Slack Code — Agentic coding is now a team sport. With Slack Code, your team and agents can plan, write, and review builds together. New agents in Slack: - Cedar - @coderabbitai - @datadoghq - @FactoryAI - @Lovable - @MistralAI - @NanoClaw_AI - @Replit - Rhythms - …↗

At Anthropic, Claude now writes 80% of our code. Engineers ship 8x more code per quarter. Side effect: Tests grew 10x. CI jobs up 25x in 6 months. Here's what helped us scale: claude.com/blog/agentic-c…↗

Introducing Gemini 3.8 Flash, another jump in Gemini's agentic + coding capabilities, and our 3rd updated Flash model in only 6 weeks... This model has been a ton of fun to work with, excited to see what you all think!↗

AI Engineering Skills Map: Software engineering fundamentals How have software engineering fundamentals changed with agentic coding? Even when you use a coding agent to write all your code, understanding software fundamentals is important for steering your agent to make the trad…↗

Hi, I’m John! I’m a L7 Senior Staff software engineer at Meta. My weird hobby is making AI Tech content on YouTube and Substack and I wanted to start sharing more here. In the past I’ve worked on Reels, Meta AI on Msgr and currently working on Threads. I also teach Agentic C…↗

We had a team of agents rebuild SQLite from its 835-page manual. It created a replica in Rust which passed 100% of a held-out test suite. Interestingly, cost varied 15x depending on which model mix we used.↗

🎙️ 🚨 Latest State of Agentic Coding w/ special guest @mariozechner (Flask) is out: - Vibe-checking Fable & GLM 5.2 - @mitsuhiko teaches us RL - How harnesses smooth out model jank - Loops, surviving AI fomo, and more Also on YT & Spotify ⬇️↗

For agentic coding, one can say: - Unless you need Terra Ultra perf, it's always better to use a Luna model with higher effort setting (same or better performance but cheaper). - Forget everything below Sol High, use Luna with higher effort settings here - Forget Sol Extra Hig…↗

Everyone's always talking about agentic coding harnesses: Claude Code, Codex, OpenCode, Pi... the list goes on. But what's the difference between all of them? What even Is a harness anyway? In this thread, we'll take a look under the hood. (1/5)🧵↗

The future of agentic coding and review is chatless Chat becomes a projection layer: logs, traces and context for o11y and audits The primary interface becomes dashboards that expose goals, progress, blockers, confidence and outcomes↗

TL;DR ELI5 of @trq212's new article: Claude isn't the bottleneck anymore. The stuff you forgot to tell it is. Your prompt is a map. The codebase is the actual road. Every pothole you didn't mention, Claude fills with its best guess, and the more work you hand it, the more it has…↗

A Field Guide to Fable: Finding Your Unknowns Working with Claude Fable 5 keeps re-teaching me an old lesson: the map is not the territory. The map, a representation of the work to be done, is my prompts and skills and context, it’s what I give Claude. The territory is where th…↗

Our latest economic research introduces a framework for tracking Claude Code as it scales. Who is using Claude Code, and what are they using it for? How is the value of tasks changing? And how much does domain expertise shape whether a session succeeds? …↗

We’re bringing new capabilities to GPT-Rosalind, a model series purpose-built for life sciences research at enterprise scale. It brings GPT-5.5’s agentic coding and tool use together with stronger intelligence for drug discovery, analysis, design, and experimental workflows. …↗

Some tips to help agents understand your codebase: 1. The source code either needs to be the source of truth, or have something legible as a path to the source. For example, if marketing site content is actually stored in a CMS, you need to either delete the CMS and move that co…↗

recommended reading. strongly recommended reading. i really like the pain avoidance angle. slots into my "paon/friction is when you learn" angle. when combined > cognitive debt. larsfaye.com/articles/agent…↗

For the past several months, our engineering team has been building a new agentic coding system designed around a simple idea: the self-driving codebase. These aren't just agents to write code on demand. They detect triggers, spin up secure sandboxes, gather dynamic context, ope…↗

AI-native software engineering teams operate very differently than traditional teams. The obvious difference is that AI-native teams use coding agents to build products much faster, but this leads to many other changes in how we operate. For example, some great engineers now play…↗

Why red/green tdd is good for agentic coding↗

I was recently ranked in the top 1% of engineers at small startups and #1 of all non-technical people on a engineering output platform called Weave. I've pushed half a million lines of (high quality) code to production since then and regularly ship features end-to-end in a day th…↗

Claude Code is an agentic coding tool that runs in your terminal, understands your codebase, and helps you complete tasks via natural language. It can execute routine work, explain complex code, and manage git workflows.↗

New blog post: "A sufficiently detailed spec is code" I wrote this because I was tired of people claiming that the future of agentic coding is thoughtful specification work. As I show in the post, the reality devolves into slop pseudocode haskellforall.com/2026/03/a-suff…↗

Agentic coding did change my brain in terms how I think about code - especially the terms. It *weaves* features in, it's all *shapes* of code. It *traces* through it. What other terms did you learn?↗
