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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 13 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 | $0.00059 | $0.00723 |
| Opus 5.5 | $0.00024 | $0.00289 |
| Sonnet 5.5 | $0.00012 | $0.00145 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade A, and why
separateweb-capture 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.
What it actually says
SeparateWeb Capture
Use this skill when the user asks:
separateweb capture <url>
npx separateweb-capture capture <url>
separateweb patch <path>
Use npx when the package is not linked globally. This is the safest default for Claude Code personal skills:
npx separateweb-capture capture <url>
npx separateweb-capture patch <path>
Use separateweb-capture with no capture command only to install the local skill payload:
npx separateweb-capture
npx separateweb-capture --target claude
npx separateweb-capture --target both
If separateweb is installed or linked globally, this shorthand is also valid:
separateweb capture <url>
separateweb patch <path>
If running from the plugin root, the local script is also valid:
node scripts/capture.mjs capture <url>
node scripts/capture.mjs patch <path>
Optional flags:
--out <dir>
--path <dir>
--width <px>
--height <px>
--max-pages <n>
--single
--all
Capture behavior:
capture https://example.comandcapture https://example.com/crawl same-origin paths by default.capture https://example.com --singlecaptures only the home page.capture https://example.com/pathcaptures only that page by default.- Use
--singleto force one page. - Use
--allto force same-origin crawl from any start URL. - Captured items are grouped by type under
items/<kind>/.
Examples:
npx separateweb-capture capture https://domain.com
npx separateweb-capture capture https://domain.com --single
npx separateweb-capture capture https://domain.com/about
npx separateweb-capture capture https://domain.com/about --all
Patch selection:
npx separateweb-capture patch /absolute/output/path
npx separateweb-capture select captures/<jobId>/manifest.json
npx separateweb-capture create captures/<jobId>/manifest.json --items 1,3,5 --path /absolute/output/path
Use patch <path> to set the default machine path where future capture outputs are written. Use create only when exporting selected items from an existing manifest.
Default output:
captures/<jobId>/site-manifest.json
captures/<jobId>/page-001-<slug>/full-page.png
captures/<jobId>/page-001-<slug>/manifest.json
captures/<jobId>/page-001-<slug>/items/<kind>/*.png
Single-page capture writes full-page.png, manifest.json, and items/<kind>/*.png directly under captures/<jobId>/.
After running, report:
CapturedManifestBlocks- exact error if capture failed
Do not start a Nuxt dev server. This plugin is script-only.
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.

separateweb-capture is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (1,346 stars, last pushed yesterday), licensed Apache-2.0. It adds 59 tokens to every session and 723 once invoked, about $0.0002 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.
