Quick Save Note

Save a focused note about the topic currently being discussed. This is the lightweight version of /save-knowledge — it saves one note about one topic without analyzing the full conversation history.

Prerequisites

Resolve the target vault path from the OBSIDIAN_VAULT environment variable. If it is not set, stop and tell the user to set OBSIDIAN_VAULT to the absolute path of their Obsidian vault (e.g., export OBSIDIAN_VAULT=~/Documents/Obsidian/MyVault).

What to do

1. Title: Use $ARGUMENTS as the note title. If no argument was provided, infer the topic from the most recent exchange in the conversation.

2. Check existing vault: Read $OBSIDIAN_VAULT/_index.md if it exists. Check if a file on this topic already exists.

   • If yes: update or append to the existing file.
   • If no: create a new file.

3. Determine placement: List the top-level folders inside $OBSIDIAN_VAULT and pick the one that best fits the topic. Create a new folder only if no existing folder fits.

4. Write the note with this structure:

---
title: Title From Arguments
date: YYYY-MM-DD
tags:
  - relevant-tags
source: claude-session
status: reference|runbook|decision|how-to
---

# Title

[Distilled knowledge from the current discussion. Keep it focused and precise.]

## Related
- [[links-to-related-notes]]

5. Update $OBSIDIAN_VAULT/_index.md if it exists and a new file was created.

6. Confirm to the user what was saved and where.

Rules

• Keep it focused — one topic per note.
• Distill, don't dump conversation verbatim.
• Preserve exact commands, configs, file paths, and versions.
• Use [[wikilinks]] to connect to other notes in the vault.
• Use kebab-case for file names.
