coding agents struggle with large migrations.
slow, unreliable, costly. they need a lot of babysitting.
if you’re a platform/principal eng you’ve felt this pain 😅
so we gave them a new superpower
npx codemod ai 🎉
everything your AI coding agent needs for fast, reliable code migrations
free, open source, local-first, no login
and it gets better over time as models improve + community contributes to the registry
try it. break it. tell us what sucks
link + debarrel case study in replies 👇🏼
yeah, it’s awesome to see models getting smarter and using the right tool for the job.
i’m not sure what you mean by “3rd-party.” is jscodeshift a 3rd-party tool? is jssg?
to clarify, when you run:
npx codemod ai
instead of leaving your agent to pick a random codemod toolkit every time, it uses jssg, our open-source toolkit built specifically for large-scale code transformations. you can read more about how it differs from jscodeshift here:
https://t.co/dZebJeqo6q
we’re working hard to make jssg so good that agents choose it by default. until then, users only need to run one command. one and done. no need to think about codemod tooling again. (It comes with an auto-updater. It’s local. oss)
and if someone has already solved a problem before, like removing barrel files across a large codebase, your agent doesn’t have to waste time and tokens building a new codemod from scratch and rediscovering edge cases. it can reuse a battle-tested codemod from the registry and focus on getting the job done.
If you ever care to try our open-source codemod toolkit (adopted by React, Node.js, Nuxt, pnpm, webpack, react router, express, and many more) I would love to hear your feedback on it.

give codex the skills and tools it needs to build better codemods faster.
build, test, run, and publish codemods for any language, all from the cli.
every new codemod published to the registry makes the skill smarter and more useful for everyone running:

@poteto@stylexjs Lauren, run npx codemod ai once and moving forward cursor will build better codemods faster for u. And if the codemod already is built and published by others it just fetches that for u.
npx codemod ai
Give your agents all it needs to build better codemods faster. And if someone has already built a codemod for your use case, it automatically searches the registry and fetches that for you.
Would love to hear your feedback if you take it for a spin.

Q: How are job postings for software engineers rising rapidly despite AI agents automating coding?
A: Because there’s far more code to manage than ever before. We’re already seeing a 14x YoY increase in GitHub commits, and it’s accelerating.
AI has dramatically lowered the cost of writing code, so it’s now being used across far more businesses, applications, and use cases.
We’re at the beginning of a massive productivity boom driven by the proliferation of bespoke software throughout the entire economy.
Coding has been AI’s breakout use case this year. The fact that it’s increased demand for software engineers — rather than decreased it — should call into question the entire “AI will cause mass job loss” narrative.

@sama Two months free won't move teams off Claude Code. Lock-in isn't price. It's repo conventions, custom commands, internal evals, CI integration. Migration tooling beats trial length. Ship the codemod, not the discount.
awesome. have you heard about our codemod runtime jssg (JS ast-grep)? if you ever take it for a spin, would love to hear your feedback on it
https://t.co/dZebJeqVVY
you can just run
npx codemod ai
and your coding agents will get all the knowledge and tools it needs to build jssg codemods! just describe what you want from your agent...
🤖 Asking AI to refactor 200 files burns tokens, takes minutes, and sometimes hallucinates. A codemod does it reliably — for free. Nicolas Carlo shows how to use AI to write the codemods your team actually needs, live.
