Capture quick notes in Markdown with Claude Code

Save a single thought or reminder as a dated Markdown note while preserving an existing file with the same name.

Install in Claude Code

A Claude Code workspace with a notes directory. The example uses a fixed date to show naming and collision handling.

Review `.claude/skills/notes/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.claude/skills/notes/` in your project and save the reviewed file as `.claude/skills/notes/SKILL.md`.
Start Claude Code from that project's root, then select `/notes` in the slash menu.

Example task

Assume today's date is 2026-08-11. The notes/2026-08-11-filter-reminder.md file already holds a different note. The new line is `Check mobile filter spacing after the preview` and its short topic is filter-reminder.

What to check

Keep the old note and save the reminder as `notes/2026-08-11-filter-reminder-2.md`. Date it 2026-08-11, retain the supplied line, and report the saved path.

Frequently asked question

What happens if a quick note has the same filename as another note?

Use a date and short topic in the filename. On a collision leave the existing note in place and add a numbered suffix. Keep one note per file.
