# obsidian-layout-adjustment

A skill that restyles Obsidian through CSS snippets: it maps a plain description of an element to the right UI layer, patches the active snippets and checks the result on a screenshot.

## What it does

The skill works against a live vault. It reads `<vault>/.obsidian/appearance.json` and treats the `enabledCssSnippets` list as the source of truth, so old experiments never win over what is actually enabled. A phrase like "the tabs above the note" gets translated into an Obsidian object: workspace tab headers, not the book-and-dots row inside the pane. Before a subjective edit it copies the active snippets into `.obsidian/snippet-archive/`. They never land in `.obsidian/snippets`, so the snippet picker stays clean.

Then it touches one owning layer at a time: stage, shell, header, wrapper or child. It re-reads the current block, patches it, formats the CSS, reloads Obsidian and screenshots the affected area. If the screenshot shows no change, the skill checks which element owns the shape or restores the checkpoint. Stacking more rules on a wrong target is the trap it is built to avoid.

This is not a general CSS workflow and not a theme generator. Exact class names move with themes, plugins and app versions, so selectors get verified in the live vault first. `references/workflow-reference.md` holds the surface map of Obsidian, the change-type split and a list of common failure patterns.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill obsidian-layout-adjustment -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/obsidian-layout-adjustment/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/obsidian-layout-adjustment/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill obsidian-layout-adjustment -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/obsidian-layout-adjustment/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill obsidian-layout-adjustment -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/obsidian-layout-adjustment/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Ar9av/obsidian-wiki obsidian-layout-adjustment
```

2. **Manually: put the files in place**
- File: `.github/skills/obsidian-layout-adjustment/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill obsidian-layout-adjustment -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Ar9av/obsidian-wiki --path .skills/obsidian-layout-adjustment
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/obsidian-layout-adjustment/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill obsidian-layout-adjustment -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Ar9av/obsidian-wiki/tree/HEAD/.skills/obsidian-layout-adjustment/SKILL.md

## When to use it
- recolour the tab strip above a note without touching the rest of the UI
- fix icon contrast on a coloured sidebar
- give a note card a lifted look with shadow and spacing
- work out why a CSS snippet change never applied
- refactor active snippets and keep the accepted look

## Example prompts
- Make the tabs above the note dark grey and leave the rest alone.
- Round the note card: check the shell and overflow, then screenshot it.
- My snippet edit didn't take effect — find which layer actually owns that element.

# Obsidian Layout Adjustment

This skill is for changing how Obsidian looks with CSS files while working with the user's visual language.

Obsidian is always the same kind of environment: app frame, tab headers, side docks, view headers, pane shells, note surface, properties, file explorer, backlinks, graph, rendered markdown, and status bar. The vault, theme, snippets, plugins, and desired taste direction change, but the canvas stays Obsidian.

The core behavior is translation:

> the user names a visible Obsidian object. Translate that phrase into the stable Obsidian layer/backend object, edit the active snippets safely, screenshot the result, and keep iterating without losing good states.

This is not a general CSS workflow and not a fixed-theme generator.

## Normal Output Mode

This skill should make live styling work faster, not turn every small request into a report.

In normal use:

1. Say the mapping only when it prevents ambiguity.
2. Keep the mapping short: one sentence is usually enough.
3. Then act: inspect active snippets, checkpoint, patch, format, reload, screenshot.
4. Report the result concisely with changed files, checkpoint, and screenshot status.

Good normal update:

> "I’m treating 'tabs above the note' as workspace tab headers, not the arrows/book/dots view header. I’ll checkpoint active snippets, patch that selector family only, and screenshot the tab strip."

Do not write a long workflow report unless:

- the user asks for a plan, audit, review, or explanation.
- You are running evals or building this skill.
- You are refactoring without visual changes.
- The request is ambiguous enough that acting first would be risky.

The value is in preventing bad CSS loops while still moving quickly.

## Use The Reference

Read `references/workflow-reference.md` when:

- the user names a visible Obsidian object in natural language.
- The requested target could be more than one Obsidian layer.
```
