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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00082 | $0.01808 |
| Opus 5.5 | $0.00033 | $0.00723 |
| Sonnet 5.5 | $0.00016 | $0.00362 |
| Haiku 4.5 | $0.00008 | $0.00181 |
Grade A, and why
seo-competitor-pages 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.
This is a copy
97% identical to seo-competitor-pages — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Competitor Comparison & Alternatives Pages
Create high-converting comparison and alternatives pages that target competitive intent keywords with accurate, structured content.
Page Types
1. "X vs Y" Comparison Pages
- Direct head-to-head comparison between two products/services
- Balanced feature-by-feature analysis
- Clear verdict or recommendation with justification
- Target keyword:
[Product A] vs [Product B]
2. "Alternatives to X" Pages
- List of alternatives to a specific product/service
- Each alternative with brief summary, pros/cons, best-for use case
- Target keyword:
[Product] alternatives,best alternatives to [Product]
3. "Best [Category] Tools" Roundup Pages
- Curated list of top tools/services in a category
- Ranking criteria clearly stated
- Target keyword:
best [category] tools [year],top [category] software
4. Comparison Table Pages
- Feature matrix with multiple products in columns
- Sortable/filterable if interactive
- Target keyword:
[category] comparison,[category] comparison chart

Data Accuracy Requirements
- All feature claims must be verifiable from public sources
- Pricing must be current (include "as of [date]" note)
- Update frequency: review quarterly or when competitors ship major changes
- Link to source for each competitor data point where possible

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
