@mies @Claude @fiberplane @EffectTS_ It will be cool if you share your ast-grep rules about effect

We've been building with @Claude Code at @fiberplane since early days. Biggest takeaway: agents don't get better because you prompt them better. They get better when the codebase is explicit enough to constrain them. @EffectTS_ for typed errors + dependencies. Team favorite ast-grep to enforce patterns at commit time. Our own Drift to catch stale docs. We wrote up our entire setup, learnings and shares our rules here: fiberplane.com/blog/2026-04-1…

@EffectTS_ @aiDotEngineer I was sadly not there, is it recorded?

We're getting started! Effect workshop @aiDotEngineer

@ram_sutraye @Fried_rice No, no, it doesn't write itself, it's written by an AI bot

@Fried_rice A company that builds AI to write better code just leaked their entire codebase because of a missing .npmignore entry. The irony writes itself.

Claude code source code has been leaked via a map file in their npm registry! Code: …a8527898604c1bbb12468b1581d95e.r2.dev/src.zip

@nele_lea @EffectTS_ @_laurynas Thank you for posting a link to youtube. I hate having to listen to podcasts on X

My takeaway from the last stream: For self-driving codebases, more explicit code matters. Tools like @EffectTS_ can help by making code easier for agents to work with and for humans to reason about. Thanks @_laurynas for joining! youtube.com/watch?v=W3Om-e…

@MichaelArnaldi @kitlangton @EffectTS_ You mean otel libraries are fuked and it is better to just use sentry? I noticed that the quality of OTEL libraries is not the best, but I was not aware of how abandoned they were. The name indeed implies something big, but I think the "human effort" it gets is not on par.

@HellSatanS @kitlangton @EffectTS_ Not really also depending on otel is not ideal given the fucked up status of the libs (eg esm broken etc)

Hey. Sentry supports @EffectTS_ now. 😎 github.com/getsentry/sent…

@MichaelArnaldi @kitlangton @EffectTS_ Is Sentry not compatible with OTEL?

@HellSatanS @kitlangton @EffectTS_ It means you can use sentry to export telemetry, logs and metrics…

@danieljvdm @kitlangton @EffectTS_ Were you expecting it to support V4?

@kitlangton @EffectTS_ V3 😭

@SandroMaglione just read your latest newsletter about AI pace and coding speed, and I'm curious how you keep up with reviewing that much code. Everytime I start a swarm of agents the amount of code is so big it takes me almost as much time reviewing than writing that code

@Vishal_anton16 @MichaelArnaldi We're a startup of 2 people, and we are using effect with great success. Before that, it was a startup of 10 developers, and same, Effect was making us work better. What do you think makes it "overkill"? What has that to do with the company size?

@MichaelArnaldi Is there any popular oss repository using effect end to end. Just to understand the patterns I like effect. But for a startup with few engineers effect seems like overkill to me. Your thoughts on this? Do you believe there’s value in using effect for a 2 person company?

Effect is inevitable, especially in the AI era. And people are realising it, you’ll soon see prominent ecosystems integrating Effect. Won’t say more but this is already happening

@EffectTS_ Can you share the generators video mentioned at the end?

Effect Office Hours — riverside.fm/studio/kit-lan… x.com/i/broadcasts/1…

@DrizzleORM Fantastic, awesome, impressive. I have been waiting for it, great job

drizzle-orm@1.0.0-beta.15 is live with native Effect Schema support 🎉

@makisuo @EffectTS_ Glad to see I'm not alone thinking that explicit errors are the way to go. You either handle them or let them bubble up. Way better than shallowing them "for simplicity"

As promised here is my HIGHLY opinionated @EffectTS_ best practice guideline I have slowly building up over the last year of shipping effect code im production by hand and agent. Additional to this skill I would recommend pulling the whole effect repo locally Hope you guys enjoy!

@makisuo @audibledata @EffectTS_ Yeah, after a year of being the "recommend way" some of the effect maintainers "kind of prefer" doing layers explicitly. That seems to count as deprecation notice

@audibledata @EffectTS_ really? haven't seen anything about that

@BerrakasRetro después de una semana entera de intentos ni uno de vuestros cupones ha funcionado. Me pregunto si es que alguno funciona

@SandroMaglione @EffectTS_ Can you explain what it does?

Typical @EffectTS_ experience 👇 Use the API to implement your solution, then discover that somewhere there is already a module for that, and replace all with 1 line 🪄

@davidlbowman @SandroMaglione @EffectTS_ This is sadly true. But even if it were documented, it will be hard do find

@SandroMaglione @EffectTS_ and you know it's not on their main documentation page, it's somewhere in a GitHub repo, marked as available since version 1.0.0.

@emilwidlund @EffectTS_ It is also my lord and savior, long life @EffectTS_ !!

yes, @EffectTS_ is our lord and savior

@lgrammel Love to see Effect in the wild. Thank you, I love it. I was really looking for it

Latest AI SDK 6 beta supports the following validation libs: Zod, Valibot, Arktype, Effect Schema (Zod still needed for AI SDK-internal schemas)

@spion @SandroMaglione @EffectTS_ Yo can still use immer, leave the rest of us use whatever we want

@SandroMaglione @EffectTS_ in a world where we have immer, why do we need this?

@EffectTS_ v4 brings optics to TypeScript In other words, you don’t need to manually drill down an object to change one value 🙌
