Use them to create or modify a Ulanzi plugin, choose between HTML and Node.js modes, structure actions and settings screens, and follow the manifest format.

They reduce guesswork about where plugin code belongs and how an app should be organized for the supported controller devices.

Token cost

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	$0.04619	$0.04619
Opus 5.5	$0.01848	$0.01848

Security

Grade A, and why

ulanzi-studio-plugin-skill copilot-instructions.md scanned grade A with 2 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 2mo 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

To check CORS: `curl -sI "URL" | grep -i "access-control"`

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

`child_process.exec`, a `.bat`, or PowerShell is a command-injection target. Whitelist it first -

Ulanzi Studio Plugin Development

Build plugins for Ulanzi D200H / D200 / D200X stream controllers using the Ulanzi Studio SDK.

TRIGGER when: user asks to create a Ulanzi Studio plugin/app, build a stream deck action, or modify an existing Ulanzi plugin.

Plugin Architecture

Two runtime modes (choose one per plugin):

Mode	Entry Point	Use Case
HTML	`plugin/app.html`	Canvas drawing, UI-driven, simpler setup
Node.js	`plugin/app.js`	System access, file I/O, complex logic

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.
