v0.1.0 — Initial public release

First public release.

What this is

A reusable Codex skill that fixes the 72-frame desktop pet failure mode. Encodes a repeatable workflow:

• character bible first
• row semantics second
• tiny-UI readability before polish
• approved vs unapproved gating
• manual slicing with explicit guidance
• deterministic packing of per-frame inputs
• validator before install (sheet + pet.json install contract)

What's bundled

• SKILL.md — full workflow, prompting rules, slicing/packing rules
• references/ — row semantics, acceptance ladder, slicing guide
• scripts/pack_codex_pet.py — assembles per-frame inputs into a 1536×1872 spritesheet, one scale per row
• scripts/validate_codex_pet.py — checks dimensions, alpha, opaque-background errors, edge contact, row drift,
  and the pet.json install contract
• agents/openai.yaml — Codex UI metadata
• MIT License

Copy or symlink into your Codex skills directory:

  ~/.codex/skills/codex-pet-generator

  Use $codex-pet-generator to turn these character refs into a validated Codex desktop pet.
