Came across the recent Claude Code leak from Anthropic, and what stood out wasn t the leak itself, but what it revealed about how these systems actually work.

• A source map file accidentally exposed ~500k lines of TypeScript

• Turns out Claude Code is basically a multi-step prompt orchestration system, not some mysterious black box

• Includes things like:

  • layered prompt pipelines ( prompt sandwich )

  • fake tools to prevent model distillation

  • simple frustration detection (regex for rage prompts )

• Even hints at future features like background agents and persistent memory systems

What s interesting is this:

Mozilla recently announced that they're shutting down Pocket. I used to use Pocket a lot back in the day, but I don't find myself regularly saving articles that much now.

For those that are still using Pocket, what are you planning to switch over to?
