Hermes Skins

Custom skins (visual themes) for the Hermes CLI agent.

Skins control the visual presentation of Hermes: banner colors, spinner faces/verbs, response-box labels, branding text, tool activity prefix, and ASCII art banners. They don't affect personality or behavior — just how things look.

Quick Start

1. Browse the skins/ directory and pick one you like
2. Copy the .yaml file to ~/.hermes/skins/
3. Activate it:

# Session-only
/skin pirate

# Permanent (add to ~/.hermes/config.yaml)
display:
  skin: pirate

That's it. Missing values inherit from the default skin, so you only need to define what you want to change.

Built-in (ship with Hermes)

These are included for reference. They're already available in every Hermes install.

Creating Your Own

Drop a YAML file in ~/.hermes/skins/<name>.yaml. The name: field inside must match the filename.

Minimal Example

name: cyberpunk
description: Neon terminal theme

colors:
  banner_border: "#FF00FF"
  banner_title: "#00FFFF"
  banner_accent: "#FF1493"

spinner:
  thinking_verbs: ["jacking in", "decrypting", "uploading"]

branding:
  agent_name: "Cyber Agent"
  response_label: " ⚡ Cyber "

Everything you don't specify inherits from the default skin.

Full Schema

See SCHEMA.md for the complete list of configurable keys.

Contributing

Made a skin you're proud of? PRs welcome.

1. Add your .yaml to skins/
2. Include a brief description at the top
3. Make sure it has a name: key matching the filename
4. Define all 28 color keys (see SCHEMA.md) — dark skins that omit the status_bar_* and completion_menu_* keys will get mismatched colors from the default theme
5. Run python3 generate_screenshots.py and include the screenshot
6. Update the table in this README

How Skins Work

Hermes loads skins from two locations (user skins take priority):

1. ~/.hermes/skins/<name>.yaml (user custom)
2. Built-in skins hardcoded in skin_engine.py

The engine merges your skin on top of default, so partial skins work fine. Unknown skin names silently fall back to default.
