Developer tools are no longer built only for humans at a terminal. They are also used, tested, broken, and improved by AI agents.

In this session, I will share how to create tools where you can have agent-reported issues, automated reviews, refactors, and release workflows to the point...

What makes an agent skill reliable, performant, and maintainable? We will explore a robust approach to skill design, starting with foundational best practices, moving into automated skill generation, and validation. The second half of the talk focuses on the critical role of evaluation, demonstra...

Talking about using heap dumps to find and fix Node.js memory and CPU problems. Starting with a horror story of server crashes and memory leaks in Node.js environment. Exploring why memory leaks occur in JavaScript and how garbage collection works in programming languages. Memory leaks can occur in garbage collected environments. Understanding how garbage collection works in JavaScript and general programming languages. Exploring the mark and sweep phases of garbage collection to identify and reclaim unreachable objects. The garbage collection process involves two phases: mark and sweep. Objects not reachable from roots are marked for removal. The issue arises when objects can still be reached, causing memory leaks like with unbound caches. Memory leaks can occur due to global references or unclosed hooks causing objects to remain in memory, leading to potential memory overflow. Memory usage fluctuates due to garbage collection cycles, which prevent memory leaks by releasing unused memory. A memory leak leads to increasing memory and CPU usage, potentially causing system unresponsiveness. Pinpointing memory leaks is challenging as they affect the entire application, often appearing in production environments. Heap and memory dumps help analyze memory issues, generated in multiple ways like DevTools and command line. Exploring memory usage through Node.js application launch, debug mode, and heap snapshot analysis in Chrome DevTools. Exploring memory snapshots and pinpointing memory leaks by creating diffs between snapshots to identify leaked objects and their references for easy fixes. Exploring different methods for generating memory snapshots, including CLI flags, experimental node flags, and API usage, to efficiently identify memory leaks and manage heap dumps in Node.js environments. Discussing security considerations, challenges in memory leak detection, utilizing heap dumps for resolution, and emphasizing the importance of data security and verification in fixing memory leaks.

On my YouTube channel AI Coding Daily, I've published 100+ videos comparing different models for coding: Opus vs GPT, Kimi vs GLM, New vs Older versions, Effort Medium vs High, etc. Now I see clear patterns for evaluating models and deciding which one to choose for specific tasks and projects.

When you need to apply the same change across hundreds of repositories, manual PRs don't scale and traditional codemods can't handle the unexpected. In this talk, I'll walk through the engineering journey from building a single-repo migration skill to deploying a fleet of parallel AI agents that...

This talk dives into how developers can build structured, repeatable coding workflows using Claude Code's ecosystem: Skills, Subagents, settings, Hooks, and MCP servers. I'll walk through the architecture behind Claude Code Templates, an open-source project with 120K+ npm downloads and 23K+ GitHu...

Introduction to ARIA, its meaning, and the complexities of accessibility in web development. Exploring the importance of proper ARIA usage for web accessibility and the pitfalls of incorrect ARIA implementation. Exploring the importance of landmark roles in web development and their benefits for screen reader users. Discussing the impact of AI-enabled assistive technologies on ARIA and emphasizing the importance of using semantic HTML. Discussing the importance of visually hidden text in the correct DOM order and the challenges of accessibility for chart-heavy pages. Discussing the importance of testing with users with disabilities, upcoming accessibility requirements for web pages, and considerations for making AI more accessible.

Coding agents are quickly becoming part of day-to-day engineering work, but most people still lack visibility into what these agents are actually doing. Marius will share findings from Apollo’s research into tens of thousands of real-world coding agent traces: from direct security risks like dang...
