Awesome Codex & ChatGPT Plugins

A curated list of awesome plugins, skills, and resources for OpenAI Codex and ChatGPT.

OpenAI documents plugins and skills for Codex, packaging skills, MCP servers, and app integrations into shareable, installable bundles across the Codex app, CLI, and IDE extensions.

Codex is now available inside the ChatGPT desktop app, while remaining a distinct coding workspace. OpenAI plugins can support workflows in ChatGPT, Codex, or both; this repository remains a Codex-compatible marketplace.

New plugin workflow:

1. Create with $plugin-creator
2. Validate with plugin-scanner. The catalog-owned centralized scan must report a normalized score ≥ 75/100 before merge.
3. Optionally gate your source repo with the HOL scanner GitHub Action. Catalog admission uses the centralized scan; source-repo scanner CI is recommended but not required.
4. Ship or submit with confidence

Quick preflight

pipx run plugin-scanner lint .
pipx run plugin-scanner verify .

Scanner Requirements (Mandatory for This List)

All plugins submitted to Awesome Codex Plugins must pass the HOL AI Plugin Scanner:

See the full guide: SCANNER_GUIDE.md
See contributing requirements: CONTRIBUTING.md

This repo publishes a Codex repo marketplace at .agents/plugins/marketplace.json. The marketplace points at mirrored installable plugin bundles under ./plugins/, so a clone of this repo can act as a curated plugin source in Codex.

Use this marketplace in Codex

Install plugins directly from this curated list by pointing Codex at the repo marketplace:

CLI:

# Add this repo as a marketplace source (one-time setup)
codex plugin marketplace add \
  'https://github.com/hashgraph-online/awesome-codex-plugins.git' \
  --ref 'main' \
  --sparse '.agents/plugins' \
  --sparse 'plugins'

# Then browse and install (the marketplace name is derived from the repo name)
codex plugin list --source awesome-codex-plugins
codex plugin install <plugin-name> --source awesome-codex-plugins

Do not use the raw marketplace.json URL with codex plugin marketplace add. The Codex marketplace command clones a Git repository, so a raw GitHub file URL is treated like a repo URL and fails with remote: 404: Not Found.

Desktop App / IDE Extension:

1. Open Codex settings → Plugins → Next to search plugins input click on menu and select → +Add More...

2. Add this URL:

https://github.com/hashgraph-online/awesome-codex-plugins.git

3. The curated plugin list appears as an available marketplace source.

Each plugin entry includes a source.path pointing at a mirrored bundle under ./plugins/ in this repo, so installations are fast and reproducible without hitting upstream repos at install time.

Development & Workflow

• A Team - A complete engineering team in one folder with 26 specialist agents, 20 workflow skills, an orchestrator, and quality gates; integration and hook support vary by coding platform.
• Aegis - An agentic skills framework & software development methodology that works: planning, TDD, debugging, and collaboration workflows.
• Agency Continuity Audit - Read-only audit that distinguishes durable agent goals, state, corrections, restart evidence, authority boundaries, scheduler claims, and commercial proof from self-reported health.
• Agent Deck - One MCP for context management: bind self-improving playbooks, MCP tools, and API keys to the session.
• Agent Guard - Local-by-default, no-telemetry hooks block or mask secret leaks in Claude Code and Codex, with opt-in PII filtering and Git/CI backstops.
• Agent Harness Skills - Designs agent-ready repository harnesses with entrypoints, validation surfaces, runtime evidence, delivery records, and atomic commit guidance.
• Agent Retro - Weekly retro of how you use Codex and Claude Code: 12 animated slides of usage stats with four evidence-backed coaching tips, built locally from your own logs.
• Agent Workflow System - 一套中文AI工作流系统：7个协作技能 + 行为规范宪法 + 会话恢复机制，模糊目标→可执行任务，全生命周期引导。Codex & Claude Code 双平台，新手友好。
