Some context on what “rules” are for people who haven’t seen them: Claude Code has a built-in system for structured context beyond claude.md files. Rules support path matching (apply context only to specific files/directories), scoped organization, and structured formatting.

We have been running CodeYam Memory on our own repo for the past few weeks. The main difference we see is fewer repeated mistakes and less manual context maintenance. It’s still early, but it has meaningfully improved how we work with Claude Code.

If discussion gets too long for HN threads, we also have a Discord for questions and feedback: https://discord.gg/eFPUs7CeFw
