Removing AI Tells from Your Writing: A Skill That Turns One Flag into a Permanent Rule

Instead of hand-fixing an AI draft’s awkward sentences every time, I built a correction loop where one flag becomes a permanent rule. The Claude Code skill structure, how real rules were born, layering a community skill on top, and a seed file you can start with in ten minutes.

Reading Karpathy's Lord of the Rings Demo: What Long Context Plus Autonomy Opens for Builders

One paragraph of Tolkien, a million tokens, two hours of autonomous execution, a 3D film. Not a demo review: how the unit of delegation is changing, and where a builder’s work moves next.

Coding Agent Memory: Why Storing Everything Fails

I build an agent memory platform, and this week we reversed its direction. What store-everything memory breaks, and how to route state, facts, and principles to the tracker, the code, and memory.

How to Keep Your CLAUDE.md Light (and Why More Rules Make Agents Worse)

A CLAUDE.md does not get better as it grows. Why piling up rules degrades your agent, what belongs in the file, and where the rest should live: skills, hooks, and memory.

How to Make an AI Coding Agent Actually Yours

I built Monet to fix the agent that forgets yesterday’s conventions. How an agent that writes its own memory, reads what mattered, and grows with use actually works.

How Deep Does Your Coding Agent Setup Go?

Two developers, same tool, wildly different setups. How deep coding agent customization goes — from bare defaults to full pipelines — and what actually pays off.

Why We Need Behavioral Benchmarks for LLMs — Not Just More Knowledge Tests

What today’s LLM benchmarks actually measure, what they miss, and why we need behavioral benchmarks instead of more knowledge tests.

Token Economics: The Real Cost of AI Coding Agents

Two requests with near-identical input tokens, a 46x cost gap. How prompt caching really works, and why agents should be designed around structured state.

Does Your Coding Agent Need Memory?

Coding agents re-read the same files and re-ask the same questions every day. What memory actually does for an agent, how it differs from docs, and when it pays off.

How Are You Managing Your AI's Context Window?

Bigger context windows didn’t give better results. Notes on the context-management problems that keep recurring in real coding agent sessions.
