iterate-webapp-game

iterate-webapp-game is a skill for Claude Code from facebook/meta-wearables-webapp. It costs 207 tokens per session (6,854 once invoked), scanned A, original, no licence file.

A browser-based workflow for repeatedly testing and improving a web game. It uses Chrome DevTools Protocol, a browser control interface, to load the game, interact with it, take screenshots, inspect state, and read console errors while code changes are made.

In plain words
What is it for?
Use it to test controls, inspect game state, capture screenshots, find browser errors, and verify a completed Meta Display Glasses web game.
Why use it?
It replaces much of the manual cycle of running a game, checking its behaviour, changing code, and checking again. A final verification pass also helps expose problems before the build is considered finished.

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.

Security

Grade A, and why

iterate-webapp-game scanned grade A with 1 finding 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 29d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/cdp.mjs, scripts/frame-stats.mjs, scripts/setup-cdp.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
