Tips, tricks, and lessons from building software — a personal dev blog by Tommy.
Bootstrapping a Project with /init
Run /init to generate a CLAUDE.md that teaches Claude how your project works.
Managing Tool Permissions with /permissions
Control what Claude can do without asking, using allow and deny rules through /permissions.
Checking Costs and Usage with /usage
See how much you're using and spending in a session with the /usage command.
Resuming Past Sessions with /resume and --continue
Pick up right where you left off using /resume in-session or the continue and resume flags from the shell.
Writing Your First Custom Slash Command
Turn a prompt you type over and over into a reusable slash command with a single Markdown file.
Passing Arguments to Custom Commands with $ARGUMENTS
Make custom commands flexible by feeding them input through $ARGUMENTS or positional $1, $2 slots.
