Claude for Developers: The Practical Guide

Claude has become a favorite among developers for one reason: it's noticeably better at holding and reasoning across large codebases without losing the thread.

This guide focuses on Claude Code (the CLI/agentic coding tool) and the general Claude chat interface, and how to use both like a professional instead of a hobbyist copy-pasting from a chat window.

What's inside: how to set up a CLAUDE.md file so Claude actually understands your architecture and conventions, when and how to use Plan Mode before non-trivial work, connecting real tools via MCP (GitHub, browsers, issue trackers, design files), using sub-agents to keep long tasks isolated and high quality, and how /rewind lets you safely attempt risky refactors.

You'll also get a real debugging workflow: the difference between a weak prompt and a strong one, a test-driven flow that works especially well with Claude Code, how to build custom slash commands for repeated tasks, and practical tips for managing context in long sessions so quality doesn't degrade.

This is free because it's the fastest way to see exactly how I use Claude day to day, if it's useful, check out the AI Coding Toolkit and n8n guides for the rest of the system.
