Boris Cherny runs Claude Code at Anthropic. His line should stop you mid-scroll: "I don't prompt Claude anymore. I have loops running that prompt Claude and figure out what to do. My job is to write loops." The skill moved. From writing prompts to building the loop around them.... A loop that works has three things. Drop one and it burns money in circles. 1. A finish line it can prove. Tests pass or they fail. "Looks done" is not a finish line. 2. A checker that did not write the code. A model grading itself always says yes. 3. Brakes set before you start. A step limit. A money ceiling. A stop condition. That is the whole game. The loop does the work. You design the cage it runs in. Full breakdown below.show more

$Boris Cherny, head of Claude Code at Anthropic: "I don't prompt Claude anymore. I have loops that are running; they are the ones prompting Claude and figuring out what to do. My job is to write loops." He's right. Karpathy and Steinberger arrived at the same conclusion from different angles. The skill has a new name. Loop engineering. Cherny's token bill is zero. He works at Anthropic. Steinberger burned $1.3 million in OpenAI credits in 30 days. He works at OpenAI. Loops are the right architecture. But the people evangelizing them aren't the ones paying. I wrote a breakdown of five plays that land most of what a loop gives you at a fraction of the cost, plus the one case where a loop is worth paying for.$

Creator and head of Claude Code, Anthropic: "I don't prompt Claude anymore. I have loops running that prompt Claude and decide what to do. My job is to write loops." He hasn't hand-written a line of code since November. 100% is Claude Code now. Still ships 10 to 30 pull requests a day. He breaks down his actual workflow in the 1h28m podcast. Loops writing 100% of the code. Engineer leveling up, or automated out?

Boris Cherny (Claude Code creator): "I don't prompt Claude anymore... my job is to write loops." In his latest interview, he breaks down the setup step by step. He runs /loops + a dynamic workflow + a couple hundred agents that read his GitHub, Slack, and Twitter and decide what to build next. His only job now is writing the loops that orchestrate them. That's a multi-agent workflow. I broke down how to build your own below ↓

The creator of Claude Code deleted his IDE in November 2024. In the last 30 days, 100% of his contributions were written by Claude Code. 259 PRs. His job is not prompting anymore. His job is writing loops that prompt Claude for him. Here is what that progression actually looks like: → stage 1: write code by hand with autocomplete → stage 2: run 5-10 claude sessions in parallel, prompt each one yourself → stage 3: write loops that prompt claude — you become the author, the model becomes a subroutine → the ralph loop (2025): bash one-liner, fixed anchor files, built a programming language for $297 → the 2026 loop: loops supervising loops, scheduling on infrastructure time, git-backed durable state → five building blocks: automations, durable state, validator split, loop orchestration, crash recovery Most developers are still in stage 2, prompting sessions by hand. The ones at stage 3 are writing the loops that do the prompting for them. Read this article to be ahead of the curve! Follow NeilXbt for more AI engineering intelligence that shows you exactly where the leverage moved and what building at that level actually looks like.

Boris Cherny, the creator of Claude Code at Anthropic, just explained why he stopped prompting Claude entirely in this talk he breaks down exactly how the future is teams of agents, not better prompts: - the 14% you lose to CLAUDE.md before typing a word - the features that change how Claude thinks before you type a word - the features most Claude users don't know exist - why typing prompts one at a time is already the slow lane Boris Cherny: "Now I don’t prompt Claude anymore - I have loops that are running. My job is to write loops." if you've been using Claude for more than a month and never left the chat window, you have at least 23 untouched features. probably 25 instead of another show tonight, watch this make sure to bookmark it before it gets lost in your feed my breakdown of all 25 features is below

Old way of using Claude Code: Prompt → wait → review → prompt → wait → review → repeat 20 times. You are the loop. You are the condition check. You are the reason it keeps going. New way: /goal all tests pass and lint is clean Claude works. You do something else. You come back to a result. Here's exactly how to set it up — and how to write conditions that actually work ↓

