@agentic.james: My Claude Code actually improves its own skills overnight, here's how. Every conversation you have with Claude Code, including every tool call and its thinking, gets stored in a JSONL transcript in your Claude folder. That's a complete paper trail of how it behaves, and almost nobody uses it. Since skills get invoked by tool calls, you can look in that transcript to see exactly how a skill changed the agent's behavior and whether it followed the instructions. Once you can see that, you can run an auto-research loop on it: one agent grades another agent's transcript after it used a skill, figures out what went wrong, and rewrites the skill so the next run is better. That's how your skills get sharper while you sleep. Link in bio.
