New to Claude Code

0 of 7

From first install to a tool that fits your hand. Set up the CLI, learn the moves that matter, then decide how it stacks up against the alternative.

  1. Install Claude Code CLI: 5-Minute Setup Guide (2026)

    Install the CLI, authenticate, and finish your first working session in about five minutes.

  2. Claude Code Cheat Sheet

    Keep this open in a tab: every command, shortcut, and flag on a single page.

  3. Claude Code Guide

    The complete reference. Skim the basics now, come back for the deep sections as you need them.

  4. AGENTS.md Patterns: What Actually Changes Agent Behavior

    Your instructions file is the highest-leverage config you have. These patterns actually change behavior.

  5. Claude Code Hooks Tutorial: 5 Production Hooks From Scratch

    Build five working hooks from scratch. This is the step from using the tool to shaping it.

  6. Claude Code Skills: Build Custom Auto-Activating Extensions

    Package your own workflows as skills that switch on exactly when they are needed.

  7. Claude Code vs Codex CLI 2026: Decision Reference

    You know the tool now. See how it compares to its main rival, and when each one wins.

Agentic Engineering

0 of 7

How to build, run, and trust AI agents that do real engineering work: the harness, the economics, the failure modes, and where the discipline is heading.

  1. The Evidence Gate: Proof Over Plausibility in AI Output

    Start with the working discipline: never accept “it should work” from an agent. Require proof.

  2. Agent Architecture

    The complete playbook for building an agent harness: skills, hooks, memory, subagents, and orchestration.

  3. Compounding Engineering: Why My Codebase Accelerates

    Why harness work pays compound interest: each feature you ship makes the next one cheaper.

  4. Loop Engineering: Loops Win Where Verification Is Cheap

    The rule that decides what to automate: loops win only where checking the result is cheap.

  5. What Actually Breaks When You Run AI Agents Unsupervised

    Seven ways agents fail when nobody is watching, and the signal that catches each one early.

  6. The Agent Operator's Handbook: Supervising What You Can't See

    Running agents is a role of its own. What supervision looks like when you cannot read every line.

  7. Agents Supersede the Reviewer, Not the Review

    Where this is heading: the reviewer role is dissolving while the review itself moves into the pipeline.

iOS with Agents

0 of 7

Ship Apple-platform apps with AI agents doing the heavy lifting, from wiring Claude Code into Xcode to the on-device models your app can ship.

  1. iOS Agent Development

    The end-to-end playbook for building iOS apps with agents. Start here and branch out.

  2. Two MCP Servers Made Claude Code an iOS Build System

    Wire Claude Code into Xcode so it can build, run tests, and read crash logs on its own.

  3. Hooks For Apple Development: Patterns That Save The Project

    An agent working near your signing keys needs guardrails. Four patterns that bound the damage.

  4. Xcode 27 Went Agentic

    What Apple ships natively: Xcode 27's built-in agents, and where they fit next to your CLI.

  5. Foundation Models Agentic Workflow: In-App Vs Tooling LLM

    Two AIs touch your app: the agent writing the code and the model shipping inside it. Keep their jobs straight.

  6. Foundation Models On-Device LLM: The Tool Protocol

    Put Apple's on-device model to work inside your app, starting with the Tool protocol.

  7. Foundation Models in iOS 27: Tool-Calling Control

    Control how the on-device model uses tools, with iOS 27's calling modes and built-in readers.
