ai-tools

日本語

A marketplace repository for distributing AI agent skills and plugins for Claude Code and Codex.

Highlights

• Publishes multiple plugins through .claude-plugin/marketplace.json
• Publishes Codex plugins through .agents/plugins/marketplace.json
• Provides an APM marketplace manifest through marketplace.yml and generated marketplace.json
• Includes installable skill collections such as agent-skills, takt, and software-design
• Keeps skills/, .agents/skills/, and .claude/skills/ links for tools that consume plain skill directories directly

Installation

Claude Code Plugin

/plugin marketplace add j5ik2o/ai-tools
/plugin install git@ai-tools
/plugin install github@ai-tools
/plugin install agent-skills@ai-tools
/plugin install takt@ai-tools
/plugin install software-design@ai-tools

Codex Plugin

Register this repository as a Codex plugin marketplace, then install the plugins you need:

codex plugin marketplace add j5ik2o/ai-tools --ref main
codex plugin add git@ai-tools
codex plugin add github@ai-tools
codex plugin add agent-skills@ai-tools
codex plugin add takt@ai-tools
codex plugin add software-design@ai-tools

Verify the installation, then start a new Codex task so the installed plugins are loaded:

codex plugin list

Agent Package Manager

apm marketplace add j5ik2o/ai-tools --name ai-tools
apm install software-design@ai-tools

Available APM package names are git, github, agent-skills, takt, and software-design.

GitHub CLI Skill

GitHub CLI provides gh skill for installing agent skills from GitHub repositories. See the gh skill manual for the current preview behavior.

Install a specific skill from this repository:

gh skill install j5ik2o/ai-tools j5ik2o-deep-research-read-me --agent codex --scope user --pin main

Install every skill exposed through the standard skills/ directory:

gh skill install j5ik2o/ai-tools --all --agent codex --scope user --pin main

The skills/ directory is the default discovery entry point. Mirrored links are also kept under .agents/skills/ and .claude/skills/; pass --allow-hidden-dirs only when you intentionally want gh skill to include hidden skill directories during discovery.

Skill-directory-based CLI

npx skills add j5ik2o/ai-tools

Creating a New Skill

1. Copy template/SKILL.md.template to plugins/agent-skills/skills/j5ik2o-<your-skill>/SKILL.md
2. Edit the frontmatter (name, description) and add instructions
3. Create a symlink in skills/ if you want direct CLI consumption:

   ln -s ../plugins/agent-skills/skills/j5ik2o-<your-skill> skills/j5ik2o-<your-skill>
   

4. Add or update entries in .claude-plugin/marketplace.json if you are publishing a new plugin collection

Maintaining the APM Marketplace

This repository keeps marketplace.yml as the APM authoring source and commits the generated marketplace.json for consumers.

APM is managed through mise:

mise install
mise run apm:version

Preview marketplace resolution without writing files:

mise run apm:marketplace:check

Regenerate marketplace.json from marketplace.yml:

mise run apm:marketplace:build

Package refs in marketplace.yml are pinned to commit SHAs for reproducible APM builds. Update those refs when publishing a new marketplace revision.
