Hello Devs 👋 Over the last few months, AI agents have been evolving very quickly. We are no longer building simple chatbots that answer questions. Today, agents browse websites, execute workflows, monitor dashboards, interact with SaaS platforms, and perform actions that previously required manual
Every conversation you have with Claude Code is written to disk as JSONL, under ~/.claude/projects/. Your decisions, your dead ends, the bug hunt that took three sessions: it is all there. You have probably never opened one. The catch: the format is an internal implementation detail. No documentatio

The number looks exactly right — same letters, same digits you copied off the invoice — but the transfer won't go through. Before you blame the bank, know this: every IBAN carries a built-in self-check, and it just did
Disclosure up front: I'm the author of Lynkr, the open-source (Apache-2.0) proxy discussed below. All numbers come from a benchmark you can reproduce yourself — methodology linked at the end.
