What problem does it solve? Customizing the appearance of Hermes across its CLI, TUI, and desktop GUI normally requires touching multiple surfaces; this Skill lets you define one YAML skin file that themes every surface at once and applies it live. ## Core Features & Use Cases - Single-file theming: Author one YAML skin in <hermes-home>/skins/ that colors the CLI, TUI, and desktop GUI through semantic keys like ui_accent, background, and ui_tool. - Live activation and tweaking: Apply a skin with hermes config set display.skin <name> or adjust one color in the active skin with hermes skin set <key> <hex>, with every surface repainting within about a second. - Use Case: A user asks for a synthwave look for Hermes. You copy the provided skin template, fill in a magenta-and-cyan palette, write it to the skins directory, activate it, and confirm the new theme landed on all surfaces. ## Quick Start Ask the agent to create a custom Hermes theme with your preferred colors and activate it across the CLI, TUI, and desktop.
