What it does

Add New Package is an agent skill from remotion-dev/remotion, published by the product's own GitHub organization. Add a new package to the Remotion monorepo, including package scaffolding, monorepo registration, documentation, build scripts, and release checklist updates. Use when creating a new @remotion package.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Video production, Monorepo tooling and Project scaffolding. It works with Remotion, React, TypeScript and npm. The repository describes itself as: 🎥 Make videos programmatically with React.

When your agent uses it

  • Creating a new @remotion package
  • Tasks that involve Video production
  • Tasks that involve Monorepo tooling

Example prompts

  • “/add-new-package”

Workflow steps

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

  1. Create packages// with these files
  2. Register in monorepo
  3. Documentation (packages/docs/docs//)

What it can do on your machine

Read from SKILL.md and the folder at commit 1e4c5de. 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

    Shell commands in SKILL.md call:

    • bun

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

  • Network

    No URLs in SKILL.md.

    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

Add New Package loads about 777 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 262 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~777

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:54
    e` script is: `tsgo && bun --env-file=../.env.bundle bundle.ts`

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 262 words (~777 tokens).

“See the writing-docs skill for details on writing documentation.”
