Claude companion

Two companion volumes to the principles.

The principles describe KMS architecture. These two companion volumes sit alongside: the Primer covers Claude primitives the principles assume. The Notebook is a curated reading log — articles and threads worth holding onto, each pinned to its key insight.

  1. PublicPrimerThe generic Claude primitives the principles assume — subagents, skills, CLAUDE.md, memory, hooks, MCP, long context, prompt caching.
  2. Invited readersNotebookCurated summaries of articles, posts, and threads I've found useful — with the key insight pulled out and linked back to the source.
