A LEARNING SURFACE FOR CLAUDE CODE
Six free resources for getting deep on Anthropic's terminal-native coding agent. Pick by where you are — reference, guided walkthrough, deep dives, copy-paste recipes, or the ecosystem map.
Cheatsheet
Dense single-page poster. Every CLI flag, hook event, skill/agent surface, settings field, slash command. Ctrl-F friendly. Print as A3.
Master Class
Guided 12-module walkthrough from first claude session to headless CI/CD. TL;DR-first per module. About 60 minutes end-to-end. Start here if you're new.
/goal Class
Deep dive on the /goal command — worker vs evaluator architecture, anatomy of a good condition, anti-patterns. Read before running unattended agents.
Hook Cookbook
10 production-ready hook recipes covering all 7 lifecycle event families. Each one: When · Payload · Script · Wire-up · Gotcha. Copy, paste, customize.
Routing Class
Extend Claude Code with CCRouter — the local proxy that routes requests to any model by task type. 4 modules of theory + 8 copy-paste routing configs (cost split, failover, long-context, Ollama).
Marketplace
The official Anthropic plugin marketplace — /plugin UX, three install scopes, claude-code-setup as the canonical bootstrap, 14 curated picks across 6 categories, third-party marketplaces, security model.
What this is
Four standalone resources, designed to compose. The cheatsheet is the dense reference — always one Ctrl+F away. The Master Class is the linear path for newcomers. The /goal Class and Hook Cookbook are depth drops on specific surfaces. Every page has a Resources ▾ dropdown so you can jump between them at any time.
