Deep dives into the internals that make Claude Code actually powerful
Slash Commands
Every built-in command dissected — /plan, /fix, /review, /ship and the full composable flag system.
Memory System
How Claude persists context across sessions — MEMORY.md index, four memory types, and decay strategies.
Skills / Superpower
Author reusable skill files that override default behavior — rigid vs. flexible patterns and routing logic.
Subagents
Spawning, orchestrating, and coordinating parallel agents — the Task tool, isolation modes, and result handling.
MCP Servers
Model Context Protocol — building servers, registering tools, and wiring external services into Claude's context.
Hooks & Plugins
PreToolUse, PostToolUse, and session lifecycle hooks — intercept, augment, and automate Claude's workflow.
