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.

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 | $0.00133 | $0.03931 |
| Opus 5.5 | $0.00053 | $0.01572 |
| Sonnet 5.5 | $0.00027 | $0.00786 |
| Haiku 4.5 | $0.00013 | $0.00393 |
Grade A, and why
interpreting-mod-author-instructions 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 — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Interpreting Mod Author Instructions (judgment skill)
This skill answers one question only: How do I correctly download/install per the mod author's instructions? It starts after evaluating-bgs-mods has said INCLUDE or CONDITIONAL INCLUDE. The job is not to decide whether the mod is good; the job is to read the author's说明 until the install path, file choice, prerequisite order, option logic, and consequences are actually understood.
The Iron Law
+-----------------------------------------------------------------------------------------------+
| No author说明, no install plan: understand the author's requirements, variants, and consequences |
| before touching downloads, FOMOD options, files, profiles, or load-order state. |
+-----------------------------------------------------------------------------------------------+
Route gate (one primary skill per intent)
Use this skill when the user is asking how to install a mod that is already worth considering: which file to download, which variant to choose, how to read a FOMOD, what prerequisites must be present first, how to name/track the installed components, or what the author means by a warning.
Do not use this skill as the primary skill for adjacent intents:
| User intent | Primary skill |
|---|---|
| "Should I add this mod?" / quality, risk, fit, pack-value before install | evaluating-bgs-mods |
Edit, enable, disable, sort, or reason about plugins.txt / load order |
writing-bgs-load-order |
| Inspect actual records, winners, overrides, or conflict severity | xedit-conflict-audit |
| Extract, inspect, or repack BA2/BSA archives | using-bgs-archive |
| Compile/decompile Papyrus PSC/PEX | using-bgs-papyrus |
| Translate plugin text or emit SST/XML dictionaries | using-bgs-translator |
Upstream gate: evaluating-bgs-mods. Inclusion says "worth considering"; it does not grant permission to install by habit.
Terminal handoff target: NONE. This skill ends with an install interpretation: selected file(s), selected option(s), prerequisite order, naming/tracking notes, and open gaps. If follow-on work requires archive/Papyrus/translator/tool operations, route to the existing tool skill for that operation.
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.
