Skills Collection

Portable Agent Skills that use the common SKILL.md folder format. Each skill is stored as source under skills/; packaged .skill archives are stored separately under packaged-skills/.

Skills

• apng-creator - Create an APNG from a numerically indexed PNG frame sequence.
• batch-image-compressor - Compress JPEG and PNG images without changing resolution or format.
• generate-tokens-from-figma - Generate design token reports and DTCG token files from Figma variables and styles.

Use the folders under skills/ for source editing and manual installation. Use the archives under packaged-skills/ only when a tool or marketplace expects a single packaged artifact.

Installation Guide

There are two practical ways to install these skills: ask an agent to install them for you, or copy/link the skill folders manually.

Option 1: Ask an agent to install automatically

Open your target agent and give it one of these prompts.

Install the <skill-name> skill from this repository's skills/<skill-name> folder.
Install it as a global skill for the agent I am using. Keep the folder name
<skill-name> and include all bundled files such as scripts/, references/, or assets/.
After installing, list available skills or tell me how to verify it loaded.

Install the <skill-name> skill from this repository's skills/<skill-name> folder
as a project-local skill in the current repository. Keep the folder name
<skill-name> and include all bundled files. After installing, list available
skills or tell me how to verify it loaded.

For a project-local install, replace "global skill" with "project-local skill in the current repository."

Option 2: Install manually

Run commands from the root of this repository unless noted otherwise. Replace <skill-name> with the folder name of the skill you want to install.

Codex

Install globally:

mkdir -p ~/.codex/skills
cp -R skills/<skill-name> ~/.codex/skills/<skill-name>

Restart Codex after installing so it reloads the skill list.

Claude Code

Install globally:

mkdir -p ~/.claude/skills
cp -R skills/<skill-name> ~/.claude/skills/<skill-name>

Install for one project:

mkdir -p /path/to/project/.claude/skills
cp -R skills/<skill-name> /path/to/project/.claude/skills/<skill-name>

Claude Code can invoke loaded skills automatically, or directly with /<skill-name>.

Gemini CLI

Install from the local folder:

gemini skills install ./skills/<skill-name>
gemini skills list

For development, link the whole local collection instead of copying it:

gemini skills link ./skills
gemini skills list

If Gemini CLI is already running, use /skills reload.

OpenCode

Install globally:

mkdir -p ~/.config/opencode/skills
cp -R skills/<skill-name> ~/.config/opencode/skills/<skill-name>

Install for one project:

mkdir -p /path/to/project/.opencode/skills
cp -R skills/<skill-name> /path/to/project/.opencode/skills/<skill-name>

OpenCode also recognizes the shared Agent Skills paths ~/.agents/skills/<name> and .agents/skills/<name>.

OpenClaw

Install globally:

mkdir -p ~/.openclaw/skills
cp -R skills/<skill-name> ~/.openclaw/skills/<skill-name>

Install for one workspace:

mkdir -p /path/to/workspace/skills
cp -R skills/<skill-name> /path/to/workspace/skills/<skill-name>

OpenClaw also recognizes shared Agent Skills paths such as ~/.agents/skills/<name> and <workspace>/.agents/skills/<name>.

Compatibility Notes

• The portable source format is a directory containing SKILL.md plus optional supporting files such as scripts/, references/, or assets/.
• Product-specific metadata is intentionally omitted from these skills.
• Some tools load new skills only after restart or reload.
• Treat third-party skills as code: read SKILL.md and bundled scripts before enabling them.
