Claude Code tip: put this rule in your AGENTS or CLAUDE file, and from then on Opus 5.5 𝘁𝘂𝗿𝗻𝘀 𝗯𝗮𝗿𝗲 𝗻𝘂𝗺𝗯𝗲𝗿𝘀 𝗶𝗻𝘁𝗼 𝗰𝗵𝗮𝗿𝘁𝘀 𝘆𝗼𝘂 𝗰𝗮𝗻 𝗰𝗹𝗶𝗰𝗸 𝗼𝗽𝗲𝗻 to see the trend. Stat cards, dashboards, profile pages: all of them get the upgrade.

Send this to Claude Code and it adds the rule to your project's instructions 👇
"Add the rule below to this project's instructions: the CLAUDE file if there is one, otherwise the AGENTS file. Then show me what you added.

## Numbers in the UI
When a screen shows stats (stat cards, profile pages, dashboards):
- Many numbers of different kinds: split them into tabs
- Write each one as label + value + one helper line (a rate, a comparison or a time range). Compute helpers from existing data only; if you can't, ask me
- Make the key few numbers clickable tabs that open a small chart: bars or a line, plus an average line
- Chart only real history. Under 4 data points: keep the number, never invent sample data
- Zero or no data: show an empty state
- Reuse the project's existing tab and chart components, no new dependencies"
