Claude Code best practices
Official Anthropic docs

What it is
Anthropic's first-party guide, built around one stated premise: the context window is the most important resource to manage, and performance degrades as it fills. Covers /clear, /compact, /rewind, /btw, a CLAUDE.md keep-or-cut table, subagents for investigation, and the explore→plan→code→commit workflow.
Why it earns a slot
Read this before installing any of the compression tools. Most of the savings people chase with plugins come free from context discipline — and it names the failure patterns (kitchen-sink session, infinite exploration, over-specified CLAUDE.md) so you can recognize your own.
Neighbourhood
How Claude Code best practices sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
