1# Graph Colorize — Color-code the Obsidian Graph View
2 
3You are rewriting `$OBSIDIAN_VAULT_PATH/.obsidian/graph.json` so Obsidian's graph view tints nodes by tag, folder, or visibility.

5Obsidian stores graph settings in `<vault>/.obsidian/graph.json`. The `colorGroups` array is a list of `{query, color}` pairs; the first matching query wins per node. Queries use Obsidian's search syntax: `tag:#foo`, `path:"concepts"`, `file:foo`, etc. Color is `{"a": 1, "rgb": <packed-int>}` where the int is `(R << 16) | (G << 8) | B`.

91. **Resolve config** — follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global config → prompt setup). This gives `OBSIDIAN_VAULT_PATH`.
102. Confirm `$OBSIDIAN_VAULT_PATH/.obsidian/` exists. If it doesn't, the vault has never been opened in Obsidian — tell the user to open the vault once in Obsidian, then re-run.
113. **Warn the user if Obsidian is likely open**: Obsidian overwrites `graph.json` on close. Tell them to close the vault first, or be ready to reload (Cmd/Ctrl+R) and not touch the graph settings until they reload.

13## Step 1: Pick a Mode

15Infer the mode from the user's phrasing. If ambiguous, default to **by-tag**.

17| User intent | Mode |
18|---|---|
19| "color by tag", "color my graph", "make it colorful" (default) | `by-tag` |
20| "color by folder", "color by category", "color by directory" | `by-category` |
