You can store reusable prompts as markdown files in .claude/commands/ inside your vault. Files in .claude/commands/*.md become available as /filename slash commands in Claude Code. Here's what a daily review command looks like:
Read today's journal entry at journal/$ARGUMENTS.md. If the file doesn't exist yet, create it with today's date as the title.
Scan tasks/ for any open items that aren't marked complete. List the top 3 that fit a focused work day.
At the bottom of the journal file, add an evening reflection section with three blank headers: What I completed, What I learned, What carries over tomorrow.
Save this as .claude/commands/daily.md. Run it with /daily 2026-02-25 to start a focused session. The $ARGUMENTS variable passes your date into the command.
A /weekly command can aggregate all daily notes and scan project folders for status changes. It calculates goal progress separately. The most valuable work Claude does here is not clever. It is clerical. These are the steps you skip when tired. Claude never skips them.