Borris Cherny the creator of Claude Code doesn't write code. He doesn't even talk to Claude. He runs one Claude that prompts the rest. He drops it like a throwaway, but that's the whole game now. You stop being the worker and become the one who runs them. ↓read this today to master multi-agent system

Boris Cherny: "My job is to write loops." 5-day version you can copy for Claude Code Day 1: repo memory - write CLAUDE.md - include stack, test commands, code style, release rules, gotchas - add .claude/settings.json with the shell commands Claude can run Day 2: verification skill - pick 1 flow Claude keeps breaking - put the browser/API test in .claude/skills/ /scripts/ - make it return: pass/fail, failing step, screenshot/log path Day 3: commands Add these files: .claude/commands/babysit.md - checks your PRs - reads CI - handles obvious review nits - surfaces design questions .claude/commands/triage-issues.md - labels new issues - dedupes against existing ones - assigns owners .claude/commands/deploy-watch.md - checks the live app - reports regressions - avoids touching production Day 4: loops > /loop 5m /babysit > /loop 15m /triage-issues > /loop 5m /deploy-watch Day 5: overnight work - schedule /morning-report - schedule /deep-audit - write results to .claude/inbox/ - let your morning loop read from that folder The rule: every code-writing loop gets a separate verifier. Builder makes the change. Verifier runs the real app. You read the diff. Skip that and you wake up to 14 broken PRs with very confident summaries.

boris cherny shipped 259 PRs in 30 days and typed none of them. claude code wrote every line. peter steinberger said the same idea this week and it hit 2.2M views. one built claude code at anthropic. one built openclaw and joined openai. opposite labs, one conclusion: stop prompting agents, write the loops that prompt them. the replies are still arguing about what a loop even looks like in practice. i went looking for the built version. it's a multi-agent workspace manager called gas town: a coordinator agent runs 20-30 workers and a merge queue gates every change before it hits main. the philosophy fit in two tweets. the implementation has 15k stars.

📁 Boris Cherny, engineer at Anthropic, says 100% of his code is written by Claude. He ships 10 to 30 pull requests a day and has not edited a single line by hand in months. Claude writes it. Claude reviews it. Humans are still in the loop, but they are no longer the ones typing.

Dario Amodei just told software engineers exactly how long they have. Six to twelve months. Amodei: “I have engineers within Anthropic who say I don’t write any code anymore. I just let the model write the code, I edit it, I do the things around it.” The people building the most powerful AI in history have already stopped writing code. That is not a forecast. That is the current working condition inside the lab closest to the frontier. Amodei: “We might be six to 12 months away from when the model is doing most, maybe all, of what SWEs do end-to-end.” The tech industry spent a decade making software engineers its highest-paid, most protected class. That era has a last day now. When a model can execute an entire software build end-to-end, the ability to write syntax stops being a skill. It becomes a credential for a job that no longer exists. Amodei: “And then it’s a question of how fast does that loop close.” That is the sentence everyone skipped. The code was never the hard part. The hard part was everything around it. The model just learned everything around it. Writing the code is already nearly gone. Testing is next. Deployment is next. When all three collapse into a single autonomous execution loop, the machine no longer needs a human in the chain at all. The corporation or sovereign state that closes that loop first does not gain a competitive advantage. It gains a category of speed that biological engineers cannot match, track, or reverse. That is not disruption. That is replacement at a systems level. Amodei is not describing a future disruption. He is describing the current state of his own building. The loop is already closing. The only question is whether you are inside it or outside it when it seals.

If agents led to an explosion in AI usage (and cost), wait until corporate America discovers “loops" Agents prompting agents Last month I asked Claude Code's cat and Boris Cherny what feature they’d be proudest of in 10 years. Both said loops. "It's an agent that prompts Claude. I don't write the prompt anymore... Claude writes the prompt, and now I'm talking to that new Claude."
