What it does
Simulators Emulators is an agent skill from championswimmer/TwoFac. How to list, pick, and boot Android emulators and iOS simulators for local app runs.

It sits in Mobile, covering Mobile testing and debugging. It works with Android and iOS. The repository describes itself as: 2FA Authenticator app that works on mobile, web, desktop, watches and CLI!
When your agent uses it
- Tasks that involve Mobile testing and debugging
Example prompts
- “/simulators-emulators”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 1360a71. 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 3 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
nodeadbxcrunrgxcodebuild
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
Simulators Emulators loads about 1.3k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 452 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 452 words (~1,313 tokens).
“Use this skill to discover local Android emulators and iOS simulators, pick a target interactively, and boot it before running the app.”
