Reference · 9 Deep-Dives
Claude Code Toolkit
Expert's guide to agentic engineering. Not documentation — mental models, production architectures, and the pitfalls the docs don't warn about.
How to Read a Topic
Every topic is worked through the same four lenses. Start with the mental model; reach for the others when the work demands it.
Mental Model
The one idea to internalize before you touch the feature.
Playbook
Concrete, copy-ready setups for real workflows.
Compositions
How it combines with other features into architectures.
Pitfalls
The failure modes the docs don't warn you about.
The Nine Topics
Each is a self-contained deep-dive. Independent — start anywhere.
Where This Connects
Every topic here is a Claude Code feature — and each one implements a portable pattern. This is where the toolkit grounds out in technique.
