Study This

YouTube playlists:

python3 "$HOME/.claude/skills/youtube-playlist/youtube_playlist.py" "<url>" --format json --limit 20

Websites: Use the WebFetch tool to get the page content and extract title + description.

PDFs: If it's a local file, use the Read tool. If it's a remote URL, use WebFetch to download it, then read.

Step 3: Determine a study topic name

From the collected metadata, determine a concise, descriptive topic name. If references cover different topics, create separate notes.

Step 4: Search the vault for existing knowledge

IMPORTANT: Before creating the study note, search the vault for existing notes about this topic.

/Applications/Obsidian.app/Contents/MacOS/Obsidian search vault="Leo Knowledge" query="<topic keywords>" 2>&1 | grep -v "^2026\|installer\|Loading\|asar"

Also search with Grep for broader matches:

Grep: pattern="<topic keyword>" path="/Users/leonardoaraujo/work/leo-obsidian-vault" glob="*.md"

Exclude results from Things to Study/ folder — we want knowledge notes, not other study notes.

If existing notes are found:

1. Read the most relevant ones (up to 3-4 notes)
2. Add a "## Existing Knowledge in Vault" section to the study note listing what you already have, with wiki-links [[Note Name]]
3. Briefly summarize what each existing note covers so the user knows what's new vs. what they already have

Step 5: Create the Obsidian study note

Write to: /Users/leonardoaraujo/work/leo-obsidian-vault/Things to Study/<Topic Name>.md

Before creating, check if a note on the same topic already exists in Things to Study/. If it does, append the new references instead of creating a duplicate.
