IBM's Martin Keen explains AI's most-repeated myths better than any explainer thread on X.
In 15 minutes, he walks developers through what context windows actually do, whether models really reason, and where AI reliability breaks down.
Here's what it covers:
➔ What context windows really do (and don't)
➔ Whether AI models actually reason
➔ Where machine learning ends and AI begins
➔ What "AI agents" mean in practice
➔ Why AI still hallucinates

You don't need a higher Claude plan. You need 7 better habits.
The shortlist:
1. Never run a chat past 20 messages → summary, new chat, paste, continue
2. Tell Claude how long to respond → "answer in 2 sentences"
3. Put company info and brand docs into Projects → not every chat
4. Add "Don't ask questions. Make your best assumption" → fewer turns, fewer tokens
5. Edit and regenerate → instead of sending follow-up fixes
6. Set up Instructions to Claude in Settings → your role, tone, audience, format
7. If the first output missed, change the prompt → don't gamble tokens on luck
Cut your usage by ~80% without changing models.

Most people install random Claude skills and never use half of them.
Better move: start with these 5. They cover the biggest gaps:
1. Grill-Me → interview before execution
2. Humanizer → clean tone, no AI tells
3. Fact-Checker → flags claims it can't verify
4. MCP-Builder → custom MCP for any tool
5. Prompt-Master → rewrites brain-dumps into prompts

I booked a $1,190 flight for $159.
ChatGPT replaced Google Flights, Booking, and Skyscanner for me. Here are the 7 prompts I now use before any trip:
1. Smart Flight Finder. Cheapest flights using flexible dates, alternate airports, and hidden-city routes.
2. Error Fare Monitor. Recent mistake fares and flash sales from your region.
3. Budget-Friendly Stay Locator. 3 hotels or Airbnbs under your nightly cap, near the good areas.
4. Free Fun Finder. 5 free or super cheap things to do at your destination.
5. Cheap Eats Expert. 3 local spots under your price limit that locals actually love.
6. Best Time to Book Trick. The cheapest date range based on current pricing trends.
7. Trip Budget Calculator. Full trip cost estimate plus one bonus saving tip.

How to turn ChatGPT into a lawyer, a recruiter, a debt planner, and a travel agent.
10 prompts that do the heavy lifting. Copy, paste, and watch:
✦ Lawyer in your pocket
"I need help with a legal situation: [selling a car, signing a lease, disputing a charge, writing a freelance contract, understanding a letter I received]. Walk me through my rights, write the document or response I need, and flag anything that could hurt me. Explain it all in plain English."
✦ Price scanner
"[upload photo of product] Find me a cheaper version of this exact product. Same quality, same materials, different brand. Search the web and show me where to buy it, the price difference, and whether the cheaper version has any real trade-offs."
✦ Ingredient scanner
"[upload photo of ingredient label] Flag every ingredient linked to health concerns. Tell me what each one actually does, how serious the risk is, and suggest a cleaner alternative product I can buy instead. Write it so someone with no science background understands."
✦ Competitor analyzer
"Here's my competitor's website: [paste URL]. Search the web and break down their entire strategy. What they sell, how they position it, their pricing, what's working, their weak spots, and how I could beat them. Give me the full breakdown like a $5,000 consultant would."
✦ Item appraiser
"[upload photo of your item] Tell me what this is worth right now. Search current resale prices, tell me the best platform to sell it on, and write me the listing title and description that gets the highest price. If it's worth more than I think, tell me why."
✦ Debt payoff planner
"Here are my debts: [list each one with the balance, interest rate, and minimum payment]. Build me the fastest payoff plan. Show me the exact order to attack them, how much extra to put toward each one, the total interest I'll save, and the exact month I'll be completely debt-free."
✦ Resume builder
"[upload your resume and paste the job description] Act as the recruiter hiring for this role. Score my resume out of 100, list the keywords it's missing, name the 3 things that would make you reject it in 10 seconds, then rewrite the whole thing tailored to this exact job. Be brutal."
✦ Travel planner
"Plan me a [number of days] trip to [destination] for [number of people] on a [budget]. Search for the cheapest flights, best-rated hotels in my price range, a day-by-day itinerary with real places to eat and visit, and every way to save money a tourist wouldn't know. Make it a trip I'd book tonight."
✦ Handoff prompt
"This chat is too long. Write a complete handoff document for a new chat covering: the goal, all the context needed to understand it cold, every decision we made and why, what's done, what's left in order, and the exact next step. Make it detailed enough that a fresh AI with zero memory picks up exactly where we left off."
✦ Recipe stealer
"[upload photo of a dish] Every ingredient, the exact quantities, the cooking technique, and how to make it at home so it tastes like the original. If there's a reason the restaurant version tastes better than homemade, tell me that secret too."

I wish I had this 5-day Claude roadmap when I started.
Each day adds one layer. By Day 5, Claude works for you, not the other way around.
Day 1: install Claude and set up your 4 folders
Day 2: feed Claude your context (about-me.md and ai-style.md)
Day 3: put Claude on real work, not chat
Day 4: connect your tools with MCP (Gmail, Drive, Slack, Notion)
Day 5: unlock Claude Code for tasks that run themselves
