Claude Code
A practical guide to Claude Code's architecture, context system, extensions, parallel work, and daily workflows.
Getting Started
Setup
Getting Started
Install Claude Code, authenticate, initialize project context, and run your first session.
Safety
Permissions & Security
Choose permission modes, allow trusted commands, block risky actions, and use sandboxes.
Core Concepts
Architecture
Claude Code Architecture
See the six-layer mental model around the central agent loop.
Context
Context Management
Understand what loads into the window, what survives compaction, and how to keep sessions usable.
Memory
CLAUDE.md & Memory
Use CLAUDE.md, rules, AGENTS.md, and auto memory without bloating every turn.
Judgment
Advisor
Escalate hard decisions to a stronger model without spawning a full worker.
Extensions
Skills
Skills
Package reusable prompts, playbooks, commands, and supporting files that load on demand.
Isolation
Subagents
Delegate noisy or specialized work to separate context windows, foreground or background.
Integration
MCP
Connect Claude to databases, browsers, docs, and internal systems through MCP servers.
Automation
Hooks
Run deterministic command, HTTP, prompt, agent, or MCP hooks at lifecycle events.
Packaging
Plugins
Bundle skills, agents, hooks, and MCP servers into versioned extensions for teams.
Parallel Work
Ultracode
Dynamic Workflows
Use workflow scripts and ultracode to orchestrate many agents with cross-checking.
Worktrees
Git & Parallel Sessions
Use claude --worktree, checkpoints, and isolated branches for concurrent development.
Control
Agent View
Dispatch, monitor, reply to, and resume many background Claude Code sessions.
Teams
Agent Teams
Coordinate independent Claude Code instances with shared tasks and direct messaging.
Automation
Cloud Workflows
Practice
Planning
Plan Mode
Explore safely, approve a plan, then switch into implementation.
Workflows
Development Workflows
Run feature, bug fix, review, and PR workflows end to end.
Debugging
Debugging
Use plan mode, subagents, logs, tests, and rewind to find root causes faster.
Speed
Productivity
Learn the keyboard shortcuts, slash commands, session controls, and scripting flags.
