Beepus Maximus Skills

Reusable Beepus Maximus agent skills and Claude Code plugin bundles for Apple platform engineering, product work, and project workflows. Skills are plain SKILL.md directories, so the same content can be used by Codex and Claude. Claude-only slash commands live under plugins/project-tools/commands.

What's Included

• Plugin bundles for Claude Code.
• Standalone skill directories for Codex or other agents that read SKILL.md.
• Thin Claude slash-command wrappers for selected project workflows.
• Example project instruction templates in example-setup/.

Installation

Claude Code Plugin

Install through the Claude plugin marketplace:

/plugin marketplace add 4eleven7/Claude-Skills
/plugin install ios-frameworks@claude-skills
/plugin install ios-platform@claude-skills
/plugin install swiftui@claude-skills
/plugin install uikit@claude-skills
/plugin install project-tools@claude-skills
/plugin install product@claude-skills

Update installed plugins:

/plugin marketplace update claude-skills

Codex Skills

Codex can use the same SKILL.md directories. For a local checkout, symlink skills into ${CODEX_HOME:-~/.codex}/skills so Codex reads the current repository copy:

mkdir -p "${CODEX_HOME:-$HOME/.codex}/skills"
ln -sfn "$PWD"/plugins/*/skills/* "${CODEX_HOME:-$HOME/.codex}/skills/"

Each installed skill directory should contain its own SKILL.md at the top level.

Use copies instead of symlinks when you want a pinned snapshot that does not change as the repository changes.

Local Development

Use the plugin directories directly while editing. Before publishing changes, verify:

• every skill directory has a top-level SKILL.md
• every SKILL.md has name and description frontmatter
• skill names are unique within the catalog
• Claude commands stay thin wrappers around skills

Apple framework skills for iOS and Apple platform development.

Skill	Use
activitykit	Reviews and writes ActivityKit code — Live Activities, Dynamic Island, Lock Screen presentations, push updates, and Activity lifecycle. Use when implementing live updating content outside your app.
