What it does
Nullable New Params is an agent skill from remotion-dev/remotion, published by the product's own GitHub organization. Fix newly added optional parameters, optional React props, and optional type/interface members in Remotion monorepo diffs by converting internal APIs to required nullable values and updating call sites. Use when a PR, review, or user asks to forbid new foo?: T / param?: T additions except for exported or documented public APIs where requiring the value would be breaking.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml` and `scripts/find-new-optional-params.ts`).
It sits in Development, covering Video production, Monorepo tooling and Pull requests. It works with Remotion and React. The repository describes itself as: 🎥 Make videos programmatically with React.
When your agent uses it
- User asks to forbid new foo?: T / param?: T additions except for exported
- Documented public APIs where requiring the value would be breaking
Example prompts
- “/nullable-new-params”
Requirements
- Node.js
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- For each candidate, classify whether it is public
- For internal candidates, refactor the type from optional to required nullable
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
Ships 1 file in scripts/ (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
bunbunx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use bunx, which can reach the network depending on how they are called.
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
Nullable New Params loads about 1k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 443 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 443 words (~1,036 tokens).
“Use this skill when a change added a new parameter or type member as optional. In internal Remotion code, new inputs must be required and nullable so every caller makes an explicit choice.”
