/goal in Claude Code: keep a session running until the condition holds

/goal in Claude Code: keep a session running until the condition holds

Anthropic shipped the /goal slash command. A session-scoped wrapper over a prompt-based Stop hook: you write a condition, a small evaluator reads the transcript after each turn, and the session ends only when it says yes. When to reach for /goal, when for /loop, when for a Stop hook — and why you write the condition for Haiku, not for the main model.

Why Your Website Should Serve Markdown to AI Agents

Why Your Website Should Serve Markdown to AI Agents

AI agents waste tokens parsing your navbars and cookie banners. I built an open-source library called next-markdown-mirror that fixes this — and it costs $0.
