Your project has grown. What started as four HTML pages now has a dozen files across several folders. Maybe you've added a blog section, or a portfolio gallery, or integrated some third-party tool.
Claude Code handles big projects well. But the way you use it needs to evolve. The casual "fix the page" instructions that worked with four files need more precision when you have forty.
Context Management: Fresh Sessions
The most important habit for bigger projects: start fresh sessions often.
Every time you type claude, you get a new conversation. Claude reads your files, reads your CLAUDE.md, and starts with a clean slate. No baggage from yesterday's confused session. No leftover assumptions from a conversation that went sideways.
Start a new session for every new task. Fixed a bug? Start fresh. Adding a new page? New session. Changing the design? New session.
