This is how Anthropic uses Claude Code internally.
10 tips from the creator, Boris Cherny:
1. Runs 5 Claudes in parallel
He keeps five Claude Code sessions open at once. Each works on a different task. A Stop hook pings him when one finishes or needs input, so he never babysits a single window.
2. Works across devices
He starts work on desktop in
claude.ai/code. When he leaves the office, he picks up the same session on the iOS app. The context follows him.
3. Always runs Opus with thinking
He picks the strongest model for every task. It is slower per turn but produces fewer retries, which makes the overall loop faster.
4. One shared
CLAUDE.md
His team commits a single rules file to the repo. Every time Claude slips up, they add a new rule. The file gets smarter with every mistake.
5. Tags @claude in pull requests
When teammates leave feedback on his PRs, he tags @claude in the thread. Claude reads the comments and updates
CLAUDE.md from them automatically.
6. Plan Mode before execution
He hits Shift+Tab twice before any real task. Claude writes a plan first. He reviews it, tweaks if needed, then lets Claude ship the whole thing.
7. Slash commands for repeat work
Every repeat task becomes a slash command. His /commit-push-pr command handles the full Git flow in one line. No typing the same prompt twice.
8. Sub-agents for parallel jobs
He spawns sub-agents with single responsibilities. One runs code-simplifier across the codebase. Another runs verify-app to check the build.
9. --dangerously-skip-permissions
He runs Claude in a sandboxed environment with this flag on. No permission prompts break his flow. The sandbox keeps the blast radius contained.
10. Plugs Claude into his team's tools
Claude sends Slack messages, pulls company data, and checks error reports. The same apps his team uses every day, now driven by Claude.
The most important tip:
Give Claude a feedback loop to verify its own work.
It 2 to 3x's the output quality.
The other ten are workflow.
This one is the multiplier.
