23 skills shared by ChatGPT, Claude Code, and Codex

Your agent picks the right skill on its own.

Every skill says what it does and when to use it. ChatGPT, Claude Code, and Codex match those lines to your request and open the workflow that fits. You never have to remember its name.

How it works

A skill is a folder anchored by one instruction file.

The top of SKILL.md says what the skill does and when to use it. The host keeps that summary in mind and opens the rest only when the moment arrives. Some skills also include scripts, templates, or references that load only when needed.

Skillquiver v2.1.0: universal release candidate.

The update contains 23 shared Agent Skills, and the public plugin works in ChatGPT and Codex. The same source catalog also supports Claude Code. It runs through host-approved tools, with no hosted backend, account, authentication, bundled MCP server, hooks, or app UI.

Version 2.1.0 is prepared as an update to the existing listing under the public publisher name Drizzy07x. Portal review and publication remain separate external gates. See the privacy policy, terms, and support.

Install

Choose your host.

The universal Plugins Directory is recommended for ChatGPT and Codex once the listing shows version 2.1.0. Claude Code can install the same 23-skill source catalog from the repository marketplace.

Plugins Directory recommended

Open the Plugins Directory in ChatGPT, search for Skillquiver, confirm that the listing shows version 2.1.0, and select Add.

Until 2.1.0 is approved, the public listing may still expose the smaller Skillquiver Core catalog. ChatGPT uses @ mentions for explicit skill selection. Repository installs are intended for local development and Claude Code.

v2.1 migration: Skillquiver Doctor moved into skills/. Marketplace installs update normally; manual installations now copy only that directory.

Working together

One feature, from idea to merge.

These aren't 23 separate tricks. Almost every step of building something has a portable skill that fits it. A normal run in ChatGPT, Claude Code, or Codex looks like this:
