What it does

Kuri iOS is an agent skill from justrach/kuri. Use kuri-ios to drive iOS Simulators from the CLI — list sims, boot/shutdown, navigate Safari to URLs (openurl), launch and terminate apps by bundle id, capture PNG screenshots, list installed apps, and (on the Simulator only) tap, doubletap, longpress, swipe/pan, and type via native CGEvent into the Simulator window. Real iPhones over USB are supported for listing and launch/terminate via usbmuxd + xcrun devicectl. Tap/swipe/type/uitree on real devices and uitree on the Simulator are NOT supported in v1 (require…

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Mobile testing and debugging. It works with iOS, Android and macOS. The repository describes itself as: Browser automation, web crawling, and iOS + Android device control for AI agents. Zig-native, token-efficient CDP snapshots, HAR recording, native adb wire-protocol client, and a…

When your agent uses it

  • Phrases include screenshot the iPhone sim
  • Tap on iOS simulator
  • Doubletap iOS sim
  • Long press iOS sim

Example prompts

  • “screenshot the iPhone sim”
  • “tap on iOS simulator”
  • “doubletap iOS sim”
  • “/kuri-ios”

What it can do on your machine

Read from SKILL.md and the folder at commit bc40000. 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:

    • xcrun
    • xcodebuild

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • news.ycombinator.com

    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

Kuri iOS loads about 1.7k tokens when it runs. Until then it costs about 230 tokens; SKILL.md has 711 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~230
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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); 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 711 words (~1,700 tokens).

“Drive iOS Simulators (and, where possible, real iPhones) through the kuri ios subcommand. Implementation lives in kuri-mobile/src/ios/ and the main kuri binary forwards kuri ios … to the kuri-mobile binary.”
