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.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 345 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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 | $0.00065 | $0.12274 |
| Opus 5.5 | $0.00026 | $0.04910 |
| Sonnet 5.5 | $0.00013 | $0.02455 |
| Haiku 4.5 | $0.00006 | $0.01227 |
Grade A, and why
maintaining-modding-environments 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 — 1,010 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Maintaining Modding Environments
When to use
- The environment is already set up and the user asks to maintain, refresh, update, or health-check it.
- The user says "register custom pack", "install my KB pack", "set
BGS_KB_USER_PACKS", or asks how to author a local KB pack. - The user asks how to maintain a mod knowledge base, a translator glossary KB, or a third-party localization KB for Skyrim/Fallout/Starfield.
- The user asks to install, upgrade, repair, or verify the standalone
xtl/bgs-translatorCLI after first-run. - The user asks to check or apply knowledge-base updates after first-run.
- The user asks to prune the KB cache or clean old pack versions.
- The user asks whether to pin a KB pack version, follow latest, or handle a
minPluginVersionwarning.
What this skill replaces
Use setting-up-bgs-modding-environment for first-run: MO2 detection, control-plane install, visible MO2 launch, first xEdit acquisition, first KB pack acquisition, and first semantic smoke.
This skill owns ongoing care after that first-run boundary: KB updates, cache hygiene, custom-pack authoring and registration, translator CLI maintenance, recurring environment health checks, and version-pinning advice.
Translator CLI maintenance
xtl is the standalone AI translation CLI/Web GUI launcher. It is published on
PyPI as bgs-translator; the portable plugin may include translator-facing
skills, but a fresh user machine still needs the Python package installed before
high-speed agents can call xtl.
Start every maintenance pass with an explicit readback:
# Check whether xtl is installed and can report its version/capabilities.
xtl version
# Inspect top-level commands before choosing a workflow.
xtl --help
If xtl is missing or too old, prefer an isolated user-level CLI install:
# Install the current release-candidate build as an isolated command-line tool.
pipx install bgs-translator==0.9.0rc1
# Upgrade an existing pipx-managed xtl install when a newer stable build exists.
pipx upgrade bgs-translator
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.

maintaining-modding-environments is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (1,326 stars, last pushed today), licensed Apache-2.0. It adds 65 tokens to every session and 12,274 once invoked, about $0.0003 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.
