- Calls xcrun, bun and bunx; needs LIM_API_KEY
What it does
This is the mobile counterpart of a browser-based verification skill. Input goes through Maestro, evidence comes from `simctl` screenshots and recordings, and state comes from the real local API and relay, with `host-states.sh` as a working example. Six rules define valid evidence: use the real screen rather than a preview route, drive state by changing services instead of seeding the query cache, run an edge pass before reporting tested, never show an unknown state as a negative, catch brief flashes with a recording, and confirm a red check in CI before blaming main.
The edge pass covers cold start, a stopped dependency and its recovery, backgrounding and resuming, rapid state flapping, a very long name, a long-string locale such as German, a CJK locale and the largest text size, and the report says which of these were run. The mechanics section starts services in Superset terminals, explains the expired Neon branch failure and runs the relay in a loop because `wrangler dev` exits when a client aborts. A stand-in host replaces a second machine.
When your agent uses it
- Reproducing or edge-testing a mobile bug in the real app on the simulator
- Checking how the app behaves when the relay or API goes down and comes back
- Producing screenshot and recording evidence for a mobile change
Example prompts
- “Verify the new host status banner on the iOS simulator, including a relay outage.”
- “Edge-test the mobile screen with a very long host name and the largest text size.”
- “Reproduce the offline flash on launch and record it.”
Requirements
- macOS with an iOS simulator and `xcrun simctl`
- Maestro for driving the app
- The local Superset API and relay
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Use the real screen. Sign in and reach the screen the way a user does. A temporary preview
- Drive state through real services. Change what the app sees by changing the local API or
- Run the edge pass before reporting "tested". The main path is not the test. At minimum
- Never show "unknown" as a negative. A query that is pending or failed has not said "offline",
- Catch flashes with a recording. A screenshot taken after a sleep cannot show a state that
- Attribute failures correctly. Before reporting that a check is red on main, confirm it in CI.
What it can do on your machine
Read from SKILL.md and the folder at commit 6b94a61. 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:
xcrunbunbunxffmpegwranglercurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use bunx, wrangler and curl, 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 these keys or tokens, usually read from environment variables:
LIM_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mobile Simulator Verification loads about 2.1k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 1,035 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:50
e lines under `# Workspace Database` in `.env`. - NoteMentions a .env fileSKILL.md:120
they take precedence over the root `.env`.
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 1,035 words (~2,127 tokens).
“The mobile counterpart to cdp-verification. There is no CDP on a phone: input goes through Maestro, evidence comes from simctl screenshots and recordings, and state comes from the real local API and relay. "Rules" is what counts as valid evidence…”

Can I use Mobile Simulator Verification in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add superset-sh/superset --skill mobile-sim-verification -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mobile-sim-verification, .gemini/skills/mobile-sim-verification, .github/skills/mobile-sim-verification and .opencode/skills/mobile-sim-verification in your project.
What does Mobile Simulator Verification need to run?
Going by SKILL.md and its folder, Mobile Simulator Verification needs the command-line tools its instructions call (xcrun, bun, bunx, ffmpeg, wrangler and curl) and credentials named LIM_API_KEY. Our summary lists: macOS with an iOS simulator and `xcrun simctl`; Maestro for driving the app; The local Superset API and relay.
Does Mobile Simulator Verification access the network?
SKILL.md contains no URLs. Its commands use curl, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Mobile Simulator Verification safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Mobile Simulator Verification use?
Mobile Simulator Verification has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Mobile Simulator Verification use?
About 2.1k tokens (SKILL.md is roughly 8.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
