Running Two Claude Code Accounts on One Machine
I keep a personal and a work Claude Code account on one laptop and run both at once. Out of the box that isn't possible — here's the pain point, and the one environment variable that fixes it.
How I Manage Claude Code Memory: What to Commit, What to Keep Local

Accept-Edits Mode for Faster Iteration
Accept-edits mode auto-approves file changes while still asking before running commands.
Read-Only Exploration of an Unfamiliar Codebase
Open a new repository in plan mode and let Claude map it out for you before any change is made.
