TopicsFeature-based index

Jump straight to the configuration feature you need. Each topic gathers the chapters that touch it.

CLAUDE.md

Always-loaded project memory — the file Claude reads at every session start.

Rules

Conditional context — files loaded only when a glob pattern matches.

Skills & Agents

On-demand context — capabilities the LLM pulls in when it decides it needs them.

MCP

Tool context — external services as tools, and their context cost.

Hooks

Runtime layer — deterministic checks that run outside the LLM's view.

Plugins

Bundles of skills, MCPs, and tools — distribution and marketplaces.

Code Intelligence

Language-server grounding — confirm symbols, types, and references against the live repository.

Agent Teams

Multi-session coordination — peer-to-peer persistent sessions for work that outgrows a single conversation.

NOTE

Topics organize the same material along a feature axis instead of the book's chapter order. Use the sidebar (chapter order) for sequential reading; use Topics for quick "I need to look up CLAUDE.md / Hooks / MCP" lookups.
