not about making Claude smarter; Claude is already very intelligent. The goal is to make it more focused by removing noise. One key tactic: “don’t use defaults” — add your own spin instead of accepting generic outputs.

However, beginners should know that prompting alone isn’t the most valuable long-term skill. “If you want to make real money with AI in 2026, prompting isn’t the skill. Systems are.” Individual prompts are manual, have no memory, and produce inconsistent results. A system (a repeatable workflow) creates leverage so AI works for you, not the other way around.

Master both: craft precise prompts for immediate results, then build those prompts into systemized workflows for scale.

Lesson 2: How to use Prompt Engineering for Claude: step-by-step

Prompt engineering for Claude means writing clear, specific instructions to get better results. The single highest leverage move is giving Claude something to verify against — tests, expected output, or screenshots it can check without you in the loop. Pair this with grounded reading: never let Claude speculate about code it hasn't opened.

Start every conversation by stating four things upfront: intent (what you actually want), constraints (what Claude shouldn't do), acceptance criteria (how you'll know it worked), and file locations (where to look). This makes your first message carry weight and prevents expensive back-and-forth. For example, instead of a vague "Add this feature," say: "Add a search bar to `index.js` that filters results by category. Don't change the CSS. Verify it works by checking that typing 'react' returns only React-related items."

Delegate, don't dictate. Give Claude context and direction, then trust it to figure out details. If the first attempt isn't right, iterate conversationally — you don't need to start over. Use plan mode to explore before implementing: ask Claude to analyze the problem first, then write the code.

Create a `Claude.md` file (a force multiplier that shapes every interaction) and keep it short, opinionated, and updated regularly. List your skills, hooks (scripts that run on events), and MCP connections. Each bullet should be under 15 words with no explanations. Over time, let your `Claude.md` learn from failures so future sessions start fresh without old baggage.

Lesson 3: Best practices and pitfalls

Here are the biggest mistakes and best practices for prompt engineering with Claude Code.

The number one pitfall is rushing. Many beginners give a vague prompt like "Add this," then react to whatever Claude spits out. This leads to sloppy code. A best practice is to force Claude to act like a senior developer: step back, plan the entire solution first, and write tests before writing any code. This prevents the common failure mode of rushed, surface-level work.

Another critical mistake is leaving broken attempts in the conversation. When Claude does something wrong, many users simply say "That didn't work, try this instead." That failed code and wrong approach stay in the context (the conversation memory), confusing future responses. Always start a fresh session after a failure, so Claude learns from a clean slate.

Use skills (pre-packaged prompt templates) to improve quality. For example, the "Superpowers" skill forces Claude to work in an isolated environment, brainstorm, write tests, and review its own work in two stages — once for matching the spec and once for code quality. You can also install tools that inject current documentation into the conversation before Claude writes any code, giving it up-to-date information for better results.

Finally, remember that prompt engineering is software engineering. Be specific, plan first, and clear out mistakes. These practices will make Claude noticeably better at its job.
