What it does

Update Codex Plugin is an agent skill from remotion-dev/remotion, published by the product's own GitHub organization. Update Remotion's published Codex and ChatGPT directory plugin to a released Remotion version. Prepare the ZIP from the official Codex plugin repository, preserve its listing metadata, and upload and publish through OpenAI Platform.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/prepare-release.py`).

It sits in Media & Creative, covering Video production. It works with Remotion and OpenAI. The repository describes itself as: 🎥 Make videos programmatically with React.

When your agent uses it

  • Tasks that involve Video production

  • “/update-codex-plugin”

Requirements

  • Python 3

6 steps, taken from the first numbered list in SKILL.md.

  1. Open the existing plugin and click Upload new version, **Upload plugin to
  2. In Upload new version, keep the existing verified Remotion developer

  5. When the requested version is approved and publication is authorized, select
  6. Verify Publication Version shows the target version as Published.

What it can do on your machine

Read from SKILL.md and the folder at commit 32af7e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • bun
    • codex

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • platform.openai.com
    • chatgpt.com
    • github.com
    • developers.openai.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Update Codex Plugin loads about 1.7k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 834 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
