When adding or customising something, use this decision tree:
-
Is it a new config key or permission flag?
→ Start withhttps://docs.anthropic.com/en/docs/claude-code/settings -
Is it a new CLAUDE.md level behaviour or @import rule?
→ Start withhttps://docs.anthropic.com/en/docs/claude-code/memory -
Is it a hook event or automation trigger?
→ Start withhttps://code.claude.com/docs/en/hooks-guide, then cross-referencehttps://code.claude.com/docs/en/hooks -
Is it a workflow or agentic pattern?
→ Start withhttps://www.anthropic.com/engineering/claude-code-best-practices -
Is it about daily usage habits, Plan Mode, or subagent patterns?
→ Start withhttps://howborisusesclaudecode.com/
The Anthropic docs update frequently — the settings page in particular gained ~15 new keys between December 2025 and February 2026.
Recommended: re-read the settings and memory docs every 2–4 weeks.
