DEEP DIVE: HOW CLAUDE CODE'S /INSIGHTS COMMAND WORKS

The /insights command in Claude Code generates an HTML report that analyzes usage patterns across a user's Claude Code sessions. The tool is designed to help users understand how they interact with Claude, what's working well, where friction occurs, and how to improve workflows. This post takes a look at how the tool works. For better insights, use Claude Code regularly, give feedback, don't filter yourself, and check in monthly to see how patterns evolve.

EXPENSIVELY QUADRATIC: THE LLM AGENT COST CURVE

It doesn't take much to start spending a significant amount of tokens on context. This problem compounds as conversations get longer and only gets exponentially more important with agent and subagent workflows. Agent developers need to keep this problem in mind when developing AI tools. This post provides an interactive tool that shows how quickly context size can take up a large percentage of a cache read.

PERPLEXITY CANNOT ALWAYS TELL RIGHT FROM WRONG

Perplexity is a function that measures models' overall level of surprise when encountering a particular output. It has gained significant traction in recent years as both a loss function and as a simple-to-compute metric of model quality. However, it may be an unsuitable metric for model selection. Perplexity will not always select for the most accurate model - any increase in model confidence must be accompanied by a commensurate rise in accuracy for the new model to be selected.

MOST PEOPLE CAN'T VIBE CODE. HERE'S HOW WE FIX THAT

Vibe coding has yet to reach mainstream consumers, remaining primarily the domain of technical users. Companies like Poke and Wabi are developing consumer-friendly AI products that eliminate complex technical setup and terminology. The real opportunity lies in creating tools that make software development accessible to non-technical users, similar to how Squarespace and Canva democratized websites and design.
