We'll blend Claude Code with custom TypeScript scripts, wire up interactive slash commands, and add browser automation to existing OSS tools to export polished WebM assets.
Dates, Times, and LLMs
How do you make an LLM amazing at dates? Relative dates, absolute dates, timezones, all that madness. Let's talk dates, times, and all that goodness.
Event-driven agentic loops
Key takeaway: treat agent interactions as an event log, not mutable state. Modeling user inputs, LLM chunks, tool calls, interrupts, and UI actions as a single event stream lets you project state for the UI, agent loop, and persistence without drift. We walk through effect-ts patterns for subscribing to the bus, deriving “current” state via pure projections, and deciding when to persist or replay events—plus trade-offs for queuing, cancelation, and tool orchestration in complex agent UX.

Vaibhav Gupta and Dex demonstrate the power of AI-assisted coding by implementing a complex timeout feature for BAML (a programming language for AI applications) in a live coding session. Starting from a GitHub issue that had been open since March, they showcase a systematic workflow: specification refinement, codebase research, implementation planning, and phased execution. Using Claude and specialized coding agents, they navigate a 400,000+ line codebase, implementing timeout configurations for HTTP clients including connection timeouts, request timeouts, idle timeouts, and time-to-first-token for streaming responses. The session highlights key practices like context engineering, frequent plan validation, breaking complex features into testable phases, and the importance of reading AI-generated code. In under 3 hours of live coding, they achieve what would typically take 1-2 days of engineering time, successfully implementing parsing, validation, error handling, and Python integration tests.

Now Dex and Vaibhav are gonna share some tips and tricks for pushing AI coding tools to their absolute limits, while still shipping well-tested, bug-free code. This isn't vibe-coding, this is something completely different.
Evaluating Prompts Across Models
AI That Works #16 will be a super-practical deep dive into real-world examples and techniques for evaluating a single prompt against multiple models. While this is a commonly heralded use case for Evals, e.g. 'how do we know if the new model is better' / 'how do we know if the new model breaks anything', there's not a ton of practical examples out there for real-world use cases.
