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 | $0.00101 | $0.02799 |
| Opus 5.5 | $0.00040 | $0.01120 |
| Sonnet 5.5 | $0.00020 | $0.00560 |
| Haiku 4.5 | $0.00010 | $0.00280 |
Grade A, and why
testing-bgs-modpack 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Testing BGS Modpack Batches (judgment skill)
This skill answers one question: "It's installed -- how do I PROACTIVELY verify this batch before declaring the batch good?"
BB84's source material is thin here. That is part of the skill's operating doctrine: do not manufacture a giant universal QA checklist. Test the batch's intended in-game impact, preserve save hygiene, query KB for game-specific commands/routes, and mark [GAP — needs user input] when the substrate is silent.
The Iron Law
+------------------------------------------------------------------------------------------------+
| A batch is not accepted because the game reached the main menu. It is accepted only after the |
| batch's intended in-game effect is observed in its target context, with no immediate local |
| breakage, and without baking unverified state into the user's main save. |
+------------------------------------------------------------------------------------------------+
Route gate (one primary skill per intent)
Use this skill when the user has already installed a batch and wants a proactive post-install verification pass: what to inspect, what commands/routes to use, what counts as enough evidence to move to the next batch.
Do not use this skill as the primary skill for adjacent intents:
| User intent | Primary skill |
|---|---|
| "It crashed", "FPS tanked", missing meshes, broken quests, bad logs, or any failure already observed | diagnosing-bgs-problems |
| "Should this mod go in the pack?" before install | evaluating-bgs-mods |
| Define pack style, batch size, rollback boundaries, naming/separator discipline | curating-bgs-modpack |
Enable/disable/reorder plugins or edit plugins.txt |
writing-bgs-load-order |
| Inspect records, conflicts, or override winners | xedit-conflict-audit / xedit-automation |
Terminal handoff: if proactive testing finds a failure signal, stop calling it "testing" and hand off to diagnosing-bgs-problems. A failed verification pass is not an invitation to improvise a fix inside this skill.
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.

testing-bgs-modpack is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (1,419 stars, last pushed yesterday), licensed Apache-2.0. It adds 101 tokens to every session and 2,799 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
