🔶 Use Github early and often
Once you connect CC to git, it gets access to your entire commit history
Meaning it will know about EVERY change you've ever committed, making it SO much more powerful
This will reduce hallucinations a ton. Connect CC to git right away

🔶Load up your context
CC's context management has gotten MASSIVE improvements the last few weeks
It now compacts intelligently, allowing you to keep context for a LONG time
Don't be afraid to load context by having CC review your architecture at the beginning of sessions

🔶Adjust eagerness
Claude Opus 4.5 is an incredibly eager model. It asks for forgiveness, not permission
The eagerness to make changes is why I love CC. But if you don't like this eagerness, Anthropic wrote a new CLAUDE rule you can put in your rules file:

🔶Be careful with the word 'think'
'Think' is the only word you can use with Claude Code that triggers extra token usage
If you are tight on budget or tokens, avoid using the word 'think' 'think more' or 'ultrathink'
Instead use 'evaluate' or 'consider'

🔶Use vision
Claude Opus 4.5 is the greatest vision model of all time
Meaning, it can analyze and understand images better than any other model
Make sure to use as many images as you can. I like to use them for debugging and visual inspiration
Just paste directly into CC!

🔶Parallel tool calls
Claude Opus 4.5 is the best model ever at tool usage. It's incredibly agentic
With this new CLAUDE rule Anthropic created, you can have CC use tools in parallel, increasing efficiency
Just place this in CLAUDE .MD: (give image to claude to extract text)

🔶 Reduce hallucinations
Claude's eagerness has some downsides
It will often make edits to files without truly understanding its purpose first
This new CLAUDE .md rule straight from Anthropic will fix that:

I started a Claude Code community if you want to join. Over 100 people in it. Tons of Claude Code videos plus weekly calls with everyone. Great place to learn vibe coding and meet builders:
