A timezone meeting planner with a mobile-first layout — Mini Tools & Utilities Prompt

1. In your project folder, start Claude Code and paste the filled prompt from the box above as the task (or save it as TASK.md and say "follow TASK.md").
2. Let it plan first (it will propose a file tree); approve the plan, then let it write files and run the app or tests itself.
3. Ask it to verify against the acceptance criteria in the prompt and fix failures before summarizing.
4. Keep the session open for follow-up features — Claude Code retains the codebase context.

Paste location: the Claude Code session in your project folder, or a TASK.md file it is told to follow.

1. Open ChatGPT (link below) — the quick-use button pre-fills the filled prompt from the box above in a new chat.
2. Review the filled variables once; if a variable still shows brackets, replace it with your own words.
3. Send it. For image results, ask for one variation at a time ("same image, warmer light") instead of re-rolling everything.
4. Save the winning output and copy the final prompt into your notes — ChatGPT does not keep a prompt library for you.

1. Open Gemini and paste the filled prompt from the box above (or use Copy + Open below).
2. For image or video-capable tasks, Gemini routes to its media models automatically; state the format (aspect ratio / length) in the first line, as the prompt does.
3. Regenerate once rather than editing mid-chat if the first result misses the format; then refine with one change at a time.
4. Export text results to Docs/Sheets from the share menu when you need them in office formats.
