Anthropic shipped 125 settings for Claude
The official docs cover 40
One developer found the other 85 and his API bill dropped from $340 to $87
- not by using a cheaper model
- not by writing shorter prompts
just by moving one line in a config file to the right place
memory scoped per project → past clients never bleed into new work Extended Thinking on Light by default → 18–25% fewer Opus tokens in week one cache_control moved to the right line → the fix that turned a $340 bill into $87 plugins and MCP servers toggled off when idle → saved 25–40K tokens per session per-project model override → Haiku for docs, Sonnet for infra, Opus only where it matters
most Claude users are running a $100/month tool at 30% of its actual capability
Thank you for such nice words!

yep
I’ll be glad to hear feedback from you later
Thank you for such a nice comment
