Hello

[Ruben Hassid @rubenhassid]

Don't upgrade to the $100 Claude plan (yet).

These 21 hacks make the $20/month plan enough:

1. You upload PDFs raw. One page = 3,000 tokens.
Fix: Paste the text into a Google doc. Download as .md format, then turn it into a Skill.

2. You build files inside Cowork too early.
Fix: Plan in Chat first. Move to Cowork only when you know exactly what you want.

3. You write 500-word prompts that reload.
Fix: Write 29 words instead: "I want to [task] to [goal]. Ask me questions using AskUserQuestion."

4. You say "redo the whole thing" to fix section 3.
Fix: "Only redo section 3. Keep everything else. No commentary. Just the output."

5. You send 3 separate messages for 3 tasks.
Fix: One message, three tasks. "Summarize this, list the points, suggest a headline."

6. You type "No, I meant," stacking on the history.
Fix: Click 'Edit' on your original message. Fix it. Regenerate.

7. You rewrite prompts from scratch every time.
Fix: Keep a prompt library. Same structure, swap the variable.

8. You use Opus for a simple grammar check.
Fix: Sonnet for quick tasks. Save Opus (High) or Fable (High) for the real work.

9. Your about-me file is 22,000 words (too long).
Fix: Trim to under 2,000 words. End sessions with "Write a session-notes .md."
Paste my .md file prompt: https://t.co/LyV7fegv4c

10. You never restart & keep stacking long chats.
Fix: When Cowork goes sideways, click "Restart the conversation from here" on an earlier message.

11. You never summarize before things get long.
Fix: Every 15-20 messages → summarize, copy the brief, start a fresh session.

12. You use Projects for recurring files.
Fix: Use Projects. Upload once. Every chat inside references it without re-burning tokens.

13. You dump 50 files into Cowork "just in case."
Fix: Only include what this task needs. Zero folders for quick tasks like email drafts.

14. You keep 3 topics in 1 chat. Claude re-reads all.
Fix: New topic = new chat. Always. Dead context is dead tokens.

15. You leave search & connectors on by default.
Fix: Default everything off. Turn features on per task, not per account.

16. You manually run the same report every week.
Fix: Use /schedule. "Every Monday at 7am, create my weekly briefing."

17. You let Claude Code explore your whole repo.
Fix: Be specific. "Build a bar chart from this CSV. Save as chart .png."

18. Skip Personal Preferences & waste setup.
Fix: The minimum possible. Don’t give any info. Turn off Memory.

19. You type lazy prompts like "make it better."
Fix: Speak your prompts with wispr .ai. Richer context in one shot.

20. You burn your whole limit in one morning.
Fix: Claude runs on a rolling 5-hour window. Split it.

21. You use Claude for things it can't do.
Fix: Know your tools. Images → Gemini.
Real-time search → Grok.

3. Go to the Notion link.
5. Copy-paste prompts, too.

Google Brain founder, Andrew Ng:

"100% of my tasks are done by ai agents, self-improving loops are next.

Give it 3-6 months and prompting is gone."

32 minutes of clear explanation on building loops from scratch.

Worth more than any $500 agentic course.

Watch it, then read the full guide below.

[Kid Pak @kidpakerot]

last month, I did over 300 million views running iPhone farms for other people's startups.

the catch: the only people who can pull that off are agencies with racks of phones and a team babysitting them.

so I built Warmr to hand that same machine to everyone else.

how I got here:

> ran iphone farms for startups, quietly cleared 300M+ views in a month
> watched brand new accounts die at 300 views while aged ones hit millions
> realized it was never the content, it was the account warmup
> automated that warmup on real iphones, no emulators, no bots
> made it so that one mac ended up running a whole rack of phones on its own
> founders kept asking how I did it, so I turned it into an app
> now a solo founder with one iphone runs what an agency runs

