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: 3 findings, up to medium
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 →

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 | $0.00125 | $0.00893 |
| Opus 5.5 | $0.00050 | $0.00357 |
| Sonnet 5.5 | $0.00025 | $0.00179 |
| Haiku 4.5 | $0.00013 | $0.00089 |
Grade A, and why
codex-skin-pack-installer 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.

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Skin Pack Installer
Install verified Codex theme and skin packs without publishing private workspace screenshots or editing the signed app bundle.
This is a Skills.sh / npx skills installer for public-safe Codex desktop themes. It is meant for users searching for "Codex theme", "Codex skin", "install Codex theme", or "Codex Dream Skin packs" who want a real downloadable theme pack instead of a private screenshot.
Quick Start
Install this skill:
npx skills add ChannelerH/codex-skin-packs --skill codex-skin-pack-installer --global --agent codex --yes
Use the helper script to download and stage a pack:
python3 "$CODEX_SKILL_DIR/scripts/fetch_skin_pack.py" caishen-readable
The script downloads from the public GitHub release, validates the zip, extracts it to ~/.codexthemes/packs/<slug> by default, and writes a source manifest.
List available packs:
python3 "$CODEX_SKILL_DIR/scripts/fetch_skin_pack.py" --list
Workflow
- Identify the requested pack slug. If the user gives a vague style, list available packs and pick the closest match.
- Run
scripts/fetch_skin_pack.py <slug>unless the user already has a local pack folder. - Inspect the staged folder. It must contain
theme.json,background.png, and preferablyREADME.md. - Apply the staged pack through the user's active Codex theme manager or Codex Dream Skin workflow. Do not modify
app.asar, signed application bundles, private task data, or private screenshots. - Verify the Codex Home, Task, Diff, and Composer states for readability. If a live UI check is not possible, say that clearly and provide the staged path plus manual apply guidance.
- Always finish with the restore path: use the active theme manager's restore command or restore the default Codex appearance from the saved/original theme state.
Pack Slugs

What ships with it
2 files 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.
