I Read the Claude Code Docs. All of Them. Here's What I Built.

Claude Code ships with roughly 40 discrete tools, a hook system covering 13 lifecycle events, and an Agent tool that can spawn subagents as flat tool calls. Most people use it as a single-session chat - type a request, get a response, move on. I spent six weeks reading every piece of documentation I could find about those primitives. Not the "getting started" guides - the actual behavior specs. How PreToolUse hooks can return exit code 2 to hard-block a tool call. How CLAUDE.md instructions get loaded into every session and every subagent.
