lateral-thinking

abpai/skills — Claude Code Marketplace + Codex Plugin Repo

A collection of reusable AI workflow plugins and skills for structured planning, cross-domain thinking, multi-model tooling, and developer productivity.

This repository now ships metadata for both runtimes:

• Claude Code plugins via .claude-plugin/plugin.json plus the root Claude marketplace
• Codex plugins via .codex-plugin/plugin.json plus a repo-scoped Codex marketplace at .agents/plugins/marketplace.json

Quick Start

Claude Code

# Add the marketplace (once)
/plugin marketplace add abpai/skills

# Install planning-oriented skills
/plugin install distill@abpai-skills
/plugin install lateral-thinking@abpai-skills
/plugin install codex-exec@abpai-skills
/plugin install pi@abpai-skills

Codex

Codex currently documents repo-scoped and personal local marketplaces. This repo includes a repo marketplace at .agents/plugins/marketplace.json that points at the top-level plugin folders with local source.path entries.

git clone https://github.com/abpai/skills.git
cd skills
codex

Then start or restart Codex in this repo, open the plugin directory, and install the plugins from the repo marketplace exposed by this checkout.

Codex public plugin-directory publishing is still documented as coming soon, so the Codex path in this repo is repo-local rather than the Claude-style remote marketplace flow above.

pi is intentionally excluded from the Codex marketplace in this repo. It is a Claude-native plugin that shells out to the codex CLI for second-provider research and review, rather than being installed into Codex itself.
