Awesome Codex Plugins is a curated catalogue and marketplace of installable plugins, skills, and related resources for OpenAI Codex and ChatGPT. It helps people find, create, validate, and submit extensions for Codex workflows across its app, command-line interface, and IDE extensions. The catalogue add-ons are the plugins, skills, agents, and hooks listed or supported by this project.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00160 | $0.03140 |
| Opus 5.5 | $0.00064 | $0.01256 |
| Sonnet 5.5 | $0.00032 | $0.00628 |
| Haiku 4.5 | $0.00016 | $0.00314 |
Grade A, and why
seo-google scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 346 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google SEO APIs
Direct access to Google's own SEO data. Bridges the gap between crawl-based analysis (existing codex-seo skills) and Google's real-time field data: actual Chrome user metrics, real indexation status, search performance, and organic traffic.
All APIs are free. Setup requires a Google Cloud project with API key and/or
service account -- run /seo google setup for step-by-step instructions.
Prerequisites
Before executing any command, check credentials:
python scripts/google_auth.py --check --json
Config file: ~/.config/codex-seo/google-api.json
{
"service_account_path": "/path/to/service_account.json",
"api_key": "AIzaSy...",
"default_property": "sc-domain:example.com",
"ga4_property_id": "properties/123456789"
}
If missing, read references/auth-setup.md and walk the user through setup.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
