Do you remember when you joined X? I do! #MyXAnniversary --- I didn't until X told me lol, back then it was the lil blue bird instead of an X off course :)

1.Saturday morning, coffee in hand, revising chapter 3 of my science fiction novel while CI runs. Any devs here with too many projects for one lifetime?

Most AI coding agents fail for a boring reason. They get fed bad context. I spent 4 weeks reading 200+ sources on this, built a Claude Code skill that fixes it, and validated it on three production repos. > Shipping today: nv:context skills.nichevlabs.com

i hate this @learnframer guy... selling a silly course for $847. so here's what i'm doing: i've purchased 5 copies of the course, and now giving them away for FREE! send comment "UNDERCOVER" to enter the giveaway. (announcing tomorrow)

Tried magnifying with html-in-canvas API Wow

@heyshipz Hey there!

NO account should be under 1k !! say hi and WE follow YOU

@shvshydv Awesome, yep let's connect

@johnnichev Hey John! Just checked out Selectools. Let's connect, I'm building in public too!

Why I Built Selectools (and What I Learned Along the Way) medium.com/p/why-i-built-…

SELECTOOLS: Multi-agent graphs, tool calling, RAG, 50 evaluators, PII redaction. All in one. medium.com/p/selectools-m…

@ionleu selectools.dev not a startup but a tool for engineers that work with AI agents! Better than langchain in many aspects, check this out :)

drop ur startup link

@trikcode I just launched a langchain/crewai free open source competitor called selectools! selectools.dev is easy to use and has 50 evals, guardrails including PII redaction, cost tracking and visual builder :)

There’s a whole group of people right now: - exploring AI tools, - shipping ideas, - learning in public. If that’s you...say hi to each other & connect

@trikcode yo

html-in-canvas API is shattering my expectations

Building selectools taught me context engineering the hard way. I turned what I learned into a separate Claude Code skill: nv:context. 3-minute install. Works with Claude Code, Cursor, Copilot, Aider. Validated on selectools + 2 other production repos. Separate Show HN this afternoon. skills.nichevlabs.com

Works with OpenAI, Anthropic, Gemini, Ollama. Python 3.9+. Apache-2.0. pip install selectools GitHub: github.com/johnnichev/sel… Docs: selectools.dev/QUICKSTART/ Changelog: github.com/johnnichev/sel… Built by @NichevLabs. Feedback welcome.

LangGraph's interrupt() mechanism re-executes the entire node body on resume. By-design behavior from its checkpoint-replay model. You have to make pre-interrupt work idempotent, place it after interrupt(), or split nodes. It's a leaky abstraction. selectools handles this differently. Thread:
