VS Code Pets is a popular editor extension category leader. Codex Pets focuses on Codex-compatible downloadable pet packs and agent-readable registry access.
You want pet packs designed for Codex rather than a VS Code extension.
You need public manifest, OpenAPI, llms.txt, or MCP discovery.
You want downloadable ZIP packages with pet.json and spritesheet assets.
You want README badge, card, or iframe share snippets for approved pets.
Agent-readiness difference
Codex Pets exposes its registry through MCP, JSON, TOON, OpenAPI, sitemap, llms.txt, and llms-full.txt. That lets coding agents inspect the available pets and produce install instructions without scraping a visual gallery.
