This repository is a curated collection of visual theme ("skin") configuration files for the Hermes CLI agent, an AI assistant terminal application. It does not ship or implement the agent itself; instead, it provides 16 YAML-based skin definitions (e.g., pirate, vault-tec, catppuccin, neonwave) that control banner colors, spinner animations, branding text, ASCII art banners, and tool emojis. The repository includes a Python validation script (`validate_skins.py`) that checks all skins against a required schema (28 color keys, spinner lists, branding strings, screenshot existence), a screenshot generator (`generate_screenshots.py`) that renders each skin's banner via ANSI-to-HTML-to-PNG conversion, and a GitHub Actions CI workflow that runs validation on push/PR. The architecture is a configuration library with supporting tooling; it is not a standalone application. The core value lies in the hand-crafted ASCII art and carefully tuned palettes for each theme, alongside a strict, machine-verifiable schema that enforces consistency across contributions.