If you're interested, comment "Warmr" and I'll send you a free invite

this is f*cking dangerous

someone just revealed how to run a 10-person company with zero employees using one Claude Project

Anthropic's CEO bet on a $1B one-person company by the end of 2026.

less than 6 months left. solo founders are already past several hundred million.

here is how:

1) Create a Claude Project and add your business files
2) Connect 10 MCP agents to it for research, leads etc
3) You sit in the decision seat. the agents run the execution layer.

you don't need more employees. you need MCP agents that know the business.

save and bookmark it no matter what

then read the full article below on how to build your first company with AI without any employee: ↓

[Rahul @sairahul1]

Jensen Huang, CEO of Nvidia:

"Every engineer is going to have and manage hundreds of agents."

The most valuable engineering skill of 2026 is not taught in any university.

No CS program teaches harness engineering.
No bootcamp teaches agent memory architecture.
No degree prepares you to build systems that survive production.

One builder mapped the entire thing out — free, step by step, no degree required.

This is the roadmap ↓

Bookmark this for the weekend.

Introducing Apple Notes ads in Claude

We made a skill /goose-video that teaches Claude to one-shot Apple Notes ads like these.

Apple Notes ads are doing incredibly well on Meta and TikTok - because they're authentic, easy to understand and drive curiosity.

This skill teaches Claude to makes ads like these using only HTML - no video generation models – so it's very reliable and cheap to make an ad.

Just install the skill and prompt Claude to make as many variants as you'd like to test.

Comment Goose and I'll DM you a link to install the skill.

(must be following, or I can't DM)

most people spend hours describing what they want to Claude Code

this guy just browsed a catalog of thousands of animated UI components, found one he liked, and hit "copy prompt"

that's it. the prompt goes into Claude Code and it builds it.

> 21st(.)dev - a library of community-made components built for React, Next.js, Tailwind
> every component has a ready-made prompt attached
> you pick the effect, copy, paste, done

no describing animations from scratch. no explaining what "smooth scroll" or "hover glow" means. someone already figured out the exact prompt that produces it.

gap between people who know this exists and people who don't is measured in hours per project

full walkthrough in the article below

[Hello @userjohn27]

@bcherny Awesome, thank you for the update! Also, anyway I can get some builder swag from you? I like the black claude cap you give out and the plushie 😅

[Boris Cherny @bcherny]

New in Claude Code: /checkup

Run /checkup to:

1. Clean up unused skills/MCPs/plugins and save context
2. Dedup your local CLAUDE.md against the checked in CLAUDE.md
3. Break up root CLAUDE.md into nested CLAUDE.md's + skills
4. Turn off slow hooks
5. Update your Claude Code to the latest version
6. Enable auto mode by default
7. Pre-approve frequently denied read-only commands

.. And a few other goodies.

/checkup confirms with you before making any changes. Enjoy!

Introducing iMessage video ads in Claude

We taught Claude to make iMessage video ads in one shot with a single skill.

These iMessage ads are absolutely killing it on Meta right now.

The skill teaches Claude to make a full video ad in one shot with iPhone frame, SFX, music, and end card.

And it's just HTML. It doesn't use any video generation models, so it's cheap!

Comment Goose below and I'll send you the skill.

[Hello @userjohn27]

@karenxcheng @cursor_ai Thats pretty cool

[Karen X. Cheng @karenxcheng]

i hooked up a rotary phone from the 1920s to an AI agent, that replies on a mechanical display

it’s like a dumbphone without distracting notifications

here’s how i built this w/ @cursor_ai

[Kikirkikirkikir @kikirkikirkikir]

@gagarot200 Certification is open to organizations in the Claude Partner Network." The $125 fee is only waived for Partner Network members not for the general public. Whoever tweeted this as "free for everyone" is spreading misleading info; it's a partner-only discount,not a public giveaway.

Fable turned my remarkable into Tom Riddle's diary from Harry Potter.

My prompts fade, a LLM respond.

Magical!
