100 Practical Recipes for Claude Code Power Users — Updated for Opus 4.7You're past the basics. You want to use Claude Code the way senior engineers do: with MCP servers, automated Hooks, custom Skills, sub-agent teams, and cloud workflows that run while you focus on the hard parts.Claude Code Cookbook (Second Edition) is a practical reference of 100 standalone recipes across 16 chapters. Each recipe solves a specific real-world problem. Pick the recipes that match your current challenges, or read cover to cover to build a complete mental model of what Claude Code can do at scale.What's New in the Second EditionClaude Code has gained an entire new layer since the first edition. This edition rewrites about 30 recipes to match.Opus 4.7 is the new default, with Sonnet 4.6 for routine work and Haiku 4.5 for cheap parallel sub-agents. The new xhigh thinking effort tackles genuinely hard problems.Auto Mode replaces approve-each-tool prompts with a classifier that learns which commands you trust.Fast Mode streams output at roughly 2.5x the previous rate.Plugin Marketplace turns Skills into a shareable, versioned, discoverable artifact.Hooks doubled in scope: about two dozen lifecycle events including FileChanged, CwdChanged, PostCompact, and UserPromptSubmit, plus conditional clauses and dynamic context injection.Cloud workflows: /autofix-pr, /team-onboarding, Remote Control, and the new Ultraplan and Ultrareview commands that run on Anthropic infrastructure.Multi-device and Computer Use: drive Claude Code from Telegram, Discord, or iMessage. Approve tool calls from your phone. Automate native apps with Computer Use. Schedule cloud runs with Routines.Recipe numbers haven't moved. First-edition bookmarks still work.What's CoveredCLAUDE.md and Settings: project configuration that makes Claude Code work the way you think.Context and Cost: keep sessions focused and token spend predictable.MCP Servers: connect Claude Code to GitHub, web search, Playwright, databases, and APIs. Build custom MCP servers for your internal tools.Skills and Plugins: package repeatable workflows. Distribute them through the Plugin Marketplace.Sub-agents and Agent Teams: decompose complex tasks across parallel agents with clear handoffs.Hooks: automate quality gates and triggers at any of about two dozen lifecycle events.Cloud Workflows: /autofix-pr in CI/CD, Ultraplan for planning, Ultrareview for code review, and harness engineering for long-running agents.Multi-Device and Computer Use: drive Claude Code from your phone, automate GUI applications, and schedule cloud runs.Recipe FormatEvery recipe states the problem, gives a working solution with tested code, explains why the approach holds up, and links to related recipes. Each recipe also links to runnable sample code in the companion GitHub repository.Who This Book Is ForDevelopers with three or more months of Claude Code experience who want to move beyond one-shot promptingEngineers building agentic development workflows for professional codebasesTeams adopting Claude Code and looking for patterns to standardize onDesign for LongevityAI tooling changes fast.
