How does Claude Code understand your requests, invoke tools, and self-recover step by step? A source-code deep dive into the Agent Loop's core architecture — streaming responses, parallel tool execution, auto-compaction, and error recovery.
Claude Code has 5 config file locations: user-level (~/.claude/), project-level (.claude/), local-only, CLI flags, and enterprise managed settings. Learn which file to use when, how priority works, and why your settings might be ignored.
Stop clicking 'Allow' on every action. Configure Claude Code's permissions system — set allow/deny/ask rules, use wildcards, control MCP tools, and protect sensitive directories. Every permission option with practical examples.
Want to auto-validate commands before they run? Send Slack notifications when tasks finish? Claude Code hooks let you inject custom scripts at key moments — PreToolUse, PostToolUse, Stop, Notification — with practical examples.
Complete reference for every Claude Code settings.json field: environment variables, model selection, hooks, permissions, status line, theme, auto-updates, and more — all with working code examples you can copy and paste.
Create custom sub-agents for code exploration, architecture planning, and more — each with its own role, tools, and instructions.
API not connecting? MCP broken? /doctor auto-detects installation, connectivity, and config issues — here's how to fix them fast.
Control how hard Claude Code thinks about each task. Set effort to low for simple renames and save tokens. Crank it to max for complex refactors. Find the sweet spot between speed, cost, and code quality.
See real-time API costs, model pricing, and token breakdowns per session — /cost helps you make every dollar count.
Export conversations to files or clipboard for sharing, archiving, and review — so no valuable AI discussion goes to waste.
Lost hours of work to a wrong AI edit? /rewind restores your code and conversation to any point in history — like git reset for AI pair programming. Undo just the code, just the conversation, or both.
Install, enable, and manage plugins that add custom commands, skills, agents, and hooks — build your own AI development toolkit.
