Output Style Manager

A Claude Code plugin for managing and switching Output Styles. Install the plugin, pick a style, and it's applied automatically.

Quick Start

1. Install the plugin

/plugins
# → Add marketplace → dandelion0216/output-style-manager
# → Install "output-style-manager"

2. Choose a style

/set-output-style

Select from the list of available styles, or specify one directly:

/set-output-style concise

3. Start a new session

The selected style takes effect from the next session start.

To disable the active style:

/set-output-style off

Creating Custom Styles

Create your own style interactively and get a shareable URL:

/create-output-style

Claude will guide you through defining the style, save it locally, and optionally share it with the community. Shared styles appear in /add-output-style for all users.

Browsing & Importing Community Styles

Browse styles shared by others and install with one command:

/add-output-style

This shows a list of community styles from registry.json. Pick one and it's imported automatically.

You can also import directly from a URL or local file:

/add-output-style https://example.com/my-style.md
/add-output-style /path/to/my-style.md

Imported styles are saved to ~/.claude/custom-output-styles/ and can be selected with /set-output-style.

Style File Format

name: My Style
description: Brief description of the style

Your style instructions here. This content is injected as
additionalContext at the start of every Claude Code session.

Bundled Styles

Style	Description
concise	Minimal, direct responses with no filler
teaching	Step-by-step explanations with examples

How It Works

1. On session start, the SessionStart hook runs session-start.sh
2. The script reads the active style name from ~/.claude/output-style-active
3. It looks for the style file in custom styles (~/.claude/custom-output-styles/) first, then bundled styles (styles/)
4. The style content is injected as additionalContext

Sharing Styles

1. /create-output-style — create a style and upload it to Gist
2. Share the Gist URL directly — others can import it with /add-output-style <URL>
3. To list your style in the community registry, submit a PR adding an entry to registry.json

Token Cost Warning

The active style content is injected into every session as additional context. Keep style definitions concise to minimize token consumption.
