Use this skill when adding a new skill to the OPC Skills project. Follow every step below to ensure the skill meets all publishing requirements.

• The skill name is kebab-case (e.g., my-new-skill)

Checklist

1. Skill Directory Structure

Create the skill directory with required files:

skills/<skill-name>/
├── SKILL.md              (required) Main skill documentation
├── scripts/              (if skill has scripts)
│   └── *.py / *.sh
├── examples/             (recommended) Usage examples
│   └── *.md
└── references/           (optional) API docs, templates
    └── *.md

SKILL.md must include YAML frontmatter:

---
name: <skill-name>
description: Clear description. Include trigger keywords and "Use when..." contexts.
---

Use template/SKILL.md as a starting point:

cp -r template skills/<skill-name>

2. Skill Logo

Generate a pixel-art style SVG logo matching existing skill logos:

# Use the logo-creator skill
python3 skills/nanobanana/scripts/batch_generate.py \
  "Pixel art <subject> logo, 8-bit retro style, black pixels on white background, minimalist icon, clean crisp edges, no text, centered" \
  -n 20 --ratio 1:1 \
  -d .skill-archive/logo-creator/<date>-<skill-name> \
  -p logo

# Open preview to pick a logo
cp skills/logo-creator/templates/preview.html .skill-archive/logo-creator/<date>-<skill-name>/
open .skill-archive/logo-creator/<date>-<skill-name>/preview.html

# After picking (e.g., #5):
python3 skills/logo-creator/scripts/crop_logo.py <input>.png <output>-cropped.png
python3 skills/logo-creator/scripts/vectorize.py <output>-cropped.png skill-logos/<skill-name>.svg

Verify: skill-logos/<skill-name>.svg exists and matches the pixel-art style of other logos.
